Answer:

$1,020

Step-by-step explanation:

There is a $200 difference in the every monthly pay.

Because of this we know that the first month was an amount minus $200.

If we subtract 1220 and 200, you get the pay of 1020 for 0 hours.

Answer:

The average of rate was of 0.4314 cm/day, which means that on average, during this interval, the plant grew by 0.4314 cm each day.

Step-by-step explanation:

Average rate of change:

The average rate of change of a function f(x), from x = a to x = b, is given by:

$A = \frac{f(b)-f(a)}{b-a}$

In this question:

$f(x) = 12(1.03)^n$

From n = 3 to n = 10

$a = 3, b = 10$

$f(b) = f(10) = 12(1.03)^{10} = 16.13$

$f(a) = f(3) = 12(1.03)^{3} = 13.11$

Average rate of change:

$A = \frac{f(b)-f(a)}{b-a} = \frac{16.13-13.11}{10-3} = 0.4314$

The average of rate was of 0.4314 cm/day, which means that on average, during this interval, the plant grew by 0.4314 cm each day.

The ratio of the perimeters of two similar triangles is 3:7. Find the ration of the areas! Please help, I am really not sure. An

PIT_PIT [208]

I don't have a visual I can provide, but the ratio of the areas is the square of the ratio of the perimeters of a 2D figure.

Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.

Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.
