Graph B (bottom left)
Step-by-step explanation:
Let's eliminate answers by reading the prompt:
Jaelene drains some of the water from a pool at a constant rate.
These are two big clues. Since Jaelene drains water, she is losing water, and at a constant rate. Therefore, we can eliminate A and C because you would be gaining water in the pool and not draining.
She stops draining water to fix the hose and then fills the pool up with water again.
Also important clues. If you stop draining water, the water level does not change. Also, since the pool is filling up, that means we are gaining water. Therefore, we can eliminate option D because that would mean we're still draining water but we're not in this case.
Therefore, the only correct answer is graph B (bottom left)

Assuming there are no reflections or dilations,
explain how you would write the oquation of the
function whose graph is sketched below.
Answer:
Step-by-step explanation:
We can see that this graph looks something like the graph of:
f(x) = 1/x^2
But the asymptotes of 1/x^2 are at x = 0, and in this case we can see that the asymptotes are near x = -3.
This may mean that the graph has been horizontally shifted 3 units to the left.
A general way to write an horizontal shift of N units is:
g(x) = f(x + N)
if N is positive, then the shift is to the left, if N is negative, then the shift is to the right.
In this case, we will have;
g(x) = f(x + 3)
And f(x) = 1/x^2
then:
g(x) = 1/(x + 3)^2
Graphing that, we get the graph shown below, that is almost the same as the graph in the image.

Step-by-step explanation:
in the coordinate plane, triangle ABC has vertices A(1,-2), B(1,0.5), and C(2,1) and triangle DEF has vertices D(4,-3), E(4,2), and F(6,3). The triangles are similar because DEF is the image of ABC under a dilation with center (_,_) and scale factor ___.
PLEASE HELPP
Answer:
(A) the center of dilation is at (-2,-1)
(E) the scale factor is 2
The triangle DEF is a dilation of triangle ABC with center of dilation at (0,0) and scale factor of 0.5.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The ratio of the lengths of corresponding sides of triangles ABC and DEF.
AB and DE are corresponding sides, so:
AB/DE = (distance between A and B) / (distance between D and E)
= 2.5 / 5
= 0.5
BC and EF are corresponding sides, so:
BC/EF = (distance between B and C) / (distance between E and F)
=1.118 / 2.236
= 0.5
AC and DF are corresponding sides, so:
AC/DF = (distance between A and C) / (distance between D and F)
AC/DF = 2.236 / 4.472
= 0.5
We see that all three ratios are equal to 0.5.
Hence, the triangle DEF is a dilation of triangle ABC with center of dilation at (0,0) and scale factor of 0.5.

Find the missing angles
Please try to give a good explanation so I can learn how it was done! Thank you
Answer:
Explained below.
Step-by-step explanation:
1. Bisecting splits an angle into two equal parts. Angle 2 and 3 are now equal.
2. And since it is a right angle, both angles are 45 degrees.
3. All triangle angles will ALWAYS add up to 180.
4. Angle 4 = 180 - 45 (Angle 3) -83.
Angle 4 = 52.
5. Do same thing for Angle 1.
6. Angle 1 = 180 - 45 (Angle 2) - 48
Angle 1 = 87.
Final answers.
1. 87 degrees
2. 45 degrees.
3. 45 degrees.
4. 52 degrees.

Answer:
[tex] x \ge 15 [/tex]
Step-by-step explanation:
An isosceles ∆ has 2 equal sides. The perimeter of a ∆ is the sum of all its sides.
Given that the perimeter of the triangle above is "at least 137 ft", this means the sum of all its sides is equal to or greater than 137 ft.
Thus, using inequality, this can be represented as:
[tex] 2(2x + 7) + 4x + 3 \ge 137 [/tex]
Solve for x
[tex] 4x + 14 + 4x + 3 \ge 137 [/tex]
Add like terms
[tex] 8x + 17 \ge 137 [/tex]
Subtract 17 from both sides
[tex] 8x + 17 - 17 \ge 137 - 17 [/tex]
[tex] 8x \ge 120 [/tex]
Divide both sides by 8
[tex] \frac{8x}{8} \ge \frac{120}{8} [/tex]
[tex] x \ge 15 [/tex]

