The answer is option 2,
2x10^10
I think it is -2, if that helps
Answer:
Choice A. 3.
Step-by-step explanation:
The triangle in question is a right triangle.
- The length of the hypotenuse (the side opposite to the right angle) is given.
- The measure of one of the acute angle is also given.
As a result, the length of both legs can be found directly using the sine function and the cosine function.
Let 
denotes the length of the side opposite to the 
acute angle, and 
be the length of the side next to this acute angle.
.
Similarly,
.
The longer leg in this case is the one adjacent to the acute angle. The answer will be 
.
There's a shortcut to the answer. Notice that 
. The cosine of an acute angle is directly related to the adjacent leg. In other words, the leg adjacent to the angle will be the longer leg. There will be no need to find the length of the opposite leg.
Does this relationship 
holds for all acute angles? (That is, 
?) It turns out that:
Answer:
35/4
Step-by-step explanation:
Change -1 2/3 into -5/3. Change -5 1/4 into -21/4.
Multiply -5/3 by -21/4= 105/12
Reduces down to 35/4
Answer:
The check digit is 7.
Step-by-step explanation:
Check digit can be calculated by the following way:
- Add all the digits except the check digit that is the last digit on the right side.
Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3
Total = 47
- Add the digits at odd starting from left, double this amount and finally add it with the total from step 1.
= 0 + 4 + 7 + 3 + 1 + 3
Sum = 18
Doubling the sum = 36
Adding it with the total from step 1, we get
Total = 36 + 47
Total = 83
- Subtract the last digit of the total from step 2 with 10, and this will be check digit.
Check Digit = 10 - 3
Check Digit = 7
