The population of a city can be modeled by the expression P(1.06)^t where T represents the number of years since 1990 and P represents the population in 1990. Which statement is correct

Answers

Answer 1

Answer:

D. the yearly growth rate of the population is 6%

Step-by-step explanation:

Given the exponential growth function : P(1.06)^t

Recall the general form of the function :

P(t) = P0(1 + r)^t

Where, P0 = Initial population ; r = rate ; t = time

Comparinv the equation and the function Given :

We can Evaluate :

1 + r = 1.06

r = 1.06 - 1

r = 0.06

To percentage :

0.06 * 100%

= 6%

[tex] \sin(x) = \frac{7}{15} \\ x = { \sin}^{ - 1} ( \frac{7}{15} ) \\ x = 27.8 \degree[/tex]

Answer:

28°

Step-by-step explanation:

For this problem, we are given the leg length opposite the angle x and the hypotenuse. This perfectly describes the trig function, sine. We can set up an equation:

opposite / hypotenuse = sin(x°)

We can substitute in the sides:

7 / 15 = sin(x°)

Now, to find x, we can evaluate the inverse of sin or arcsin on the ratio 7 / 15

arcsin(7 / 15) = x° = 27.81813928°

This rounds to 28°

Answers

Answer:

48.25

Step-by-step explanation:

When finding an area of a triangle it is area = base times height divided by 2.

AKA a =bh1/2

We can do that for all sides in this equation.

For the bottom we can do:

5*4.3=21.5       21.5/2 = 10.75

For one side we can do:

5*5 = 25           25/2 = 12.5

12.5 = one side, but there are three so,

12.5*3 = 37.5

37.5 + 10.75 = 48.25

Step-by-step explanation:

Decagon is a 10-sided polygon.

Formula to find the sum of interior angles of a n-sided polygon is  

=  (n - 2) ⋅ 180°

By using the formula,  sum of the interior angles of the given decagon (10-sided polygon) is  

=  (10 - 2) ⋅ 180°

=  8 ⋅ 180°

=  1440°
