To solve the equation 8 x five sixths, we first convert the fraction to a decimal by dividing the numerator (5) by the denominator (6), which gives us 0.83.

We then multiply 8 by 0.83 to get the final answer of 6.64. Therefore, 8 x five sixths = 6.64.

In general, to multiply a whole number by a fraction, we can convert the fraction to a decimal and then multiply the whole number by the decimal.

Alternatively, we can convert the whole number to a fraction with a denominator of 1 and then multiply the two fractions by cross-multiplying and simplifying.

In this case, we could also write 8 as 8/1 and multiply it by 5/6 to get (8 x 5)/(1 x 6) = 40/6, which simplifies to 6 and 4/6 or 6.67 (rounded to two decimal places). However, converting the fraction to a decimal is often simpler and more practical.

Answer:

Step-by-step explanation:

An obtuse angle has a measure between 90 and 180 degrees. Looks like S and Q have obtuse angles, Its impossible to be sure unless you measure them with a protractor.

The particular solution is [tex]y(t) = (1/2c) (t^2/2 + t/2 + 1/2c) + (2 - 1/(4c))e^(-2ct)[/tex].

[tex]dy/dt + 2cy = t^2 + 1[/tex]

To find the general solution of this differential equation, we can start by finding the integrating factor, which is given by:

I(t) = e^(∫2c dt) = [tex]e^(2ct)[/tex]

Next, we can multiply both sides of the differential equation by the integrating factor I(t):

[tex]e^(2ct) dy/dt + 2ce^(2ct) y = (t^2 + 1) e^(2ct)[/tex]

We can now recognize the left-hand side as the product rule of the derivative of the product of y and I(t):

[tex](d/dt)(y e^(2ct)) = (t^2 + 1) e^(2ct)[/tex]

Integrating both sides with respect to t gives:

[tex]y e^(2ct) = ∫(t^2 + 1) e^(2ct) dt + C[/tex]

The integral on the right-hand side can be solved using integration by parts, and we get:

∫([tex]t^2[/tex] + 1) [tex]e^(2ct) dt = (1/2c) e^(2ct) (t^2/2 + t/2 + 1/2c) + K[/tex]

where K is an arbitrary constant of integration.

Substituting this expression back into the previous equation, we get:

[tex]y e^(2ct) = (1/2c) e^(2ct) (t^2/2 + t/2 + 1/2c) + K[/tex]

Dividing both sides by e^(2ct), we obtain the general solution:

[tex]y(t) = (1/2c) (t^2/2 + t/2 + 1/2c) + Ke^(-2ct)[/tex]

where K is an arbitrary constant.

To find the particular solution that satisfies y(0) = 2, we can substitute t = 0 and y(0) = 2 into the general solution and solve for K:

[tex]y(0) = (1/2c) (0^2/2 + 0/2 + 1/2c) + Ke^(0)[/tex]

2 = 1/(4c) + K

Solving for K, we get:

K = 2 - 1/(4c)

Substituting this value of K back into the general solution, we get the particular solution:

[tex]y(t) = (1/2c) (t^2/2 + t/2 + 1/2c) + (2 - 1/(4c))e^(-2ct)[/tex]

It would take approximately 20 hours for the bacteria to triple in number.

Given that the bacteria population doubles every 10 hours, we can use exponential growth to determine the time it would take for the population to triple.

Let's represent the initial population as P0 and the time it takes for the population to triple as t.

Using the concept of exponential growth, we can express the population at time t as P(t) = P0 * 2^(t/10).

Since we want the population to triple, we set P(t) = 3 * P0:

3 * P0 = P0 * 2^(t/10).

We can cancel out P0 from both sides of the equation:

3 = 2^(t/10).

To solve for t, we can take the logarithm of both sides. Using the base-2 logarithm (log2) gives us:

log2(3) = t/10.

Using a calculator, we find that log2(3) is approximately 1.585.

Now, we can solve for t:

1.585 = t/10.

Multiplying both sides of the equation by 10 gives us:

15.85 = t.

Rounding to the nearest hour, the time it would take for the bacteria population to triple is approximately 16 hours.

Therefore, the bacteria population would take approximately 20 hours to triple in number.

For series Σ a(-1)^(k+1)k!, convergence depends on the limit of |a(k+1)/a(k)|. For series Σ ka sin(2), it diverges.

Consider the series Σ a(-1)^(k+1)k!, where a is a sequence of real numbers.

To determine the convergence of this series, we can use the ratio test

lim┬(k→∞)⁡〖|a(k+1)(-1)^(k+2)(k+1)!|/|ak(-1)^(k+1)k!| = lim┬(k→∞)⁡〖(k+1)|a(k+1)|/|a(k)||〗

If this limit is less than 1, then the series converges absolutely. If the limit is greater than 1, the series diverges. If the limit is equal to 1, then the test is inconclusive.

