It’s D because since c is to the power of -4 you would move it to the numerator so that it can be to the power of a positive number :)

a city has a population of 340,000 people suppose each year the population grows by 7% what will rhe population be after 12 year
NemiM [27]
So this is going to be an exponential equation, which the format is y=ab^x , in which a is the initial value and b is the growth/decay rate.

In this case, a is going to be 340,000 and b is going to be 107%, or 1.07, since the population is going to be increasing by 7% and the equation is now y=340000(1.07)^x .

Now replace x with 12 and solve.

y=340000(1.07)^{12}

Solve 1.07^{12}, and then if you don't round that answer and multiply it with 340000 you get y=765745 .

Amanda and jamie are standing 25 feet apart and spot a bird in the sky between them the angle of elevation from Amanda is 25 fee
finlep [7]

Answer:

25.2294 feet

Step-by-step explanation:

We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).

First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:

y + 55 + 63 = 180

y = 62°

The relation between the angles and the distances are:

25 / sin(y) = x / sin(63)

25 / 0.8829 = x / 0.8910

x = 25 * 0.8910 / 0.8829 = 25.2294 feet
