Cos A = (589^2 + 513^2 - 741^2) / 2 x 589 x 513 = 61,009 / 604,314 = 0.1010
A = cos^-1(0.1010) = 84.2 degrees
Let the depth of the submarine be x, then
sin 84.2 = x / c = x / 513
x = 513 sin 84.2 = 510
Therefore, the depth of the submarine is 510.
Each year, the car's value decreases by 19%. 14,650 times 0.19 is $2783.50, meaning that his car loses $2783.50 in value per year. The chart values are:
1. $11,866.50
2. $9083
3. $6299.50
4. $3516
As for B, the equation would be $14,650 - $2783.50y
When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(they have the same base of x)
(you can't combine the exponents because they have different bases of y and x)
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or
or
Add the exponents together
Make the exponent positive

Considering that the powers of 7 follow a pattern, it is found that the last two digits of are 43.
<h3>What is the powers of 7 pattern?</h3>
The last two digits of a power of 7 will always follow the following pattern: {07, 49, 43, 01}, which means that, for , we have to look at the remainder of the division by 4:
- If the remainder is of 1, the last two digits are 07.
- If the remainder is of 2, the last two digits are 49.
- If the remainder is of 3, the last two digits are 43.
- If the remainder is of 0, the last two digits are 01.
In this problem, we have that n = 1867, and the remainder of the division of 1867 by 4 is of 3, hence the last two digits of are 43.
