A(-10, 8) and B (-9,4).
C (-5, 12) and D (2,9).
Answers
Answer:
Neither
Step-by-step explanation:
Slope for AB is -4
Slope for CD is -3/7
in order to find the slope use this formula attached
AB -9-(-10) / 4-8 = -4 your y2 is 4 your y1 is 8 / x2 is -9 x1 is -10
CD 9-12 / 2-(-5) your y2 is 9 your y1 is 12 / x2 is 2 x1 is -5
Answer: The lines will be neither
Line A is Purple dot
Line B is Blue dot
Line C is Red dot
Line D is Green dot

C. x = 1.04
D. x= 0.40
Answers
Given:
The equation is
[tex]5^x=55[/tex]
To find:
The value of x.
Solution:
We have,
[tex]5^x=55[/tex]
Taking log both sides, we get
[tex]\log (5^x)=\log (55)[/tex]
[tex]x\log (5)=\log (55)[/tex] [tex][\because \log x^n=n\log x][/tex]
[tex]x=\dfrac{\log (55)}{\log (5)}[/tex]
Using the log values, we get
[tex]x=\dfrac{1.740}{0.699}[/tex]
[tex]x=2.48927[/tex]
[tex]x\approx 2.49[/tex]
Therefore, the correct option is B.

The volume and base area of a rectangular cargo container is 720 cubic
meters and 120 square meters. Find the height of the container? *
A)86,400m3
B)400m3
C)4m
D)6m
Answers
Answer:
D, 6m
Step-by-step explanation:
Step one:
Given data
The volume and base area of a rectangular cargo container is 720 cubic
= 720m^3
The area of the cargo container is 120 m^2
Required
We want to find the height of the container
Step two
The expression for the volume is given as
Volume= Area* height
so,
720= 120*h
divide both sides by 120
720/120= h
h= 6 m
The height is 6m

Answers
Answer:
5.5
Step-by-step explanation:
Given the set of data
5, 4, 2, 1, 1, 2, 10, 2, 3, 5.
The average of the least and the greatest value is known as the midrange
The formula for calculating the midrange is expressed as shown:
Midrange = (Greatest value + Least value)/2
Given
Greatest value = 10
Least value = 1
Midrange = 10+1/2
Midrange = 11/2
Midrange = 5.5
Hence the midrange of the data is 5.5
