Answer:
f(-3) = -21
Step-by-step explanation:
To find f(-3), we just need to plug x = -3 into f(x) so:
f(-3) = -4 * (-3)² + 15
= -4 * 9 + 15 = -36 + 15 = -21
Step-by-step explanation:
Use Pythagorean theorem here. To find the height, find the difference of the 2 y's. To find the length, find the difference between the 2 x's.
Length = x2 - x1
Height = y2 - y1
√length^2 + height^2 = distance
√5^2 + 5^2 = √50 = 7.07
Answer:80% of 90 is bigger
Step-by-step explanation:
80% of 90
N= 90/100×80
N= 90/100× 80/100
N=7200/100
N=72
So 80% of 90 is 72
1/2 of 140
70+70=140
So half of 140 is 70.
