Answer:
Explanation:
We were given the function:
Discontinuity occurs when the denominator equals zero
When x = -4, the value of the denominator is zero
Removable discontinuity occurs when both the numerator and denominator are zero
We will check this by inputting x = -4 in the expression, we have:
Thus, when x = -4, we have a removable discontinuity
Hence, our answer is: (x, y) = (-4, 0)
Answer:
C
Step-by-step explanation:
the answer is C
12*8=96
15*8=120
17*8=136
The equation is y = -2x + 120
Since the numbers are going down there is a negative slope.
Substitute 40 in and you will get 40 as your answer.
Heat is transferred as thermal energy by the interaction of moving particles
This is actually a lot easier than it seems :-)! There is a formula in trig called the Pythagorean Theorem. This is cos^2 x + sin^2 x = 1. This means that cos^2 x means the exact same thing as 1-sin^2 x. If we plug this in, we get 1-2sin^2 pi/9. Another helpful trigonometric equation is the double angle identity. This is cos(2x)=1-2sin^2 (x). Plugging our equation from earlier in, we get cos 2pi/9.
