Each of the input changes is 1 unit.
Each of the output changes is 3 units, so the function is linear with a slope of 3.
The output is -2 when the input is 0, so the function is
.. y = 3x -2
Answer:
The ramp must cover a horizontal distance of approximately 19.081 feet.
Step-by-step explanation:
Given the vertical distance (
), measured in feet, and the angle of the wheelchair ramp (
), measured in sexagesimal degrees. The horizontal distance needed for the ramp (
), measured in feet, is estimated by the following trigonometrical expression:
(1)
If we know that
and
, then the horizontal distance covered by this ramp is:

The ramp must cover a horizontal distance of approximately 19.081 feet.
Answer: 1
Step-by-step explanation:
16 * 1/2 = 8
7x + 1 = 8
7x = 7
x = 1
Answer: 5 units
Step-by-step explanation:
The area of a parallelogram is
. SInce we know the area and the height, we can directly plug the values into this equation and solve for the base.
20=b(4) [divide both sides by 4]
b=5 units
Answer:
102 mg
Step-by-step explanation:
Let's convert 28 pounds to kgs.
Since 1 kg = 2.2 pounds, we can find:

So 28 pounds is 12.73 Kg
Since 8mg is given per kg, for 12.73 kg, the amount given should be:
12.73 * 8 = 101.84
Rounded to nearest whole number, that is, 102 mg
