DO NOT PUT YOU FAKE FILES HERE !
Answer:
Step-by-step explanation:
The water level decreases 2 gallons every 3 seconds describes the rate of change shown in the grap
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given that Ariel is emptying the water from a 10 gallon cooler.
The graph shows the water level in the cooler as she empties it
Rate of change is change in water to change in time
(3, 8) and (0, 10) are the points from graph
Rate of change = 10-8/0-3
=-2/3
The minus sign is showing that is is decreasing
The water level decreases 2 gallons every 3 seconds
Hence, the water level decreases 2 gallons every 3 seconds describes the rate of change shown in the graph.

Answer:
x=9/4,x=-9/4
Step-by-step explanation:
16x^2−81=0
Step 1: Add 81 to both sides.
16x^2−81+81=0+81
16x^2=81
Step 2: Divide both sides by 16.
16x^2/16 = 81/16
x^2 = 81/16
Step 3: Take square root.
x = ±√81/16
x=2.25,x=−2.25

Need help ASAP no fake links!!! Find the measure of angle C, and find the measure of Arc BC
Answer:
[tex]\huge \purple {\boxed { m\angle C = 47\degree}} [/tex]
[tex] \huge \red {\boxed { \widehat{BC}=96\degree}} [/tex]
Step-by-step explanation:
By inscribed angle theorem:
[tex] m\angle C = \frac{1}{2} m(\widehat{AD}) [/tex]
[tex] \therefore m\angle C = \frac{1}{2}\times 94\degree [/tex]
[tex]\huge \purple {\boxed {\therefore m\angle C = 47\degree}} [/tex]
Again by inscribed angle theorem:
[tex] m\angle A = \frac{1}{2} m(\widehat{BC}) [/tex]
[tex] \therefore 48\degree = \frac{1}{2} m(\widehat{BC}) [/tex]
[tex] \therefore 48\degree\times 2 = m(\widehat{BC}) [/tex]
[tex] \huge \red {\boxed {\therefore m(\widehat{BC}) =96\degree}} [/tex]

Jeremy had $32.50 in his savings account. He withdrew $4.50 each week for 3 weeks. How much money did he have left in the account after the 3 withdrawals?
Answer:
Jeremy have 19 dollars left.
Step-by-step explanation:
He withdrew $4.50 3 times, so he withdrew $4.50x3 = $13.50 in total
$32.50 — $13.50 = $19
Jeremy had 19 dollars left on his account.
Ling and her family ordered takeout that cost $50. Ling paid 4% sales tax and left a 10% tip
on $50. What was the total cost?
Answer:
57
Step-by-step explanation:
tax
= tax percentage×amount
= 0.04×50
= 2
The tax was $2.
tip
= tip percentage×amount
= 0.10×50
= 5
Based on the information given the total cost is $57.
Using this formula
Total cost=Takeout cost+ Sales tax +Tip
Where:
Takeout cost=$50
Sales tax=(4%×$50)=$2
Tip=(10%×$50)=$5
Let plug formula
Total cost=$50+$2+$5
Total cost=$57
Inconclusion the total cost is $57.

If θ is an angle in standard position and its terminal side passes through the point (21,-20), find the exact value of \cot\thetacotθ in simplest radical form.
The exact value of the cotangent of theta in simplest radical form is -21/20.
What is the simplest radical form?
The simplest radical form is the expression of a radical without any factors inside the radical that can be further simplified.
To find the exact value of cotangent of theta, we need to find the values of cosine and sine of theta first.
Given that the terminal side of the angle passes through the point (21,-20), we can use the Pythagorean theorem to find the hypotenuse of the right triangle formed by the angle and the x and y-axes:
[tex]h = \sqrt{(21^2 + (-20)^2)} = \sqrt{(841 + 400)} = \sqrt{(1241)}[/tex]
Then, we can find the values of cosine and sine of theta using the x and y-coordinates of the point:
cos(theta) = adjacent/hypotenuse = 21/sqrt(1241)
sin(theta) = opposite/hypotenuse = -20/sqrt(1241)
Now we can find the value of cotangent of theta:
cot(theta) = cos(theta) / sin(theta) = (21/sqrt(1241)) / (-20/sqrt(1241))
= -21/20
Therefore, the exact value of the cotangent of theta in simplest radical form is -21/20.

Answer:
Equation B and Equation C
Step-by-step explanation:
We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

The volume of the box is 60 cubic inches. What are
the length, width, and height of the box?
Answer: The volume is the product of the Length, Width, and Height: V = LWH.
Step-by-step explanation: We are given V = 240 in.3, and H = 6 in., and L = W + 3 in.
Thus 240 in.3 = (W+3 in.)*W*(6 in.) so W(W+3 in.) = 240 in.3 / 6 in. = 40 in.2
Using the distributive property and moving the constant to the left gives:
W2 + (3 in.)W - 40 in.2 = 0
This factors:
(W + 8 in.)(W - 5 in.) = 0
The first factor gives W = -8 in. which is nonsense because it is negative.
The second factor gives a valid answer of W = 5 in.
