A man drove x miles per hour for 3e hours and (2x-60) miles per hour for the next 4.75 hours. Express the total distance he trav
avanturin [10]

Answer:

A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.

Total distance covered by the man in terms of 'x' = (12.5x-285)miles

Step-by-step explanation:

Given:

Speed of  a man = 'x' miles/hour

Time taken = 3 hour

So, distance = product of speed and time.

Distance covered in term of 'x' =(d_1=3x)

Now,

Speed = (2x-60) miles/hour

Time taken= 4.75 hours

Distance (d_2)  = (2x-60)\times 4.75

                      = (2x\times 4.75) -(60\times 4.75)

                      = (9.5x - 285) miles

Total distance covered by the man = Summation of  d_1 and d_2

                                                           = (9.5x-285+3x)

                                                           = (12.5x-285) miles

So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.

Which graph could represent the function f(x) = (x + 3.8)2 – 2.7? On a coordinate plane, a parabola opens up. It starts in quadr
Vikki [24]

Answer:

The last choice is correct.

Step-by-step explanation:

The given function is

f(x) =  {(x + 3.8)}^{2}  - 2.7

This is a parabola with a=1>0.

The graph will therefore open up.

By comparing to

f(x) = a(x - h)^{2}  + k

The vertex is at (h,k)= (-3.8,-2.7)

Therefore the graph crosses the x-axis and the y-axis.

Also the vertex is in the 3rd quadrant because both x and y are negative in this quadrant.

Answer:

On a coordinate plane, a parabola opens up. It starts in quadrant 2, crosses the x axis where the vertex is in quadrant 3, and crosses the x-axis back into quadrant 2.
