Answer:
a) 80
b) 56
Step-by-step explanation:
a) Calculate the volume of the the cup using volume of cylinder equation: [tex]V = \pi r^{2} h[/tex]
Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ([tex]in^3[/tex]).
You're given diameter, so use equation [tex]d/2 = r[/tex] to find radius.
Substituting these equations will give you: [tex]V = \pi (d/2)^2 h[/tex]
However, the given volume of the sink is 3000[tex]\pi[/tex], meaning that you should modify your results to match this value. Do not substitute [tex]\pi[/tex] for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5 [tex]\pi[/tex]
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form:
[tex]Vsink / V cup =[/tex] # of cups.
Note the the [tex]\pi[/tex] will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.

Edit: It seems you want to find the measure of the angle at vertex C.
Consider two vectors x and y, the first of which begins at vertex C and ends at B, and the other begins at C and ends at A. We want to find the angle between x and y. If γ (gamma) is the measure of this angle, then
x • y = ||x|| ||y|| cos(γ)
Translating these vectors so that they start at the origin O, we get
C to B : x = (-2, 2) - (6, -2) = (-8, 4)
C to A : y = (6, 4) - (6, -2) = (0, 6)
Compute the dot product of x and y :
x • y = (-8, 4) • (0, 6) = 24
Compute their magnitudes:
||x|| = √((-8)² + 4²) = 4√5
||y|| = √(0² + 6²) = 6
Solve for γ :
cos(γ) = (x • y) / (||x|| ||y||)
cos(γ) = 24/(24√5)
cos(γ) = 1/√5
γ = arccos(1/√5) ≈ 63.4349°

Travis drew this graph to plan his rectangular garden. The points on the graph mark the four corners of the fence around the garden. What will be the length and width of the fence around the garden? Explain your answer.
The length of the rectangular garden which Travis drew on graph is equal to the large side of the rectangle made by four points and width is equal to short side.
What is the perimeter of a rectangle?The measure of the boundary of the sides of a rectangles called its perimeter. The perimeter of a rectangle is twice the sum its length and width.
P=2(l+w)
Here, (l) is the length of the rectangle and (w) is the width of the rectangle.
Travis drew a graph to plan the rectangular garden he has. The points over the graph marked are the four corners of the fence around the garden.
Now let suppose the two corner marked are with total distance of x while other two with total distance of y. Then the length will be x and width will be y.
Thus, the length of the rectangular garden which Travis drew on graph is equal to the large side of the rectangle made by four points and width is equal to short side.

Which expression represents the perimeter, in units, of this trapezoid? (45 points)
Answer:
A. 7x + 3
Step-by-step explanation:
The perimeter of a 2D shape is the distance all the way around the outside.
⇒ perimeter = (2x + 1) + (x + 1) + (3x - 1) + (x + 2)
= 2x + 1 + x + 1 + 3x - 1 + x + 2
= 2x + x + 3x + x + 1 + 1 - 1 + 2

Write an equation for the function graphed above.
The equation of the graphed function is [tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]
How to determine the equation of the graph?The graph is a secant graph, and it has the following form
[tex]y = a\sec(bx) + c[/tex]
From the graph, we have the following parameters:
The amplitude (a) is calculated using:
a = 0.5 *(Local minimum - Local maximum)
a = 0.5 *(5 + 1) = 3
The vertical shift (c) is calculated using:
a = 0.5 *(Local minimum + Local maximum)
a = 0.5 *(5 - 1) = 2
The period (b) is calculated using:
[tex]b = \frac{2\pi}{T}[/tex]
This gives
[tex]b = \frac{2\pi}{6}[/tex]
Evaluate
[tex]b = \frac{\pi}{3}[/tex]
Substitute the values of a, b and c in [tex]y = a\sec(bx) + c[/tex]
[tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]
Hence, the equation of the graphed function is [tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

Find the volume. Show work!!
Step-by-step explanation:
this is a combined object :
there is the basic block at the bottom (21×21×17), and there is a pyramid on top of it.
so, we need to calculate the volume of both parts and add them for the total volume.
the volume of the block is, as mentioned :
21 × 21 × 17 (length×width×height) = 7,497 ft³
the volume of a pyramid is
length×width×height/3
which is in our case
21 × 21 × 9 / 3 = 21 × 21 × 3 = 1,323 ft³
so, the total volume is
7,497 + 1,323 = 8,820 ft³

A town with a population of 5,000 grows 3% per year. Find the population at the end of 10 years
The population at the end of the 10 years is 6,500.
Given that,
A town with a population of 5,000 grows 3% per year.
We need to find the population at the end of 10 years.
Based on the above information, the calculation is as follows:
= 5,000 + 1,500
= 6,500
Therefore we can conclude that the population at the end of the 10 years is 6,500.

Find the minimum value of the function f(x) = 1.5x2 + 10x + 12 to the nearest
hundredth.
Answer:
-14/3
Step-by-step explanation:
Use derivative = 0 to find turning point(S)
D f(x) = 3x + 10 = 0
3x = - 10
X = - 10/3
When X = - 10/3
F(x) = 1.5(10/3)^2 - 10(10/3) + 12
= (3*10*10) / (2*3*3) - 100/3 +12
= 50/3 - 100/3 + 36/3
= - 14/3

find the diameter of the object
Answer:
4
Step-by-step explanation:
The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in the circle, to one directly across)
In this case, the radius is 2.
So, 2 x 2 = 4.
The diameter is 4.
4 in
Explanation:-The diameter of a circle is twice its radius. Here the given radius is 2 in.
So diameter = 2 in × 2 in = 4 in
______________Radius = Diameter/2
Diameter = Radius × Radius

initial population is 75,000. What will the population be after 10 years
Answer:
The population after 10 years will be 90,000.
Explanation:
2% of 75,000 is 1,500
the population will grow by 1,500 each year.
so 1,500 times 10 is 15,000
