8+(x/-9)=9 subtract 8
x/-9= 1 multiply by -9
x= -9
Answer:
f(-3) = -9.
Step-by-step explanation:
The equation of the curve in vertex form is:
f(x) = a(x + 3)^2 - 9 a is positive as the parabola opens up.
It passes through the point (1.5, 4), so
4 = a(1.5 + 3)^2 - 9
20.25a = 13
a = 13/20.25
a = 0.6420.
So the equation of the graph is
0.6420(x + 3)^2 - 9.
f(-3) = 0.6420(-3 + 3)^2 - 9
= 0.642*0 - 9.
= -9.
Example:
38 rounds to 40
6 rounds to 10
10+40 = 50
Step-by-step explanation:
radius of the cone = 3.5cm
height of cone = 12 cm
volume of cone = pie × r ^2 × h
= 1/3 × 22/7 × 35/10× 35 /10 ×
12 = 154 cm^3
