Answer:
y=(-3/5)x + 5
Step-by-step explanation:
Looking at the graph, we can see two clear points; (0,5) and (5, 2). We know that the y-intercept is (0,5) so the b value of the standard form of a line, y=mx+b, is 5. Since we know two points, we can figure out the slope. So, the slope is (5-2)/(0-5) = 3/-5. Therefore the equation of this line is y=(-3/5)x+5. We can check this answer by plugging in points.

Explanations:
Problem 1
A = (4,4)
B = (-12,8)
Vector u starts at A and ends at B. The arrow points to B.
Subtract x coordinates: xB - xA = -12-4 = -16
Subtract y coordinates: yB - yA = 8-4 = 4
The vector is u = <-16, 4> which is in quadrant Q2.
Use the pythagorean theorem to find the length of the vector.
a^2 + b^2 = c^2
c = sqrt( a^2 + b^2 )
||u|| = sqrt( (-16)^2 + 4^2 )
||u|| = 16.492
Now compute the angle
theta = arctan(b/a)
theta = arctan(4/(-16))
theta = -14.036
Add on 180 degrees so the angle lands in Q2.
-14.036+180 = 165.964
The angle is roughly theta = 165.964 degrees
------------------------------
Problem 2
A = start point = (4, 3)
B = end point = (-4, -1)
Subtract x coordinates: xB - xA = -4 - 4 = -8
Subtract y coordinates: yB - yA = -1-3 = -4
v = <a, b> = <-8, -4> which is in Q3
Use the pythagorean theorem to find the length of the vector.
a^2 + b^2 = c^2
c = sqrt( a^2 + b^2 )
||v|| = sqrt( (-8)^2 + (-4)^2 )
||v|| = 8.944
And,
theta = arctan(b/a)
theta = arctan(-4/(-8))
theta = 26.565
We need to add on 180 so we move from Q1 to Q3
26.565+180 = 206.565
------------------------------
Problem 3
The notation <-3, 4> means "move 3 units left, 4 units up".
Only vector r fits the description as we move from the initial point (5,3) to the terminal point (2,7)

The perimeter of a rectangle is 60 cm. The ratio of length to width is 3:2. Find the length and width of the rectangle.
Answers
Given :
The Perimeter of the rectangle is 60 cmThe ratio of the length to the width is 3:2.To Find :
The Length and width of the rectangle .⠀
Solution :
We know that,
[tex]\qquad{ \bold{ \pmb{2(Length + Breadth ) = Perimeter_{(rectangle)}}}}[/tex]
Let's assume the length of the rectangle as 3x inches. and the width is 2x inches.
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \dashrightarrow{ \sf{2(3x + 2x )= 60}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(6x)= 60}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{12x= 60}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{x= \dfrac{60}{12} }}[/tex]

E + 60° + 45° = 180°
E = 180° - 105°
E = 75°
Then using sine rule:
[tex]\sf \dfrac{a}{sin(A)} = \dfrac{b}{sin(B)}[/tex]
[tex]\rightarrow \sf \dfrac{18}{sin(75)} = \dfrac{g}{sin(45)}[/tex]

QRST WXYZ. The area of QRST is given. Find the area of WXYZ.
Answers
Answer:
b. 1296 in^2
Step-by-step explanation:
The area of a rectangle is calculated by multiplying width and length:
The length of the QRST is 144 since its width is given as 8 to find the length:
144/8 = 18 is the length of the QRST
it is stated that the two rectangles are similar so their widths and lengths are proportional.
Let x represent the width of WXYZ:
8/24 = 18/x cross multiply expressions
8x = 432 divide both sides by 8
x = 54 now we can calculate area of WXYZ
24*54 = 1296
A 20,000 m^3 rectangular cistern is to be made from reinforced concrete such that the interior length will be twice the height. If the cost is $40/m^2 for the base, $100/m^2 for the side walls, and $200/m^2 for the roof, find the interior dimensions (to one decimal place) that will keep the cost to a minimum. To protect the water table, the building code specifies that no excavation can be more than 22m deep. It also specifies that all cisterns must be at least 1m deep
Answers
The volume of 20,000 m³, and the cost of $40/m², $100/m², and
$200/m², give the dimensions that give minimum cost as follows;
The height of the cistern is approximately 20.4 metersThe length is approximately 40.8 metersThe width is approximately 24.029 metersHow can the dimensions of the cistern be found?The dimensions of the cistern = L × W × H
L = 2·H
L × W × H = 20000
2·H² × W = 20000
[tex]W = \mathbf{ \dfrac{20000}{2 \cdot H^2}}[/tex]
Therefore;
A = 40·L·W + 200·L·W + 100·2·L·H + 100·2·W·H
A = 400·H² + 680·W·H
Given that the leading coefficient is positive, the function has a minimum point.
[tex]A = \dfrac{400 \cdot H^4 + 6800000 \cdot H}{H^2}[/tex]
[tex]\dfrac{d}{dH} A = \mathbf{\dfrac{d}{dH} \left( \dfrac{400 \cdot H^4 + 6800000 \cdot H}{H^2} \right)} = 0[/tex]
Which gives;
800·H⁵ - 6800000·H² = 0
800·H⁵ = 6800000·H²
H³ = 6800000 ÷ 800 = 8500
H ≈ 20.4 m
Which gives;
L ≈ 2 × 20.4 m = 40.8 m

In rectangle ABCD, the diagonals intersect each other at point 0 and mABD=30°.
Find BC if AC = 16 in.
Answers
Answer:
Step-by-step explanation:
The length of the diagonal BC is equal to 18.47in
Data;
m∠ABD = 30°
BC = ?
AC = 16 in
Length BC
Since the length of AC = 16in and angle m∠ABD = 30°, let us consider that the edges form a right angle triangle.
We can use trigonometric ratio to find the length BC since it is the length of the diagonal.
Since we have the value of opposite and angle, we can find the hypothenuse using sine angle.
The length of the diagonal BC is equal to 18.47in

Based on the tables given and the functions represented, the two functions that are inverses of each other are tables 3 and 4. Therefore, the options 3 and 4 are correct answers.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
When two functions are said to be inverses of each other, it means that the value of x is one is the corresponding value of y in the other function.
For instance, when the point is (5, 16) in one function, the other function's point would be (16,5).
Therefore, the options 3 and 4 are correct answers.

Answers
The mean of the normal distribution, using the formula for the z-score, considering the given data, is of 86.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The standard deviation is of [tex]\sigma = 5[/tex].5.48% of the area lies to the left of 78, hence when X = 78, Z has a p-value of 0.0548, that is, Z = -1.6.Then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.6 = \frac{78 - \mu}{5}[/tex]
[tex]78 - \mu = -1.6(5)[/tex]
[tex]\mu = 86[/tex]

If the width of a rectangle plot is “x” and the length of the plot is 100-x/2, what is the maximum area of the plot?
Answers
Answer:Let x = length of the plot (in meters).
Then the two lengths use up 2x meters of the fencing,
. . . leaving 100 - 2x meters for the two widths.
This means each width is (100 - 2x)/2 = 50 - x meters.
The area of a rectangle is: Length x Width
. . . so we have: . A .= .x(50 - x)
We have a <u>parabola</u>: . A .= .- x<sup>2</sup> + 50x</sup>
We know that this parabola opens down (don't we?)
. . . so its vertex must be the highest point.
We're expected to know that the vertex is at: . x = -b/2a
For this problem, a = -1, b = 50, so we have: . x = -50/(2(-1) = 25
We have maximum A when x = 25.
This leaves 50 - x = 25 for the width.
Therefore, for maximum area, make the plot a 25-by-25 square.
