Answer:
The volume for the triangular prism is 40.5 cubic inches.
Step-by-step explanation:
Given:
The base of a triangular prism has an area of 18 square inches .
And the height is 4.5 inches.
Now, to get the triangular prism volume.
The base area = 18 square inches.
Height = 4.5 inches.
Now, to get the volume of prism we put formula:
Therefore, the volume for the triangular prism is 40.5 cubic inches.
Answer
Find out the perimeter of the isosceles triangle.
To prove
As shown in the figure.
P(0,4) , Q(-2,0) and R(2,0) are the vertices of the triangle PQR.
Formula
As P(0,4) and Q(-2,0)
In the isoceles triangle the two sides of the triangles are equal .
Therefore PQ = PR
As Q(-2,0) and R(2,0)
QR = 16 unit
Answer:
m = - 1/4
Step-by-step explanation:
When two line is perpendicular to each other the product of them is - 1
So let the other line be B
Gradient of B = t
Gradient of A = 4
therefore m = - 1/4
