In the mail, you receive a coupon for $5 off for a pair of jeans, which is represented by the function j(x)=x−5. When you arrive

at the store, you find that all jeans are 25% off, which is represented by the function s(x)=0.75x. Which of the functions below represents how much you would pay for a pair of jeans, C(x)=s(j(x)) , if you use the coupon first followed by applying the discount from the store? (Do not consider tax.)
A .C(x)=0.75x−5
B .C(x)=0.75(x−5)
C .C(x)=0.75x−x−5
D .C(x)=x−5−0.75

Answer: B

Step-by-step explanation: The function C(x) = s(j(x)) shows you how to solve it.

First in the parenthesis j(x) so you have to substitute since they told you

j(x) = x-5

Next s(x-5) and s(x-5) = 0.75(x-5) through substitution

Answer:

∠ A ≈ 44.42°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos A = \frac{adjacent}{hypotenuse}  = \frac{AC}{AB} = \frac{5}{7} , then

∠ A = cos^{-1} (\frac{5}{7} ) ≈ 44.42° ( to the nearest hundredth )

When using pi, do you use 3.14 or 3.141592653?
sergey [27]

Answer:

You would usually use 3.14

Step-by-step explanation:

It kind of depends on where you are using it. In an equation, pi would be used as 3.14 and the answer would be approximated. To write it anywhere else (I dont know where else you would though), you would do the pi symbol. I hope this helps.
