1. Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number
of shirts sold. After selling a certain number of
shirts, Benito uses some earnings to buy more
materials and then increases the price of the
shirts. Which of the following is true?
A )Benito increases the price after selling 50 shirts.
B)The y-intercept represents the cost of one
T-shirt.
C)The x-intercept represents the shirts he has to sell before making a profit.
D)The domain of the function is {x|x is a real number greater than or equal to 0).

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down
