The amount of a sample remaining after t days is given by the equation p(1) - al2 is: 74 days.

Using this formula

P(t)=A×(1/2)^t/h

Let plug in the formula

0.6x=x ×(1/2)^t/h

0.6=(1/2)^t/100

Hence:

Log0.6=Log(1/2)^t/100

Log 0.6=t/100× log0.5

Log 0.6/Log0.5×100=t

-0.2218487/-0.30102999×100=t

The probability that the cat lands on its feet both times it falls out of a tree is 0.85

The probability that the cat lands on its feet is given as:

P(Feet) = 0.92

The probability that it lands on its feet twice is calculated using:

P = P(Feet) * P(Feet)

So, we have:

P = 0.92 * 0.92

Evaluate

P = 0.85

Hence, the probability is 0.85

Answer:

Step-by-step explanation:

This is a geometric sequaence and each term is obtatained by multiplying the previous number with the common ratio 'r'

          [tex]\sf \boxed{r = \dfrac{second \ term }{first \ term}}[/tex]

[tex]\sf r =\dfrac{4}{(-2)}[/tex]

r = -2

                First of all, let's identify what kind of sequence this is.

The two main types of sequences are:

In the given sequence, we use multiplication, so we're dealing with a [tex]\textit{geometric sequence}[/tex].

In order to get to the next term, we multiply by -2.

So in order to find the next two terms of the sequence, we take the previous term and multiply it by -2 as follows:

16•(-2)=-32

We've found the 5th term of the geometic sequence.

Now let's find the 6th:

-32•(-2)=64 (the product of a negative and a negative results in a positive)

The next two terms in the sequence are -32 and 64.

Answer:

Step-by-step explanation:

Area of shaded region

  When we subtract the area of the circle from the area of square, we get the area of the 4 corners. When we divide that by 2, we get the area of 2 corners(shaded).
[tex]\sf \boxed{\text{Area of the shaded region =$\dfrac{Area \ of \ square - area \ of \ circle}{2}$}}[/tex]

Area of square = side *side

                          = 8 * 8

                          = 64 square inches

     diameter of the circle = side of the square

                                     d = 8 in

                                      r = 8/2 = 4 in

   [tex]\sf \text{Area of circle = \pi r^2}[/tex]  Area of circle = πr²

                            = 3.14 * 4 * 4

                            = 50.24 square inches

[tex]\sf \text{Area of shade region = \dfrac{64 - 50.24 }{2}}[/tex]

[tex]\sf \text{Area of the shade region = $\dfrac{64 - 50.24}{2}$}[/tex]

Answer:

  4.34 inches

Step-by-step explanation:

You want the diameter of a cylinder if the stroke length is 4.5 in, and 6 of them have a volume of 400 in³.

Filling the given values into the formula, we have ...

  400 = π/4(d²)(4.5)(6)

  d² = 400(4)/(4.5·6π) . . . . . . . . . divide by the coefficient of d²

  d = 40/(3√(3π)) ≈ 4.34 . . . . . . . take the square root

The diameter is about 4.34 inches.

Answer:

  (a)  r < 37 or r ≥ 42

Step-by-step explanation:

Translating the given relations to math symbols, we have ...

  "less than 37 minutes"  ⇒  r < 37

  "no less than 42 minutes"  ⇒  r ≥ 42

__

Written as a single statement, this is ...

  r < 37 or r ≥ 42

Additional comment

The solution regions are disjoint, so an "or" statement must be used. The form ...

  37 > r ≥ 42

cannot be used, because it is false that 37 > 42.

Using separation of variables for the differential equation, it is found that:

a) The differential equation is: [tex]\frac{dP}{dt} = kP[/tex]

b) The solution is: [tex]P(t) = 5000e^{kt}[/tex]

c) In 6 months, the population is: [tex]P(6) = 5000e^{6k}[/tex]

Population of fishes in a pond is directly proportional to amount of fishes present in the bond, hence the differential equation is:

[tex]\frac{dP}{dt} = kP[/tex]

In which k is the growth rate.

In separation of variables, we place all the factors of y on one side of the equation with dy, all the factors of x on the other side with dx, and integrate both sides.

Hence, for the differential equation in this problem:

[tex]\frac{dP}{dt} = kP[/tex]

[tex]\frac{dP}{P} = k dt[/tex]

[tex]\int \frac{dP}{P} = \int k dt[/tex]

[tex]\ln{P} = kt + P(0)[/tex]

[tex]P(t) = P(0)e^{kt}[/tex]

In which P(0) = 5000 is the initial population, hence:

[tex]P(t) = 5000e^{kt}[/tex]

In 6 months, the population is:

[tex]P(6) = 5000e^{6k}[/tex]

The best estimate for the average number of sunlight hours she can expect each day in June is 9.9 hours

To answer the question, we need to know what a regression model is

A regression model is an equation or model that shows if there is a relationship between two variables.

Now, given that Yuki uses the regression model y = -2.8sin(0.65x + 120.2) + 12.2 to calculate the average number of sunlight hours per month, where x = 1 represents January.

Since we need to determine the average number of sunlight hours she can expect each day in June. Since June is the sixth month, we substitute x = 6 into the equation.

So, y = -2.8sin(0.65x + 120.2) + 12.2

y = -2.8sin(0.65(6) + 120.2) + 12.2

y = -2.8sin(3.9 + 120.2) + 12.2

y = -2.8sin(124.1) + 12.2

y = -2.8(0.8281) + 12.2

y = -2.32 + 12.2

y = 9.88

y ≅ 9.9

So, the best estimate for the average number of sunlight hours she can expect each day in June is 9.9 hours
