Answer:
The square root of 160 is between 12 and 13 because 12x12=144 but 13x13=169. 160 is on between these so it must be between 12 and 13.
40 is a square root of 1600 because the equation looks like this:
40x40 It has 2 zeros, so the answer also has 2 zeros. Hence why it is 1600 not 160.
Answer:
yes, the inequality is true.
Step-by-step explanation:
15 + 9 = 24
24 > 21
What does z equal? Is there a picture you could add to this
Given:
The yield of strawberries per acre is
S = -(w - 2)² + 50
where
S = number of pints of strawberries per acre
w = acre-feet of water
Strawberries sell for $3 per pint
Water costs $5 per acre-feet.
The yield function is the revenue minus the expenses. It is
Y = (S pints)*($3 per pint) - (w acre-ft)*($5 per acre-ft)
Y = -3(w - 2)² -5w + 150 dollars
A graph of the yield function is shown below.
It indicates that
a) the yield is maximum when the acre-feet is about 1.5;
b) the yield increases between zero and 1.5 acre-feet;
c) the yield decreases quickly when the acre-feet exceed 1.5;
d) the yield vanishes when the acre-feet exceed 8.

Step-by-step explanation:
A side of the triangle must be shorter than the sum of the remaining two sides.
He cannot make a triangle with 3, 4, and 8.