Let's evaluate the limit

lim┬(k→∞)⁡〖(k+1)|a(k+1)|/|a(k)||〗 = lim┬(k→∞)⁡〖(k+1)!/(k!k)|a(k+1)/a(k)||〗 = lim┬(k→∞)⁡〖(k+1)/(k)|a(k+1)/a(k)||〗

Since lim┬(k→∞)⁡〖|a(k+1)/a(k)||〗 exists, we can apply the ratio test again:

if the limit is less than 1, the series converges absolutely.

if the limit is greater than 1, the series diverges.

if the limit is equal to 1, the test is inconclusive.

Therefore, we can classify the series Σ a(-1)^(k+1)k! as either absolutely convergent, conditionally convergent, or divergent depending on the value of the limit.

Consider the series Σ ka sin(2), where a is a sequence of real numbers.

To determine the convergence of this series, we can use the alternating series test, which states that if a series Σ (-1)^(k+1)b(k) is alternating and |b(k+1)| <= |b(k)| for all k, and if lim┬(k→∞)⁡〖b(k) = 0〗, then the series converges.

In this case, we have b(k) = ka sin(2), which is alternating since (-1)^(k+1) changes sign for each term. We also have

|b(k+1)|/|b(k)| = (k+1)|a|/k < k|a|/k = |b(k)|/|b(k-1)|

Therefore, |b(k+1)| <= |b(k)| for all k. Finally, we have

lim┬(k→∞)⁡〖b(k) = lim┬(k→∞)⁡〖ka sin(2)〗 = ∞〗

Since the limit does not exist, the series diverges.

Therefore, we can classify the series Σ ka sin(2) as divergent.

What is ratio ?

In mathematics, a ratio is a comparison of two quantities, often expressed as a fraction. Ratios can be used to describe how two quantities relate to each other, and they can be used to make predictions and solve problems in a variety of contexts.

The ratio of silver to copper in the platter is 37:3 by mass, which means that for every 37 grams of silver, there are 3 grams of copper.

Let's call the mass of silver in the platter "s" and the mass of copper "c". We know that the total mass of the platter is 600 grams, so:

s + c = 600

We also know that the ratio of silver to copper is 37:3, which means that:

s÷c = 37÷3

We can use this second equation to solve for s in terms of c:

s:c = 37:3

s = (37÷3)c

Now we can substitute this expression for s into the first equation:

s + c = 600

(37÷3)c + c = 600

(40÷3)c = 600

c = (3÷40) * 600

c = 45

Therefore, the mass of copper in the platter is 45 grams, which corresponds to option (B).

The equation of the tangent line to the curve x² + x²y² + y = 1 at the point where x=-1 is (-dx/dy + 2)/(1 - √5)(x + 1). The interval of concavity for f(x) = xlnx is (0, ∞) and there are no points of inflection.

To find the equation(s) of the tangent line(s) to the curve x² + x²y² + y = 1 at x = -1, we need to find the derivative of the curve with respect to x, i.e.,

2x + 2xy²(dx/dy) + dy/dx = 0

At x = -1, we get

-2 + 2y²(dy/dx) + dx/dy = 0

dy/dx = (-dx/dy + 2)/(2y²)

Now, substituting x = -1 in the curve, we get

1 - y + y² = 0

Solving for y, we get

y = (1 ± √5)/2

Substituting y = (1 + √5)/2 in the equation for dy/dx, we get

dy/dx = (-dx/dy + 2)/(2(1 + √5)/4) = (-dx/dy + 2)/(√5 + 1)

Therefore, the equation of the tangent line to the curve at x = -1, y = (1 + √5)/2 is

y - (1 + √5)/2 = (-dx/dy + 2)/(√5 + 1)(x + 1)

Similarly, substituting y = (1 - √5)/2 in the equation for dy/dx, we get

dy/dx = (-dx/dy + 2)/(1 - √5)

Therefore, the equation of the tangent line to the curve at x = -1, y = (1 - √5)/2 is

y - (1 - √5)/2 = (-dx/dy + 2)/(1 - √5)(x + 1)

To find the intervals of concavity and any point(s) of inflection for f(x) = xlnx, we need to find the second derivative of the function with respect to x, i.e.,

f''(x) = (d²/dx²)(xlnx) = d/dx(lnx + 1) = 1/x

Now, to find the intervals of concavity, we need to find the values of x for which f''(x) > 0 and f''(x) < 0. We have

f''(x) > 0 when x > 0, which means the function is concave up on (0, ∞).

f''(x) < 0 when x < 0, which means the function is concave down on (0, ∞).

To find any point(s) of inflection, we need to find the values of x for which f''(x) = 0. However, in this case, f''(x) is never equal to zero. Therefore, there are no points of inflection for the function f(x) = xlnx.

Answer:

k = -3.

Step-by-step explanation:

To answer this question, we need to use our own knowledge and information. Adding a constant k to a function f(x) shifts the graph of f(x) vertically by k units. If k is positive, the graph moves up. If k is negative, the graph moves down. The value of k can be found by comparing the y-coordinates of corresponding points on the graphs of f(x) and g(x). For example, if g(x) = f(x) + 2, then the graph of g(x) is 2 units above the graph of f(x), and any point (x, y) on f(x) corresponds to a point (x, y + 2) on g(x). Therefore, the answer is: k is the vertical shift of the graph of f(x) to get the graph of g(x). It can be found by subtracting the y-coordinate of a point on f(x) from the y-coordinate of the corresponding point on g(x).

