1a. Gabriella uses these services:
  Checking (she has an account)
  Debit card

1b. At A+ Bank, Gabriella's monthly charges will be
  $1 (for checking) + $2.50 (for debit card) = $3.50

At NextGen Bank, Gabriella's monthly charges will be
  0 (for checking) + $0.50*20 (for debit card) = $10.00

1c. A+ Bank is a better deal for Gabriella. The fixed fees there are lower than the variable fee at NextGen Bank because she uses her debit card so much.

Two​ fire-lookout stations are 190 miles ​apart, with station A directly south of station B. Both stations spot a fire. The bearing of the fire from station A is Upper N 55 degrees Upper E and the bearing of the fire from station B is Upper S 60 degrees E. How​ far, to the nearest tenth of a​ mile, is the fire from each lookout​ station?


Step-by-step explanation:

Let's say the position of the fire is point C.

Bearings are measured from the north-south line.  So ∠BAC = 55°, and ∠ABC = 60°.

Since angles of a triangle add up to 180°, ∠ACB = 65°.

Using law of sine:

190 / sin 65° = a / sin 60° = b / sin 55°


a = 181.6

b = 171.7

Station A is 181.6 miles from the fire and station B is 171.7 miles from the fire.

A researcher calls 1,800 randomly chosen residential telephone numbers, and then asks to speak with an adult member of the household. The researcher asks, “How many 3D movies have you watched in a movie theater in the past 12 months?”4. What source of bias is likely for the question asked?


The bis which is likely for the given question by the researcher is response bias.

Given that,

A researcher calls 1,800 randomly chosen residential telephone numbers, and then asks to speak with an adult member of the household.

The researcher asks, “How many 3D movies have you watched in a movie theater in the past 12 months?”.

Response bias happens when the people who needs to respond does this in an inaccurate way or wrongly.

Here almost no people will be correctly remembering the exact number of movies they watched in a year.

Also, they may be volatile to social desirability and may say less or more number of movies.

So there happens a response bias.

Hence the correct bias is response bias.

Help pls with answer!!!Rewrite the function in the given form.



g(x) = (-2)/(x-1)+5\n\n

The graph is shown below.



Notice that if we multiplied the denominator (x-1) by 5, then we get 5(x-1) = 5x-5.

This is close to 5x-7, except we're off by 2 units.

In other words,

5x-7 = (5x-5)-2

since -7 = -5-2

Based on that, we can then say,

g(x) = (5x-7)/(x-1)\n\ng(x) = (5x-5-2)/(x-1)\n\ng(x) = ((5x-5)-2)/(x-1)\n\ng(x) = (5(x-1)-2)/(x-1)\n\ng(x) = (5(x-1))/(x-1)+(-2)/(x-1)\n\ng(x) = 5+(-2)/(x-1)\n\ng(x) = (-2)/(x-1)+5

This answer can be reached through alternative methods of polynomial long division or synthetic division (two related yet slightly different methods).


Compare the equation g(x) = (-2)/(x-1)+5\n\n to the form g(x) = (a)/(x-h)+k\n\n

We can see that

  • a = -2
  • h = 1
  • k = 5

The vertical asymptote is x = 1, which is directly from the h = 1 value. If we tried plugging x = 1 into g(x), then we'll get a division by zero error. So this is why the vertical asymptote is located here.

The horizontal asymptote is y = 5, which is directly tied to the k = 5 value. As x gets infinitely large, then y = g(x) slowly approaches y = 5. We never actually arrive to this exact y value. Try plugging in g(x) = 5 and solving for x. You'll find that no solution for x exists.

The point (h,k) is the intersection of the horizontal and vertical asymptote. It's effectively the "center" of the hyperbola, so to speak.

The graph is shown below. Some points of interest on the hyperbola are

  • (-1,6)
  • (0,7) .... y intercept
  • (1.4, 0) .... x intercept
  • (2, 3)
  • (3, 4)

Another thing to notice is that this function is always increasing. This means as we move from left to right, the function curve goes uphill.

An image has coordinates: A (-2, 4), B (4, 6), C (3, -4). Given a scale factor of 3, what would be the new coordinates?Group of answer choices

A' (6, -12), B' (-12, 18), C' (9, -12)

A' (1/2, 1), B' (3/2, 2), C' (3, 9/2)

A' (-6, 12), B' (-12, -18), C' (9, -12)

A' (-6, 12), B' (12, 18), C' (9, -12)


A’(-6,12) B’(12,18) C’(9,-12) because all numbers must be multiplied by your scale factor in this case 3
