Answer:
Non-linear: red graph, table 3, table 1
Linear: blue graph, green graph, table 2
Step-by-step explanation:
The blue and green lines are straight lines, so they are linear. The red line is curved, so that is nonlinear.
I plotted out the data from each table on a graph. Tables 1 and 3 both curve when the points are connected, and table 2’s points form a straight line when connected. I am sure there is a mathematical formula to use on these tables, so the drawing wouldn’t have been required. But I knew this would at least get the answers.
Hope it helped.
Answer:
7
Step-by-step explanation:
we need to first find the area
4.5 x 4 = 18
1.5 x 2 = 3
18 - 3 = 15
15/2.25 = 20/3
20/3 is 6.666666666666666666666666666666.....
6+1 = 7

Sorry but I have NO clue :(
Answer:
150 vouchers to wash trucks were sold
250 vouchers to wash compact cars were sold
Step-by-step explanation:
Here, we are interested in calculating the number of each type of vouchers sold.
Let the number of vouchers to wash trucks be x while the number of vouchers to wash compact trucks be y.
Firstly, we know that both sums up to be 400.
Mathematically;
x + y = 400 •••••••••(i)
Secondly,
since a voucher to wash trucks sell $4, and we sold a total of x, the amount generated from selling is 4 * x = $4x
Same way for the vouchers to wash compact cars, we have a total of $3 * y = $3y
The sum of both gives $1350, which is the total sales.
Mathematically;
4x + 3y = 1350 ••••••(ii)
So we have two equations to solve simultaneously;
x + y = 400
4x + 3y = 1350
Multiply equation i by 4 , we have;
4x + 4y = 1600
4x + 3y = 1350
Subtract equation ii from i, we have 4y-3y = 1600-1350
y = 250
From equation 1, we know that
x + y = 400
This means that;
x = 400 -y
x = 400 -250
x = 150
Jodi can draw a monthlyincome of approximately $2,154 from her investment.
Option B is the correct answer.
It is the interest we earned on the interest.
The formula for the amount earned with compoundinterest after n years is given as:
A = P
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
The first step to solve this problem is to find the futurevalue (FV) of the initial investment of $328,133.32 over 25 years, compounded monthly at 6.2% interest rate.
We know that the futurevalue (FV) can be calculated using the formula:
Where:
PV = Present value (initial investment) = $328,133.32
r = Interest rate per year = 6.2%
n = Number of years = 25
Substituting the values, we get:
FV ≈ $889,076.76
The futurevalue (FV) of the investment after 25 years is approximately $889,076.76.
Next, we need to calculate the monthlyincome that Jodi can draw from this investment.
To do this, we can use the formula for the present value (PV) of an annuity:
Where:
C = Monthly income
r = Interest rate per year = 6.2%
n = Number of years = 25
We need to solve for C, which is the monthly income that Jodi can draw from the investment.
Substituting the values, we get:
Simplifying this equation, we get:
C ≈ $2,153.96
Therefore,
Jodi can draw a monthlyincome of approximately $2,153.96 from her investment.
Rounding to the nearest dollar, the answer is B. $2,154.
