Answer:
115.5
Step-by-step explanation:
the car is traveling at precisely 52.5 miles an hour
Answer:
See below
Step-by-step explanation:
A) Recall that a turning point is where the function changes from increasing to decreasing or vice versa. Since the graph of the function is a parabola, it only has 1 turning point, which is the vertex, or (1,-4). Therefore, the coordinates of the turning point are (1,-4).
B) The roots of the equation can be found by determining where the graph intercepts the x-axis (aka. x-intercepts). In this case, these are points (-1,0) and (3,0).
Answer:
thank you
Step-by-step explanation:
................
Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
Given that,
We have to find are we extrapolating or interpolating when we use a least-squares line to forecast y values for x values outside the range of x values seen in the data.
Option A) We are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
<h3>What is extrapolation?</h3>
Extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable.
Therefore, Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
