Answer:
16x^2 + 9x^2 + 9x + 13.
Step-by-step explanation:
6x^3 + 8x^2 – 2x + 4 +10x^3 + x^2 + 11x + 9
Bringing like terms together:
= 6x^3 + 10x^3 + 8x^2 + x^2 - 2x + 11x + 4 + 9
= 16x^2 + 9x^2 + 9x + 13. (answer).
Answer: The common difference is 8
Step-by-step explanation:
First Use the formula for the second to generate the first two numbers.
= 2^3n-2
Put in 1 for the first term and you will get 2 and the second term is 16 and to get from 2 to 16 you will multiply by 8.
The inverse functions of sine, cos and tan functions are csc, sec and cot respectively.
<u>Step-by-step explanation:</u>
The reciprocals of sine, cos and tan functions are csc, sec and cot functions. The reciprocal of cosine function is secant, (sec) sec θ =
The inverse or reciprocal function is cosecant (csc), 
The inverse tangent function is cotangent (cot) , expressed in two ways:
or 
So
then its reciprocal or inverse is termed as cot θ.