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio.
A(-6, 9), B(2, 1); Ratio 5 to 3
Answer:
The coordinates of the point P = (x, y) = (-1, 4)
Step-by-step explanation:
Let the coordinates of P be (x, y)
(x₁, y₁) = (-6, 9)(x₂, y₂) = (2, 1)ratio = m:n = 5:3Using the section formula
x = [(mx₂ + nx₁)] / [(m+n)]
= [5(2)+3(-6)] / [5+3]
= [10-18] / [8]
= -8/8
= -1
y = [(my₂ + ny₁)] / [(m+n)]
= [5(1)+3(9)] / [5+3]
= [5+27] / [8]
= 32/8
= 4
Therefore, the coordinates of the point P = (x, y) = (-1, 4)

Lana makes eight dollars an hour Plus $12 an hour for every hour overtime. Overtime hours are any hours more than 40 hours for the week create an equation that shows the amount of wages earned, W, for working X hours in a week when there is no overtime
Answer:
W = $8X
Step-by-step explanation:
Lana makes $8 per hour
Extra $12 an hour for every hour overtime
Overtime are hours more than 40 hours per week
In this case, Lana worked for X hours with no overtime
If W is wages earned for working for X hours , the equation will be;
W= X * $8

Answer:
B
Step-by-step explanation:
It's B because Alex wants to spend exactly $30, and since he has to pay $18 as a charge and $0.12 per mile, you would have to add those two together to get $30. Since you're spending money per mile and the charger, you have to add them.

A farmer conducted a hypothesis test to see if a new type of soybean would grow better on their land. The alternative hypothesis is the new seed will on average grow more than the old soybean type. The farmer runs a controlled experiment and finds a p-value of .345. The farmer comes to the conclusion that there is no evidence that the new soybean will lead to a larger harvest. What error(s) is it possible to commit
Answer:
Type 2 Error
Step-by-step explanation:
Null Hypothesis [H0] : New soybean has no impact on harvest
Alternate Hypothesis [H1] : New soybean leads to larger harvest
The farmer accepts the null hypothesis & concludes, that there is no impact of new soybean on harvest.
He could have committed Type 2 Error, which refers to accepting a null hypothesis when it is actually false.

We are given:
Parallelogram CDEF∠C = 13x - 10∠D = 5x + 10To Find: ∠E
Concept Used:
Adjacent angles of a Parallelogram are SupplementaryFinding the value of 'x':
Since adjacent angles of a parallelogram are Supplementary:
∠D + ∠C = 180
5x + 10 + 13x - 10 = 180 [replacing the values of angle C and D]
18x = 180
x = 10 [dividing both sides by 18]
__________________________________________________________
Finding Measure of Angle D:
We are given that:
∠D = 5x + 10
∠D = 5(10) + 10 [since x = 10]
∠D = 60°
__________________________________________________________
Finding the measure of ∠E:
∠D and ∠E are Adjacent angles
Since Adjacent angles are Supplementary:
∠D + ∠E = 180
60 + ∠E = 180
∠E = 120° [subtracting 60 from both sides]
Hence, the measure of ∠E = 120°

Which of these is a point-slope equation of the line that is perpendicular to

A. y-7= -2(x+ 3)
B. y+7=--3)
C.y-7- -x+3)
D. y+7 = 2(x- 3)
Given:
Equation of line is [tex]y-25=2(x-10)[/tex].
A line is perpendicular to the given line and passes through (-3,7).
To find:
The point slope form of the perpendicular line.
Solution:
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex] ...(i)
where, [tex](x_1,y_1)[/tex] is the point from which the line is passing through and m is slope.
We have,
[tex]y-25=2(x-10)[/tex] ...(ii)
From (i) and (ii), we get
[tex]m_1=2[/tex]
Product of slopes of two perpendicular lines is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]2\times m_2=-1[/tex]
[tex]m_2=-\dfrac{1}{2}[/tex]
So, slope of perpendicular line is [tex]-\dfrac{1}{2}[/tex].
Point slope form of the perpendicular line is
[tex]y-(7)=-\dfrac{1}{2}(x-(-3))[/tex]
[tex]y-7=-\dfrac{1}{2}(x+3)[/tex]
Therefore, the correct option is C.
