4. For the three-step question that follows, provide your answer to each question in the given workspace. Identify each step with a coordinating response. Be sure to clearly label each part of yo response as Part A, Part B, and Part C.
Part A: Ava was asked to find the value of the expression 13t - 8r2 when t = -10 and r =
2. Her work is shown below, but she made a mistake. What was Ava's mistake?
13t - 8r2
13( - 10) - 80 - 2)
131 – 10) - 804)
130 - 8(4)
-138 - (4)
-552
Part B: Evaluate the expression correctly.
Part C: Show all of your work to support your answer to Part B.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
