<h3>Answer: C) none of the equations are identities</h3>
If you plugged theta = 0 into the first equation, then you would have
sin(45) + cos(45) = sin(0) + cos(0)
sqrt(2) = 1
which is a false equation. We don't have an identity here.
The same story happens with the second equation. Plug in theta = 0 and it becomes
cos(60) - sin(60) = cos^2(0) + tan(0)
1/2 - sqrt(3)/2 = 1 + 0
-0.37 = 1
which is false.
Answer:
19.4285714286 Step-by-step explanation: 272 divided by 14 can be calculated as follows. 272/14 math problems division
Step 1: begin by writing the formula for slope intercept form
step2: substitute the given slope for X
step3: use the order pair you given (x,y) and substitute these values for the variables x and y in the equation
step4: solve for y ( y-intercept of the graph)
step5: rewrite the original equation in step 1 substituting the slope for x and the y-intercept for y
A^2+b^2=(a+b) (a-b)
Let a^2=x^2 then a^2= x^2
Let b^2=63 them b^2= 64
b=8
Answer: (x+8) (x-8)
