Answer:
D. [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Rectangle VWXY after dilation, became compressed to rectangle V'W'X'Y'.
This makes both rectangles similar. It follows that the corresponding side lengths or segments of both figure would be proportional. Thus, the scale factor of the dilation would be:
[tex] \frac{W'X'}{WX} [/tex]
W'X' = 5
WX = 20
Plug in the values
[tex] \frac{5}{20} [/tex]
Simplify
[tex] scale factor = \frac{1}{4} [/tex]

(4*n)=40
4*10=40
n=40
What is the slope and why?
Answer:
Step-by-step explanation:
ok slope is m because there is a thing called y-intercept, so you use x to find slope.
the whole formula is y = mx +b
in this case m = slope with x being the part of the slope from where you got it from
the answer would be m = [tex]\frac{1}{2}[/tex]x

Which is the solution for ln(3x - 5) = ln(11) + ln(2) ?
Answer:
B: x=9
Step-by-step explanation:
You have to use the property of logarithms
that says ln A + ln B = ln AB. So here we have
ln (3x - 5) = ln 11 + ln 2 = ln 22
Therefore 3x - 5 = 22, from which x = 9

Answer:
C
Step-by-step explanation:
Answer:
C. x < -175
Step-by-step explanation:
-1/5x + 4 < 39
minus 4 on both sides
= -1/5 < 35
multiply by -5 because we want the X to be positive, always. And when we multiply or divide by a negative number, the sign will always flip.
X > -175

Explanation:
Sort the values from smallest to largest: {2, 5, 6, 10, 10}
Now cross off the first and last values to get this smaller set: {5, 6, 10}
Repeat the process one more time and we get this: {6}
This shows 6 is the middle most item of the original sorted set above. Therefore, 6 is the median.
Which function has an inverse that is a function?
b(x) = x2 + 3
d(x) = –9
m(x) = –7x
p(x) = |x|
Answer:
All but the second one
Step-by-step explanation:
Find the inverse of each function:
b(x)=x^2+3
y=x^2+3
x=y^2+3
x-3=y^2
sqrt(x-3)=y
This inverse function is a function
d(x)=-9
y=-9
This doesn't have an inverse function
m(x)=-7x
y=-7x
x=-7y
-1/7x=y
This inverse function is a function
p(x)=|x|
y=|x|
x=|y|
x=y
This inverse function is a function
Therefore, all but the second function have inverses that are functions
Answer:
All but the second one have inverse functions

Which function best models the data set?
Answer:
C
Step-by-step explanation:
I got it right
The function that best models the data set is y = 3x + 11
What is the slope of the line?"The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"
What is the equation of the line passing through two points?"The equation of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is, [tex]\frac{y-y_1}{y_2-y_1} =\frac{x-x_1}{x_2-x_1}[/tex] "
For given question,
If we draw the line of best fit, then the the line would pass through points (3, 20) and (8, 35)
Let [tex](x_1,y_1)=(3, 20),(x_2,y_2)=(8, 35)[/tex]
Then the equation of the line would be,
[tex]\Rightarrow \frac{y-y_1}{y_2-y_1} =\frac{x-x_1}{x_2-x_1} \\\\ \Rightarrow \frac{y-20}{35-20} =\frac{x-3}{8-3} \\\\ \Rightarrow \frac{y-20}{15} =\frac{x-3}{5} \\\\ \Rightarrow y-20=15\times \frac{x-3}{5}\\\\ \Rightarrow y-20=3(x-3)\\\\ \Rightarrow y-20=3x-9\\\\ \Rightarrow y=3x+11[/tex]
Therefore, the function that best models the data set is y = 3x + 11

Answer:
1 / 8², B
Step-by-step explanation:
8 / 8³
8³ = 8*8*8
So, the equation can also be written as:
8 / 8*8*8
divide the numerator and denominator by 8.
1 / 8*8
This is equal to:
1 / 8²
The answer is B.

Answer:
The graph of the function is the set of all points (x,y) in the plane that satisfies the equation y=f(x) y = f ( x ) . ... A vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value.

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of where it was tied and 30 feet above the ground, as shown in the figure below. What is the slope of the line between the balloon and the point where it was tied?
Answer:
The slope is 0.55
Step-by-step explanation:
Right Triangles
The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.
The image below shows the geometric construction. We are required to find the slope the string forms with the ground.
It can be found by using the tangent ratio:
[tex]\displaystyle \tan\theta=\frac{y}{x}[/tex]
Substituting y=30 and x=55
[tex]\displaystyle \tan\theta=\frac{30}{55}[/tex]
[tex]\displaystyle \tan\theta=0.55[/tex]
The slope is 0.55
