Explain how calculating the surface area of a prism differs from a pyramid.
Answer:
To find the surface area of a prism, find the area of a base and double it since the areas of the two bases are always equal. Then find the area of each side face, and add to the area of the bases. A pyramid has one base and triangular sides.

Answer:
1/2
Step-by-step explanation:
The Rational Root Theorem says that any rational root has
1. a numerator that is a factor of the constant term
2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)
Numerator: [tex]\pm 1[/tex]
Denominator: [tex]\pm 2[/tex]
That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]
Try them both by plugging them into the polynomial.
[tex]2\left(\frac{1}{2}\right)^3 + 3\left(\frac{1}{2}\right)^2 -1= \frac{1}{4}+\frac{3}{4}-1 =0[/tex]

find the indefinite integral ∫((x^2)/(4x^3+9)) dx
Answer:
[tex] \displaystyle \frac{1}{12} \ln( |{4x}^{ 3} + 9|) + \rm C[/tex]
Step-by-step explanation:
we would like to integrate the following indefinite integral:
[tex] \displaystyle \int \frac{ {x}^{2} }{4 {x}^{3} + 9} dx[/tex]
in order to integrate it we can consider using u-substitution also known as the reverse chain rule and integration by substitution as well
we know that we can use u-substitution if the integral is in the following form
[tex] \displaystyle \int f(g(x))g'(x)dx[/tex]
since our Integral is very close to the form we can use it
let our u and du be 4x³+9 and 12x²dx so that we can transform the Integral
as we don't have 12x² we need a little bit rearrangement
multiply both Integral and integrand by 1/12 and 12:
[tex] \displaystyle \frac{1}{12} \int \frac{ 12{x}^{2} }{4 {x}^{3} + 9} dx[/tex]
apply substitution:
[tex] \displaystyle \frac{1}{12} \int \frac{ 1}{u} du[/tex]
recall Integration rule:
[tex] \displaystyle \frac{1}{12} \ln(|u|) [/tex]
back-substitute:
[tex] \displaystyle \frac{1}{12} \ln( |{4x}^{ 3} + 9|) [/tex]
finally we of course have to add constant of integration:
[tex] \displaystyle \frac{1}{12} \ln( |{4x}^{ 3} + 9|) + \rm C[/tex]
and we are done!

Samir bought 3 pounds of cement to repair the cracks in his sidewalk.
Each crack needs to be filled with 2 ounces of cement.
Answer:
24 cracks will be filled
Step-by-step explanation:
Here, the first question asks how to convert 3 pounds to ounces.
we can do this using a mathematical approach. To convert pounds to ounces, we need to know that there are 16 ounces in a pound. so to convert pounds to ounces, we just need to multiply the number of pounds we have by 16 to get the equivalent number of ounces.
The second question asks to give the number of cracks that be repaired.
From the question, we were made to know that each of the cracks would eat up 2 pounds of cement to be filled.
Let’s calculate the amount of cement we have. That would be 3 * 16 = 48 ounces of cement.
The amount of cracks to be filled is thus 48 ounces/2 ounces = 24 cracks

16. A roller rink floor is show below. Each end has a semicircle. What is the area? Use = 3.14
20 m
Answer:
714m^2
Step-by-step explanation:
So, as we said in the comments, since they didn't give the radius, we have to assume the center is a square. That means the area of the center part is 20m x 20m, and the diameter of the circular ends is 20m as well.
Area of center: 20 x 20 = 400m^2
Area of ends:
Area = (pi)(r)^2
The radius = 1/2 the diameter = 10m
Area = (3.14)(10)(10)
Area = 3.14 x 100 = 314m^2
Now, if it only had one semicircle on the end like your previous question, we'd have to divide this answer by 2, but the circular area we just calculated covers both ends, so the total area = the square center + the circular area
400 + 314 = 714m^2

The sigma symbol means that you have to add them all up so the sum is 6. Therefore,
(6)^2 = 36
Answer:
36
Step-by-step explanation:
Sum the terms (x - 2) for x = 2 to 5 then square the result
[ (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) ]²
= ( 0 + 1 + 2 + 3 )²
= (6)²
= 36

Omar, Hala and Lujain got paid a total of $240 for cleaning neighborhood cars. They split the money in the ratio of 5: 9: 10. How much money did Omar earn?
Answer:
Total amount Omar earn = $120
Step-by-step explanation:
Given:
Total amount Omar, Hala and Lujain got paid = $240
Ratio of money Omar, Hala and Lujain got paid = 5:9:10
Find:
Total amount Omar earn
Computation:
Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]
Total amount Omar earn = [240][5 / (5+9+10)]
Total amount Omar earn = [240][5 / (24)]
Total amount Omar earn = [24][5]
Total amount Omar earn = $120

A.434.9 in^3
B.23.1 in^3
C.217.4 in3
D.54.3 in3
Answer:
The awnswer is D. 54.3in^3
Step-by-step explanation:
The amount of snow that can be placed on this globe will be 23.1 inch³.
What is the volume of the globe?
Globe is a spherical 3d element that has a radius let R then the volume of that sphere will be 4/3 π R³.
Given a globe wide 4.7 inches means it is the diameter of the globe.
The radius of the globe = dia/2.
Radius = 2.35 inch.
Volume of globe(amount of snow) = 4/3 π (2.35)³= 23.1 inch³
so the amount of snow needed will be 23.1 inch³.

Answer:
Step-by-step explanation:
Problem 1
g(-23) = 3
g(0) = 5
2 = g(10)
1 = g(34)
Problem 2
No, because g(x) = f(-x). For g(x) to inverse of f(x), g(f(x)) = x
Problem 3
tan(50) = 1.19
Height of statue = 250*1.19 - 150
= 147.9 ft
Problem 4
cosθ = 9/12
θ = 41.41 deg.
Answer:
Step-by-step explanation:
g(x) is inverse of f(x)
so g(f(x))=x
g(-23)=3
g(0)=5
g(10)=2
g((34)=1
no, it is an inverse
4 inverse fn, g(r(x))=x
but here g(x)=r(-x)
so g(r(x))=r(-r(x)) n NOT =x
pedestal + statue = 250*tan(50degree) = 297.94
statue ht = 297.94-150 = 147.94 ft
cos(theta) = 9/12
theta = 41.41 deg.

Step-by-step explanation:
because The graph of which quadratic function has roots of 7 and 3 and passes through (2, 10), so therefore its C
The equation f(x) = 2x² -20x +42 and the function has minimum at x=5 which is f(5) = -8 option (C) is correct.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
Part A)
The quadratic function has roots of 7 and 3
f(x) = (x - 7)(x - 3)
f(x) = x² -3x -7x +21
f(x) = x² -10x +21
Multiply by:
f(x) = 2x² -20x +42
Plug (2, 10)
10 = 8 - 40 +42 = 10
Part B) From the graph, the function has minimum at x = 5
f(5) = -8
Thus, the equation f(x) = 2x² -20x +42 and the function has minimum at x=5 which is f(5) = -8
