Answer:
Slope
Step-by-step explanation:
Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
Answer:
and Mathematics this soap or gradient of a line is a number that describes both the direction and the steepness of the line assault with a greater absolute vinyl indicates a steeper line the direction of a line is either increasing decreasing or horizontal or vertical

The cost, C. of producing coolers, x, is modeled by the equation C = 0.005x2 - 0.3x + 17. How many coolers are
produced when the cost is $19. Round your answers to the nearest whole number
All work must be clearly shown, step by step, to receive full credit. Separate your work. Each new statement or
equation, must be on a new line.
Answer:
66 coolers
Step-by-step explanation:
C = 0.005x² - 0.3x + 17
When C = $19
19 = 0.005x² - 0.3x + 17
19 - 17 = 0.005x² - 0.3x
2 = 0.005x² - 0.3x
0.005x² - 0.3x - 2 = 0
x = -b ± √b² - 4ac / 2a
= -(-0.3) ± √-0.3² - 4*0.005*-2 / 2*0.005
= 0.3 ± √ 0.09 - (-0.04) / 0.01
= 0.3 ± √ 0.09 + 0.04 / 0.01
= 0.3 ± √ 0.13 / 0.01
= 0.3/0.01 ± √0.13/0.01
= 30 ± 0.36/0.01
x = 30 ± 36
x = 30 + 36 or 30 - 36
x = 66 or -6
Number of coolers can not be negative
Therefore, number of coolers produced when the cost is $19
is 66 coolers

Sarawong invests $4,537 in a retirement account with a fixed annual interest rate of 4.55% compounded quarterly. What will the account balance be after 17 years?
Answer:
$8,046.37
Step-by-step explanation:
4,537*0.0455= 206.4335
206.4335*17=3509.3695
4537+3509.3695=8046.3695
8046.3695 rounded = $8,046.37
A city has 17391 registered Democrats and 20553 registered
Republicans. An organization wishes to survey equal proportions of
each group.
The council decides to survey 13 Republicans
How many Democrats should they survey? Democrats
Answer: The council should survey 11 Democrats.
Step-by-step explanation:
A proportional relationship is written as:
y = k*x
Where k is the constant of proportionality. y is the number of surveyed members, and x is the total number of registered members.
If we use the same proportion for each case, then we will use the same value of k.
We know that there are 20553 registered Republicans, and the council decides to survey 13 of them, then we will have the relation:
13 = k*20553
Now we can solve this for k:
13/20553 = k
Then the proportional relationship will be:
y = (13/20553)*x
The number of democrats they should survey can be found if we replace x by the number of registered Democrats, then we use x = 17391
this leads to:
y = (13/20553)*17391 = 11
The company should survey 11 Democrats.

A 4-foot-long sandwich is cut into servings that are each foot long. How many
servings will there be after the sandwich is cut?
3
12
Answer: 4
Step-by-step explanation:
If the foot-long sandwhich is 4 feet long, and is cut into parts that are each 1 foot long, then we need to divide 4 by 1.
4 ÷ 1 = 4, so there will be 4 servings after the sandwich is cut.

Simplify the expression using the distributive property:
5 (2x – 3y + 4)
Apply the distributive property. 5 (2x) +5 (−3y) + 5 ⋅ 4
Multiply 2 by 5
10x + 5 ( − 3y ) + 5 ⋅ 4
Multiply −3 by 5 10x − 15y + 5 ⋅ 4
Multiply 5 by 4
Answer: 10x −15y + 20
Tip: The sign "⋅" means multiply
what equation contains the given point ( -3,5)
Answer:
y = x + 8
Step-by-step explanation:
Answer:
To determine if a point is on a line you can simply subsitute the x and y coordinates into the equation. Another way to solve the problem would be to graph the line and see if it falls on the line. Plugging in will give which is a true statement, so it is on the line.

A car moving on a highway covers the first 400.0 m in 18.0s and then covers the next 250.0 m in 24.0 s.
What is the average speed of the car?
Answer: 15.48 m/s
Step-by-step explanation:
The following information can be gotten from the question:
Total distance covered by the car will be:
= 400m + 250m
= 650m
Total time taken = 18.0s + 24.0s = 42s
Average speed = Distance/Time
= 650/42
= 15.48 m/s

9. A triangle has an area of 36 yd2 and a base of 3 yd, what is the height of the triangle?
Answer:
24yards
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 24 \ yards}}[/tex]
Step-by-step explanation:
The formula for a triangle's area is:
[tex]a= \frac{1}{2} bh[/tex]
We know the area is 36 square yards and the base is 3 yards.
[tex]a= 36 \ yd^2 \\b= 3 \ yd[/tex]
Substitute the values into the formula.
[tex]36 \ yd^2 = \frac{1}{2} (3 \ yd )h[/tex]
Divide by 1/2 or multiply both sides by 2.
[tex]2 * 36 \ yd^2 = \frac{1}{2} (3 \ yd )h *2[/tex]
[tex]72 \ yd^2= (3 \ yd)h[/tex]
We are trying to solve for the height, so we must isolate that variable. h is being multiplied by 3. The inverse of multiplication is division, so we must divide both sides by 3 yd.
[tex]\frac {72 \ yd^2}{3 \ yd}= \frac{(3 yd) h}{3 \ yd}[/tex]
[tex]24 \ yd =h[/tex]
The height of the triangle is 24 yards.
