Predicting y outside range of x is called
This is referred to as extrapolation.
Take for instance, the range of x is: 1 - 9
You have extrapolated when, 10 is assumed to be the value of x and this value is entered in an equation to predict y.
Answer:
300
Step-by-step explanation:
Since it says first rounding both numbers to the tenth place you will round 12 and 27
12 = 10
27 = 30
10 times 30 = 300
Hope this helps dude
Answer:
It touches the x-axis once, but does not intersect it
Step-by-step explanation:
I'm assuming it's supposed to be y = x² + 10x + 25. This equation does not intersect the x-axis, but it does touch the x-axis.
Solve the equation for x...
0 = x² + 10x + 25
factor...
0 = (x + 5)(x + 5)
The solution repeats, this means that the function touches the x-axis and then bounces off, but doesn't intersect it. Intersect meant to cross the line, here it just touches it.

To find the area that is the closest, use the formula for finding the area of a circle.
A = pi x r^2
3.14 x 25^2
A = 1962.5 square feet
This is closest to answer choice D.
