V0 = 5750 is the initial investment
v2 = 6080 is the value after 2 years

Plug those values into the given formula and then use a calculator
r = sqrt(v2/v0) - 1
r = sqrt(6080/5750) - 1
r = sqrt(1.05739130434782) - 1
r = 1.02829533906743 - 1
r = 0.02829533906743
r = 0.028
r = 2.8%

Final Answer: Choice C) About 2.8%

ollegr [7]

Answer:

x = 0 , x = 9

Step-by-step explanation:

to find the zeros let f(x) = 0 , that is

x(x - 9) = 0

equate each factor to zero and solve for x

x = 0

x - 9 = 0 ⇒ x = 9

Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. How many cups, x,
siniylev [52]

Answer:

18 cups.

Step-by-step explanation:

We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: 20\leq 1.50x-6.50.

To find number of cups x to make a profit of at least  $20 we will use our given inequality.

20\leq 1.50x-6.50

20+6.50\leq 1.50x

26.50\leq 1.50x

x\geq \frac{26.50}{1.50}

x\geq \frac{53}{3}

x\geq 17.6666666

Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
