Answer:
see below
Step-by-step explanation:
We assume you want the graph of ...
A graphing calculator or spreadsheet is useful for this.
__
You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.
r at 0° = 8
r at 30° ≈ 7.05
r at 45° ≈ 6.19
r at 60° ≈ 5.33
r at 90° = 4
r at 120° = 3.2
r at 135° ≈ 2.96
r at 150° ≈ 2.79
r at 180° ≈ 2.67
Answer:
135 ft^2.
Step-by-step explanation:
The total surface area
= 2 * area of the triangular sides + area of the 3 rectangular sides
= 2 * 1/2 * 2.5*6 + 8*6 + 8*6.5 + 8*2.5
= 135 ft^2.
We know that
the Volume of a prism=a*b*c
a----> tall--------> 8 1/2 in=8.5 in
b-----> wide-----> 7 in
c-----> <span>thick-----> 2 1/2 in=2.5 in
therefore
V=8.5*7*2.5=148.75 in</span>³------------equal a 148 3/4 in³
the answer is the option <span>c 148 3/4 in³</span>
Is it 3g? idk sorry i need points
The vocabulary terms have been matched to the correct definitions as follows;
- Direct variation: describes variation between proportional relationships
- Slope: a ratio describing vertical change to horizontal change of a linear relationship on a coordinate grid
- Rate of change: a number, k, that represents the unit rate used in a direct variation equation y = kx for comparing proportional relationships between two variables x and y found by using division
- Unit rate: a speed or rate of change where the denominator (or second quantity measured) in the ratio is 1
- Constant of proportionality: the ratio of vertical change to horizontal change rate of change
<h3>What are Mathematical Terms?</h3>
- Mathematical terms refer to phrases and words that define certain arithmetic standards.
- The above are the definitions of the mathematical terms. Direct variation, for instance, expresses the relationship between two variables, x, and y.
- The slope is often used after graphing and indicates the relationship of change between the vertical and horizontal axes.
