Answers
Answer:
A) 11°
Step-by-step explanation:
All triangles equal 180, so:
102 + 67 + x = 180
169 + x = 180
x = 11

Answer:
Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3
Given the two points (-12, 18) and ( 24, -54) what is the slope?
Answers
Answer:
Slope = -2
Step-by-step explanation:
Use the equation to find a slope:
y2-y1/x2-x1 = slope
-54 - 18 = -72
24 - (-12) = 36
-72/36= -2

Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal count of everyone in the U.S. every 10 years and has provided the following data that gives the median age of an American man at the time of his first marriage.
What does it mean in this situation if the average rate of change is negative?
a.
It means that the median age of a man at the time of his first marriage is increasing.
b.
It means that the median age of a man at the time of his first marriage is decreasing.
c.
It means that the median age of a man at the time of his first marriage has a constant rate of change.
d.
There is no way to determine the average rate of change in this situation.
The Answer is D
Answers
Answer:
If the average rate of change in the data is negative, based on the variables analyzed;
b. It means that the median age of a man at the time of his first marriage is decreasing
Step-by-step explanation:
The given data is presented as follows;
Year; [tex]{}[/tex] 1910, 1920, 1930, 1940, 1950, 960, 1970, 1980, 1990, 2000
Median Age; [tex]{}[/tex] 25.1, 24.6, 24.3, 24.3, 22.8, 22.8, 23.2, 24.7, 26.1, 26.8
The date points are plotted on a graph using Microsoft Excel
[tex]The \ average \ rate \ of \ change = \dfrac{The \ change \ in \ the \ median \ age}{The \ corresponding \ change \ in \ years \ (always \ +ve)}[/tex]The corresponding change in years, Δx, is positive because, we have;
Δx = x₂ - x₁ = Higher year - Previous year
Therefore, for a negative average rate of change, we have;
[tex]The \ average \ rate \ of \ change = -ve = \dfrac{The \ change \ in \ the \ median \ age}{+ve}[/tex]
∴ The change in the median age, Δy = +ve × (-ve) = -ve (negative)
Δy = -ve
∴ Δy = Median age for higher year - Median age for previous year = -ve
Median age for higher year = -(y) + Median age for previous year
Where 'y' is positive
∴ Median age for subsequent year < Median age for previous year
Therefore, if the average rate of change is negative, the median age of a man's first marriage is decreasing

mrs susan bought 1/8 8m of curtain choth she used 3/5 m to make a curtain for the living room window how many meters of choth we're not use
Answers
Answer:
[tex]\frac{19}{40}[/tex]
Step-by-step explanation:
The computation of the meters of cloth that were not use is shown below:
= Used for making a curtain - purchase of curtain cloth
[tex]= \frac{3}{5} - \frac{1}{8}\\\\= \frac{24 - 5}{40} \\\\= \frac{19}{40}[/tex]
Hence, the meters of cloth that was not used is [tex]\frac{19}{40}[/tex]
A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?
Answers
Answer:
zero
Step-by-step explanation:
The computation of the remainder when the number would be divided by 35
Let the number be x
So if x is divided by 5 gives the remainder 0
x = 0
And, if x is divided by 7 gives the remainder 0
x = 0
So if x is divided by 35 so the remainder is also zero

A polynomial function with zeros 1,6i, and -6 i is
Answers
Step-by-step explanation:
If -5 is a zero, then one of the factors must be (x+5). Typically, a problem will give you one complex root (zero), but you must infer that its conjugate is always another root. In this case, since 2+6i is a root, then 2-6i must also be a root.
Those factors must then be (x-(2+6i)) and (x-(2-6i))
To get the final polynomial, multiply the factors together: (x+5)(x-2-6i)(x-2+6I)
I would multiply the complex factors first since they will typically simplify to a more workable expression.
(x - 2 - 6i)(x - 2 + 6i) = x2 - 2x + 6xi - 2x + 4 - 12i - 6xi + 12i - 36i2
= x2 - 4x + 40
Then multiply this trinomial by the final factor: (x2 - 4x + 40)(x + 5)
= x3 + 5x2- 4x2- 20x + 40x + 200
= x3 + x2 + 20x + 200
To get a coefficient of 3, multiply this polynomial by 3.
3(x3 + x2 + 20x + 200) = 3x3 + 3x2 + 60x + 600
Answer: 3x3 + 3x2 + 60x + 600
3. Hessa is building a scale model of a park. She uses a scale of 12 cm to represent 1.5 m. a) The actual length of the bridge is 20 m. What is the length of the model bridge? b) In the model, the height of the climbing frame is 10 cm. What is the actual height of the frame?
Answers
Answer:
160cm
80cm
Step-by-step explanation:
If 12cm = 1.5m
convert cm to meter
1 meter = 12/1.5 = 8cm
20m = 20m x 8 cm = 160 cm
10cm = 10 x 8 = 80cm
