What is the scale factor of this dilation?
Answers
Answer:
The scale factor of this dilation is [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The length of AC is 8, which is given. Since AC' is the dilated side that corresponds to AC, and the length is 4, that means the scale factor of dilation from ABC to AB'C' is [tex]\frac{4}{8}[/tex] or [tex]\frac{1}{2}[/tex].

what is the slope-intercept form of the equation of the line that contains the points (1,4) and (0,1)
Answers
Answer:
y = 3x + 1
Step-by-step explanation:
m = ( 1 - 4 ) / ( 0 - 1 ) = 3
( 0 , 1 )
y - 1 = 3(x - 0)
y - 1 = 3x
y = 3x + 1
Answer:
y=3x+1
Step-by-step explanation:
Slope is (y2-y1)/(x2-x1)
therefore slope =
(1-4)/(0-1)
-3/-1
m=3
therefore the equation is
y-y1=m(x-x1)
y-4=3(x-1)
y-4=3x-3

Write an equation of the parabola in vertex form that passes through (13,8) and has vertex (3,2).
Answers
Answer:
[tex]y=\frac{3}{50} (x-3)^{2}+2[/tex]
Step-by-step explanation:
Vertex: (3,2)
Point: (13,8)
The equation form is [tex]y=a(x-h)^2+k[/tex]
h = 3
k = 2
y = 8
x = 13
Plug in the values into the form..
[tex]8=a(13-3)^{2} +2[/tex]
Simplify and solve for a..
[tex]8=a(10)^{2}+2[/tex]
[tex]8=100a+2[/tex]
[tex]100a=8-2[/tex]
[tex]100a=6[/tex]
[tex]a=\frac{6}{100} or \frac{3}{50}[/tex]
Plug a into the equation..

Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what is the range in the context of this problem?
Answers
Answer:
The range is 0-25 feet
Step-by-step explanation:
Mathematically, when we are talking of the range, we are simply referring to the values at the boundaries.
This refers to the y-axis values. That is the values of the dependent variable
If we are to plot the graph, we will have the time on the x-axis while the amount of time spent in air would be on the y-axis
The base height is from the ground which is marked 0 feet to a maximum height of 25 feet
So the range in the context of this problem is 0-25 feet

The 14 compact cars sold by a dealer on Monday was 56% of the cars sold that day.
step by step please
Answers
the 14 cars sold = 56% of total car stock
how many cars (noted n) for 100 % ?
14.............56%
n..............100%
n x 56% = 14 x 100%
n = 14 : 0,56
n = 25
total cars in stock : 25
56% were sold
so 25 x 56% = 14 have been sold
If f(x)=x^2+3 and g(x)=2x-5 find (f-g) (x)
Answers
Answer:
[tex](f - g)(x) = x^2-2x-2[/tex]
Step-by-step explanation:
We have the following two functions:
[tex]f(x)=x^2 +3g(x) = 2x-5[/tex]
In order to solve for [tex](f - g)(x)[/tex] we look at the two functions and realize that:
[tex](f - g)(x) = f(x) - g(x) = x^2+3-2x-5=x^2-2x-2[/tex]
Therefore:
[tex](f - g)(x) = x^2-2x-2[/tex]
