Step-by-step explanation:

1 1/2 = 3/2

3/2 / 1/4 = 3/2 * 4 = 12 / 2 = 6

Answer:

6

Step-by-step explanation:

One recipe uses 1/4 cup of red onions.

They have 1 1/2 cups of red onions.

We need to divide 1 1/2 by 1/4.

First, we convert the mixed numeral into a fraction. Then, to divide by a fraction, we multiply by the reciprocal of the fraction.

[tex] 1 \dfrac{1}{2} \div \dfrac{1}{4} = [/tex]

[tex] = \dfrac{1 \times 2 + 1}{2} \div \dfrac{1}{4} [/tex]

[tex] = \dfrac{3}{2} \times \dfrac{4}{1} [/tex]

[tex] = \dfrac{12}{2} [/tex]

[tex] = 6 [/tex]

Answer:

It is the odd number 1009

Step-by-step explanation:

Notice that this problem involves the addition of a number "1" per consecutive pair (a number minus the integer that immediately precedes it), so it adds "1" (one) every couple of consecutive numbers.

2018 - 2017 = 1

2016 - 2015 = 1

...

4- 3 = 1

2 - 1 = 1

That means it is the addition of 2018/2 = 1009 numbers "1". This clearly results on the number 1009, which is an odd number.

Answer:

Option D [[tex]y=6.61\,*\,1.55^x[/tex]] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

[tex]y=A\,e^{k\, x}[/tex]

with optimized parameters:

[tex]A \approx 6.6114\,\,\,and\,\,\, k=0.4378321[/tex]

Notice as well that since:

[tex]e^{0.4378321} \approx 1.5490[/tex]

the exponential best fit can also be written:

[tex]y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}[/tex]

and this expression is very close to the last option shown in your list of possible answers

Answer:

length of rectangle = 5

width of rectangle = 5

Area of rectangle = 25

Step-by-step explanation:

Since the length of the rectangle is "x", and the value of the area is given by the product of the length "x" times the width "10-x", indeed, the area "y" of the rectangle is given by the equation:

[tex]y=x\,(10-x)=10x-x^2[/tex]

Now, they tell us that the area of the rectangle is such that coincides with the maximum (vertex) of the parabola this quadratic expression represents. So in order to find the dimensions of the rectangle and therefore its area, we find the x-coordinate for the vertex, and from it, the y-coordinate of the vertex, which is the rectangle's actual area.

Recall that the formula for the x of the vertex of a quadratic of the form :

[tex]y=ax^2+bx+c[/tex]

is given by the formula:

[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]

which in our case gives:

[tex]x_{vertex}=-\frac{b}{2\,a}\\x_{vertex}=-\frac{10}{2\,(-1)}\\x_{vertex}=5[/tex]

Therefore, the length of the rectangle is 5, and its width (10-x) is also 5.

The area of the rectangle is therefore the product of these two values: 5 * 5 = 25

Which should coincide with the value we obtain when we replace x by 5 in the area formula:

[tex]y=10x-x^2\\y=50-(5)^2\\y=50-25\\y=25[/tex]

Answer:   [tex]\bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}[/tex]

Step-by-step explanation:

y = A cos (Bx - C) + D

The minimum is -7 and the max is 7 so A = 7 and D = 0

Period is 7.  Since P = 2π/B then 7 = 2π/B --> B = 2π/7

Nothing was stated about a phase shift so you can use any value for C. I chose C = 0.

Now, input A = 7, B = 2π/7, C = 0, & D = 0 into the equation

[tex]y=7\cos\bigg(\dfrac{2\pi}{7}x-0\bigg)+0\\\\\\\text{Simplify}:\\y=7\cos\bigg(\dfrac{2\pi}{7}x\bigg)[/tex]

Answer:

200

Answer:

x = 50

Step-by-step explanation:

Let x be the original number.

This question can be expressed as:

0.4x = 20

0.4 of the original number is 20.

