Answer:
1 ft
Step-by-step explanation:
From the diagram;
Therefore
Also, AB=8+2=10ft, AD=8ft, AE=4ft. We substitute to get:
Simplify to get:
But AC=AE+EC
This implies that,
5=4+EC
EC=5-1
EC= 1 ft

Answer:
Step-by-step explanation:
We have to find a cubic function of x whose zeros are at x = √7, x = -√7 and at x = -4.
Therefore, the factors of the function will be (x - √7), (x + √7), and (x + 4)
Hence, the equation will be y = (x - √7) (x + √7) (x + 4)
