i got 100% on this quiz
The solutions to the equation x³ = 36, x² = 42, x³ = 55 are:
x = ∛36
x = √42
x = ∛55
Option B, D, and F are the correct answers
Given,
Which of these is a solution to the equation x³ = 36, x² = 42, x³ = 55
Select three that apply.
A. x = √36
B. x = √42
C. = √55
D. = ∛36
E. = ∛42
F. = ∛55
How do we write square root and cube root?- Square root of a is written as √a.
- Cube root of a is written as ∛a.
We have,
- x³ = 36
Cube root on both sides
∛x³ = ∛36
x = ∛36
- x² = 42
Squaring on both sides
√x² = √42
x = √42
- x³ = 55
Cube root on both sides
∛x³ = ∛55
x = ∛55
We see that,
x = ∛36
x = √42
x = ∛55
Thus the solutions to the equation x³ = 36, x² = 42, x³ = 55 are:
x = ∛36
x = √42
x = ∛55

which two points lie on a line with a slope closest to zero ?
Answer:
Point N and point K
Step-by-step explanation:
The steeper a line is in the graph, the greater the value of the slope of the line would be, and also, the farther it would be from 0. On the other hand, the more gentle and less sloppy a line is, the smaller the value of the slope is, and also, the closer it is to 0.
From the graph given, there are possible set of points in a line that have a gentle line slope.
The first is, points N and K. The slope of this line is ⅑.
The second is, points P and L. The slope of this line is ⅙.
From the two above lines, the one with a slope closest to 0 is the line that runs through points N and K. ⅑ is closer to 0 than ⅙.

The three angles of a triangle are in the ratio 5:4:1. Find all the angles of the triangle.
Answer:
Step-by-step explanation:
let the first angle be 5x
second be 4x
and third be 1x
as we know that by adding all the sides of triangle we get 180°
therefore ,
5x+4x+1x=180°
10x=180°
hence ,
x=18°
first angle - 18*5 = 90°
second angle - 18*4=72°
third angle - 18°
HOPE THIS HELPS YOU !!!
Answer:
18°, 72°, 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the parts of the ratio, 5 + 4 + 1 = 10 parts
divide to find the value of one part of the ratio
180° ÷ 10 = 18° ← value of 1 part of the ratio , thus
5 parts = 5 × 18° = 90°
4 parts = 4 × 18° = 72°
Thus the angles of the triangle are 18°, 72° and 90°
Michael Fenton sells plumbing supplies to contractors. He earns 3% commission on the first $15,000
in sales, 5% on the next $15,000, and 8% on sales over $30,000. Last month he sold $52,000 worth
of plumbing supplies. What was his total commission?
Answer:
His total commission was: $2,960
Step-by-step explanation:
The commissions that Michael Fenton earns by selling plumbing supplies to contractors has three levels:
On the first $15,000 in sales, he earns 3%
On the next $15,000 in sales, he earns 5%
Over $30,000 in sales, he earns 8%.
Last month he sold $52,000 worth of plumbing supplies. His commissions will be calculated according to the levels reached:
The first $15,000 gave him 3%*15,000=0.03*15,000=$450
From the $52,000 sales, there remains $52,000 - $15,000 = $37,000 for the next levels.
The next $15,000 gave him 5%*15,000=0.05*15,000=$750
Now $37,000 - $15,000 = $22,000 remain for the last level.
Michael earned 8% of $22,000 = 0.08*22,000 = $1,760
His total commission was: $450 + $750 + $1,760 = $2,960

Parallelograms PQRS and QRTU are standing on
the same base QR and between the same parallel
lines PT and QR. Prove that the area of
parallelograms PQRS and QRTU are equal.
Parallelograms PQRS and QRTU have the same base QR and height. it proves that areas are equal as base × height remains constant.
To prove that the area of parallelograms PQRS and QRTU are equal,
Use the concept that parallelograms with the same base and between the same parallel lines have equal areas.
Parallelograms PQRS and QRTU
Same base QR
Between the same parallel lines PT and QR
Proof,
Draw a diagram with parallelograms PQRS and QRTU sharing the common base QR and being situated between parallel lines PT and QR.
Since PQRS and QRTU share the same base QR and are between the same parallel lines PT and QR, their heights (perpendicular distances from base QR) are equal.
Let's call this height 'h'.
The area of a parallelogram is given by the formula:
Area = base × height.
For PQRS, its area would be: Area of PQRS = QR × h.
For QRTU, its area would be: Area of QRTU = QR × h.
Since both parallelograms have the same base 'QR' and the same height 'h', their areas are equal.
Therefore, it is proved that the area of parallelograms PQRS and QRTU are equal.

increasing or decreasing?
slope?
y and x intercept?
other points the line goes through?
equation if the line?
Answer:
slope = 1/2
The x-intercept is (8, 0). The y-intercept is (-4, 0).
(2, -3), (4, -2), (6, -1)
y = (1/2)x - 4
Step-by-step explanation:
1)
slope = rise/run
Start at (0, -4) and go to (2, -3).
Start at (0, -4) and go 1 unit up. That is a rise of 1.
Now go 2 units right to arrive at (2, 3). That is a run of 2.
slope = rise/run = 1/2
2)
The line crosses the x-axis at (8, 0).
The x-intercept is (8, 0).
The line crosses the y-axis at (-4, 0).
The y-intercept is (-4, 0).
3)
Here are some points: (2, -3), (4, -2), (6, -1)
4)
y = mx + b
y = (1/2)x - 4
Answer:
Below in bold.
Step-by-step explanation:
The line is rising to the right so it has an increasing slope.
The slope of the line is 4/8 = 1/2.
Reading from the graph the x intercept is (8, 0).
The y-intercept is (0, -4).
The line passes through the points (2, -3) and (6, -1).
The equation of the line is:
y = (1/2)x - 4.

Answer:
C ( x = 2 (multiplicity of 2), x = -2, x = -4)
A ( x = 5 (crosses), x = -3 (touches))
Step-by-step explanation:
Here are a couple of rules that helped me come to these answers.
1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.
2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.
3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.
A scientist studied the migration patterns of two types of whales. The humpback whale traveled 2,000 miles in 25 days. The gray whale traveled 2,250 miles in 30 days. Assuming the humpback whale travels the same distance each day, what is the unit rate for the humpback whale in miles per day?
Answer:
it is 80 miles
Step-by-step explanation:
2000 divided by 25 is 80 therefore you multiply 80 x 30

what is 9x2y-3 if x = 5 and y = 3.
Answer:
267
Step-by-step explanation:
use the triangle inequality theorem
Answer:
Step-by-step explanation:
B) 9<x<5
X has to be more than 9. 9+8=17, which would be a straight line.
X has to be less than 25. 17+8=25, which would be a straight line.
Answer:
9 < x < 25
Step-by-step explanation:
The length of a side of a triangle must be greater than the difference between the lengths of the other sides and less than the sum of the lengths of other sides.
x must be greater than the difference between 17 and 8.
17 - 8 = 9
x > 9
x must be less than the sum of 17 and 8.
x < 17 + 8
x < 25
When you put the two inequalities above together, you get:
9 < x < 25
