Step-by-step explanation:
cos(90) = 0
around this point the cos function "mirrors" with opposite signs. cos(<90) is positive and cos(>90) is negative.
but |cos(90-a)| = |cos(90+a)| for 0 <= a <= 90
75 = 90 - 15
105 = 90 + 15
so, a = 15
and because of
|cos(90-a)| = |cos(90+a)| for 0 <= a <= 90
cos (90-15) = cos(75) = -cos(90+15) = -cos(105)
Answer:
Distribute the 3 to 4y and 8
Step-by-step explanation:
Answer:
y=5x-8
Step-by-step explanation:
Slope=m=(7-3)/(3-2)
y=5x+b=>2=5*2+c=>c=-8
So y=5x-8
f.g and its domain is 24x²-36x-24; all real numbers.
Given, f(x) = 3x - 6; g(x) = 8x +4.
We need to find the value of f.g
<h3>What is a domain?</h3>
The domain of a function; In mathematics, the domain of a function is the set of inputs accepted by the function.
Now, (f.g)(x)=(3x-6)(8x+4)
=24x²-48x+12x-24
=24x²-36x-24
Therefore, f.g and its domain is 24x²-36x-24; all real numbers.

Answer:
43 1/3
Step-by-step explanation: Not sure what that second part it but for that equation it is 43 1/3 because you need to isolate the variable by adding the 18 1/3 to the 25 and whatever that equals is your answer so I added
g-18 1/3=25
18 1/3+25
g= 43 1/3
^ see it says g= ___ and that is what g equals
