To find the percentage of a number, first, convert it to a decimal and then multiply. 

To convert a percentage to a decimal, move the decimal point over 2 spaces to the left. That makes 80% = 0.80

Then multiply 0.80 by 30.

0.80 • 30 = 24

Peggy got 24 questions correct.

I need help with this question
maw [93]

Answer:

a. 2

b. x^2 + 10x + 26

c. x^2 + 2x + 2

Step-by-step explanation:

For each part, replace x with the value you are given and simplify.

f(x) = x^2 - 2x + 2

a.

f(2) = 2^2 - 2(2) + 2 = 2

b.

f(x + 6) = (x + 6)^2 - 2(x + 6) + 2

= x^2 + 12x + 36 - 2x - 12 + 2

= x^2 + 10x + 26

c.

f(-x) = (-x)^2 - 2(-x) + 2

= x^2 + 2x + 2

Sarah begins at a negative position along the x-axis. Sarah moves in the positive x-direction, turns around and then moves in th
a_sh-v [17]

Answer:

he magnitude of Sarah's displacement is less than the distance she travels

Step-by-step explanation:

Hi!

The magnitude of her displacement is just the difference between her final and initial state, however the distance she traveled is two times the distance she moved in the positive x-direction until she turned around, since she had to move back, plus her displacement.

So:

displacement = |x_{final} -x_{initial}| \\distanceTraveled = 2|x_{return}-x_{initial}| + displacement\\

Since all the terms are positive:

x_{displacement}
