Answer:
X > (whatever the symbol is) 0
Step-by-step explanation:
kinda like algebra:
x + 2 > 2
X > 0
One example is they help them develop projects
Answer:
f(-2) = 9
Step-by-step explanation:
Given that,
f(x) = x² + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2)² + (-2) + 7
= 4-2+7
= 9
Hence, the value of f(-2) is equal to 9.
Answer:

see the explanation
Step-by-step explanation:
we know that
The area of the base of a cylinder is given by the formula

where
r is the radius of the circular base
If the radius is doubled
then

The new base area is


so

therefore
The new area of the base is 4 times the area of the original base
Parametrically for real t the line is



That's three equations; we substitute into





The intersection is a single point (7,-6,5).
