Answer: P = 1/2q-r

Step-by-step explanation:

2p + 2r = q

2p = q - 2r

p = 1/2q - r

Answer:

p=(q-2r)/2

Step-by-step explanation:

First, you must isolate the variable p, as you are solving for it. To do this, you substract 2r from both sides. Then, you are left with 2p=q-2r. To fully isolate p, you must divide both sides by 2. Lastly, you are left with p=(q-2r)/2.

Hope this helps :)

Identify the initial value in each formula below, and state whether the formula models exponential growth or

kaheart [24]

Answer:

Intial Value: f(t) = 2 , Exponential Growth

Step-by-step explanation:

To find the initial value, all we have to do is find the value of f(t) at t = 0

In this case the given equation becomes

$f(t) = 2(\frac{5}{3})^0$

from the law of indices we know that any number with the power 0 is equal to 1 (except 0 with the power 0)

$a^0 = 1$

hence the above equation becomes

$f(t) = 2(1)\\ f(t) = 2$

so the initial value is 2.

To find out whether this is exponential growth or exponential decay we need to see whether the base value of the power t is less than 1 or greater than 1, i.e. from

$(\frac{5}{3} )^t$

$\frac{5}{3}$ > 1 or $\frac{5}{3}$ < 1

if the value is greater, then with each increment in power, the total value will increase while if it is less than 1 then with each increment in power the total value will decrease.

Hence since $\frac{5}{3}$ > 1 then this is an exponential growth

Growth factors for the population of Atlanta in the past five years have been 1, 2, 3, 4 , and 5. The geometric mean is a. . b.

choli [55]

Answer:

The geometric mean of given data is approximately 2.6051

Step-by-step explanation:

We are given the following data in the question:

1, 2, 3, 4, 5.

We have to find the geometric mean.

Formula:

$(a_1\times a_2\times... \times a_n)^{\frac{1}{n}}$

Putting the values, we get,

$\text{Geometric mean} = (1\times 2\times 3\times 4 \times 5)^{\frac{1}{5}}\\=(120)^{\frac{1}{5}} \approx 2.6051$

Thus, the geometric mean of given data is approximately 2.6051

A circle with a radius of 15 yards contains a sector with an area of 609 yde. Find the measure of

kondaur [170]

Answer: 310.3° or 5.41 radians.

Step-by-step explanation:

The area of a circle of radius R is calculated as:

A = pi*R^2

Now, if we have a sector of an angle θ degrees, the area of that sector is:

A = (θ/360°)*pi*R^2

In this case, we know that:

R = 15yd

And the area of the sector is 609 yd^2

Then we can replace these two values in the equation to get:

609yd^2 =(θ/360°)*3.14*(15yd)^2

(609yd^2)*360°/(3.14*(15yd)^2) = θ = 310.3°

And we want the angle also in radians.

We know that:

3.14 rad = 180°

(3.14 rad/180°) = 1

Then:

310.3° = 310.3°*(3.14 rad/180°) = (310.3°/180°)*3.14 rad = 5.41 radians.
