Answer:

$7-2i$

Step-by-step explanation:

As you're used to do in the real plane, midpoint is the average of Real and Imaginary part. So $\frac{5+9}2 +i \frac{-7+3}2 = \frac{14}2+i\frac{-4}2 = 7-2i$

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d is 0.15 per second of time, t.

garik1379 [7]

Here the function given by

f(d)=0.15t

Now

f(1):-

$\\ \sf\longmapsto f(1)=0.15(1)=0.15m$

$\\ \sf\longmapsto f(2)=0.15(2)=0.3m$

Sandra normally takes 2 hours to drive from her house to her grandparents' house driving her usual speed. However, on one partic

Rudiy27

Answer:

Her usual driving speed is 38 miles per hour.

Step-by-step explanation:

We know that:

$s = \frac{d}{t}$

In which s is the speed, in miles per hour, d is the distance, in miles, and t is the time, in hours.

We have that:

At speed s, she takes two hours to drive. So

$s = \frac{d}{2}$

$d = 2s$

However, on one particular trip, after 40% of the drive, she had to reduce her speed by 30 miles per hour, driving at this slower speed for the rest of the trip. This particular trip took her 228 minutes.

228 minutes is 3.8 hours. So

$0.4s + 0.6(s - 30) = \frac{d}{3.8}$

$3.8(0.4s + 0.6s - 18) = d$

$3.8s - 68.4 = 2s$

$1.8s = 68.4$

$s = 38$

Her usual driving speed is 38 miles per hour.
