The time, t, required to drive to a certain distance varies inversely with the speed, r. if it takes 12 hours to drive the dista

kap26 [50]

T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R

At 85 mph we have

T = 720 / 85 = 8.47 hours (answer)

What value of B makes the expression. x² + Bx + 81 a perfect square trinomial?

Oxana [17]

Answer:

B.) 18

Step-by-step explanation:

To find the correct b value we use this formula

b² - 4ac = 0

b = What we are solving for

a = 1

c = 81

b² - 4(1)(81) = 0

b² - 324 = 0

b² = 324

$b = \sqrt{324}$

b = ±18

And 18 is one of the answer choices

So B.) 18 is the correct answer.

I'm not sure if they want "w = abc"

I used that equation to solve part 2

What pattern do you see in the powers of 4?

Over [174]

All of them are even numbers. You will not find a power of 4 that is an odd number. Also, all of the numbers have a 4 or a 6 or both. For example,
4^3= 64

4^8= <span>65536

I hope this helps:)</span>
