The only way you can find x here is to use a trig ratio. We have the reference angle of 75, CA is 10 which is the side adjacent to the reference angle, and we are looking for the hypotenuse. The ratio that relates the side adjacent to a reference angle to the hypotenuse is cosine. Therefore, $cos(75)= \frac{10}{x}$ . Solving for x we get $x= \frac{10}{cos(75)}$ . Do that on your calculator and find that the hypotenuse is 38.6 m long, last choice from above.

A group of artists is selling small prints to raise money for charity. They sell p prints, and make a profit of f(p) on the sale

MrRissso [65]

Answer:

Statement A is true.

Step-by-step explanation:

A. If the group sells 15 prints, they will lose $85.

B. If the group sells 12 prints, they will lose $204.

C. If the group sells 35 prints, they will make $935.

D. If the group sells 28 prints, they will lose $136.

f(p) = 17p - 340

p = prints

f(p) = profit

Let's check the statements to see which one is true.

A. 17.15 - 340 = - 85 OK!

B. 17.12 - 340 = -136 (false, they will lose $136)

C. 17.35 - 340 = 255 (false, they will make $255)

D. 17.28 - 340 = 136 (false, they will make $136)

Answer:

Slope = -1/5

Step-by-step explanation:

(-5, -2)(5, -4)

Slope: $\frac{y^{2}-y^{1} }{x^{2}- x^{1} } = \frac{-4-(-2)}{5-(-5)} =\frac{-4+2}{5+5} =\frac{-2}{10}=-\frac{1}{5}$
