Cos = adjacent over hypotenuse
cos33 = b/170
170cos33 = b
b = 142.574 inches
Answer: 60 units²
Step-by-step explanation:
The total area of the rectangle is equal:
(4+4)*(9+3)=
8*12=
96 units²
The area of the unpainted part of the rectangle is equal:
4*9=
36 units²
The area of the shaded region is equal:
96-36=
60 units²
4+4x+4x=20
4+8x=20
4=12x
3=x
15 is half of 30...right. so what is half of 6...Thats your answer. because in #10 y=5x. do a similar thing with number 12. accept with looking at t instead of x for your given value
Answer:
<h2>
h(x) = 4x+48</h2>
Step-by-step explanation:
Given the function f(x) = 1/4x -12. To get the inverse of the function, first we will let y = f(x) to have y = 1/4x - 12.
Then we will make x the subject of the formula as shown:
y = 1/4x - 12
adding 12 to both sides we have;
y + 12= 1/4x - 12 + 12
y + 12 = 1/4x
Multiplying both sides by 4 we have;
4(y+12) = x
x = 4y + 48
Substituting y for x
y = 4x+48
f^-1(x) = 4x+48
h(x) = 4x+48
Thee final expression will give the inverse of the function
