An inverted pyramid is being filled with water at a constant rate of 70 cubic
centimeters per second. The pyramid, at the top, has the shape of a square
with sides of length 6 cm, and the height is 13 cm.
Find the rate at which the water level is rising when the water level is 3 cm.
cm/sec
Answers
Rates of change are the change of a quantity over another.
The rate of change in height of the water level is 36.51 cm per second.
Let the length of the top square be s, and the height be h.
The volume of the pyramid is:
[tex]\mathbf{V = \frac{1}{3}s^2h}[/tex]
At time t, we have:
[tex]\mathbf{V = \frac{1}{3}s(t)^2h(t)}[/tex]
The relationship between the side length and height is:
[tex]\mathbf{s : h=6 : 13}[/tex]
Express as fractions
[tex]\mathbf{\frac{s }{ h}=\frac{6 }{ 13}}[/tex]
Make s the subject
[tex]\mathbf{s=\frac{6 }{ 13}h}[/tex]
So, we have:
[tex]\mathbf{V = \frac{1}{3}s^2(t)h(t)}[/tex]
[tex]\mathbf{V = \frac{1}{3} \times (\frac{6 }{ 13}h(t))^2 \times h(t)}[/tex]
[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h(t)}[/tex]
[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^3(t)}[/tex]
Differentiate
[tex]\mathbf{V'(t) =3 \times \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h'(t)}[/tex]
[tex]\mathbf{V'(t) =\frac{36}{ 169}h^2(t) \times h'(t)}[/tex]
Make h'(t) the subject
[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex]
The water level rises constantly at 70 cm^3/s, and the water level is 3 cm.
So, we have:
[tex]\mathbf{V'(t) = 70}[/tex]
[tex]\mathbf{h(t) = 3}[/tex]
[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex] becomes
[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 3^2}}[/tex]
[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 9}}[/tex]
[tex]\mathbf{h'(t) = 36.51}[/tex]
Hence, the rate of change in height of the water level is 36.51 cm per second.

What is the median for the data shown below?
S= [110, 105, 126, 65, 134, 102, 78, 80, 119, 67, 88]
Answers
Answer:
102
Step-by-step explanation:
The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:
65 , 67 , 78 , 80 , 88 , 102 , 105 , 110 ,119 , 126 , 134
Since there is an odd number of data values in this data set, there is only one middle number. With 11 data values, the middle number is the data value at position 6. Therefore, the median is 102.
Answer:
102
Step-by-step explanation:
1. The median is the quantity that's in the middle of a data set.
2. First, we have to arrange the given data set from least to greatest:
65, 67, 78, 80, 88, 102, 105, 110, 119, 126, 1343. Now, when we try and locate the middle number, we can see that the number is 102.
Therefore, the median is 102.

The volume of a rectangular prism box can be represented by the function V(x) = 2x3 + 5x2 − 3x. If the height of the box is x cm, which of the following can represent the length and width of the container?
2x + 1 and x + 3
2x + 1 and x − 3
2x − 1 and x + 3
2x − 1 and x − 3
Answers
The factors which can represent the length and width of the container are; 2x − 1 and x + 3.
The Volume of a rectangular prism is a three-dimensional quantity and is the product of its length, width and height.
In essence;
Volume = l × w × h.However, V = 2x3 + 5x2 − 3x and height, h = x.
Therefore; V/h = l × w
l × w = (2x³ + 5x² - 3x)/xl × w = 2x² + 5x -3.l × w = (2x − 1) (x + 3)Consequently, the factors which can represent the length and width of the container are; 2x − 1 and x + 3.

A successful basketball player has a height of 6 feet 4 inches, or 193 cm. Based on statistics from a data set, his height converts to the z score of 2.66. How many standard deviations is his height above the mean?
Answers
Answer: 2.66 standard deviations above the mean
Explanation:
The z score directly determines how far we are from the mean. For positive z values, we are above the mean, while negative z values are below the mean.
The mean itself is z = 0
The absolute value of the z score is the distance from the score to 0. So having a z score of z = 2.66 means we are 2.66 standard deviations above the mean. Something like z = -2 means we are 2 standard deviations below the mean.
PLZ HELP WITH NUMBER 4 AND 5
Answers
Answer:
Question 4: 70 degrees
Question 5: 150 degrees
Step-by-step explanation:
Question 4:
The shape is a polygon therefore we need to first find the sum of the angle. The formula is: (number of sides - 2) * 180
Rewrite: (5 - 2) * 180 = 540
To get the answer we add all angles together which is:
135 + 120 + 80 + 135 = 470
Minus to get the last angle:
540 - 470 = 70 degrees
So the answer is 70 degrees:
x = 70 degrees
Question 5:
Again the type of shape is an polygon so first we need to find the sum of the angle.
(6 - 2) * 180 = 720
Next add up all the angles together. The square boxes mean the angle is a right angle. So we can just add 90 degrees for every box you see.
90 + 90 + 120 + 120 = 420
Minus the answer with the sum of the total angle to get the missing value:
720 - 420 = 300 degrees
Next since there are two x, and they are at the same position they are the same value so we can just divide and get the answer.
300 / 2 = 150 degrees
Therefore the answer for both x are 150 degrees:
x = 150 degrees.
