Answer:
It is approximately ~6.70820393
Step-by-step explanation:
If we just have

that's an amplitude of 1 and a period of 
Let's modify this step by step.
Amplitude of 4. Four times the amplitude means a factor of 4 on the outside.

Period of π. Double the period means a factor of 2 on the inside.

Horizontal shift of π/2 to the left. To the left means adding a positive number to x. The question appear ambiguous. It's not clear to me if we add to x or 2x; let's make it

Vertical shift of 3:


Depending on the interpretation of the phase shift, that pi may be a pi/2.
Answer: 
Answer:
The y-intercept is -4
Step-by-step explanation:
You have your x intercept, which is 4 and your y is -4. Hope this helps :)
Answer:
8
Step-by-step explanation:
4(5) - 6 = 14
14 is not larger than 22, so 5 is not the solution.
4(8) - 6 = 26
26 is larger than 22, so 8 is the solution
Well the first thing you need to know is that there are 3 feet in 1 yard. Therefore 3 yards is equal to 9 feet of fabric. The next thing you need to know is how many costumes she can make with 1 foot of fabric which is just 8 divided by 4 so your answer is 2. Then you just multiply 9 and 2 to get 18 costumes. Therefore the designer can make 18 costumes with 3 yards of fabric if she goes at the same rate.
