Answer:

3.2 years.

Step-by-step explanation:

We are asked to find the number of years it will take an amount of $6,000 to be $8,000 compounded continuously at an annual rate of 9%.

We will use continuous compound interest formula to solve our given problem.

A=Pe^{rt}, where,

A = Amount after t years,

P = Principal amount,

e = Mathematical constant,

r = Interest rate in decimal form,

t = Time in years.

\$8,000=\$6,000e^{0.09*t}

\frac{\$8,000}{\$6,000}=\frac{\$6,000e^{0.09*t}}{\$6,000}

\frac{4}{3}=e^{0.09*t}

Switch the sides:

e^{0.09*t}=\frac{4}{3}

Now, we will take natural log of both sides.

\text{ln}(e^{0.09*t})=\text{ln}(\frac{4}{3})

0.09*t=\text{ln}(\frac{4}{3})

0.09*t=0.2876820724517808

\frac{0.09*t}{0.09}=\frac{0.2876820724517808}{0.9}

t=3.19646747\approx 3.2

Therefore, it take approximately 3.2 years for the amount of $6,000 to be $8,000.

Y=99.99+23.75(x-1) as a Y=ax+b equation
Hatshy [7]

Answer:

y = 23.75x  + 76.24

Step-by-step explanation:

We want to rewrite

y = 99.99 + 23.75(x - 1)

in the form

y = ax + b

We expand to get:

y = 99.99 + 23.75x - 23.75

Regroup similar terms:

y = 23.75x - 23.75 + 99.99

Simplify:

y = 23.75x  + 76.24

This is now of the form

y = ax + b

where a=23.75 and b=76.24

A mixture of concrete is made up of sand and cement in the ratio of 5:3.How many cubic centimeters of sand is needed to make 160
bazaltina [42]

Answer: 100\ cm^3

Step-by-step explanation:

Given

The ratio of mixture of sand and cement is 5:3

If the total volume of mixture is 160\ cm^3

Suppose there is 5x and 3x cubic centimeter of sand and cement respectively i.e.

\Rightarrow 5x+3x=160\\\Rightarrow 8x=160\\\Rightarrow x=20\ cm^3

Sand 5x=5\times 20=100\ cm^3

So, there is 100\ cm^3 of sand in the mixture

Rationalize the denominator and simplify. 5/4-√3
Yakvenalex [24]
I assume the denominator is (4-√3)
Multiple both top and bottom by (4+√3)
[5(4+√3)]/[(4-√3)(4+√3)]
=[20+5√3]/[4²-(√3)²]
=[20+5√3]/13
