Answer:

b -17

Step-by-step explanation:

−a^2 − 3b^3 + c^2 + 2b^3 − c^2 =

= -(3²) - 3(2³) + (-3)² + 2(2³) - (-3)²

= -9 - 3(8) + 9 + 2(8) - 9

= -9 - 24 + 9 + 16 - 9

= -17

Given the parent function f(x) = x^2 describe the translation of the function y=(.2x)^2?
Bad White [126]

Answer:

Option C.

Step-by-step explanation:

Let f(x) = x ^ 2 be a quadratic function

Then we do the function y = f(bx) = (bx) ^ 2

Where b is a real number.

If b> 1 then the function y = (bx) ^ 2 represents a horizontal compression of the function y = x ^ 2  

If  0 Then the function y = (bx) ^ 2 represents a horizontal expansion compression of the function y = x ^ 2 by a factor of \frac{1}{b}

In this case, the equation is:

y = (0.2x) ^ 2 Then:

b = 0.2

0

Thus

y = (0.2x) ^ 2 is a horizontal expansion of the function y = x ^ 2 by a factor of \frac{1}{0.2} = 5.

The correct option is: Option C

You can model that you expect a 1.25% raise each year that you work for a certain company. If you currently make $40,000, how ma
gizmo_the_mogwai [7]

Answer:

94 years

Step-by-step explanation:

We can approach the solution using the compound interest equation

A= P(1+r)^t

Given data

P= $40,000

A=  $120,000

r=  1.25%= 1.25/100= 0.0125

substituting and solving for t we have

120000= 40000(1+0.0125)^t \\\120000= 40000(1.0125)^t

dividing both sides by 40,000 we have

(1.0125)^t=\frac{120000}{40000} \\\\(1.0125)^t=3\\\ t Log(1.0125)= log(3)\\\ t*0.005= 0.47

dividing both sides by 0.005 we have

t= 0.47/0.005\\t= 94
