Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level
Answer:
Step-by-step explanation:
The trigonometric function that uses the value of the angle, the value of the adjacent side (e) and the hypotenuse is the cosine of the angle as shown below:
Answer: -22
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given information</u>
m = 1
n = -3 (2) = -6
<u>Given expression</u>
2m - 4n (3m - 4)
<u>Substitute values into the expression</u>
=2(1) - 4(-6) (3(1) - 4)
<u />
<u>Simplify by multiplication</u>
=2 + 24 (3 - 4)
<u />
<u>Simplify values in the parentheses</u>
=2 + 24 (-1)
<u>Simplify by multiplication</u>
=2 - 24
<u>Simplify by subtraction</u>
=
