Answer 1
Answer: The answer is A.80.3
equation to use is C=cos^-1 [a^2+B^2+-2^2 /2ab
A=21
B=33
C=36
21^2+33^2-36^2
21^2=441
33^2=1089
36^2=1296
441+1089=1530
1530-1296=234
234/2=117
cos^-1*117=80.28
rounded gives you 80.3, hope this helps :D

Can someone solve the expression: 0.14 + (107.5 / 30) * 0.04?

Answers

The answer will be 0.3

To solve this mathematical expression. Here's a step-by-step solution:

1. Firstly, we have to follow the order of operations, also known as BIDMAS/BODMAS/PEDMAS: Brackets/Orders (or Parentheses/Exponents), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

2. Look for anything in parentheses (or brackets). We have (107.5 / 30). Let's solve this division problem first. The result is 3.5833333333333335.

3. The next step would be to multiply this result by 0.04 to follow the order of operations: 3.5833333333333335 * 0.04, which equals 0.14333333333333334.

4. Lastly, add 0.14 to the result of the multiplication which we've just calculated: 0.14 + 0.14333333333333334.

5. After doing the addition, we end up with the final answer, which is 0.2833333333333333.

I hope this breakdown clarifies the process of solving this relatively complex expression! Please let me know if you have any more questions.

#SPJ11

Determine the domain of the function.f as a function of x is equal to the square root of eleven minus x.

Answer Choices:
All real numbers except 11
x > 11
All real numbers
x ≤ 11

Answers

Answer:

Option D, x ≤ 11

Step-by-step explanation:

We have to determine the domain of the function.

f(x) = √(11-x)

This function is defined for the positive values of ( 11 - x ) because under root of negative terms is not defined.

Therefore, domain of the given function will be ( 11 - x ) ≥ 0

x ≤ 11

Option D, x ≤ 11 is the answer.
