Answers

Answer 1
Answer: B) 32

Explanation:

let H = number of expensive high price stereo

systems

let L = number of less expensive low price

stereo systems

H +L = 50 =

3,000H + 80OL = 110,000

H = 50 - L (now replace)

3,000 (50 - L) + 800 L = 110,00

150,000 - 3,000L + 800L = 110,000

150,000 - 110,000 = 3,000L - 800L =

40,000 = 2,2OOL

L = 40,000 / 2,200 = 18.18 = 18 lower priced = =

stereo systems H = 50 - 18 = 32 higher priced stereo systems

=

=

(3,000 x 32) + (800 x 18) = 96,000 + 14,400 = 110,400

Even though the answer is not exact, if you had 33 high cost stereo systems, your inventory's cost = $112,600 which is $1,600 off

For what values of a does the equation ax^2+x+4=0 have only one real solution?

Answers

Answer:

1/16

Step-by-step explanation:

To have one real solution, the discriminant must be 0.

b² − 4ac = 0

1² − 4a(4) = 0

1 − 16a = 0

a = 1/16

Abigail invested $29,000 in an account paying an interest rate of 2.1% compoundedcontinuously. Assuming no deposits or withdrawals are made, how much money, to
the nearest dollar, would be in the account after 8 years?

Answers

Final answer:

Abigail can find out how much money she will have after 8 years continuously compounding interest by using the formula A = P*e^(rt), where A is the final amount, P is the principal ($29,000), r is the interest rate (0.021), and t is time in years (8). Once the values are inserted into the formula, it can be solved to find the total amount.

Explanation:

The problem that Abigail is facing can be solved using the continuous compound interest formula which is A = P*e^(rt). Here, A stands for the amount of money in the account after t years, P is the principal amount (the initial amount of money), r represents the annual interest rate (expressed as a decimal), and t is time in years. In this context:

  • P = $29,000
  • r = 2.1 /100 = 0.021
  • t = 8 years

Plug in these values into the formula:

A = 29000 * e^(0.021 * 8)

When calculated this would give the total amount to the nearest dollar.
