Answer: 800 feet²
Step-by-step explanation:
Lets remove the brackets from the function's expression
A(x) = -2x²+80x
So we got the quadratic function and we have to find the x that corresponds to function's maximum. Let it be X max
As we know Xmax= (X1+X2)/2 , where X1 and X2 are the roots of the function A(x)
Lets find X1 and X2
x(80-2x)=0
x1=0 80-2*X2=0
x2=40
So Xmax= (0+40)/2=20
So Amax= A(20)= 20*(80-2*20)=20*40=800 feet²
Answer:
7
Step-by-step explanation:
Look at the order it is in carefully
(18+ 18 +19+ 18 +24+ 21+ 21 +24 +23 +25+ 46 +28+ 21 +19)/14 =325/14≈<span>23.21</span>
Answer:
A man who went by the name, "Pythagoras".
An isosceles triangle has two equal sides.
a= one equal side
b=base
b+2a=35
a=b+4
b+ 2(b+4)=35
b+2b+8=35
3b+8=35
3b=27
b=9
a=13
