Answer:
Step-by-step explanation:
I believe the correct answer from the choices listed above would be the first option. The graph that shows a function where f(2) = 4 would be the graph that passes through point (2,4) which is shown in the first graph. Hope this answers the question.
The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Step-by-step explanation:
The given is,
Roberto score on math quiz at last week is 74
This week he made an 85 on the quiz
Step:1
Formula to calculate the percentage of increase the score,
× 100...........(1)
From the given,
Final score = 85
Starting score = 74
Equation (1) becomes,
× 100
=
× 100
= 0.1486486 × 100
= 14.86486 %
≅ 14.87 %
Percentage of increase = 14.87 %

The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Answer:
$42.35
Step-by-step explanation:
The discount is 6% so in decimal form it is .06. Multiply that by the original amount $42.50.
42.5 x .06 = 2.55
That is the discount amount so you would subtract you from the original amount.
42.5 - 2.55 = 39.95
That is the cost of the textbook after the discount is applied. To apply the sales tax you would:
39.95 x .06 = 2.397
That is the tax amount so you would add it to the cost of the book.
39.95 + 2.397 = 42.347
Since we are talking about money you would round it to 2 decimal points.
$42.35
Similarly you could just do:
1.0 - .06 = .94
42.5 x .94 = 39.95
It will give you the same answer if you don't want to do it the first way.
Hope it helps! (:
