Answer:
Step-by-step explanation:
Angles in a triangle add up to 180
An acute angle is any angle smaller than 90
Since it is a right angle triangle, one of the angles is a right angle and therefore 90
So 180 - 90 - 25 = 65
Use interval notation to represent the set of numbers: 1 ≤ x < 20 or x > 30

Answer:
SA = 153.9m^2
Step-by-step explanation:
SA = 4
r = 3.5
SA = 4
SA = 4(12.25)
SA = 49
SA = 153.9m^2
Replace f(x) with y
switch x and y
solve for y
replace y with f^-1
so
y=7x+2
x=7y+2
x-2=7y
(x-2)/7=y
f^-1=(x-2)/7
inverse is
