The interest rate r required to increase your investment p to the amount a in t years is found by . Find the interest rate r for

Dahasolnce [82]

Answer:

The interest rate was of 0.1173 = 11.73%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$A = E + P$

In this problem, we have that:

$A = 10000, P = 8100, t = 2$

So

$A = E + P$

$10000 = E + 8100$

$E = 1900$

So

$1900 = 8100*I*2$

$I = \frac{1900}{8100*2}$

$I = 0.1173$

The interest rate was of 0.1173 = 11.73%.

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the m

Alecsey [184]

Answer:

The answer to this question can be defined as follows:

i) $\bold{p(x)= -5x^2+ 217x- 1,401} \\$

ii) x=22 units

iii) Maximum profit: 953.45

Step-by-step explanation:

Given value:

p(x) = 211 − 5x \\

C(x) = 1,401 + 16x

The formula for calculating the profit function value:

$\to \bold{P(x)= xp(x) - C(x)}$

$= x(211-5x)- 1,401 + 16x\\\\= 211x -5x^2-1,401+16x\\\\= -5x^2+ 217x- 1,401 \\$

The formula for calculating the value for maximum profit:

$p'(x) = - 10x + 217 =0$

$217= 10x\\\\x= \frac{217}{10}\\\\x= 21.7$

So, the production level is 22 units

Maximum profit:

$\to p(21.7)= - 5 (21.7)^2+217 (21.7) -1,401\\\\$

$=-5 (470.89) +217 (21.7) -1,401\\\\=-2354.45+ 4708.9-1,401\\\\= 953.45$

The difference between a number and 17 is 96. Find the number

jeka57 [31]

Answer:

The number is 79

Step-by-step explanation:

Let the number be 'x'

x + 17 = 96

Subtract 17 from both sides,

x + 17 -17 = 96 - 17

<h3> x = 79</h3>
