Answer:
y = -1/3x - 7/3
Step-by-step explanation:
To find the slope, you have to plug the values into the slope formula.
y2 - y1/ x2 - x1
-4 - (-2) / 5 - (-1)
-1/3
Now to find the y-intercept, plug in one of the coordinates into the equation.
y = -1/3x + b
-2 = -1/3(-1) +b
-2 = 1/3 + b
-7/3 = b
The equation is y = -1/3x - 7/3.
The Solution is Y = - ( 1 / 3 )X - 7 / 3 where points are ( 5 , - 4) and ( - 1 , - 2) that passes through a straight line. Y = MX + C is the Formula for Straight line equation.
As per given problem, M is Slope
M = (Y2 - Y1) / (X2 - X1)
M = (- 4 - (- 2)) / ( 5 - (- 1))
M = - (1 / 3)
Now, Line becomes
- 2 = - ( 1 / 3) x (- 1)+ C
- 2 = 1 / 3 + C
C = - (7 / 3)
So, Solution: Y = - (1 / 3)X - (7 / 3)

what is the height of the tree
A. 156 ft
B. 100 ft
C. 80 ft
D. 25 ft
Answer:
B
Step-by-step explanation:
You first must find the conversion rate. Since you know a 4 ft tall object produces a 5 foot long shadow, you simply divide 4 by 5. This gives you 0.8. Now that you have your conversion rate, you multiply it by the shadow the tree casts, that being 125, and your answer is B, 100.

Step-by-step explanation:
Supplementary angles are angles whose measures sum to 180°.
equation for supplementary angle~ a+b=180
Example:
2x+(2x–2)=180
4x–2=180
4x=182
x=45.5
Answer:
x = 100.5
Step-by-step explanation:
Supplementary angles are two angles that have a sum of 180°. THIS MEANS WE'RE ADDING.
We can use distributive property to solve this equation.
x + (x-21) = 180°.
x + x - 21 = 180°.
Now, we can combine like terms.
2x - 21 = 180.
Since there is a subtraction sign in front of the number 21, we do the opposite operation (addition).
Next, we add 21 to 180.
180 + 21 = 201.
2x = 201
Lastly, we divide 201 by 2.
The quotient is 100.5.
100.5 is the final answer.
Therefore, 100.5 is the value of x.
We can check our answer to make sure.
(100.5 - 21) + 100.5 =
79.5 + 100.5 = 180°.

A soccer dome shaped like a hemisphere has a volume of 450,000 m^3. What is the area of its field? Use 3.14 for pi
Answer:
Step-by-step explanation:
450,000=2/3(3.14)r
450,000 times 3/2=2/3(3.14)r times 3/2
675,000=3.14r
675,000/3.14=3.14r/3.14
about 214968.15287=r
So now we know r. We can use it to find the area of the circle
Pi times r squared
3.14 times 214968.15287 squared
area equals about 15573.44815
The area of the hemisphere is 45065.41
How to determine the area?The given parameters are:
Shape = Hemisphere
Volume = 450000
The volume is calculated as:
Volume = 2/3pi r^3
This gives
450,000=2/3 * 3.14 * r^3
Solve for r^3
r^3 = 450000 * 3/(2 * 3.14)
This gives
r^3 = 214968.152
Take the cube roots
r = 59.9
The area is then calculated as;
Area = 4pi r^2
This gives
Area = 4 * 3.14 * 59.9^2
Evaluate
Area = 45065.41
Hence, the area of the hemisphere is 45065.41

Ms. Brodie drew these box-and-whisker plots to represent her students' scores on the mid-year test and the final exam.
What do the plots tell you about the test scores of Ms. Brodie's class?
Answer:
The scores of the final exam are, in general, lower than the scores in the mid-term exam.
Step-by-step explanation:
First a little description of these graphs.
The first interval (only a line) represents the bottom 25% of the sample.
The second interval (the left part of the rectangle) represents the lower quartile, which is another 25% of the sample.
The third interval, the right part of the rectangle, represents the upper quartile, which is another 25% of the sample.
And the final segment represents the top 25%.
Looking at the first graph, we can see that the worst scores (for the bottom 25%) are between 44 and 63.
While in the second graph, the wors scores are between 44 and 59, this means that we have more people with bad scores in the final exam.
Now if we look at the lower quartile in the first graph, we can see that the range of scores is between 63 and 74.
While in the second graph the range is between 59 and 71.
Again, we can see that in the final exam the scores dropped a bit in this quartile.
In the upper quartile, we have a similar case.
In the first graph, the scores go between 74 and 81, while in the second graph the scores go between 71 and 79.
And in the final segment, we also can see a drop in the scores, because in the first graph the range is from 81 to 93
while in the second graph the range is from 79 and 92.
So in all the "segments", we can see that the scores dropped. And this is the only conclusion we can make from the graphs, the scores of the final exam are, in general, lower than the scores in the mid-term exam.

Step-by-step explanation:
Given that <ACB = <ECD, then triangles ABC and EDC are similar.
Let the height of the solar panel (AB) be represented by x. Thus by comparing the triangles, we have;
[tex]\frac{x}{6}[/tex] = [tex]\frac{45}{75}[/tex]
45x = 6 x 75
45x = 450
x = [tex]\frac{450}{45}[/tex]

1. What is the equation of a parabola that has a vertex at (-2, 4) and goes through the point (0,8)?
Answer:
y - k = (x + 2)^2
Step-by-step explanation:
The vertex equation of a vertical parabola is
y - k = a(x - h)^2, where (h, k) is the vertex.
We are given h = -2, k = 4, x = 0 and y = 8 and need to find the value of a.
8 - 4 = a(0 + 2)^2, or
4 = 4a, so a must be 1.
Then the desired equation is:
y - k = (x + 2)^2

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Each girl spent $12.
Afterward, the girls had $24 altogether.
let each Girl received amount of $x.
So, the four spend = 12 x 4 = $48
Then, the total they have = 48 + 24 = $72
So, each of Girl have = 72/ 4 = $18.

Answer:
h = 4.5 units
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 6.75 and b = 3 , then
[tex]\frac{1}{2}[/tex] × 3h = 6.75
1.5h = 6.75 ( divide both sides by 1.5 )
h = 4.5
we have
base [b]=3 units
height [h]=x units
area of triangle =6.75 square units
we have
area of triangle =1/2 b×h
6.75 square units =1/2×3×x
x=6.75×2/3=4.5units
so height is 4.5 units.
