Oscar wants to fill with water a bucket that is the shape of a right circular cylinder. It has a 6-inch radius and12-inch height. He uses a shovel that has the shape of a right circular cone with a 3-inch radius and 4-inch height. How many shovelfuls will it take Oscar to fill the bucket up level with the top?
Answer: I think it is 36 shovelfuls
Step-by-step explanation:
V = πr²h
V = π • 6² • 12
V = π • 36 • 12
V = 1357.2in³
V = 1/3πr²h
V = 1/3 • π • 3² • 4
V = 1/3 • π • 9 • 4
V = 1/3 • π • 36
V = 37.7in³
1357.2 ÷ 37.7 = 36 shovelfuls

A trunk measures 48 inches long, 22 ½ feet wide, and 32 inches high. What is the volume of the box? Answer without units
Answer:
Volume of trunk = 4,14,720 inches³
Step-by-step explanation:
Find:
Length of trunk = 48 inches
Width of trunk = 22 ½ feet = 45 / 2 = 22.5 feet
Height of trunk = 32 inches
Find:
Volume of trunk
Computation:
1 feet = 12 inch
Width of trunk = 22.5 feet
Width of trunk = 22.5 x 12
Width of trunk = 270 inches
Volume of trunk = Length x Width x Height
Volume of trunk = 48 x 270 x 32
Volume of trunk = 4,14,720 inches³

Answer and Step-by-step explanation:
The answer is 54.
We see that each time, the number is being multiplied by 1.5.
54 times 1.5 = 81 * 1.5 = 108
54 times 2 = 108
54 is the starting number, because when you multiply 54 by 1, you get 54 for y.
#teamtrees #PAW (Plant And Water)
Answer: y = 54x
The easiest way to do this is by looking at the column where x = 1. In that column, y = 54, so we know that x times 54 would be equal to y.
If you don't have a column where x = 1, you can divide the y value by the x. Here are two examples:
27 ÷ 0.5 = 54
81 ÷ 1.5 = 54

How would the graph of the function y=|x|-4 be affected if the function were changed to y=|x|-1?
Answer:
[tex]y =|x| - 4[/tex] is translated 3 units up
Step-by-step explanation:
Given
[tex]y =|x| - 4[/tex]
Required
The changes that makes it to: [tex]y =|x| - 1[/tex]
By observation, we can see that [tex]y =|x| - 4[/tex] was translated up to [tex]y =|x| - 1[/tex]
Next, is to calculate the units of translation (c)
Represent the old function as:
[tex]y=\left|x\right|-4 + c[/tex]
Equate y and y
[tex]\left|x\right|-4 + c =\left|x\right|-1[/tex]
Cancel out |x|
[tex]-4 + c=-1[/tex]
Solve for c
[tex]c = 4 - 1[/tex]
[tex]c = 3[/tex]

is 0.27 greater than 0.3 ?
Answer:
No
Step-by-step explanation:
here's a little trick, add a zero to make both numbers the same.
it's doesn't change the value.
so .27 and .3 become .27 and .30
and .30 is greater

Find the percent of the area under the density curve where x is more than 3.
Answer:
The percent of the area under the density curve where [tex]x[/tex] is more that 3 is 25 %.
Step-by-step explanation:
Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression:
[tex]A = \frac{1}{2}\cdot (x_{f} - x_{o})\cdot (y_{f}-y_{o})[/tex] (1)
Where:
[tex]A[/tex] - Area, in square units.
[tex]x_{f} - x_{o}[/tex] - Base of the triangle, in units.
[tex]y_{f} - y_{o}[/tex] - Height of the triangle, in units.
The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:
[tex]x = \frac{\frac{1}{2}\cdot (5-3)\cdot (0.25) }{\frac{1}{2}\cdot (5-1)\cdot (0.5) }\times 100\,\%[/tex]
[tex]x = 25\,\%[/tex]
The percent of the area under the density curve where [tex]x[/tex] is more that 3 is 25 %.

