Answer:
domain: {2, -1, 5, -3}
range: {2, 4, 2, 0}
Step-by-step explanation:
domain : of all the input values shown on the x-axis.
range : the set of possible output values shown on the y-axis.
There are 2000 pounds in 1 ton
So, to to get how many pounds are in 12 tons, multiply 12 by 2000
12 x 2000 = 24,000
24,000 lbs
276,000 because the one at the end is the ten, the 3 is a hundred, the 4 is a thousand, and the 6 is the ten thousand
Answer:
75 degrees
Step-by-step explanation:
The shape is a trapezoid. When finding angle measurements in trapezoids:
Angle A + Angle C = 180 degrees
Angle B + Angle D = 180 degrees
Because you need to find the angle of B, we will use Angle B + Angle D = 180 degrees to solve this. Angle D is 105 degrees, so 105 + Angle B = 180. 180-105 equals 75, so angle B is 75 degrees.
Answer:
The length of the third piece of the ramp is;
D. 9.24 feet
Step-by-step explanation:
The given parameters are;
The height of the ramp = 8 feet
The angle between the piece that forms height and the base = 90°
The angle formed by the third piece connecting the height of the ramp to the furthest point and the 8 foot piece = 30°
Let 'y' represent the 8-foot piece forming the height, and let 'r' represent the third piece, by trigonometric ratio, we have;

Therefore, we get;


The length of the third piece, r ≈ 9.24 feet