Looking at the graph given, we can see that the graph of g(x) is below the graph of f(x), which means that k is negative. We can also see that one point on f(x) is (0, 3), and the corresponding point on g(x) is (0, 0). Using the formula above, we get:

k = y_g - y_f

k = 0 - 3

k = -3

Therefore, the correct option is k = -3.

The particular solution with the given initial condition is:

To find the particular solution, we need to first separate the variables in the differential equation:

[tex]dy/y = (2/3)x dx[/tex]

Next, we integrate both sides:

[tex]ln|y| = (1/3)x^2 + C[/tex]

where C is the constant of integration.

To find the value of C, we use the initial condition f(-4) = 5:

[tex]ln|5| = (1/3)(-4)^2 + C[/tex]
[tex]ln|5| = (16/3) + C[/tex]
[tex]C = ln|5| - (16/3)[/tex]

Therefore, the particular solution is:

[tex]ln|y| = (1/3)x^2 + ln|5| - (16/3)[/tex]
[tex]ln|y| = (1/3)x^2 + ln|5/ e^(16/3) |[/tex]
[tex]y = ± (5/ e^(16/3)) * e^(x^2/3)[/tex]

However, since we know that f(-4) = 5, we can eliminate the negative solution and obtain:

[tex]y = (5/ e^(16/3)) * e^(x^2/3)[/tex]

So the particular solution with the given initial condition is:

The amount of water needed for 1/3 cup of rice, is 3/4 cups of water.

The problem asks us to find out how much water is needed for 1/3 cup of rice, given that 2 1/4 cups of water are needed for 1 cup of rice. To solve this problem, we can use a proportion.

A proportion is an equation that says two ratios are equal. In this case, we want to set up a proportion that relates the amount of water needed to the amount of rice.

Let's start by writing down what we know. We know that for 1 cup of rice, we need 2 1/4 cups of water. We can write this as a ratio:

2 1/4 cups water : 1 cup rice

Now we want to figure out how much water we need for 1/3 cup of rice. Let's call the amount of water we need "x" (we don't know what it is yet), and set up another ratio:

x cups water : 1/3 cup rice

We can now set up our proportion by equating these two ratios:

2 1/4 cups water : 1 cup rice = x cups water : 1/3 cup rice

To solve for x, we can cross-multiply and simplify. Cross-multiplying means we multiply the numerator of one ratio by the denominator of the other ratio, like this:

(2 1/4 cups water) * (1/3 cup rice) = (x cups water) * (1 cup rice)

To simplify this, we can convert the mixed number 2 1/4 to an improper fraction:

2 1/4 = 9/4

Now we can substitute these values and multiply:

(9/4 cups water) * (1/3 cup rice) = (x cups water) * (1/1 cup rice)

Multiplying the fractions on the left-hand side gives:

9/12 cups water = (x cups water) * (1/1 cup rice)

Simplifying the fraction on the left-hand side gives:

3/4 cups water = x cups water

So we have found that x, the amount of water needed for 1/3 cup of rice, is 3/4 cups of water. Therefore, if you have 1/3 cup of rice, you would need to use 3/4 cups of water to cook it.

This means that when 6.4 and 4.07 is added, then we will see numbers of decimal places in each number. 6.4 has 1 number after decimal point and 10.47 has 2.

Hence the result of 6.4 + 10.47 will have a minimum of 2 which is 1 decimal place.

Now, 6.4 + 4.07

= 10.47

Rounding it off from the above-mentioned criteria gives us 10.5 ounces.

Therefore, the total number of ounces of hydrogen peroxide, rounded to up to 1 significant digit after the decimal point, is 10.5 ounces.

An American in the middle 70% of cheese consumption consumes between 23.1 lbs and 41.5 lbs of cheese per year.

To find the amount of cheese consumed by an American in the middle 70% of cheese consumption, we need to find the z-scores that correspond to the lower and upper bounds of the middle 70% and then convert those z-scores back to the original scale of measurement.

First, we need to find the z-score that corresponds to the 15th percentile (lower bound) and the z-score that corresponds to the 85th percentile (upper bound) of the normal distribution. We can use a standard normal table or a calculator to find these values. Using a calculator, we get:

z_15 = invNorm(0.15) = -1.036

z_85 = invNorm(0.85) = 1.036

Next, we can use the formula:

z = (x - mu) / sigma

where x is the amount of cheese consumed by an American, mu is the mean amount of cheese consumed (32.3 lbs), and sigma is the standard deviation (8.7 lbs), to convert the z-scores back to the original scale of measurement:

For the lower bound:

-1.036 = (x - 32.3) / 8.7

x = -1.036 * 8.7 + 32.3 = 23.1 lbs

For the upper bound:

1.036 = (x - 32.3) / 8.7

x = 1.036 * 8.7 + 32.3 = 41.5 lbs

Therefore, an American in the middle 70% of cheese consumption consumes between 23.1 lbs and 41.5 lbs of cheese per year.
