how do you find volume of a octagonal prism?
Answer:
V=2(1+2)a2h
Step-by-step explanation:
Final answer:
To calculate the volume of an octagonal prism, find the area of the base using the formula A = 2(1 + √2)s² for a regular octagon, then multiply by the prism's height. Ensure all measurements are in the same units.
Explanation:
To find the volume of an octagonal prism, you need to calculate the area of the base octagon and then multiply it by the height of the prism. The formula for the area of a regular octagon (assuming all sides, s, are equal) is [tex]A = 2(1 + \sqrt{2} )s^2[/tex], where s is the length of one side. To find the volume, V, you then multiply this area by the height, h, of the prism: V = A*h = [tex]2(1 + \sqrt{2} )s^2*h[/tex]. It's important to ensure that all measurements are in the same units to get the volume in cubic units (e.g., cubic centimeters, cubic meters).

Marisol is solving the equation 6(x+3)=21. Find her mistake and correct it.
Answer:
x = 1/2, See Explanation Below
Explanation:
When you solve the equation, you have to take out the 6 first. The mistake is that you Marisol subtracted from 3 directly instead of factoring the x and the 3 out. Below is what you are supposed to do in order to get the right solution.
Step-by-step for Equation:
6(x+3) = 21
6x + 18 = 21
6x = 21 - 18
6x = 3
x = 3/6
x = 1/2

What is the perimeter of the isosceles triangle shown below?
A) 27 units
B) 22 units
C) 32 units
D) 24 units
The perimeter of the isosceles triangle is C) 32 units.
Step-by-step explanation:
Step 1; First, we plot the three ends of the triangle. Assume the bottom left is A, the bottom right is B and the top end is C. The coordinates are;
A = (-6, -2), B = (6, -2) and = C (0, 6). A triangle's perimeter is the sum of its three side lengths. So we need to determine the side lengths of the given sides.
Step 2; To find the distance between A (-6, -2) and B (6, -2), we use the formula
Distance = √ (x2 - x1)² + (y2 - y1)².
Distance between (-6, -2) and (6, -2) where (-6, -2) is (x1, y1) and (6, -2) is (x2, y2).
Distance = √ (6 - (-6))² + (2 - (-2))² = √ 12² + 0² = √12² = 12 units.
Step 3; To find the distance between C (0, 6) and B (6, -2), we use the formula
Distance = √ (x2 - x1)² + (y2 - y1)².
Distance between (0, 6) and (6, -2) where (0, 6) is (x1, y1) and (6, -2) is (x2, y2).
Distance = √ (6 - 0)² + (-2 - 6)² = √ 6² + 8² = √36 + 64 =√100 = 10 units.
Step 4; To find the distance between C (0, 6) and A (-6, -2), we use the formula
Distance = √ (x2 - x1)² + (y2 - y1)².
Distance between (0, 6) and (-6, -2) where (0, 6) is (x1, y1) and (-6, -2) is (x2, y2).
Distance = √ (-6 - 0)² + (-2 - 6)² = √ 6² + 8² = √36 + 64 =√100 = 10 units.
Step 5; The perimeter of the triangle = 12 + 10 + 10 = 32 units, which is option C.

given h(x) = 4x + 3, find h(-1)
Answer:
-1
Step-by-step explanation:
4x-1=-4
-4+3=-1
The value of h(-1) is -1 after plugging the value of x = -1 in the function h(x) = 4x + 3 the answer is -1.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function h(x) = 4x + 3
Plug x = -1 in the above function:
h(-1) = 4(-1) + 3
h(-1) = -4 + 3
h(-1) = -1
The linear function can be defined as the relation between two variables, if we plot the graph of the linear function we will get a straight line.
If in the linear function, one variable is present, then the function is known as the linear function in one variable.
Thus, the value of h(-1) is -1 after plugging the value of x = -1 in the function h(x) = 4x + 3 the answer is -1.

Find an equation in slope-intercept form of the line that has slope 2 and passes through point A(-8, 7)
Answer:
y = 2x + 23
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (- 8, 7) into the partial equation
7 = - 16 + c ⇒ c = 7 + 16 = 23
y = 2x + 23 ← equation of line
Answer:
y=mx+c
y=2x+c
Y intercept(c) 23 - to find y we have to input the values
7=2*-8+c
7=-16+c
23=c

2. Doug paid $39.95 for dinner. He left a 15% tip for the server. Which of the following is closest to
the tip left by Doug? *
Answer:
$5.99
Step-by-step explanation:
In this problem, Doug paid the following amount for the dinner:
[tex]p=\$39.95[/tex]
He also left a 15% tip.
Here we want to calculate what is the amount correspondant to the tip.
In order to find this value, we have to calculate the 15% of the value of the dinner, therefore we want to find
the 15% of 39.95$
The percentage (15%) can be rewritten as fraction:
[tex]15\% =\frac{15}{100}[/tex]
Therefore, the amount of the tip is
[tex]t=\frac{15}{100}p[/tex]
And substituting p, we find:
[tex]t=\frac{15}{100}(\$39.95)=\$5.99[/tex]
So, the tip is $5.99.
Answer: 5.99
Step-by-step explanation:
Change % to decimal
Then multiply
15% =.15
39.95 x .15 = 5.99

4.2 Factoring x2 - 2x + 1
The first term is, x2 its coefficient is 1 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 1 • 1 = 1
Step-2 : Find two factors of 1 whose sum equals the coefficient of the middle term, which is -2 .
-1 + -1 = -2 That's it

x2 - 1x - 1x - 1
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-1)
Add up the last 2 terms, pulling out common factors :

Step-5 : Add up the four terms of step 4 :
(x-1) • (x-1)
Which is the desired factorization
Multiplying Exponential Expressions :
4.3 Multiply (x-1) by (x-1)
The rule says : To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (x-1) and the exponents are :
1 , as (x-1) is the same number as (x-1)1
and 1 , as (x-1) is the same number as (x-1)1
The product is therefore, (x-1)(1+1) = (x-1)2
Final result :

Answer:
3
Step-by-step explanation:
⇒15x-20=5y
⇒(15x-20)/5=y
⇒3x
The rate of change of the function is 3
m = 3how to find the rate of change of the functionTo find the rate of change of the function 15x - 5y = 20, we need to solve for y in terms of x and then determine the coefficient of x, which represents the rate of change.
Let's solve the equation for y:
15x - 5y = 20
Subtract 15x from both sides:
-5y = -15x + 20
Divide both sides by -5:
y = (15/5)x - 4
Simplifying the equation:
y = 3x - 4
Now we can observe that the coefficient of x is 3. Therefore, the rate of change of the function is 3. This means that for every unit increase in x, the corresponding y-value increases by 3.

What is s in 2m+4s=16 if m=-2
Answer:

Step-by-step explanation:
2m + 4s = 16
Step 1: Plug in -2 for m
2(-2) + 4s = 16
-4 + 4s = 16
Step 2: Solve for s
-4 + 4s + 4 = 16 + 4
4s / 4 = 20 / 4
s = 5
Answer: s = 5
Answer:
s= 5
Step-by-step explanation:
s= 5
m= - 2
2m + 4s= 16
Replace the m with the value it is in brackets. Remember brackets mean to multiply.
2(-2) + 4s= 16
-4 + 4s= 16
Carry over the -4 and make s the subject.
4s= 16 - - 4
4s= 16 + 4
4s= 20
s= 20/4
s= 5
Therefore s= 5
To check if the answer was correct, replace the s and m with the value it is in brackets. s= 5; m= 2
2(-2) + 4(5)= 16
-4 + 20 = 16
Therefore s= 5 and the answer is correct!
