Answer:
width=25/3
Length=75/3
Step-by-step explanation:
Given
Perimeter=50
Let width=x
Length=4x
So perimeter =2(length+width)
2(length+width)=50
2(X+2x)=50
3x=25
X=25/3
So width=25/3
Length=75/3
Denise proposes the following transformation rule for this rotation:
(x,y) ➝ (y+4, -x-2)
Does this rule work? Justify your answer.
Answer:
The proposed rule correctly works.
Step-by-step explanation:
As the original triangle has the vertices with the coordinates
A(-6, 6)B(-6, 1)C(-2, 1)From the given diagram, the image of the triangle has the vertices
A'(10, 4)
B'(5, 4)
C'(5, 0)
According to the proposed rule, the image should have the following vertices.
(x,y) ➝ (y+4, -x-2)
A(-6, 6) ➝ (6+4, -(-6)-2) = A'(10, 4)
B(-6, 1) ➝ (1+4, -(-6)-2) = B'(5, 4)
C(-2, 1) ➝ (1+4, -(-2)-2) = C'(5, 0)
So, the coordinates of the image of the triangle are correctly drawn as per the proposed rule.
Therefore, the proposed rule correctly works.
Which finds the solution to the equation represented by the model below?
O removing 1 x-tile from each side
O removing 3 unit tiles from the right side
O adding 3 positive unit tiles to each side
O arranging tiles into equal groups to match the number of x-tiles
Answer:
removing 1 x-tile from each side.
Step-by-step explanation:
the question is asking to isolate x and the equation is 2x = x + 3.
to isolate x subtract each side by an x-tile
Answer:
The answer is A

The table below shows an input/output relationship. Find the Starting Value/y-intercept.
Answer:
Input 0 and Output -6
Step-by-step explanation:
The reason why is that we know that -4 has a output of -18 which -3 has a output of -15 meaning each time x increases by 1 the output increases by 3. 1:3 ratio basically so since we know this the starting value should be
y=0+3x

I am just not sure if I did this properly. My professor hasn't really gone over when to use the range equation but I would assume range would equal the distance traveled therefore can be used for this problem. If not the how would I go about solving this? I did 1/6*9.8=1.63 for g on the moon Then used R=(Vi^2sin2theta)/g so on the moon R=((28^2)sin2*35)/1.63=452m

Write an equation of the line, in point-slope form, that passes through the two given points. points: (-3,18). (12,-12)
Answer:
y = -2x + 12
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-12 - 18) / (12 + 3)
-30 / 15
= -2
Then, plug this and a point into y = mx + b and solve for b:
y = mx + b
-12 = -2(12) + b
-12 = -24 + b
12 = b
Then, plug in the slope and b into y = mx + b
y = -2x + 12 is the equation of the line

Answer: 6
Step-by-step explanation:
Answer:
42/7 or 6
Step-by-step explanation:
First, let's start off with the top part. 6^2 is 6 times 6, which is 36. 36 + 6 = 42. Now for the bottom part, 4^2 is 4 times 4, which is 16. 3^2 is 9. 16-9=7. 42/7 is the fraction form and if you want it simplified, then it is 6.

Step-by-step explanation:
Most dermatologists recommend using sunscreens that have a Sun Protection Factor (SPF) of at least 30. One of the authors wanted to find out whether the SPF of sunscreens used by students at her school exceeds this value on average? To collect data, the author surveyed students in her introductory statistics course and found that in a sample of 52 students the mean SPF was 34.55 and the standard deviation of SPF was 20.12. The data were not strongly skewed.

Use the Theory-Based Inference applet to find and report the 95% confidence interval for the parameter of interest.
Answer:
95% confidence interval = ( 28.9485, 40.1515 )
Step-by-step explanation:
sample size( n ) = 52
mean value ( x )= 34.55
std ( б ) = 20.12
H0 : u ≤ 30
Ha : u > 30 ( claim )
95% confidence interval for mean SPF level ( df = 51 )
= mean value ± [tex](2.0076 + \frac{20.12}{\sqrt{52} } )[/tex]
95% confidence interval = ( 28.9485, 40.1515 )
we cannot reject H0

Step-by-step explanation:
12.7−xx=8.41
Multiply x and x to get x

.
12.7−x

=8.41
Subtract 12.7 from both sides.
−x

=8.41−12.7
Subtract 12.7 from 8.41 to get −4.29.
−x

=−4.29
Divide both sides by −1.
x
