Answer:
a^3 + b^3
Step-by-step explanation:
(a + b)(a^2-ab+b^2)
a(a^2 -ab +b^2) +b(a^2-ab+b^2)
a^3 - a^2b +ab^2 + ba^2 -ab^2 +b^3
a^3 -a^2b +a^2b ab^2-ab^2 + b^3
final answer
a^3 + b^3
Its late but the answer is a^2+2ab+b^2-c^2! I hope this helps :) I was wrong the answer above is right!

Surface Area
6. Answer the question above (use 3.14 for pi):
Preface: We know that the radius of the cylinder is 2 inches and the height is 7 inches. Using the surface area formula (for a cylindrical figure), which has been provided below, we can, through calculations, figure out that the surface area of the cylinder is...
Formula: A = 2π × r × h + 2πr2= 2πr (h + r)
Variables: The "A" is the answer; "R" represents the radius and the "H" is the variable for the height of the cylinder. For the purpose of this question, we'll substitute 3.14 for pi (π).
Surface Area ≈ 113.1, or if you want the exact solution: 113.09734.

Identify the domain and range of each function
Answer:
Does this help I hope it does :D
How to find the domain and range of a function?
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

A 180 pound weight is supported by two ropes each at 30 degrees, as shown in the figure. Find the tension in each rope.
Answer:
= 41.32N
To find N amount
You find the kg weight then times it by 10 then divide that amount by 1/2
So that 180pounds = 81.6466 x 10kg
x10 = 816.466
81.6466 / 2 = 40.8233
sin(30) = 40.8233/T
T = 40.8233/sin (30) = N / sin(30) = Tension = calculator = -41.3178070464 = 41.32 N
Please find the area of the trapezoids.
By the way, the answer is NOT 10.5.
Answer:
42 square units
Step-by-step explanation:
Hello There!
The area of a trapezoid can be found using this formula
[tex]a = \frac{a + b}{2} h[/tex]
where a and b are bases and h is height
if you look at the graph we can see that the lines are counting by 2 units
knowing this we want to find the dimensions
the shown trapezoid has the following dimensions
a =2*2 or 4
b=5*2 or 10
h=3*2 or 6
having found this information we then plug it into the formula
[tex]a = \frac{4+ 10}{2} 6 \\ 4 + 10 = 14 \\ \frac{14}{2} = 7 \\ 7 \times 6 = 42[/tex]
so we can conclude that the area of the trapezoid is 42 square units

Answer:
10x^2-x-24
Step-by-step explanation:
Step-by-step explanation:
First, you have to expand the expression.
[tex](2x + 3)(5x - 8) \\ = (2x)(5x) + (2x)( - 8) + (3)(5x) + (3)( - 8) \\ = 10 {x}^{2} + ( - 16x) + 15x + ( - 24) \\ = 10 {x}^{2} - 16x + 15x - 24 \\ = 10 {x}^{2} - x - 24[/tex]
50 POINTS: Please help thank you so much!! (Image attached) The polygons are similar. Find the values of the variables.
I know from the answer key that the answers are x=
3 \sqrt{10}310
and y=
2 \sqrt{10}210
but I'm not sure how to get there...
Answer:
x = 3/5√10
y = 2√10
Step-by-step explanation:
using the Pythagorean theorem:
y² = 7² - 3² = 49 - 9
y² = 40
y = 2√10
3/4.5 = y/5x
4.5y = 15x
substitute for y:
4.5(2√10) = 15x
15x = 9√10
divide both sides of the equation by 15:
x = (9√10)/15 = 3/5√10
Show how to use substitution or elimination to solve the following system of equations. Write your solution as an ordered pair:
7x + y = 5 , 7x + y = -2
( , )
And please tell me if you used substitution or elimination. TYSM
Answer:
x=.5, y=-5.5
Step-by-step explanation:
7x+y=5, 7x+y=-2
Simplifing 7x+y=5 first
7x+y=5
y=-7x+5
Next, 7x+y=-2
7x+y=-2
y=-7x-2
Plugging in -7x+5 into y
-7x+5=-7x-2
-14x=-7
x=.5
Plugging .5 into y=-7x-2
y=-7(.5)-2
y=-3.5-2
y=-5.5
I used substitution if your couldn't tell
Hope it helps!

Consider △ABC. Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse A B is 13, the length of B C is 12, and the length of A C is 5. What are the angles that make the trigonometric statements true? sin( ) = cos(B) sin(B) = cos( )
Answer:
22.62°
Step-by-step explanation:
Considering △ABC. If angle B C A is a right angle, then;
m<BCA = 90 degrees
Given also
AB = 13
BC = 12
AC = 5.
According to SOH, CAH TOA;
Sin <B = AC/AB
Cos <B = BC/AB
Substitute the given values
Sin B = 5/13
B = arcsin(5/13)
B = 22.62
Cos B = 12/13
B = arccos (12/13)
B =22.62
Hence the angles that make sinB = cosB is 22.62°
Answer:
sin(A)=cos(B)
sin(B)=cos(A)

Roberto orders 13 quarts of special BBQ sauce. It costs him a total of $206.57. write an equation that can be used to find how much each quart cost. solve the equation
9514 1404 393
Answer:
13c = 206.57
Step-by-step explanation:
If c is the cost of 1 quart of sauce, then 13c is the cost of 13 quarts. We are told that is $206.57, so the equation is ...
13c = $206.57
__
You may be required to leave the dollar sign out of the equation. If you leave it in, then the answer comes with its own units (dollars).
c = $206.57/13 = $15.89

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)
Answer:
78.8 %
Step-by-step explanation:
From the question,
Area of the square = L²
A = L²
Where L = Length of the square.
From the diagram,
L = 4 in
Therefore,
A = 4²
A = 16 in².
Also,
Area of the circle (A') = πr²
Where r = radius of the circle.
Given: r = 2 in
Therefore,
A' = 22/7(2²)
A = 12.6 in²
Hence,
The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A
Pr = 12.6/16
Pr = 0.7875
Pr(%) = 78.75
Pr(%) = 78.8 %
Find the area of each regular polygon. Round your answer to the nearest tenth if necessary
Answer:
Step-by-step explanation:
13). Area of a square = (Side)²
= (BC)²
Since, diagonals of a square bisect each other at 90°,
ΔBOC is a right triangle.
By applying Pythagoras theorem in the given triangle,
BC² = OB² + OC²
BC² = 2(OB)²
BC² = 2(7√2)²
BC = [tex]\sqrt{196}[/tex]
Area of square ABCD = (BC)²
= (√196)²
= 196 units²
14). Measure of interior angles of the regular hexagon = 120°
Area of the regular hexagon = [tex]\frac{3\sqrt{3}}{2}(\text{side})^2[/tex]
From the given picture,
m∠BAC = m∠ABC = m∠ACB = 60°
Therefore, ΔABC is an isosceles triangle.
And all sides of this triangle will be equal in measure.
AB = AC = BC = 9 units
Area of the given regular hexagon = [tex]\frac{3\sqrt{3}}{2}(9)^2[/tex]
= 210.44 square units
≈ 210.4 square units
