"A rectangle has a height of 5 cm and its base is increasing at a rate" of 3/2 cm/min. When its area is 60 cm2, at what rate is the diagonal of the rectangle increasing?
The rate at which the diagonal of the rectangle is increasing is 18/13 cm/min.
To find the rate at which the diagonal of the rectangle is increasing, we can use the relationship between the sides of the rectangle, its area, and the diagonal.
Given that Height of the rectangle (h) = 5 cm
The rate at which the base is increasing (db/dt) = 3/2 cm/min
Area of the rectangle (A) = 60 cm²
We can determine the base (b) using the formula for the area of a rectangle:
A = b x h
60 = b x 5
b = 12 cm
Next, the Pythagorean theorem:
d² = b² + h²
d² = 12² + 5²
d² = 144 + 25
d² = 169
d = 13 cm
Now, to determine the rate at which the diagonal is increasing (dd/dt), we can differentiate the equation for the diagonal with respect to time:
d² = b² + h²
2d x (dd/dt) = 2b x (db/dt) + 0 x (dh/dt)
2d x (dd/dt) = 2b x (db/dt)
(dd/dt) = (b (db/dt)) / d
Substituting the known values:
(dd/dt) = (12 x (3/2)) / 13
(dd/dt) = 36/26
(dd/dt) = 18/13 cm/min
Therefore, the rate at which the diagonal of the rectangle is increasing is 18/13 cm/min.

The volume of a single layer in a rectangular prism is 9 cubic centimeters. There are 6 layers in the rectangular prism. What is the total volume, in cubic centimeters, of the rectangular prism?
Answer:
Total volume of the rectangular prism = 54 cubic centimeters
Step-by-step explanation:
Volume of a single layer in a rectangular prism = 9 cubic centimeters
There are 6 layers in the rectangular prism
What is the total volume, in cubic centimeters, of the rectangular prism?
Total volume of the rectangular prism = Volume of a single layer in the rectangular prism × number of layers in the prism
= 9 cubic centimeters × 6 layers
= 54 cubic centimeters
Total volume of the rectangular prism = 54 cubic centimeters

The air conditioning unit for marcus building has the shape of a cube and has a volume of 0.512 cubic meters.This air conditioner will be replaced with another cube-shaped unit with a volume of 1 cubic meter. By how much will the edge length of the air conditioner change?
Answer:
The edge length of the air conditioner changed by 0.2m
Step-by-step explanation:
The volume of a cube is S^3
The edge length of the former unit is cube root of 0.512 which is 0.8 m
The edge length of the new is cube root of 1 which is 1 m
The difference is 1-0.8 = 0.2 m
The winning time for the men's 400-meter race in each of the Olympic Games from 1976 to 1996 can be modeled by the equation y = −0.054x + 44.54 , where x is the number of years after 1976 and y is the winning time in seconds. If the relationship continues, which equation could be used to predict the winning time in the year 2020?
Answer:
D. y = −0.054(44) 44.54
Step-by-step explanation:
The difference in years from 1976 to 1996 is 20 years
But from 1976 to 2020 the years would be 44
So here put the value of x as 44
Therefore the equation that could be used for predict the winning time for the year 2020 is y = −0.054(44) 44.54
Hence, the correct option is d.

A community is building a new outdoor basketball court. The length of the court is twice the width.
Answer:
Step-by-step explanation:
The width of the basketball court is given by W(A) = √(A/2), and the length is given by L(A) = √(2A). These expressions allow you to calculate the width and length of the court for a given area A in square feet.
The problem states that the width of the basketball court (W) can be modeled by the equation:
W(A) = √(A/2)
where A is the area of the court in square feet.
Since the length (L) of the basketball court is twice the width (W), we can express it as:
L = 2W
Now, let's find the expression for the length (L) in terms of the area (A) of the court.
Step 1: Substitute the value of W from the given model into the expression for L:
L = 2 × √(A/2)
Step 2: Simplify the expression:
L = √(4A/2)
L = √(2A)
So, the expression for the length (L) of the basketball court in terms of its area (A) is given by L = √(2A).
To summarize, the width of the basketball court is given by W(A) = √(A/2), and the length is given by L(A) = √(2A). These expressions allow you to calculate the width and length of the court for a given area A in square feet.

Answer:
(5, 0)
Step-by-step explanation:
For the first line, we can isolate x by subtracting 5y on both sides.
x=5-5y.
Now we can use substitution on the second line!
-(5-5y)+6y=-5
= -5+5y+6y=-5
=-5+11y=-5

y=0
We subsitute y for the first line,

The equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2
How to determine the function g(x)?The equation of the function f(x) is given as:
f(x) = x^3
The function g(x) is shifted down by 2 units and shifted left by 3 units, to get the function g(x)
This means that:
g(x) = f(x + 3) - 2
So, we have:
g(x) = f(x + 3) - 2
Hence, the equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2

Ms. Raab and Ms. Levy both drink coffee in the
mornings.
Ms. Raab adds 1 more teaspoon to each cup of
coffee than Ms. Levy. Together, they both add 5
teaspoons of sugar to their coffees.
How many teaspoons of sugar does Ms. Raab add?
How many teaspoons does Ms. Levy add?
Set up an equation to show this, and then solve.
Answer:
Ms Levy = 2
Ms Rabb = 3
Step-by-step explanation:
Let :
Number of teaspoons taken by Ms Levy = x
Number of teaspoons taken by Ms Rabb = x + 1
Total number of teaspoons taken by both = 5
(Number of teaspoons taken by Ms Rabb + Number of teaspoons taken by Ms Levy) = total number of teaspoons taken
x + 1 + x = 5
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
Hence,
Number of teaspoons of sugar added by Ms Levy = x = 2
Number of teaspoons of sugar added by Ms Rabb = x + 1 = 2 + 1 = 3
A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of
the base of the speaker is 11 square inches.
What is the volume of the speaker in cubic inches?
Answer:
[tex]V=22\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
Height of a triangular pyramid = 6 inches
The area of the base of the speaker is 11 square inches
We need to find the volume of the speaker.
The formula for the volume of triangular pyramid is given by :
