Answer:
Step-by-step explanation:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
Given the following data;
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.
Substituting into the equation, we have;
Volume = 301.6 cm³ (to 1d.p)
b. The curved surface area of the cone
Where;
CSA is the curved surface area of the cone.
r is the radius of the base of the cone.
l is the curved length of the cone.
Substituting into the equation, we have;
CSA = 188.5 cm² (to 1d.p)

The area of a rectangle is 72 sq units. One side length is 9 units. What is the other side length
Answers
Based on the area of the rectangle and the length of one side, the length of the other side is 8 units
The area of a rectangle is calculated as:
Area = Length x Width
The length is already given so the width is:
72 = 9 x Width
Width = 72 / 9
Width = 8 units
In conclusion, the other side length is 8 units.

The length of other side of rectangle is 8 unit.
Step-by-step explanation:
Given :

I need help determineing the next number.?!
Answers
Answer:
The next number is -12 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ The pattern is 2,916, -972, 324, -108, 36, ....
→ All the given numbers are divisible by 3 because the sum of
the digits of each number can divide by 3
2+9+1+6 = 18 → multiple of 39+7+2 = 18 → multiple of 33+2+4 = 9 → multiple of 31+0+8 = 9 → multiple of 33+6 = 9 → multiple of 3∵ The pattern has positive and negative numbers
∴ Each next term = the previous term ÷ -3
→ Let us do that to find the missing number
∵ 2916 ÷ -3 = -972
∵ -972 ÷ -3 = 324
∵ 324 ÷ -3 = -108
∵ -108 ÷ -3 = 36
→ Find the next number by divide 36 by -3
∵ 36 ÷ -3 = -12
∴ The next number is -12

A pencil costs $0.25 more than an eraser. If the cost of eight pencils is $6.80, what is the cost of one eraser?
Answers
Answer:
A single pencil costs $0.85 and a single eraser costs $0.60
Answer: The cost of one eraser is $0.6
Step-by-step explanation:
When solving this problem, it's best to set up a system of equations. Let pencil = p and eraser = e.
p = $0.25 + e
8p = $6.80
Now, we can use the second equation to solve for p by dividing both sides by 8. 6.8/8 = 0.85. Therefore, p = $0.85.
Then, use the value of p to find e by plugging the value of p we just found back into the first equation we wrote. Doing so, we get $0.85 = $0.25 + e. To solve for e, we must subtract 0.25 from both sides, giving use 0.85-0.25 = 0.6
Therefore e = $0.6, so the cost of one eraser is $0.6 or 60 cents.

You need to know special right triangles
This is a 30,60, 90 triangle
We automatically know becuase theres. Right angle (90) and a 60 degree angle
now the formula is the smallest side is (n) {I’m using N becuase theres already an X) or in this case, 6
The hypotenuse, the one directly above the 2nd biggest side, or the diagnoal side is 2n or (12). Now we know what X is in this situation which is 12. So that narrows it to 2 answers
Now the side on the bottom of the hypotenuse, the second biggest side is used in the formula N[tex]\sqrt{3}[/tex]. So we know what N is in the beginning, 6 so we just plug that in and well get C. Attached is a photo on q 30, 60, 90 special right triangle

Here, we want to get the range given the domain
we simply make a substitution of the domain in the equation so as to get the range
So let us substitute the value of the domain one after the other
f(3) is 3-9 = -6
f(-3) = -3-9 = -12

a. The graph represents a function because it has a positive slope.
b. The graph represents a function because it passes the vertical line test.
c. The graph does not represent a function because it does not pass through (0,0).
d. The graph does not represent a function because it does not pass the horizontal line test.
Answers
The graph represents a function because it passes the vertical line test thus the best option B.
What is graph?The graph is "pictorial representation or diagram that represents data or value in an organized manner".
What is vertical line test?
If "all vertical line intersect the curve at most once, then the curve represents function" is called vertical line test for function.
According to the question,
In this graph, for one value of x, the graph has one value for y.
Hence, the graph represents a function because it passes the vertical line test thus the best option B.

Find the inverse of “f” algebraically, please!
Answers
Answer: [tex]f^{-1}(x) = -\sqrt{36-x^2}[/tex]
====================================================
Here are the steps to find the inverse
[tex]f(x) = \sqrt{36-x^2}\\\\y = \sqrt{36-x^2}\\\\x = \sqrt{36-y^2} \ \text{ swap x and y; solve for y}\\\\x^2 = 36-y^2\\\\x^2+y^2 = 36\\\\y^2 = 36-x^2\\\\y = \sqrt{36-x^2}\\\\f^{-1}(x) = \sqrt{36-x^2}\\\\[/tex]
Now this would be the answer if our original domain was [tex]0 \le x \le 6[/tex]
However, that's not the case and instead our domain is [tex]-6 \le x \le 0[/tex]
Reflecting any (x,y) point in this domain restriction, over the the line y = x, will have us land on a point with a negative y value. This is because the inverse will swap the x and y values.
Therefore, the inverse function must ultimately be negative.
Currently [tex]f^{-1}(x) = \sqrt{36-x^2}[/tex] is positive since the result of any square root is never negative.
To fix this, we stick a negative out front to get the final answer being [tex]f^{-1}(x) = -\sqrt{36-x^2}[/tex]
