Divide and simplify to the form a+bi. 5+6i 5+6i 6+ i (Simplify your answer. Type an integer or a fraction. Type your answer in the form a+bi.)

Answers

Answer:

$-(6)/(37) + (371)/(37)i$

Step-by-step explanation:

We need to evaluate $((5+6i)(5+6i))/(6+i)$

(5+6i)(5+6i) = (25 + 36i² + 60i) = (25 - 36 + 60i) = -11 + 60i

= $(-11+60i)/(6+i)$

Now we rationalize the denominator.

Now, multiplying both the numerator and denominator by (6-i)

$(-66 + 11i + 360i - 60i^2)/(36 - i^2) = (-66 + 60 + 371i)/(37) = (-6 + 371i)/(37)$

= $-(6)/(37) + (371)/(37)i$

Formula used:

(a+b)² = a² + b² + 2ab

A lion runs at a speed of 50 mph and a cheetah runs 78 mph. If they both run at a steady rate, how far will a cheetah run in the time it takes a lion to run 13.75 miles?

Answers

Answer:

21.45 miles

Step-by-step explanation:

Key:

t=time

d=distance

We need to find the time the lion ran first.

The time the lion ran:

13.75=50•t

13.75=50t

-50t=-13.75

t=-13.75•-1/50

t = 0.275

So the lion ran in 13.75 miles in 0.275 of an hour.

Now, we need to figure out the cheetah.

0.275•78=21.45 miles

I hope this helps :-)
