with an expression like 3x6 you can separate parts of the expression using parentheses like: 3(2+4)

you can find ways to separate a variable (like 6) into a sum of two addends

ex 1+5

0+6

3+3

so a distributive version of 3x6 is 3(2+4) = (3x2) + (3x4)

Answer:

$500

Step-by-step explanatioThe numberber of years driven is the first and second year

= 2

Miles driven

First year= 15,500

Second year= 14,500

Therefore the cost of depreciation can be calculated as follows

15,500-14,500/2

= 1000/2

= 500

Hence the cost of depreciation is $500

v = 20.8x^2 - 458.3x + 3,500 represents the value of a car from 1964 to 2002. What year did the car have the least value? (x= 0

Karo-lina-s [1.5K]

See the picture for all detail, I have done it by hand.
Few important steps;
-Take the first derivative
-Put it equal to zero
-you get the x value which is equal to 11
-Now for the check that x=11 is the least value or not, take the second derivative
-As, the 2nd derivative is positive so it is the least value

As x=0 in 1964 add 11 to it so at x=11 we get 1975 so in this year car have least value

You are making payments for a $1,475 loan that has a simple interest rate of 7.54% for 5 years.

lbvjy [14]

Answer:

$2,031.08

Step-by-step explanation:

You want to calculate the interest on $1475 at 7.54% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

I=P x r x t

P is the principal amount, $1475.00.

r is the interest rate, 7.54% per year, or in decimal form, 7.54/100=0.0754.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1475 × 0.0754 × 5 to get that:

The interest is: $556.08

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 1475.00 + 556.08 = 2031.08. For example:

If you borrowed the $1475.00, you would now owe $2031.08

If you loaned someone $1475.00, you would now be due $2031.08

If owned something, like a $1475.00 bond, it would be worth $2031.08 now.