Now, we can directly solve for x:

4x = 200

x = 50

Answer:

8

Step-by-step explanation:

40 times 0.20 is 8.

You can also use 40 percent of 20, which is also 8, but the original is easier to comprehend.

Answer: VA: x = {-5, 5), HA: y = 0, Zeros: x = 0

Step-by-step explanation:

[tex]f(x) = \dfrac{5x}{x^2-25}[/tex]

Vertical asymptotes: The denominator cannot equal zero.

x² - 25 = 0  

(x - 5)(x + 5) = 0

x = 5, x = -5

Horizontal Asymptote: Let m represent degree of numerator and n represent the degree of the denominator.

For the given equation, m = 1 and n = 2 so we use option 3 --> y = 0

Zeros: Set the equation equal to zero and solve for x.

[tex]0=\dfrac{5x}{x^2-25}[/tex]

Multiply both sides by x²- 25   -->    0 = 5x

Divide both sides by 5       -->          0 = x

Using function concepts, it is found that:

The function is given by:

[tex]f(x) = \frac{5x}{x^2 - 25}[/tex]

Applying the subtraction of perfect squares, the function will be given by:

[tex]f(x) = \frac{5x}{(x - 5)(x + 5)}[/tex]

The zero is the value of x for which:

[tex]f(x) = 0[/tex]

In a fraction, it is when the numerator is zero, thus:

[tex]5x = 0[/tex]

[tex]x = \frac{0}{5}[/tex]

[tex]x = 0[/tex]

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator, thus:

[tex](x - 5)(x + 5) = 0[/tex]

[tex]x = \pm 5[/tex]

The horizontal asymptote is:

[tex]y = \lim_{x \rightarrow \infty} f(x)[/tex]

Hence:

[tex]y = \lim_{x \rightarrow \infty} \frac{5x}{x^2 - 25} = y = \lim_{x \rightarrow \infty} \frac{5x}{x^2} = y = \lim_{x \rightarrow \infty} \frac{5}{x} = 0[/tex]

Answer:

The step to take to avoid fraction is to solve for y in equation 2

Step-by-step explanation:

Given

-9x+ 4y =- 10

-9x+ 3y = 3

Required:

Step for solving using substitution (avoiding fraction)

Let -9x+ 4y =- 10  represent equation 1

and -9x+ 3y = 3 represent equation 2

The following points are to be noted

Having said that, the step to take to avoid fraction is to solve for y in equation 2

Check

[tex]-9x+ 3y = 3[/tex]

Add 9x to both sides

[tex]9x-9x+ 3y = 3 + 9x[/tex]

[tex]3y = 3 + 9x[/tex]

Divide through by 3

[tex]\frac{3y}{3} = \frac{3 + 9x}{3}[/tex]

[tex]y = \frac{3 + 9x}{3}[/tex]

Split fraction

[tex]y = \frac{3}{3} + \frac{9x}{3}[/tex]

[tex]y = 1 + 3x[/tex]

At the point, the expression of y can then be substituted in equation 1

Answer: solve for y in the second equation

True, r represents the distance from a point to the pole when plotting that point in polar coordinates.

Step-by-step explanation:

Given: The statement '' The value of r represents the distance from a point to the pole when plotting that point in polar coordinates ''

To state: whether the given statement is true or false

Solution:

In the cartesian coordinate system, any point is represented by the coordinates  [tex](x,y)[/tex]

In polar-coordinates system, distance of the point from the origin (pole)(r) and the angle [tex](\theta)[/tex] that the line joining the point to the origin makes with the positive  x -axis are used as polar coordinates. Polar coordinates are of form [tex](r,\theta)[/tex]

The attached image in conjunction with the question is shown in the file below.

We can see from the RT segment that the equation given can be expressed as:

[tex]\mathbf{2x+3x = 10}[/tex]

so; if we solve for x ; we have ;

[tex]\mathbf{5x= 10}[/tex]

divide both sides by 5 ; we have:
