Which formula can you use to find the radius (r)r if you know that C=2πr?

1 answer:

3 0

First of all, it is 2r $\pi$ and it would be divide by 3.14 (pi) and then you should have the diameter. Then divide by 2 to find radius.

My car gets 23 miles per gallon at 60 miles per hour. Is the number of miles I can drive at 60 miles per hour a linear function

stiv31 [10]

9514 1404 393

Answer:

yes

Step-by-step explanation:

The constant ratio (23 mi)/(1 gal) tells you the number of miles is a linear function of the number of gallons.

miles = (miles/gallon) × gallons

miles = constant × gallons . . . . . a linear function of gallons

It took Brian 6 hours to drive to the sales conference. He took the same route on the way back home, but

g100num [7]

Answer: 54 mph

Step-by-step explanation:

d-the distance

s+9 - the speed to the conference

d=6*(s+9)

s- is the speed on the way back home

d=7*s

so 6*(s+9)=7*s

6s+54=7s

-6s -6s

54= 7s-6s

s=54 mph

Tyler concludes that 5x² will always have a larger output for the same value of x.

<u>Look at the graph below and the table given</u>

Take a random value: x = 0

When 5x², y = 0

When 2^x, y = 1

Here, 1 > 0, making 2^x > 5x²

Hence, 2^x is greater than 5x² at this point. making Tyler's point not applicable.

Disagree with Tyler's point.
