Answer:
a=10
Step-by-step explanation:
The question can be interpreted as
F∝a
If we introduce proportionality constant k, we have
F= k.a
28= k. 7
k= 28/7
k= 4
Then the equation can be written as
F= 4.a
To find, a when F = 40?
F= 4.a
40=4 × a
a= 40/4
a= 10
Answer:
Step-by-step explanation:
The second set. It contains (2,2) and (2,7), so it fails the vertical-line test.
You need to put the equations for f(x) and g(x) into the other equation.
(4x+1 - x² -5)(x)
Simplify the parentheses
(-x²+4x-4)(x)
Now multiply the two together
-x³+4x²-4x
Since that isn't any of the choices, I assume you just need it simplify the (f-g) part of the equation.
-x²+4x-4 or A would be the answer
