Answer:
936 square units.
Step-by-step explanation:
Area formula of trapezoid: [tex]A=\frac{a+b}{2}h[/tex]
given information:
a = 40
b = 64
h = 18
plug them into the formula:
[tex]A=\frac{40+64}{2}\cdot 18[/tex]
[tex]A = 936[/tex]
Can yall get me the volume calculations for the 3 shapes? Thank you! | Geometry
Figure 1
Name = Coneh = 4 unitsd = 8Since the diameter is 8, this cuts in half to the radius of r = 4. Plug the given values into the cone volume formula below
V = (1/3)*pi*r^2*h
V = (1/3)*pi*(4)^2*4
V = (64/3)pi ..... exact volume in terms of pi
V = (64/3)*3.14
V = 66.98667 .... approximate volume when using pi = 3.14
========================================================
Figure 2
Name = cylinderh = 4d = 8 which cuts in half to r = 4V = volume of cylinder
V = pi*r^2*h
V = pi*4^2*4
V = 64pi ..... exact volume
V = 64*3.14
V = 200.96 .... approximate volume when using pi = 3.14
========================================================
Figure 3
Name = rectangular prismb = 32h* = 12h = 4b and h* are dimensions along the bottom face, aka floor
h is the height or vertical dimension of the 3D room
V = volume of rectangular prism = volume of 3D room
V = length*width*height
V = (b)(h*)(h)
V = (32)(12)(4)
V = 1536 is the exact volume
There is no approximate volume for this figure because the result above is an integer.
========================================================
Combining the figures
Adding up the volumes for figures 1 through 3 gets us
(64/3)pi + 64pi + 1536 = (256/3)pi + 1536
The exact total volume in terms of pi is (256/3)pi + 1536
If we used pi = 3.14, then it leads to
(256/3)pi + 1536 = (256/3)*3.14 + 1536 = 1803.94667
The approximate total volume of all three figures combined is roughly 1803.94667 cubic units

Pleaseee don’t answer if you don’t know, I need this really soon.
Step-by-step explanation:
a)
[tex]\sin^{2}x + \cos^{2}x = 1[/tex]
Dividing both sides by sin^2x, we get
[tex]1 + \frac{\cos^{2}x }{ \sin^{2}x} = \frac{1}{\sin^{2}x } [/tex]
The 2nd term on the LHS is simply cot^2x and the RHS is simply csc^2x
[tex]1 + \cot^{2}x = \csc^{2}x[/tex]
b)
[tex]2 \sin x = 1[/tex]
[tex] \sin x = \frac{1}{2} [/tex]
[tex]x = \sin^{ - 1} (\frac{1}{2}) = \frac{\pi}{6} [/tex]
You can also graph it to arrive at the solution.

Type the expression that results from the following series
of steps:
Start with x and multiply by itself.
Answer: x^2 (the ^ represents that the next number is an exponent)
Step-by-step explanation:
Any number squared (to the power of 2) is just itself multiplied by itself. Remember, multiplication is repeated addition and exponents are repeated multiplication.

QUESTION: A pentagon has angles that measure 110°, 90°, 80°, 115°, and v. What is v?
Answer:
145
Step-by-step explanation:
angles in a pentagon add up to equal 540
Hence, 110 + 90 + 80 + 115 + v = 540
( note that we just created an equation that we can use to solve for v )
We now solve for v using the equation created
110 + 90 + 80 + 115 + v = 540
step 1 combine like terms
110 + 90 + 80 + 115 = 395
we now have 395 + v = 540
step 2 subtract 395 from each side
540 - 395 = 145
395 - 395 cancels out
we're left with v = 145

Complete the missing parts of the table for the following function. y=7x
Answers: 49, 1, 49
Those values go in the blanks from left to right
=====================================================
Explanation:
The rule we use is x^(-k) = 1/(x^k)
That means if we're evaluating something like 7^(-1), then it's the same as 1/(7^1) = 1/7 which explains how x = -1 leads to y = 1/7.
Similarly, 7^(-2) = 1/(7^2) = 1/49 is the y value when x = -2. So you'll type 49 into the first box to fill in that missing denominator.
Raising any nonzero value to the zeroth power leads to 1. That rule is x^0 = 1 where x can be anything you want but it can't be zero. Therefore 7^0 = 1 goes in the second box.
Lastly, 7^2 = 7*7 = 49 will go in the third box.

a regular sheet of letter (printing) paper measrues 8.5 inches by 11 inches. you want to cut out squares from each corner that it may be folded up to produce an open - top box. What are the dimensions of the square cut outs that will result in a box of maximum volume
Answer:
The dimensions of the square, that will result in a box of maximum volume is a square with side length of approximately 1.585 inches
Step-by-step explanation:
The given dimension of the steel sheet are;
The width = 8.5 inches
The length = 11 inches
Let 'x' represent the side length of the squares cut out, we have;
The length of the box formed, l = 11 - 2·x
The width of the box formed, w = 8.5 - 2·x
The height of the box, h = x
The volume of the box, V = (11 - 2·x) × (8.5 - 2·x) × (x) = 4·x³ - 39·x² + 93.5·x
The maximum or minimum volume is found from dV/dx = 0 at max. or min.
dV/dx = d(4·x³ - 39·x² + 93.5·x)/dx = 12·x² - 78·x + 93.5 = 0
Which gives;
x = (78 ± √((-78)² - 4×12×93.5))/(2 ×12)
x = 4.915 or 1.585
When x = 4.915, V = 4 × 4.915³ - 39 × 4.915² + 93.5 × 4.915 = -7.65
When x = 1.585, V = 4 × 1.585³ - 39 × 1.585² + 93.5 × 1.585 = 66.15
Therefore, the local maximum occurs at x ≈ 1.585
Therefore, the dimensions of the square, 'x' that will result in a box of maximum volume is x ≈ 1.585 inches.

how to solve the median
Answer:
1.) Set the data set in the ascending order
2.) Start cancelling out numbers each side, like if u cancel out the first number, then cancel out the last as well.
3.) Keep doing the step 2 until u reach the middle most number.
4.) Sometimes there are 2 middle numbers left, in that case find their average (add both numbers together and divide the sum by 2) which would be ur middle most number.
