Answer:
1. 42.95
2. 8.8 meters; -14 meters
3. -53; 780
Step-by-step explanation:
1. subtract 1985 from 2013, you get 28
plug in 28 to the equation and you get 42.95
2. plug in the values of t
-4.9 (2^2) + 1.7 (2) + 25 = 8.8
-4.9 (3^2) + 1.7 (3) + 25 = -14
3. plug in your values again
5^3 - 6 (5^2) - 8 (5) + 12 = -53
12^3 - 6 (12^2) - 8 (12) + 12 = 780
Answer:
2-x^2+x^3
Step-by-step explanation:
The expression 2-x^2+x^3 can't be simplified further since the terms in the expression are unlike terms.

Answer:
If the length of each side of a triangle is doubled then its perimeter is also doubled.
The question is an illustration of right-angled triangles
The approximated value of x is 33.5 degrees
The given parameters are:



To determine the measure of angle x, we simply make use of the following sine ratio.

So, we have:


Take arc sine of both sides

This gives

Hence, the approximated value of x is 33.5 degrees
