Answer:
15 yd³
Step-by-step explanation:
Formula for the volume of a square pyramid is V = 1/3 Bh
So...
V = 1/3 (3*3)(5)
V = 1/3 (9)(5)
V = 1/3 (45)
V = 15
You need to solve :
8*x=10 for x
Answer:
The discriminant is 0
There is 1 real solution
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
In the equation y = x² - 4x + 4, a is 1, b is -4, and c is 4.
Plug in these values into the formula:
D = b² - 4ac
D = (-4)² - 4(1)(4)
D = 16 - 4(4)
D = 16 - 16
D = 0
So, the discriminant is 0.
With a discriminant of zero, there is one real solution.
So, the number of real solutions is 1.
