Answer:
The answer is 53 or Square Root (sqrt) of 2809
Step-by-step explanation:
a^2+b^2=c^2
28^2+45^2=c^2
784+2025=c^2
c^2=sqrt 2809
c = 53
Answer:
the slope would be equal to -x or -1
Step-by-step explanation:
First rewrite the equation in correct slope intercept form. Subtract x from both sides and then divide both sides by a negative sign.
x - y = 8
-x -x
y= x +8
A perpendicular slope is the inverse of the original slope. If the original slope is 2 then the perpendicular slope would be -1/2. In this problem the original slope is 1. The inverse of 1 is -1
Solve:
We need to isolate k, so multiply both sides by the denominator, which is 64. When we do that, the fraction will cancel and we get:
If you want to check, plug in your answer to the original equation and see if it is true:
This statement is true, so .
Given Information:
Population size = n = 300
standard deviation = σ = 15
confidence level = 99%
Required Information:
Margin of error = ?
Step-by-step explanation:
The margin of error is a measure of the effectiveness of your survey.
Margin of error = z*(σ/√n)
z-score corresponding to 99% confidence level = 2.58
Margin of error = ±2.58*(15/√300)
Margin of error = ±2.58*(0.866)
Margin of error = ±2.23
Hence the correct option is C ±2.23
For this case we have the following function:
y = ^ 3√x
Applying the following transformation we have:
Expansions and horizontal compressions
The graph of y = f (bx):
If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b.
y = ^ 3√0.5x
Answer:
A.It is horizontally stretched by a factor of 1 / 0.5
