2) The area of my best friend's pool is 121ft2. What is the width of the pool if the length is 12ft?
Answer:
10.083333...ft
Step-by-step explanation:
length = 12ft
area = 121sqft
area = length * width
121sqft = 12ft * width
width = 121sqft / 12ft
[tex]width = 10\frac{1}{12}\mathrm{ft}[/tex]
width = 10.08(3)ft
Find the surface

triangular prism
using the net.
7 cm
5 cm
4 cm
6 cm
5 cm
The surface area of the triangular prism is 136 cm square.
How to find the surface area of a triangular prism?The surface area of a triangular prism can be found as follows;
Therefore,
surface area of a triangular prism = (perimeter of the triangle × height of prism) + (2 × base area)
Hence,
perimeter of the triangle = 5 + 5 + 6
perimeter of the triangle = 16 cm
height of prism = 7 cm
base area = 1 / 2 bh
base area = 1 / 2 × 4 × 6
base area = 24 / 2
base area = 12 cm²
Therefore,
surface area of a triangular prism = (16 × 7) + (2 × 12)
surface area of a triangular prism = 112 + 24
surface area of a triangular prism = 136 cm²

Identify slope from a graph
The mathematical definition of slope is very similar to our everyday one. In math, slope is used to describe the steepness and direction of lines. By just looking at the graph of a line, you can learn some things about its slope, especially relative to other lines graphed on the same coordinate plane. Consider the graphs of the three lines shown below:
You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope. Let’s look at an example.
EXAMPLE
Use the graph to find the slope of the line.
A line that crosses the points (2,1) and (6,3). A blue line labeled Rise goes up two units from the point (2,1). A red line labeled Run goes left from the point (6,3) so that it forms a triangle with the main line and the Rise line. A formula says slope equals rise over run.
Show Solution
This line will have a slope of

no matter which two points you pick on the line. Try measuring the slope from the origin,
(

, to the point
(

and the
run

. The slope is
rise
run

. It is the same!
Let’s look at another example.
EXAMPLE
Use the graph to find the slope of the two lines.
A graph showing two lines with their rise and run. The first line is drawn through the points (-2,1) and (-1,5). The rise goes up from the point (-2,1) to join with the run line that goes right to the point (-1,5). The second line is drawn through the points (-1,-2) and (3,-1). The rise goes up from the point (-1,-2) to join with the run to go right to the point (3,-1).
Show Solution
When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line,

Describe in words the transformations that map angle ABC to angle A'B' C'. Make sure that you add special details.
The translation rule that maps ABC to A'B'C' is (x, y) ⇒ (x + 3, y + 6)
What is transformation?Transformation is the movement of a point around the coordinate plane. Types of transformations are rotation, translation, reflection and dilation.
Translation is the movement of a point either up, down, left or right in the coordinate plane.
The translation rule that maps triangle ABC to angle A'B'C' is (x, y) ⇒ (x + 3, y + 6)

No Extraneous solution
The given equation is
( 7x + 6 ) ^ 1/2 - (9 + 4x ) ^ 1/2 = 0
We have to find the value of x
[tex]\sqrt{7x + 6}[/tex] = [tex]\sqrt{9 + 4x}[/tex]
Squaring both sides of the equation
[tex](\sqrt{ 7x + 6} )^{2}[/tex] = [tex](\sqrt{9 + 4x})^{2}[/tex]
7x + 6 = 9 +4x
3x = 3
x = 1
To know whether the value of x is the extraneous solution or not, put the value of x in the equation
[tex]\sqrt{7 * 1 + 6}[/tex] -[tex]\sqrt{ 9 + 4 * 1}[/tex] = 0
[tex]\sqrt{13}[/tex] - [tex]\sqrt{13}[/tex] =0

Find each product or quotient. 7√7 . 3√7
The given expression can be solved by determining the product of irrational numbers.
Irrational number is a real number that cannot be expressed as the quotient of two integers. If a square root of a number is not a perfect square root, then it is an irrational number.
In the given expression, there are two rational numbers 7 and 3 while two irrational numbers √7 and √7.
The integer 7 and 3 can be multiplied. Hence,
7√7*3√7=7*3*√7*√7=21*√7*√7
When multiplying terms in square root, √a*√b=√ab. Hence,
21*√7*√7=21√7*7
As square root of a number is the number multiplying itself i.e., √a*a=a
21√7*7= 21*7=147

The nature of the roots in the given quadratic equation (x - 3)² + (x - 4)² = 0 is; A: two rational roots
What are the roots of the Quadratic Equation?We are given the quadratic equation;
(x - 3)² + (x - 4)² = 0
Now, some of the rules in naming the roots are;
If b² – 4ac > 0, then the roots are real and unequal
If b² – 4ac = 0, then the roots are real and equal
If b² – 4ac < 0 then the roots are unequal and Imaginary
If b² – 4ac > 0 (is a perfect square), then the roots are real, rational and unequal
If b² – 4ac > 0 (is not a perfect square), then the roots are real, irrational and unequal
From the above rules and comparing to our given equations, it is clear that we have two rational roots which are x = 3 and x = 4.

The angle of ∠FEG is 58 degrees
How to find angles?The angle DEF is a right angle.
Therefore,
∠DEF = 90°
Hence,
∠FEG + ∠GED = ∠DEF
∠FEG = 5x - 22
∠GED = 2x
∠DEF = 5x - 22 + 2x
90 = 5x + 2x - 22
90 = 7x - 22
90 + 22 = 7x
112 = 7x
divide both sides by 7
x = 112 / 7
x = 16
∠FEG = 5x - 22
∠FEG = 5(16) - 22
∠FEG = 80 - 22

How many zeros does this 7.185629 x 10^2985 have?
Answer: 2979 Zeroes
Step-by-step explanation:
1. Figure out what 10^2985 is. (It's one followed by 2985 zeroes).
2. Using that knowledge, make 7.185629 a whole number. To do that, you need to multiply it by a number that has the same number of zeroes as it does to move the decimal place one by one to the right. In this case, it is 1,000,000, because it has 6 zeroes and you need to move the decimal point past 6 numbers (after 7 in 7.185629).
3. Subtract 2985 by 6, because you used 6 zeroes.
4. This gives you the answer 2979 zeroes because 2985 zeroes - 6 zeroes= 2979 zeroes.

Is y=e (x+7) a natural base exponential function?
We need to know about natural exponential function to solve the problem. The given function is a natural base exponential function.
An exponential function is a function in which x is an exponent. An exponential function has an exponential graph that keeps growing. A natural base exponential function is one where the base of the function is e which is a mathematical constant and is approximately equal to 2.71828. The inverse of a natural exponential function is a logarithmic function. An exponential function is of the form y=[tex]b^{x}[/tex] where b is the base, in a natural base exponential function, the b is replaced by e which means y=[tex]e^{x}[/tex]. In the given question y=[tex]e^{x+7}[/tex] is a natural base exponential function since the base is the natural base.
Therefore we found that the given function is a natural base exponential function.
