Part A: Find a rational number that is between 7.7 and 7.9. Explain why it is rational. (2 points)

1 answer:

7 0

Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.

Part B.
sqrt(60) = 7.75
sqrt(60) cannot be written as a fraction of integers. It is a decimal number that never ends and never repeats.

Can someone help with this problem on literal equations to get variable A by itself? Will give lots of points

-BARSIC- [3]

Answer:

Step-by-step explanation:

Part A

xf = xo + vo* t + 1/2 a*t^2 Subtract xo

xf - xo = 0*t + 1/2 a*t^2 multiply by 2

2(xf - xo) = at^2 divide by t^2

2(xf - xo ) / t^2 = a

Part B

Givens

xo =0

vo = 0

a = 10 m/s^2

xf = 120 m

Solution

xf = xo + vo* t + 1/2 a*t^2 Substitute the givens

120 = 0 + 0 + 1/2 * 10 * t^2 Multiply by 2

120*2 = 10* t^2

240 = 10*t^2 Divide by 10

240/10 = t^2

24 = t^2 take the square root of both sides.

√24 = √t^2

t = √24

t = √(2 * 2 * 2 * 3)

t = 2√6
