Answer:
For what value of the constant c is the function f continuous on (-infinity, infinity)?
f(x)
=cx2 + 8x if x < 3
=x3 ? cx if x ? 3
Step-by-step explanation:
Answer:
It's cos(x) = 1/2
Step-by-step explanation:
The First one is A and the second one is also A.
Answer:
D. joint variation
Step-by-step explanation:
y = 14x/z
y is directly proportional to x and inversely proportional to y
Constant of proportionality = 14
Direct variation is given as
y = kx
Where, k = constant of proportionality
Inverse variation is given as
y = k/z
Where, k = constant of proportionality
When they are jointly combined
y = kx/z

3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
