Answer:
z = 5
Step-by-step explanation:
Here, I am using the 30 60 90 right triangle rule
7+3 = 2x
z = 5
x = 5√3
5x+2y=20 when x=3/10 is:
5(3/10)+2y=20
15/10+2y=20
1.5+2y=20
2y=18.5
y=9.25
Answer:
The required equation 
C should be correct.
Step-by-step explanation:
Given: Julissa is running a 10-kilometer race at a constant pace.
After running for 18 minutes, she completes 2 kilometers.
First point: (18,2)
After running for 54 minutes, she completes 6 kilometers.
Second Point: (54,6)
We need to write an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable
Using two point formula to find the equation of line
Formula:
Required Equation:
Hence, The required equation
Next time you should write the correct form of equation
because it affects greatly the answer. I believe the correct form would be:
f (x) = 2 * x^2 + 1
where the second 2 is a power of x
The average rate of change is also defined as the slope
of the equation. Therefore:
average rate of change = slope
Where slope is:
m = (y2 – y1) / (x2 – x1) = [f (0) – f (-1)] / (x2 – x1)
Calculating for f (0): x2 = 0
f (0) = 2 * 0^2 + 1 = 1
Calculating for f (-1): x1 = -1
f (-1) = 2 * (-1)^2 + 1 = 3
Substituting the known values to the slope equation:
average rate of change = (1 – 3) / (0 – 1)
average rate of change = -2 / -1
average rate of change = 2
