Answer:
Step-by-step explanation:
Remark
- x is opposite the 90 degree angle. It is the hypotenuse.
- 13 makes up the 57 degree angle. It is the side adjacent.
- The adjacent side and the hypotenuse define the cos(theta).
Formula
cos(theta) = adjacent side / hypotenuse
Givens
Theta = 57 degrees
Hypotenuse = x
Side adjacent = 13
Solution
- Cos(57) = 13 / x Multiply both sides by x
- x*cos(57) = 13 Divide by cos(theta)
- x = 13/cos(57)
- x = 13 / cos(57)
- cos(57) = 0.5446
- x = 13/ 0.5446
- x = 23.87
Answer:
B
Step-by-step explanation:
y= 9,800 x 2 ^x = 1,254,400
Just substitute x for 7
y= 9800 x 2 ^7 = 1,254,400
Answer:
If 18.2% of the 378 milliliters of solution is acid, 0.182(378) ml of the solution is acid. Multiplying this out, our final answer is 68.8 ml of the solution is acid.
