Ainsley works for the owners of a bookstore. Her starting salary was 24,500, and she gets a 3% raise each year. Write an equation in function notation to represent subsidy’s salary as a function of the number of years she has been working at the bookstore. What will Ainselys salary be when she begins her fourth year working at bookstore?
Answer:
if x is the number of years she is working that the equation would be: 24,500+x*((3/100)*24,500)
Step-by-step explanation:
For her 4th year x would be 4, so for the equation above x=4:
24500+4*((3/100)*24500)=27440
What does AB equal in this problem? It’s timed
Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)

Answer:
29.4
Step-by-step explanation:
mC = 180 - 46 - 105 = 29
By Law of Sines: c/sin C = a/sin A
19.8/sin 29° = a / sin 46°
19.8/0.484 = a/0.72
a = 29.45 ≈ 29.4
Teresa is investing $20,000 in an account with 4.3% interest rate that is compounded monthly. How much money will she have if she takes her money out after 8 years?
Answer:
Teresa will have $28,200 if she takes her money out after 8 years.
Step-by-step explanation:
To be able to find the answer, you have to use the formula to calculate the future value:
FV=PV(1+i/n)^(n*t)
FV=future value
PV=present value= $20,000
i=interest rate= 0.043
n=number of compounding periods per time unit= 12
t=time in years= 8
Now, you can replace the values on the formula:
FV=20,000*(1+(0.043/12)^(12*8)
FV=20,000*1.41
FV=28,200
According to this, the answer is that Teresa will have $28,200 if she takes her money out after 8 years.
describe how a root ca be written using rational expressions, give an example
Answer:
Given an expression with a rational exponent, write the expression as a radical. Determine the power by looking at the numerator of the exponent. Determine the root by looking at the denominator of the exponent. Using the base as the radicand, raise the radicand to the power and use the root as the index
Step-by-step explanation:
example
A business has a savings account that earns a 3% annual interest rate. At the end of 1996, the business had $4,000 in the account. The formula
F = p (1+r/100)
t is used to determine the amount in the savings account.
F is the final amount,
p is the initial investment amount,
r is the annual interest rate, and
t is the time in years.
To the nearest dollar, how much did the business initially invest in 1991?
A. $3,450
B. $3,455
C. $4,631
D. $4,637
Answer:
The amount the business initially invested in 1991 is approximately;
A. $3,450
Step-by-step explanation:
The question relates to investment and finance
The parameters given are;
The annual interest rate on the business savings account = 3%
The amount the business had in the account at the end of 1996 = $4,000
The given formula used to determine the final amount in the savings account, [tex]F = p \cdot \left(1 + \dfrac{r}{100} \right )^t[/tex]
Where;
F = The final amount
p = The initial (principal) investment
r = The annual interest rate
t = The time in years
Therefore, we have;
The required information = The initial amount, 'p', the business invested in 1991
The time in years, 't', from 1991 to 1996 = 1996 - 1991 = 5
∴ The time in years from 1991 to 1996, t = 5 years
The final amount in 1996, F = $4,000
r = 3%
Plugging in the values in the given equation gives;
[tex]4000 = p\cdot \left(1 + \dfrac{3}{100} \right )^5[/tex]
Therefore;
[tex]p = \dfrac{4000}{\left(1 + \dfrac{3}{100} \right )^5} = 3,450.43513754[/tex]
To the nearest dollar, the initial amount the business invested in 1991, p ≈ $3,450.
Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent
Answer:
Please specify what the three expressions are.
Step-by-step explanation:
From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:
[tex]2(x-3)=2x-6[/tex]
Then, by evaluating it, you would get:
[tex]2x-6=2x-6[/tex] by distribution over subtraction.
[tex]2x-6+6=2x-6+6[/tex] by the additive property of equality
[tex]2x=2x[/tex] Simplify.
[tex]x=x[/tex] by the reflexive axiom.
Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.
Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.
Sorry I could not be of more help, but you did not specify what the expressions were.

Step-by-step explanation:
In 1920, a woman had 4 daughters. In 1950, each daughter had 3 daughters. In 1980, each of their daughters had 3 daughters. Finally, in 2010, each of their daughters had 3 daughters.
How many daughters were born in 2010? Explain how you determined your answer.
Answer:
108
I determined my answer by multiplying 4 x 3 x 3 x 3 = 108
Step-by-step explanation:
daughters born in 1950 = 4 x 3 = 12
daughters born in 1980 = 12 x 3 = 36
daughters born in 2010 = 36 x 3 = 108
work out giving your answer as a mixed number 4 1/6 + 2 3/4
The answer in the mixed fraction form is 6¹¹/₁₂
What is a mixed fraction?A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, and 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.
Given here, 4¹/₆+ 2³/₄ = 25/6 + 11/4
= 50+33 / 12
= 83/12
= 6¹¹/₁₂
Hence the answer in mixed fraction is 6¹¹/₁₂

6,000 is the total people who voted
10% is the percent of 18 to 29 years old
and 100% represents the circle graph because all circle graphs equal 100%
First, we use the cross multiply method, for instance, 6,000×10=60,000
Next, divide 60,000÷100 which is 600.
Therefore there are 600, 18 to 29 year olds who voted in the election.
