Answer:
The square-shaped slice can be made from a slice parallel to the base of a right rectangular prism, cube, and right rectangular pyramid with a square base. The triangle-shaped slice and isosceles trapezoid-shaped slice can be made with a slice made perpendicular to the base of a right rectangular pyramid.
Answer:
<em>y = 8.25x</em>
Step-by-step explanation:
<u>Linear Modeling</u>
Some events can be modeled as linear functions. If a situation comes where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.
The linear function can be expressed in the slope-intercept format:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

Let's use linear modeling to represent Steven's earnings he makes babysitting. Call y the money he charges by x hours of work.
We know he charges y1=$33 for x1=4 hours, and y2=$57.75 for x2=7 hours. The ordered pairs are (4,33) and ( 7, 57.75)
Computing the equation of the line we have:

Operating:



y = 8.25x
There is a proportional relationship.
Here we see that the number 27 is closer to 30 than 20. Here we cannot see whether 25 is closer to 20 or to 30. If the digit following the rounding place is 0, 1, 2, 3, or 4, we round down. If the digit following the roundingplace is 5, 6, 7, 8, or 9, we round up.
Answer:
y = 2x -- Multiplicative: y is 2 times x.
y = x + 2 -- Additive: y is 2 more than x.
