Answer: Choice A) There must be a vertical asymptote at x = c

Explanation:

The first limit \displaystyle \lim_{x\to c^{-}}h(x) = -\infty says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.

The limit \displaystyle \lim_{x\to c^{+}}h(x) = \infty means that as x approaches c from the right side, the y values head off to positive infinity.

Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.

If someone could help me, it’d be great!

ABC has
A as the first letter
B as the second letter
C as the third letter
The order is important

Similarly with EFG we hae
E as the first letter
F as the second letter
G as the third letter
The order is also important

Based on the orderings, we can say
A corresponds to E
B corresponds to F
C corresponds to G

Which means
A rotates to E
B rotates to F
C rotates to G

The final answer is choice C) Angle C
since we're looking for the angle that rotates or maps to angle G

Which of the following expressions represent the distance between -6 and 7 on the number​ line?
JulijaS [17]

Answer:

C

Step-by-step explanation:

The lines mean the distance away from 0. When i say lines, I mean the two "l" that accompany the numbers. I forgot what there called (good job me).

Since we want to know how far apart they are, we need to add them.

If n erasers have a weight of 80 grams, what is the total weight of 50 erasers?
Black_prince [1.1K]

Answer:

The\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.

Step-by-step explanation:

As given

if n erasers have a weight of 80 grams .

I.e

n erasera =  80 grams.

1 erasers weight .

1\ erasers\ weight = \frac{80}{n}

Now find out the weight of the 50 erasers.

Weight\ of\ 50\ erasers = \frac{50\times 80}{n}\ grams

Simplify the above

Weight\ of\ 50\ erasers = \frac{4000}{n}\ grams

Therefore\ the\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.
