Answer:
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.
The nth term of an arithmetic sequence is given by:
In which is the first term and d is the common difference.
In this question:
. So
Find the value of a_5
So
These two angles are corresponding angles,
so they are congruent.
12x - 4 = 10x + 10
2x = 14
x=7
All you need to do is divide 1470 by 35, which is 42.
<span>Solve for x over the real numbers:
40^x = 15
Hint: | Eliminate the exponential from the left hand side.
Take the logarithm base 40 of both sides:
Answer: x = log(15)/log(40)</span>
Sine, Cosine and Tangent. And Sine, Cosine and Tangent are the three main functions in trigonometry. They are often shortened to sin, cos and tan. The calculation is simply one side of a right angled triangle divided by another side ... we just have to know which sides, and that is where "sohcahtoa" helps. :)
