suppose 7,500 is invested at 1.5%, compounded continuously. what will the account balance be in 16 years?

viktelen [127]

Answer:

$\boxed {\boxed {\sf \$9,534.37}}$

Step-by-step explanation:

The formula for continuously compounded is:

$A=Pe^{rt}$

where P is the principal amount, r is the interest rate as a decimal, and t is the amount of time.

The principal amount is $7,500 and time is 16 years. The interest rate is 1.5%. Convert this to a decimal- divide by 100 or move the decimal places two spots to the left.

1.5/100= 0.015 or 1.5 --> 0.15 --> 0.015

Now we know all the values and can substitute them into the formula.

$P= 7500 \\r= 0.015 \\t= 16$

$A= 7500(e^{0.015*16})$

Solve the multiplication in the exponent first.

$A= 7500(e^{24})$

Solve the exponent.

$A= 7500 (1.27124915)$

$A=9534.368627$

Round to the nearest cent (hundredth place). The 8 in the thousandth place tells us to the round the 6 to a 7.

$A=9534.37$

The account balance will be <u>$9,534.37</u> after 16 years.

What are the zeros of the quadratic function f(x) = 2x2 + 8x – 3? x = –2 – StartRoot StartFraction 11 Over 2 EndFraction EndRoot

Phantasy [73]

Answer:

The zeros are

$x=-2+\frac{\sqrt{22}}{2}$

$x=-2-\frac{\sqrt{22}}{2}$

Step-by-step explanation:

we have

$f(x)=2x^{2}+8x-3$

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

Equate the function to zero

$2x^{2} +8x-3=0$

so

$a=2\\b=8\\c=-3$

substitute in the formula

$x=\frac{-8\pm\sqrt{8^{2}-4(2)(-3)}} {2(2)}$

$x=\frac{-8\pm\sqrt{88}} {4}$

$x=\frac{-8\pm2\sqrt{22}} {4}$

$x=-2\pm\frac{\sqrt{22}}{2}$

therefore

$x=-2+\frac{\sqrt{22}}{2}$

$x=-2-\frac{\sqrt{22}}{2}$

What is the answer for this problem cause i am very confused

EleoNora [17]

41.8, angle y and the measurement angle labeled as just "138.2" are supplementary angles, meaning that when you add them together they equal 180. So all you have to do is subtract 138.2 from 180 and you get your answer which is 41.8.

jasmine needs 300 centimeters of fabric to make her new dress. The fabric costs $5 for each meter. How much will her fabric cost

Fed [463]

The cost of 300 cm fabric is $15.

Step-by-step explanation:

Given,

Cost of fabric is $5 per meter.

To find the cost of 300 cm fabric.

1 m = 100 cm

We will apply unitary method.

Cost of 100 cm of fabric is $5

Cost of 1 cm of fabric is $ $\frac{5}{100}$

Cost of 300 cm of fabric is $ $\frac{5}{100} X300$

= $ 15

Hence,

The cost of 300 cm fabric is $15.
