This is an exponential growth. (typing it into a graphing tool helps)
The rate of change is the slope of your function except with exponential growth/decay you are finding the rate of change over a given interval because its not a constant slope.
Answer and explanation:
V originally equals u + at, but when you plug in u, a, and t you get a number answer.
u = 2
a = 15
t = 1/5
Rewrite the expression with the numbers plugged in.
V = (2) + (15)(1/5) <em>Multiply 15 by 1/5</em>
V = 2 + 3 <em>Add 2 and 3 together</em>
V = 5
<h2><u>So V would equal 5</u></h2>
I haven't done that in a while, but i think its C
Answer:
$52.44
Step-by-step explanation:
Long method:
1. Convert the percentage into a decimal (15/100 = 0.15)
2. Multiply the decimal by the cost of the haircut (0.15 x $45.60 = $6.84)
3. Add this product by the cost of the haircut ($6.84 + $45.60 = $52.44)
Quicker Way (easier w/ a calculator)
1. Add 100% to the percentage she wants to add (100% + 15% = 115%) You can also express this as a number (115/100 = 1.15)
2. Multiply this new percentage by the cost of the haircut (1.15 x $45.60 = 52.44)
In a single equation, it would be
