Answer:
C
Step-by-step explanation:
The perimeter of a figure is found by adding the sides of all the figures. The figure has sides 13 and 9. Its height is 4 so each of those sides is about 4 feet. So the perimeter is 13+9+4+4 = 30
C is the best solution.
Step-by-step explanation:
volume of cylinder formula pi*r²*h
radius of 9cm is 4.5 as 9/2
so 4.5²*15 is 303.75cm
303.75*pi is 303.75picm³
Answer:
180
Step-by-step explanation:
im sure that is 180 so if you did not believe me solve that and be ready for your task and your brain
Answer: y = 1/8x+1
y=mx+b is slope intercept form
given m = 1/8 and a point we can find b by plugging in what we have
1=1/8(8)+b
1=1b
b=1
So then we know m = 1/8 and b = 1
y=1/8x+1 is the answer
X²+3x-21=0
1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2
2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21
Answer: the product of the 2 solutions of this equation is -21
