Answer:
x = 20 unitsStep-by-step explanation:
Given the right triangle with one side unknown
Use Pythagorean Theorem to find the value of x:
x² = 16² + 12²x² = 256 + 144x² = 400x = √400x = 20Question 6
Find the slope of the line that passes through the pair of points.
(-3, 2), (7, 2)
Answer:
Slope = 0
Step-by-step explanation:
Given the pair of points: (-3,2) (7,2)
Slope formula: y2-y1/x2-x1
2-2/7-(-3) = 0/10
0/10 = 0
What is the value of x?
Answer:
B
Step-by-step explanation:
Since UV is a tangent then ∠ WUV = 90°
WZ = WU = x - 1 ( both radii of the circle ) , then
WV = x - 1 + 2 = x + 1
Using Pythagoras' identity in the right triangle
WU² + UV² = WV² , that is
(x - 1)² + (2x - 4)² = (x + 1)² ← expand factors using FOIL
x² - 2x + 1 + 4x² - 16x + 16 = x² + 2x + 1
5x² - 18x + 17 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
4x² - 20x + 16 = 0 ← divide through by 4
x² - 5x + 4 = 0
(x - 1)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 4 = 0 ⇒ x = 4
But x ≠ 1 as radius x - 1 = 0
Thus x = 4 → B

Surface area question:
Answer:
190π (not part of the answer choices)
Step-by-step explanation:
The surface area of a cylinder can be found using the formula below:
[tex]SA=2\pi r^2+\pi dh[/tex] where [tex]r[/tex] is the radius of the base, [tex]d[/tex] is the diameter of the base and [tex]h[/tex] is the height of the cylinder.
Plug in the given values
[tex]SA=2\pi (\frac{10}{2}) ^2+\pi (10)(14)\\SA=2\pi (\frac{100}{4})+140\pi\\SA=2\pi (25)+140\pi\\SA=50\pi+140\pi\\SA=190\pi[/tex]
Therefore, although this answer isn't one of the choices, the surface area of the cylinder is 190π.
I hope this helps!

Answer:
C.) 10,240 cubic feet
Step-by-step explanation:
We have to first find the area of the base by multiplying 32 by 32. 32 * 32 is equal to 1024. Next, we multiply by the height divided by 3. 30/3 is equal to 10, so the total volume is equal to 1024 * 10, which is 10240.

512 c2 so A sorry if im wrong
Answer:
384
Step-by-step explanation:
So there are 6 faces in a cube so first you need to know how big is one face then just multiply by 6 for all 6 faces. so 8*8 = 64. that means 64 is the area of one face.
then multiply that by 6 to get the total surface area.
there it is your answer 384 the 3rd option there

What is the value of X
Answer:
11=x
Step-by-step explanation:
since the lines are parallel the distances between each section of line is proportional to each other.
5/6=(x-1)/12
multiply both sides by 12
12(5/6)=(x-1)12/12
10=(x-1)
add 1 to both sides
10+1=x-1+1
11=x

1. Find the slope and the y-intercept
of the graph of the linear equation.
y = -7x + 2
A) slope: -3; y-intercept: 2
1
B) slope: 2; y-intercept: -7
C) slope: -7; y-intercept: 2
D) slope: 2; y-intercept: -7
Answer:
c) slope: -7 ; y-intercept: 2
Step-by-step explanation:
Note the slope intercept form:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
Note in this case:
y = (-7)x + 2
y = y
m = -7
x = x
b = 2
c) slope: -7 ; y-intercept: 2 is your answer.

Apply the distributive property to factor out the greatest common factor.
Answer: 4(2x - 5)
Step-by-step explanation:
factors of 8 : (2, 2), 2
20 : (2, 2), 5
Therefore the GCF is 2*2 = 4
8x/4 = 2x and -20/4 = -5
4(2x - 5) = 8x - 20
