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

Ariana has $1.40 worth of nickels and dimes. She has twice as many nickels as dimes. Determine the number of nickels and the num

navik [9.2K]

Answer:

14 nickels

7 dimes

Step-by-step explanation:

1. find out how many dimes there has to be to get $1.40

1 dime= .10

1.40/.10=14 dimes

14/2=7

so there are 7 dimes

since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70

.70/.05=14

there are 14 nickels

proof:

$0.10(7)+$0.05(14)= $1.40

hope this helps!
