Answer:
Function:
c = f(w) = 0.49, 0 < w ≤ 1
= 0.70, 1 < w ≤ 2
= 0.91, 2 < w ≤ 3
Step-by-step explanation:
Yes, the relation described can be interpreted as a function.
Here, c is the cost of a mail letter. c depends upon w, which is the weights of the mail letter.
As described in the question, the relation can be expressed as a function.
c can be expressed as a function of w in the following manner:
c(cost of mail) = f(w), where w is the independent variable and c is the dependent variable
c = f(w) = 0.49, 0 < w ≤ 1
= 0.70, 1 < w ≤ 2
= 0.91, 2 < w ≤ 3
where, c is in dollars and w is in ounces.
Answer:
Step-by-step explanation:
We are going to apply algebra to solve for the exponential growth
we know that the expression for the exponential formula is
where
a = the amount before measuring growth or decay
= 10,000
r = growth or decay rate = 23%= 0.23
x = number of time intervals that have passed
since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)
hence the formula becomes
The expression that will give the population value is
P= principal (initial deposit) ($7000)
i= interest (5%)
t= # of years (3)
Total amount = P (1 + i)^t
T= $7000(1 + 5%)^3
T= 7000(1.05)^3
multiply exponents before regular multiplication
T= 7000(1.157625)
Total= $8,103.38 after 3 years
Hope this helps! :)
Answer:
slope: undefined
Step-by-step explanation:
vertical line slope = (y-y') / (x-x')
x-x' = 0
slope: undefined
Move k to the other side to isolate d.
So we will get 3d = 8c - 8d - k
Now divide both sides by 3 to isolate d.
So d = 8/3c - 8/3d - k/3
