Answer:
Find the equation of the line perpendicular to x = 0 that passes through (-3,1)
Step-by-step explanation:
Using the equation, y - y1 = m(x - x1)
Since x = 0, the gradient, m = 0
Hence, y - 1 = 0
∴ y = 1
Answer:
The hiker's elevation after 145 minutes will be 1958 meters.
Step-by-step explanation:
The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).
Now, we have to predict the hiker's elevation after 145 minutes.
So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
Answer:
yes 5 is right
Step-by-step explanation:
Answer:
2.25π in²
Step-by-step explanation:
The area can be found from the circumference using the formula ...
A = C²/(4π)
Putting in the given dimension, you have ...
A = (3π)²/(4π) = (9/4)π = 2.25 π . . . . in²
Answer:
y = -3x + 7
Step-by-step explanation:
when they are parallel, they always have the same slope.
