It is if my calculations are correct 1250 least thats what my calculator said..
Answer:
y=1/2x-1
Step-by-step explanation:
1) <span>-3, 6, -9, 12...
f(2) = -2*6 - (-3) = -9
f(3) = -2*-9 - (6) = 12
2) </span><span>2) Choose the slope-intercept equation of the line that passes through the point (-2, 2) and is parallel to y = 4x + 7.
Slope equals 4, since it's parallel. Substituting...
2 = 4*-2 + b Add 8 to both sides
10 = b
y= 4x + 10
3)Question is poorly transcribed, but assuming the points are (10, 60) and (16, 96):
Average rate of change = (96-60) / (16-10) = 36 / 6 = 6m/s.
4) A slope of zero means that y does not change with x. This means y is the same for any x value, so y is a horizontal line.
The third graph, the one where y= -6, is the correct answer.

Answer:
I don't get it and what grade level is this
Given:
A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.
To find:
The surface area of the pyramid to the nearest whole number.
Solution:
A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.
Area of a square is
So, area of square base is 100 sq. in.
Area of a triangle is
So, area of each triangular surface is 20 sq. in.
Now, the total surface area of the pyramid is
Total area = Area of square base + Area of 4 congruent triangles.
Therefore, the area of the pyramid is 180 sq. in.
