Answer
a) correct
b) (30, 100) would mean an area of 100 square feet is enclosed when the width is 30 feet. (Kristina's vertex coordinates are incorrect.)
Step-by-step explanation:
a) The derivation and expression for A(w) are correct
__
b) Kristina made a mistake in using her graphing calculator to find the vertex. The actual vertex is (27.5, 756.25). The coordinates of the vertex are (w, A(w)). The vertex (w, A(w)) means that the area of the enclosed space is A(w) when the width of the enclosure is w.
If Kristina's vertex coordinates were correct (which they are not), they would tell you the enclosed area is 100 square feet when the width of the enclosure is 30 feet.

A cylinder has a diameter of 6 cm and a height of 14 cm. What is the approximate volume of a cone with the same diameter and height
as the cylinder?
Answers
The approximate volume of a cone with the same diameter and height as the cylinder is 131.95 cm³.
How to calculate the volume of a cylinder?In Mathematics and Geometry, the volume of a cylinder can be calculated by using this formula:
Volume of a cylinder, V = πr²h
Where:
V represents the volume of a cylinder.h represents the height of a cylinder.r represents the radius of a cylinder.Radius = diameter/2 = 6/2 = 3 cm.
By substituting the given parameters into the volume of a cylinder formula, we have the following;
Volume of cylinder, V = π × 3² × 14
Volume of cylinder, V = π × 9 × 14
Volume of cylinder, V = 395.8 cm³.
For the volume of this cone, we have:
Volume of cone, V = 1/3 × πr²h
Volume of cone, V = 1/3 × 395.8
Volume of cone, V = 131.95 cm³.

8n - 2(n+5) = -3 + 6n
Answers
Answer:
No solution
Step-by-step explanation:
There are no values of n that make the equation true.
8n −2(n+5) = −3 + 6n
First Step: Simplify both sides of the equation
(Distribute) 8n + (-2)(n) + (-2)(5) = -3 + 62
8n + -2n + -10 = -3 + 6n
(Combine like terms) (8n + −2n) + (−10) = 6n − 3
6n + −10 = 6n − 3
6n − 10 = 6n − 3
Step 2: Subtract 6n from both sides
6n − 10 − 6n = 6n − 3 − 6n
-10 = -3
Step 3: Add 10 to both sides
-10 + 10 = -3 + 10

x = 8
Step-by-step explanation:
Recall that the interior angles of a triangle always add up to 180 degrees.
Therefore: 77 + 50 + 7X - 3 = 180, or:
77 + 7X - 3 = 130, or:
7x = 56
Dividing both sides by 7 yields x = 8
Kalani has run 4 1/5 miles in 2/3 an hour. If he continues to run at this rate, how many miles will he run in one hour?
Answers
Answer:
Kalani will run 6.3 miles OR 6 3/10 miles.
Step-by-step explanation:
So first step that I would do is make it easier to understand by converting the fraction to a whole number. 2/3 hour= 40 minutes.
So Kalani runs 4 1/5 miles in 40 minutes.
Then, we convert 4 1/5 to 4.2. Next, I would divide 4.2 by 2 to get how long he ran in 20 minutes. 4.2/2=2.1.
The final step is to add 2.1 and 4.2 and we get 6.3.
Extra step:
But if we need to turn it back into a fraction, it would be 6 3/10
Hope this helps :)
