<h3>
Answer: x = 65.4</h3>
==================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(x) = 5/12
x = arccos(5/12)
x = 65.375681647836 which is approximate
x = 65.4 after rounding to one decimal place
Make sure your calculator is in degree mode. The arccosine function is the same as the inverse cosine function (shortened to 
).

Answer:
nx^(n-1).
Step-by-step explanation:
d/dx (x^n)
We multiply by n than subtract 1 from the exponent (n):
= n x^(n-1)
Numerical examples:
d(x^3) dx = 3 * x^(3-1)
= 3x^2.
d(2x^5)/dx = 5*2 x^(5-1)
= 10x^4.
Answer:
$3
Step-by-step explanation:
Given that:
Park charge for one round = $19
Reduced fee for every additional round
Number of rounds played by Tom = 6
Amount paid = $34
Amount left after 1 round :
Amount paid - first round charge
$34 - $19 = $15
Number of rounds left = (6 - 1) = 5
Charge per additional round :
$15 / 5 = $3
