Step-by-step explanation:
I have used substitution method here to find the value of x and y.
Answer:
x = 10.2
Step-by-step explanation:
To find x, use Cosine
Cosine = 
⇒ Cosine 22 = 
Cosine of 22 is 0.93
⇒ 0.93 = 
Multiply 11 on both sides:
⇒ 0.93 x 11 =
x 11
⇒ 10.23
Round to the nearest tenth:
10.23 ⇒ 10.2
x = 10.2
Answer:
f(-3) = -16
Step-by-step explanation:
Given piecewise function is,
f(x) = 5x - 1 If x < -2
x + 3 If x ≥ -2
We have to find the value of he function when x = -3
Since x = -3 is less than x = -2,
Piece of the function to be considered,
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -16
He uses 4/6 of the yard or 2 feet depending on what you are looking for
5/10 if you want it simplified it would be 1/2, because 1,3,5,7,9 are prime numbers so there are 5 of them out of the 10 numbers.
