Dwayne purchased a computer from Techtronic's, Inc. for $2,600 in 2007. The rate of
depreciation is 7%. Which would be the best estimate for the value of the computer in
2010?
Answer:
[tex]\$2091.3[/tex]
Step-by-step explanation:
Let P denotes initial value of the product, r% is the annual depreciation rate and t denotes time period.
Depreciation (d) = [tex]P(1-\frac{r}{100})^t[/tex]
Put [tex]P=\$2,600,\,r\%=7\%,\,t=3[/tex] years
Therefore,
[tex]d=P(1-\frac{r}{100})^t\\\\=2600(1-\frac{7}{100})^3 \\\\=2600(\frac{93}{100})^3\\\\=\$2091.3[/tex]

Charles invested $15,000 in stocks and bonds. He made a 12% profit on his stock investments and a 5% profit on his bond investments. If Charles's combined profits on both types of investments were $1,450, how much did he invest in stocks?
Answer:When you leave the interest in your
account or reinvest the money you earn on your
investments, the money you earn starts to earn
money too. Over time, the magic of
compounding works, allowing your money to
grow with dramatic results. The more time you
have to save, the less money you need to save
because of compounding. And the longer you
wait to start saving, the more you have to spend
to reach your goal. For example, let’s assume
that Maria’s savings grow by 5% a year. If she
starts to save $243 a month now, it will cost her
$58,320 to have $100,000 in twenty years. If
she waits 10 years to start saving, she will have to
save $644 a month for 10 years, and it will cost
her $77,280 to reach $100,000 in twenty years.
Step-by-step explanation:Hope this helps!!!!
Answer:
$10,000 invested into stocks

Two investments totaling $37,500 produce an annual income of $2210. One investment yields 6% per year, while the other yields 5% per year. How much is invested at each rate?
Answer:
a = $33,500 at 6%
b = $4,000 at 5%
Detailed Answer:
37,500 = a + b
b = 37,500 - a
a = 37,500 - b
2,210 = a*6% + b*5%
2,210 = a*6% + 5%*(37,500 - a)
2,210 = a*6% - a*5% + 37,500*5%
2,210 = a*(6% - 5%) + 1,875
335 = a*( 6/100 - 5/100)
335 = a*( 1/100)
a = (335*100)/1
a = $33,500
b = 37500 - a
b = 37500 - 33500
b = 4000
Plug back in to check if the amounts invested at each rate equal $2210:
$2210 = a*6% + b*5%
$2210 = 33500*6% + 4000*5%
$2210 = $2010 + $200
$2210 = $2210

why couldn't klog hear music through his phone
The reason why Klog could not hear music through his phone was that it was chordless.
What is a Pun?This refers to the use of words to show their double meaning and how one meaning can sound the same and mean a different thing.
Hence, we can see that from the knowledge of chords, we can see that music is written in chords and Klog's phone did not have a cord and this was the meaning of the pun to show that Klog could not listen to music because his phone did not have a cord.

Solve the equation using the method of factorisation-
x2 - 4x - 45 = 0
x² + 4x -9= (x + a)^2 + b
Find the value of a and the value of b.
Answer:
X = 9,X= -5, a = 2, b = -13
Step-by-step explanation:
For (1),
Using Cross-factorization,
it can be reduced to (X - 9)(X + 5) = 0
Equate each factor to 0:
we have X = 9 and X = -5
For (2),
It is the case of completing the Square,
add 4 so we get the completed square ( we want the form X^2 + 2a + a^2)
(X^2 + 4X + 4) - 9
can be simplified to (X+2)^2 -9
However since we added 4 it means we have to subtract 4
So it becomes (X+2)^2 -9 -4
= (X+2)^2 -13

The local park has a circular pond with a radius of 9 feet. What is the pond's circumference?
Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
