Answer:
m = 3/20
Step-by-step explanation:
3/5 = 4m
3/(5*4) = m
3/20 = m
Check
3/5 = 4*3/20
3/5 = 12/20
Answer:
fgh(x)=4
-14
Step-by-step explanation:
when solving composite fuctions we go from the right to the left
meaning we replace the x in the g function with the entire h function
then replace the x in the f function with the entire new g function
h(x)=
g(
)=
-5
f(
-5)=4(
-5)+6
f(
-5)=4
-20+6
fgh(x)=4
-14
//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root
Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3

Answer:
38 mpg
Step-by-step explanation:
Initial efficiency = 39 mpg
Initial speed = 40 mph
Final speed = 50 mph
The efficiency drop between 40 mph and 50 mph is given by:

The total efficiency drop from 40 to 50 mph is:

Therefore, the efficiency at 50 mph is:
