Answer: 15
Step-by-step explanation: I used the pythagorean theorem. X is a, 8 is b, and 17 is c. The squares of a and b added together are c. So I got 15.
Y = kx
Plug in what we know:
5 = k(8)
5 = 8k
Divide 8 to both sides:
k = 0.625
Plug this back into the equation along with y = 15:
y = kx
15 = 0.625x
Divide 0.625 to both sides:
x = 24
Answer:
the answer is c 28 dived by 100 = 0.28
Step-by-step explanation:
I believe the answers you want are 0, 1, 2, 5
We first need to know the mathematical expression that f(x) represents following the algorithm given.
Step 1: Start with a number and add 2
Let the number = x
Adding 2 to the number gives x + 2
Step 2: Take the result and multiply by 3
This will give 3(x + 2)
Step 3: Take the result and subtract 10
This will give 3(x+2) - 10
Step 4: Square the final number:
The result will be [3(x+2) - 10]²
Therefore, f(x) = [3(x+2) - 10]²
To get the inverse of f(x), follow this algorithm
Step 1: Start with a number and take the square root
Let the number be x
Square root of x = √x
Step 2: Take the result and add 10
This will give √x + 10
Step 3: Take the result and divide by 3
This will give (√x + 10)/3
Step 4: Take the result and subtract 2
