Determine the slope and y-intercept of a line that passes through the points (-2, 12) and (4, -15).
Answers
Step-by-step explanation:
y²-y¹/x²-x¹
(-15)-(12)/4-(-2)
-3/6
=-0.5
y=mx+b
12=-0.5(-2)+b
12=1+b
12-1=b
11=b
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6
The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a line is y = mx + c.
The slope can be calculated.
Slope = (d - b) / )(c - a)
Where (a, b) and (c, d) are the two points on the line.
The line passes through (-2, 12) and (4, -15)
This means,
Slope = (-15 - 12) / (4 + 2) = -27 / 6
m = -27/6
The line passes through the point (-2, 12).
12 = -27/6 x -2 + c
12 = 9 + c
c = 12 - 9
c = 3
Thus,
The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6
The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3

What is 1872.072 rounded to the nearest hundredth?
Answers
Answer:
1872.07
Step-by-step explanation:
The hundredth place is the second digit after the decimal (.).
The 1872 will always be the same since it is hundredth and not something else like tens or hundreds.
1872....
So since the hundredth place is the second digit after the decimal, you can find that the second digit is 7.
4 or less don't round up, 5 or more round up
Since the next digit is 2, it is 4 or less, so don't round up, so you cut off the 2, hence the 1872.07
EDIT: Aha I need my sense of humor back... brb
Answer: 1872.07
Step-by-step explanation: 7 is in hundredth place so we take the number that comes after it and round up or down since it 2 we round down to 0 then add it to 7.
7+0= 7 so 7 stays the same (because numbers from 1-4 round to zero and numbers from 5/9 round to 1)

Answers
Answer:
h = 5.42
r = 5.42
Step-by-step explanation:
Find h with respect to r:
V = πr²h = 500
h = 500/πr²
Plug this into the surface area equation:
SA = πr² + 2πrh
= πr² + 2πr(500/πr²)
= πr² + 1000/r
Differentiate and set to 0, solve for r:
dSA/dr = 2πr - 1000/r² = 0
2πr = 1000/r²
r³ = 500/π
r = (500/π)^1/3
≈ 5.42 cm
find h:
h = 500/πr²
= 500/[π(5.42)²]
= 5.42cm

The table shows a relationship between x and y. What is the constant of proportionality, k, which relates the variable y to the variable x?
Answers
Answer:
F. [tex] \frac{3}{4} [/tex]
Step-by-step explanation:
Constant of proportionality, k, = [tex] \frac{y}{x} [/tex]
The ratio of each given of values on the table will give you the same value, which represents k.
Thus, using the pair, (2, 1.5), k can be calculated as follows:
[tex] k = \frac{y}{x} = \frac{1.5}{2} [/tex]
Multiply the numerator band denominator by 10 to eliminate the decimal point.
[tex] = \frac{1.5*10}{2*10} = \frac{15}{20} [/tex]
Simplify
[tex] k = \frac{3}{4} [/tex]

Arithmetic sequence; common difference is −144
c
Geometric sequence; common ratio is 3
d
Geometric sequence; common ratio is −2
Answers
Answer:
d Geometric sequence; common ratio is −2
Step-by-step explanation:
Identifying Sequences
There are two possible types of sequences to choose from, Arithmetic and Geometric.
The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term. This number is called the common difference.
In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
The given sequence is:
48, -96, 192, -384, 768,....
To identify the type of sequence, we could try subtracting the second term from the first, the third from the second, etc. If those differences were constant, it would be an arithmetic sequence.
In this case, it's not necessary because the sign of the terms is alternating. It can only be possible with geometric sequences with a negative common ratio.
Dividing the second by the first term:
r = -96 / 48 = -2
Dividing the third by the second term:
r = 192 / -96 = -2
The rest of the divisions of successive terms lead to the same common ratio, thus, the answer is:
d Geometric sequence; common ratio is −2

100-45=55
45% men
55% women
There are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have:
A manufacturing plant has 60 supervisors. If 27 of the supervisors are men.
The number of women = 60 – 27 = 33
The percent of women = (33/60)×100
= 0.55×100
= 55%
Thus, there are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.