If JK= 2x, KL=8, and JL= 4x, what is JK?
(On a line segment)
J 2x K 8 L
|—————————-|————————-|
4x
^_____________|_____________^
Answer:
JK = 8
Step-by-step explanation:
As JK + KL = JL.
2x + 8 = 4x
–2x –2x
8 = 2x
÷2 ÷2
4 = x.
x = 4.
JK = 2x.
x = 4 → JK = 2x → JK = 2(4) → JK = 8.
Find the critical points of the following functions. Use the Second Derivative Test to determine (if possible) whether each critical point corresponds to a local maximum, a local minimum, or a saddle point. If the Second Derivative Test is inconclusive, determine the behavior of the Junction at the critical points. f(x,y)=x^4y^2
Answer:
In a function of two variables, the critical points are these in which both derivatives are 0, and if:
[tex]\frac{d^2f}{dx^2}*\frac{d^2f}{dy^2} - [ \frac{d^2f}{dxdy} ]^2 < 0[/tex]
the point is a saddle point.
If the above equation is larger than zero, the critical points can be either a local maximum or a local minimum.
If it is equal to zero, no conclusions can be made.
First, let's find all these derivatives.
df/dx = 4*(x^3)*(y^2)
This is zero when x or y are equal to zero.
df/dy = 2*(x^4)*(y)
This is equal to zero when either x or y are equal to zero.
So in both cases, the points of the form:
(x, 0) and (0, y) are zeros of the first derivative, so these are the critical points.
Now let's look at the second derivatives:
[tex]\frac{d^2f}{dx} = 4*3*x^2*y^2 = 12*x^2*y^2[/tex]
[tex]\frac{d^2f}{dy^2} = 2*x^4[/tex]
[tex][\frac{d^2f}{dxdy} ]^2 = (4*x^3*2*y)^2 = 64*x^6*y^2[/tex]
Then, the equation to see if the points are saddle points or not are:
[tex](12*x^2*y^2)*(2*x^4) - 64*x^6*y^2 < 0[/tex]
In any of the previous found points (the ones of the form (x, 0) and (0, y)) the above equation will be equal to zero, then none of these points is a saddle point. More than that, in the particular case where the above equation is equal to zero, the critical points can be either: A relative minimum, a relative maximum, or a saddle point (so we need more analysis to find it out)
But in this case is ratter simple, because both powers in f(x, y) are even, we can conclude that the function is even and symmetric about x= 0 and y = 0, and the function is also positive, so all the points:
(0, y) and (x, 0) are the minimum values that f(x, y) can take.
Then the critical points are relative minimums.
write the point-slope form of the equation of the line described.
1. through: (-2, 5), slope =6
2. passing through the following points:
x y
7 19
8 22
9 25
10 28
Answer:
6x - y + 17=0
Step-by-step explanation:
Given :-
The slope of the line is 6 and it passes through (-2,5) .And we need to find out the equation of the line. Using the point slope form. The point slope form of the line is ,
[tex]:\implies[/tex] m ( x - x1) = ( y - y1)
[tex]:\implies[/tex] 6( x -(-2)) = ( y -5)
[tex]:\implies[/tex] 6( x +2) = y -5
[tex]:\implies[/tex] 6x +12= y -5
[tex]:\implies[/tex] 6x - y +17=0
Hence the equation of the line is 6x - y +17=0Using graphing, what is the approximate solution of this equation?
Answer:
D. x ≈ 2.60
Step-by-step explanation:
After graphing both of these equations separately, we can see that they meet at a point of x = 2.59, therefore the answer to this question would be D. Both values also seem to meet at an x value of -0.548 but it is not an option in this question, probably because the y output value is close not the same for both equations. The graphs can be seen in the attached picture below.

Karmen is buying a new car. For the exterior, she can choose from three colors---black, gray, or white. For the interior, she can choose between beige and gray. She can also choose between a manual and an automatic transmission. If Karmen picks a car at random, what is the probability of picking a car that has a black exterior and a beige interior? What is the probability of picking a car with a beige interior and an automatic transmission?
Answer:
The probability of Karmen picking a car with a black exterior and a beige interior is
1/6. The probability of Karmen picking a car with a beige interior and an automatic transmission is
1/4.
Step-by-step explanation:
The number of possible outcomes from the tree diagram is 12.
Two of the possible outcomes are a car with a black exterior and a beige interior. The probability of Karmen picking a car with a black exterior and a beige interior is , or .
Three of the possible outcomes are a car with a beige interior and an automatic transmission. So, the probability of Karmen picking a car with a beige interior and an automatic transmission is , or .
