Answer:
The parent function f(x) is equal to
The translations is 3 units to the left and 5 units down
Step-by-step explanation:
we have
The vertex of the function h(x) is the point (-3,-5)
we know that the parent function f(x) is equal to
The vertex of the function f(x) is the point (0,0)
so
The rule of the transformation of f(x) to h(x) is equal to
(x,y) -----> (x-3,y-5)
That means ----> The translations is 3 units to the left and 5 units down
Answer:
the total number of shingles is 3060
Step-by-step explanation:
Please have a look at the attached photo.
We need to find the total are of the roof.
The are of the trapezoid is:
= 1/2 (20+30)*15
= 375
The are of the triangle:
= 1/2(1.5*10)
= 7.5
=> We need to find the total are of the roof is:
The are of the 2 trapezoids + The are of the 2 triangles
= 375 *2 + 7.5
*2
= 765
Given in the question that, the shingles are 1 foot by 1 foot, but they overlap by 0.75 square foot so the usable area of the shingle is only 0.25
So the total number of shingles is:
765 / 0.25
= 3060
