Step-by-step explanation:
Answer:
12
Step-by-step explanation:
This triangle is a 3-4-5 Pythagorean Triple. 9 is 3*3, 15 is 5*3, so b is 4*3, which is 12. Alternatively, you could use the Pythagorean Theorem's converse, sqrt(15^2-9^2), and get 12.
Answer:
Let's solve for f.
fx=5x−3
Step 1: Divide both sides by x.
fx
x
=
5x−3
x
f=
5x−3
x
Let's solve for x.
fx=5x−3
Step 1: Add -5x to both sides.
fx+−5x=5x−3+−5x
fx−5x=−3
Step 2: Factor out variable x.
x(f−5)=−3
Step 3: Divide both sides by f-5.
x(f−5)
f−5
=
−3
f−5
x=
−3
f−5
Answer:
x=
−3
f−5

Answer:
the profit will be $172
Step-by-step explanation:
The function given is:
p(x) = 2(x-9)^2 + 100
Where x is the price of the each shirt.
if each shirt is sold for $15, hen x = 15.
the profit will be:
p(15) = 2(15-9)^2 + 100
p(15) = 2(6)^2 + 100
p(15) = 2(36) + 100
p(15) = 72 + 100
p(15) = 172
So, the profit will be $172
Integrating 
gives
Notice that 
forces all terms in the sum to be 0, so that
and hence
making the first option correct.
