Have you learned about the Pythagorean theorem? a² + b² = c² . . . you should teach them about this.
Answer:
J
A=7.07cm^2
Step-by-step explanation:
A= (pi)(r^2)
diameter=3
radius= 1/2 of the diameter = 1.5
pi = approximately 3.14
A= (3.14) (1.5)^2
A= 7.065 ----> rounds to 7.07
Y=3(x²+10x)+71
Now we need to complete square for (x²+10)
It should look like this
a²+2ab+b²=(a+b)²
y=3(x²+2*5x+5²)-3*5²+71
y=3(x+5)²-75+71
y=3(x+5)²-4
Vertex has coordinates x=-5, y=-4.
Vertex in this case is the extreme value (-5,-4)
