Answer:

2677

Step-by-step explanation:

Let's make this easier first of all:

a^2-y^3(a-y^2)y^2

a^2-y^5(a-y^2)

a^2-ay^5+y^7

(-2)^2-(-2)(3)^5+3^7

4-(-2*243)+2187

4-(-486)+2187

4+486+2187

490+2187

Holly deposited $10,000 in an investment account. After 6 years the account is worth approximately $13,400. Which formula repres
Nady [450]
Formula for exponential growth is:

A = P(1+r)^t

Where A is the resulting amount, P is the initial value, r is the rate, and t is the time passed.

Filling this out for this situation gets you:

13400 = 10000(1+r)^6

Solving for r:

Divide 13400 by 10000

1.34 = (1+r)^6

Take the 6th root of both sides...
1 + r = 1.05

No more work is needed, since you aren’t solving for r.

Full equation:
V = 10000(1.05)^t

For each set of three measures, determine if they can be angle measures of a triangle.
sp2606 [1]

The sum of the angles in the triangle must be equals to 180 degrees for it to be the angle measure of a triangle.

<h3>Angles in a triangle</h3>

The sum of angles in a triangle is equals to 180 degrees.

Therefore, adding up the three angles in a triangle must be equals to 180 degrees.

Hence,

42 + 34 + 56 = 132 degrees

This does not form a triangle.

35 + 80 + 65 = 180 degrees

This can be the angle measure of a triangle.

15 + 51 + 24 = 90 degrees

This cannot be the angle measure of a triangle.

18 + 42 + 120  = 180

This can be the angle measure of a triangle.
