For this case, the first thing we must take into account is the following definition:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Substituting values we have:
 Trip 1:
 
50 = v * t1
 We cleared t1:
 t2 = (50) * (1 / v)
 Trip 2:
 
300 = (3 * v) * t2
 We cleared t2:
 t2 = (300/3) * (1 / v)
 t2 = (100) * (1 / v)
 Rewriting:
 t2 = 2 (50) * (1 / v)
 t2 = 2 * t1
 Answer:
 
His new time compared with the old time was:
 
Twice the old time.
 
t2 = 2 * t1.

Find the midpoint of the segment with the given endpoints. ​ (9​,9​) and ​(6​,8​)
mars1129 [50]

<u>Answer:</u>

The mid-point is (7.5, 8.5).

<u>Step-by-step explanation:</u>

We are given two points (9​,9​) and ​(6​,8​) as the endpoints for a line segment and we are to find the midpoint of this segment.

We know that the formula for finding the mid point is:

<em>Mid point = (\frac {x_1 + x_1 }{ 2 } ,\frac { y_1 + y_2} {2} )</em>

So substituting the given values of the coordinates of the endpoints in the above formula to get:

= (\frac {9 + 6}{2} , \frac {9 + 8}{2} )

= (\frac {15}{2} , \frac {17} {2} )

=(7.5, 8.5)

Therefore, the mid-point is (7.5, 8.5).

When f(x)=5x^2-2x+5, evaluate f(-3)
patriot [66]

Answer:

f(-3)=56

Step-by-step explanation:

When evaluating a specific input for a function, you just plug that input in for x.

So in this case, f(-3)=5(-3)^2-2(-3)+5

f(-3)=5(-3)^2-2(-3)+5

f(-3)=5(9)+6+5

f(-3)=45+6+5

f(-3)=56
