Answer:
y = x² - 10x + 41
Step-by-step explanation:
The standard form of a quadratic is ax² + bx + c : a ≠ 0
Given
y = (x - 5)² + 16 ← expand (x - 5)²
= x² - 10x + 25 + 16
= x² - 10x + 41 ← in standard form
use the formula given:
V = pi r^2h
r = 10.55
h = 12.56
V = 3.14 x 10.55^2 x 12.56 = 4391.81 round off to 4392cm^3
answer is D 4392
Answer:
C
Step-by-step explanation:
Okay so on Saturday there is a 30% sale plus she comes early so +10% and that makes 40% off.
10% of 400=40
multiply by 4 to get 40%, 40*4=40%
40%=160
400-160=240
Hope this helps

4 and 5/8=4+5/8=4+0.625=4.625
you can just seperate the fractions and add
