Answer:
y = 5, 3; x = 171, 155
Step-by-step explanation:
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155

The y intercept is 2.5 which can be written as 5/2
The slope is negative since it is going down and to the right and for every one square down it does 2 over so the slope is -1/2
That gives the equation y = -1/2 + 5/2
Find the future value of an ordinary annuity of $200 paid quarterly for 6 years, if the interest rate is 10%, compounded quarterly. (Round your answer to the nearest cent.)
Answers
Answer:
Future value is $1543.12
Step-by-step explanation:
From the question, present value = $200, rate = 10%, years = 6.
So that future value of ordinary annuity can be calculated by,
FV = [tex]\frac{A{[(1+r)^{n} - 1]}}{r}[/tex]
where: FV is the future value, A is the annuity, r is the rate, and n is the number of years.
FV = [tex]\frac{200[(1+0.1)^{6}-1] }{0.1}[/tex]
= [tex]\frac{200[1.1^{6}- 1] }{0.1}[/tex]
= [tex]\frac{200*0.771561}{0.1}[/tex]
= [tex]\frac{154.3122}{0.1}[/tex]
FV = $1543.122
The future value of the ordinary annuity is $1543.12.

Answer:
The answer is B.
Step-by-step explanation:
In order to solve this problem, you need to combine like terms, which in this case, are the x's. So, if you add the numbers with the x's together, you get 3x + 12y. The 12y remains untouched because there are no other terms with the same variable.

Let C(t) be the amount of U.S. cash per capita in circulation at time 1. The table, supplied by the Treasury Department, gives values of C(t) as of June 30 of the specificd year. Interpret and estimate the value of C'(1980).
Answers
Answer:
Following are the solution to this question:
Step-by-step explanation:
C'(t) was its time, in years, or t shift of cash per unit. That C'(1980) meaning, therefore, becomes the change of cashier's population to t = 1980.
They could either use t = 1970 or t = 1990 to approximate the C'(1980) price. When using t = 1970:
[tex]C'(1980) = \frac{[C(1980) - C(1970)]}{[1980 - 1970]}\\\\[/tex]
[tex]= \frac{(571 - 265)}{10}\\\\ = \$ \ 30.6 \\[/tex]
t = 1990:
[tex]C'(1980) = \frac{[C(1980) - C(1990)]}{[1980 - 1990]}[/tex]
[tex]= \frac{(571 - 1063)}{ -10} \\\\= \$ \ 49.2[/tex]

Given that,
To find the multiplicative inverse of 0.13.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is the inverse of a number?
The inverse of the particular number is that number when it is multiplied by the number that gives the unit. i.e. ab = 1
Here,
Let the required multiplicative inverse be x,
The product of a number and its multiplicative inverse is equal to 1
So,
0.13*x = 1
x = 1 / 0.13
Thus, the required inverse of 0.13 is 1 / 0.13.
