Find The value of H:
S=2πr(r+h)
Answers
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
\(\\ \rm\Rrightarrow S=2\pir(r+h)\)
\(\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}\)
\(\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r\)
\(\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}\)

Question: What is the AREA of this shape
(and pls include steps)
Answers
Step-by-step explanation:
first off: write the formula that you would be using, which in my case would be
A = B x H
the B stands for base, and the H stands for height
the base of the shape would be 14.3 in
while the height is the dotted line in the middle (which would be 14.4 in)
to find the answer you would write it like this:
A = B x H = 14.3in x 14.4in
= (conversion to other form of measurement if necessary)
= 205.92 in
(answer may be wrong as it was calculated with calculator app)
The area formulas for each shape are:
rectangle: A=b*h
triangle: A=(1/2)b*h
First, you can start by noticing that the base for both the triangle and rectangle is given, being 14.3 inches.

How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.The slope and the intercept for the function in this problem are given as follows:
Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.Hence, the predicted cost for a month with temperature of 25ºF is given as follows:
y = -1.22(25) + 96.20 = $65.70.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.
