Given:
side lengths of right triangles = 12 cm ; 16 cm ; 20 cm
lateral area = 192 cm²
lateral area of a triangular prism = perimeter * height
192 cm² = (12 cm + 16 cm + 20 cm) * height
192 cm² = 48 cm * height
192 cm² / 48 cm = height
4 cm = height
The height of the pedestal in the shape of a triangular prism is 4 cm.
So, y-intercept is (0,3) and x-intercept is (3/7,0)
Step-by-step explanation:
We are given:

We need to find y-intercept and x-intercept
Finding y-intercept
To find y-intercept we put x =0
Solving:

So, y-intercept is (0,3)
Finding x-intercept
To find x-intercept we put y =0
Solving:

So, x-intercept is (3/7,0)
So, y-intercept is (0,3) and x-intercept is (3/7,0)

Does it tell you what (x) stands for
Answer:
{ x | x ≥ 0 }
Step-by-step explanation:
Given,
There is a straight line started from (0, 9) and passes through (8, 1),
∵ In the coordinate plan, the values of x are arranged in increasing order to the right side of the y-axis,
Thus, the line is defined for all real values of x greater than 0,
Hence, Domain of the line = All real numbers greater than equal to 0,
i.e. { x | x ≥ 0 }
Thus, FIRST OPTION is correct.
