Jack took out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what

Kruka [31]

Answer: $32,732.58

Step-by-step explanation:

To calculate the total loan payment over the course of the loan period, use the future value formula:

= Loan amount * (1 + rate) ^ number of years

As this loan is compounded monthly, you need to convert certain terms to monthly figures:

Number of periods = 6 * 12 months = 72 months

Interest = 4.5 / 12 = 0.375%

Total payment:

= 25,000 * ( 1 + 0.375%)⁷²

= $32,732.58

(-3x)²-(3x-2)²-6*(2x-1.5)

Ilya [14]

Without the instructions, I can only assume that you are to "expand the given expression."

Following order of operations rules requires that (3x-2)^2 and -6(2x-1.5) be evaluated first.

(3x-2)^2 = 9x^2 - 12x + 4 and -6(2x-1.5) = -12x + 9

Then we have 9x^2 - (9x^2 - 12x + 4) -12x + 9

the 9x^2 terms cancel, leaving us with 12x - 4 - 12x + 9 = 5 (answer)

What is the simplest form of x^2+5X-36/x^2-16<br> X+9/X+4<br> 9/4<br> X+9/X-4<br> -9/4

Digiron [165]

Answer:

$\frac{ {x} + 9}{x - 4}$

Step-by-step explanation:

$\frac{ {x}^{2} + 5x - 36}{ {x}^{2} - 16} \\ \\ = \frac{ {x}^{2} + 9x - 4x- 36}{ {x}^{2} - {(4)}^{2} } \\ \\ = \frac{ x({x} + 9) - 4(x + 9)}{ (x + 4)(x - 4) } \\ \\ = \frac{ ({x} + 9) \cancel{(x - 4)}}{ \cancel{(x + 4)}(x - 4) } \\ \\ = \frac{ {x} + 9}{x - 4}$

The data for Shawn's phone has 32000 megabytes if storage for photos . She wants to increase the amount by 4% if each photo uses

Law Incorporation [45]

Answer:

Yes, she will have have enough new memory for 200 additional photos.

Step-by-step explanation:

Given:

Initial memory for storage, $M_{o}=32000\textrm{ megabytes}$

Increase in memory $=4%$

Therefore, increase in memory, $\Delta M=\frac{4}{100}\times 32000=1280\textrm{ megabytes}$

Now, memory consumed by 1 photo = 5 megabytes

So, memory consumed by 200 additional photos = $200\times 5=1000\textrm{ megabytes}$

Memory left in her phone = 1280 - 1000 = 280 megabytes

Therefore, she will have additional 280 megabytes of memory left in her phone.

As memory consumed by 200 additional photos is less than that of the increase in memory, therefore, she does have enough new memory for 200 additional photos.

X-7y=12 and 3x+12y=36

olchik [2.2K]

Are you asked to factor or what? I would write the 1st x-7y-12=0 and 3x+12y-36=0. and the 2nd one can be factored out. for example factor out a 3.
