Answer:
Hopefully, the problem is worded as follows:
a after 3 years = A (1.08)^3 = 1.2597 A after 3 years (invested at end of year)
a after 2 years = A (1.08)^2 = 1.1664 A after 2 years
a after 1 year = A (1.08) = 1.08 A
a last year = A
adding the columns
4 a = 4.5061 A where A is the amount invested each year and a is the total worth of such an investment
or a = 1.12653 A
A = a / 1.12653 = 550,000 / 1.12653 = 488,226 for the total investment
Each year 488,226 / 4 must be invested = 122,057
B. To be careful, use brackets: 10(1*2) + 4x which will be 20 + 40x or as you have it, 10*2 + 40x.
The answer is the third graph.
I attach the graph again to avoid misunterstandings.
To find the reflection over the x - axis, just note that
f(x) becomes - f(x), so t
he graph of ∛x is - ∛x.
Graphically is pretty easy because you just have to
translate all the points of f(x) to the opposite side across the x-axis.
Answer:
8.57 miles
Step-by-step explanation:
It is provided in the question that,
<em>Janice drove 360 miles in 6 hours.</em>
<em>Formula to calculate speed = distance / time</em>
Speed at which Janice drove = 360 / 6
= 60 miles/hours
<em>To find, </em>
<em>distance Janice will cover in 7 hours </em>
Distance = speed * time
Distance = 60miles/hour * 7 hours
Distance = 8.57 miles
So the distance Janice travel i 7 hours at 60miles/hr is 8.75miles
