Answer = 1/2 x
Answer:
178.5 m^2
Step-by-step explanation:
Here we see a square and a half circle
Equation: A=bh+πr²
Square: 10*10= 100
Half circle: π5² (it is 5 because the diameter is 10)
A= 25π
A=100+25π
A=178.5
2 ways
1 calcluls
2. algebra
calculus, just take the deritivive and find wher it is 0
y=-0.2x+10
at x=50
sub 50 for x in original
y=250
algebra
for
y=a(x-h)²+k
(h,k) is vertex
k is maximum value
complete the square
y=(-0.1x²+10x)
y=-0.1(x²-100x)
take 1/2 of -100 and square it and add negative and positive inside
-100/2=-50, (-50)²=2500
y=-0.1(x²-100x+2500-2500)
factor perfect square
y=-0.1((x-50)²-2500)
exand
y=-0.1(x-50)²+250
vertex at (50,250)
producing 50 units yeilds a sale price of $250
max price is $250
yes
10² = 10 × 10 = 100
divide 100 by her daily average of 20
= 5
She should be able to read 100 pages in 5 days
