answer:

f (2) = 6

step-by-step explanation:

first plug in 2 as x
f(2) basically means x = 2

f (2) = 3(2)^0 - 2(2)^-1 + 4

solve the exponents and use PEMDAS

f (2) = 3(2)^0 - 2(2)^-1 + 4

f (2) = 3 - 1 + 4

2 to the 0th power is 1
3 times 1 is 3 so we get 3
2 to the power of -1 is 1/2 (it gets flipped)
-2 times 1/2 is -1 so we get 1
there is nothing to do with +4 so we bring it down
now, simply solve it using PEMDAS

f (2) = 3 - 1 + 4

f (2) = 2 + 4

f (2) = 6

natita [175]

Answer:

It is an identity, the proof is in the explanation

Step-by-step explanation:

csc(A)-cot(A)=tan(A/2)

I'm going to start with right hand side

tan(A/2)=(1-cos(a))/(sin(a)) half angle identity

tan(A/2)=1/sin(a)-cos(a)/sin(a) separate fraction

tan(A/2)=csc(a)-cot(a) reciprocal and quotient identities

6. Which expression is equivalent to -21 + 28x?

Rina8888 [55]

Solution,
-28x^2+35x
take the common,
-7x(4x-5)
The answer is -7x(4x-5)
Here,
If we solve,
-7x(4x-5)
Then, the answer would be:
= -7x*4x+7x*5
= -28x^2+35x
Hope it helps
Good luck on your assignment
