Answer:
Step-by-step explanation:
Remark
This is a right angle triangle.
Proof
a^2 + b^2 = c^2
a = 3
b = 4
c = 5
3^2 + 4^2 = 5^2
9 + 16 = ? 25
25 = 25
Area
The 2 smaller legs are perpendicular to each other.
Area = 1/2 a * b
Area = 1/2 * 3 * 4
Area = 6
Answer:
The diameter is 22cm

I dont know if thats what the question is asking but here
Answer I think and you can't get help on a quiz
Answer: 1st, 3rd, and 4th functions
Step-by-step explanation:
Assuming k(x)=9x^2, all the other functions have inverses because they are linear, meaning they must be one-to-one.
Y= 0.8x - 17
x= (y+17)/0.8
substituting y= 47 in the equation
x= (47+17)/0.8
x= 64/0.8
x=80
