Help with the length of the third side?
Answer:
C. c = 10
Step-by-step explanation:
You have to use the Pythagorean theorem:
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10
Answer:
c = 10
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + 8^2 = c^2
36+64= c^2
100 = c^2
Take the square root of each side
sqrt(100) = sqrt(c^2)
10 -c

A car traveling at 22.4 m/s skids to a stop in 2.55 s. Determine the skidding distance of
the car (assume uniform acceleration).
Answer:
57.12 m
Step-by-step explanation:
velocity= distance/time
distance= velocity×time
=22.4×2.55
=57.12 m
Answer:
d = 28.6 m
Step-by-step explanation:
Given:
vi = 22.4 m/s
vf = 0 m/s
t = 2.55 s
Find:
d = ??
d = (vi + vf)/2 *t
d = (22.4 m/s + 0 m/s)/2 *2.55 s
d = (11.2 m/s)*2.55 s
d = 28.6 m
Reasoning The midpoint of AB is on the
y-axis, and AB is parallel to the x-axis. Point A
is located in Quadrant III. Which quadrant
contains point B? Explain.
Answer:
B is in 4th quadrant.
Step-by-step explanation:
If mid point of AB is on x-axis then and A is in 3rd quadrant then B must be on the opposite side of A.Therefore it is in 4th
B is in fourth quadrant when AB is the midpoint on y axis
What is a quadrant with an example?An area enclosed by the x and y axes is known as a quadrant, and a graph has four of them.To clarify, the x and y axes divide the two-dimensional Cartesian plane into four quadrants.Quadrant I is in the upper right corner, while Quadrants II through IV are arranged from counterclockwise to clockwise.The x-axis (the horizontal number line) and the y-axis connect to divide the coordinate plane into four equal pieces in the cartesian system (the vertical number line).Due to the fact that each of these four areas takes up one-fourth of the entire coordinate plane, they are referred to as quadrants.If the center of AB is on the x-axis
A is in the third quadrant,
let two points ( -2, -2 ) in third quadrant .
then B must be on the side of A that is opposite from A.
B thus comes in fourth.
then points ( 2,-2 ) are in fourth quadrant .

DF is the altitude to the hypotenuse EC. What is the length of DE?
Select the best answer from the choices provided.
A. 3
B. 6
C.12
D. 24
Answer:
D
Step-by-step explanation:
Using the Altitude- on- hypotenuse theorem
DF² = CD × DE , substitute values
12² = 6 DE
144 = 6 DE ( divide both sides by 6 )
24 = DE → D
If using the method of completing the square to solve the quadratic equation x^2+8x+37=0, which number would have to be added to "complete the square"?
Answer:
The numbers are --> x = -4 + √21 i and x = -4 — √21 i
See the attachment for my step-by-step explanation
(solution is in red box)
The number that would have to be added in the given quadratic equation to complete the square is '-21' and this can be determined by using the factorization method.
Given :
Quadratic equation -- [tex]x^2+8x+37 = 0[/tex]
The following steps can be used in order to determine the number that would have to be added to complete the square:
Step 1 - The factorization method can be used in order to determine the number that would have to be added to complete the square.
Step 2 - Write the given quadratic equation.
[tex]x^2+8x+37 = 0[/tex]
Step 3 - Now, if '-21' is added in the above quadratic equation then the above equation becomes the complete square.
[tex]x^2+8x+37+(-21) = 0[/tex]
[tex]x^2+8x+16 = 0[/tex]

O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 85
x = 17
The angle measures are 34 degrees and 56 degrees.
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 85
x = 17
The angle measures are 34 degrees and 46 degrees.
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 95
x = 19
The angle measures are 52 degrees and 38 degrees.
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 95
x = 19
The angle measures are 19 degrees and 71 degrees.
Answer:
Equation: [tex]3x-5+2x=90[/tex]
Angle measures: 52 degrees and 38 degrees
Step-by-step explanation:
Hi there!
We're given that the two angles form a right angle, which means they add up to 90 degrees.
Knowing this, we can construct the following equation:
[tex]3x-5+2x=90[/tex]
Now, we must solve for x:
[tex]5x-5=90\\5x=95\\x=19[/tex]
Therefore, x=19. Plug this into the expression for each angle to find their measures:
[tex]3x-5\\= 3(19)-5\\= 57-5\\=52[/tex]
[tex]2x\\=2(19)\\=38[/tex]
Therefore, the two angles measure 52 degrees and 38 degrees.

What is the percentage change from 305 to 395
Answer:
29.51%
Step-by-step explanation:
The change from 305 to 395 is the difference between the two numbers. So, it would be 395 - 305 or 90. Now, to find the percentage of change, we need to find what part of the original amount is the change. In other words, we would have to divide 90 by 305. By putting this in a calculator you get about 0.2951. To convert this decimal into a percent, we would multiply by 100 giving us 29.51%.

HELP FAST A vertical slice through a three-dimensional solid produces a two-dimensional shape. (shape is a triangle)
Answer:
the surface of "C" would be a triangle if sliced vertically
Step-by-step explanation:
If vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism, option C is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
If a vertical slice through a three-dimensional solid produces a two-dimensional shape which is a triangle, it means that the solid has a triangular cross-section.
In other words, the cross-section of the solid that is perpendicular to its base is in the shape of a triangle.
A triangular prism is a solid shape that has a triangular cross-section. If you were to take a vertical slice through the prism, the resulting two-dimensional shape would be a triangle.
Hence, if vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism
