Name the slope and one point that is on the line
represented by the equation: x = -2
A) m = undefined and point (-2,5)
B) m = 0 and point (-2,4)
C) m = undefined and point (5,-2)
D) = zero and point (5,0)
Answer: Choice A
m = undefined
point (-2,5)
==================================================
Explanation:
The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)
Another point on this line is (-2,5) since this also has x coordinate -2.
------------------
All vertical lines have undefined slope.
Let's pick two points such as (-2,0) and (-2,1) and find the slope through them
m = (y2-y1)/(x2-x1)
m = (1-0)/(-2-(-2))
m = (1-0)/(-2+2)
m = 1/0
m = undefined, since we cannot divide by zero.

each morning max walks to school. at 8:20, he passes a stoplight that is 2 blocks from home. He reaches the town library at 8:24. At this point, he is 3 blocks from school and halfway there. If Max walks at the same pace all the way to school, at what time does he arrive at school?
Answer:
8:36
Step-by-step explanation:
If he is at his halfway point at 8:24 and it only took him 4 minutes to get one block in than it would take him 12 minutes to get 3 blocks in and if you add 12 more minutes to the time that he's at right now than he would arrive at 8:36.

Find the percent of increase from 8 to 10 feet
Answer:
25%
Step-by-step explanation:
[tex]percentage \: increase \\= \frac{10 - 8}{8} \times 100 \\ \\ = \frac{2}{8} \times 100 \\ \\ = \frac{1}{4} \times 100 \\ \\ = 25 \%[/tex]
The increase in height from 8 to 10 feet is 25%. To calculate a percentage, divide the value by the total value and multiply the result by 100.
How to calculate percentage?To calculate a percentage, divide the value by the total value and multiply the result by 100. (value/total value)100% is the formula for calculating percentage. Divide the number you want to convert to a percentage by the total. In this case, divide 2 by 5. 2 divided by 5 equals 0.4. Then, multiply 0.4 by 100 to get 40, or 40%.Divide one number by the other and multiply the result by 100 to find the percentage of a number between two numbers. To calculate the percentage, divide the value by the total value and multiply the result by 100.Therefore,
percentage increase
= (10 - 8) / 8 × 100
= 2/8 × 100
= 1/4 × 100
= 25%
Hence, The increase in height from 8 to 10 feet is 25%.

Suppose our retirement account pays 9% apr compounded monthly; what size nest egg do we need in order to retire with 25 years that yields to $5,000 per month? Show all work
Answer:
$595,808.11
Step-by-step explanation:
We assume the retirement account is intended to pay out $5000 per month for 25 years. The amortization formula can be used to find the required amount. The monthly payment A based on principal P with interest at annual rate r for t years satisfies the relation ...
A = P(r/12)/(1 -(1 +r/12)^(-rt))
P = A(12/r)(1 -(1 +r/12)^(-rt))
P = 5000(12/0.09)(1 -(1 +.09/12)^-300)
P = $595,808.11
The required nest egg is $595,808.11.

What is the center of the circle represented by the equation x2 + y2 - 4x + 2y + 1 = 0?
Answer:(2,-1)
Step-by-step explanation:
The required center of the given circle is given as (2, -1).
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on coordinate plane and r is the radius of the circle.
Here,
The standard form of the equation of the circle s is given as,
x² + y² -2hx -2ky + c = 0
Given the equation of the circle is
x² + y² - 4x + 2y + 1 = 0
Comparing the equations,
-2h = -4
h = 2
-2k = 2
k = -1
Thus, the required center of the given circle is given as (2, -1).

Classify the data of the heights of ladders produced by a tool company.
Complete Question:
1. Classify the data of the heights of ladders produced by a tool company.
Group of answer choices :
Statistics
Qualitative
Classical
Quantitative
Answer:
The data of the heights of ladders produced by a tool company is:
Quantitative
Step-by-step explanation:
The heights of ladders are stated in numbers. Quantitative data give information about quantities or numbers. They can be measured with certainty. They are not like qualitative data which are descriptive and cannot be easily measured unless classified in some ways. Quantitative measurements associate measurement units to data, e.g. meters and feet. For example, the heights of persons, buildings, or things like ladders can be measured quantitatively in meters and feet. Another feature of quantitative data is that arithmetic operations can be performed on the data.

A company estimates that 0.7% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $350. If they offer a 2 year extended warranty for $48, what is the company's expected value of each warranty sold?
Answer:
$44.90
Step-by-step explanation:
The resulting value for the company of replacing a failed product is given by the price of the warranty minus the cost of replacement:
F = $47-$300=-$253
This event has a 0.7% chance of happening.
The resulting value for selling extended warranty to a product that does not fail is given by the price of the warranty:
W = $47
This event has a 99.3% chance of happening.
The expected value is:
EV = $44 * 0.993 + ($47-$300) *0.007
EV = $44.90
The expected value for each warranty sold is $44.90.
