Find f(-2) for f(x)=2*3^x

Find the difference between (2,3) and (4,1)

Pavel [41]

Answer:

The distance in question is √8, or 2√2.

Step-by-step explanation:

Distance, not difference.

As we move from (2, 3) to (4, 1), x (the horizontal distance between the two points), increases by 2 and y (the vertical distance) decreases by 2.

Hence we have a triangle with horizontal leg length 2 and vertical leg length 2. According to the Pythagorean Theorem,

(distance)^2 = 2^2 + 2^2, or (distance)^2 = 4 + 4 = 8.

The distance in question is √8, or 2√2.

1/2 9/10 4/5 which on e go first to put in lowest number on the left

Verizon [17]

Since 1/2 = .5, 4/5 = .8, and 9/10 = .9. I found these out by dividing the numerator by the denominator. Now that we have them in decimal form, we can order them from least to greatest: 1/2, 4/5, and 9/10. You can also figure out how to order them from least to greatest by finding a common denominator, like 10. 1/2 = 5/10, 4/5 = 8/10, and 9/10 stays the same. (Looking back to the first example, if you don’t have a calculator you can do it this way to find the decimal forms) then you can order them from least to greatest!

Hope one of these meathods helped you, and happy holidays!

Then, isolate x:

-x=-5

Then, divide by -1:

12. The volume V of a gas varies inversely with the pressure P. When the volume is 75 inches cubed, the pressure is 30 pounds pe

charle [14.2K]

Answer:

Let V = the gas' volume and P = its pressure. The volume of a gas in a container varies inversely with the pressure on the gas:

V = k/P

where k is a constant. To find the value of k, plug in the one known point, V = 390 cubic inches when P = 7 pounds per square inch and solve for k:

V = k/p

390 = k/7

390*7 = k

2730 = k

The full equation, then, is:

V = 2730/P

To find the volume when P = 9 pounds per square inch:

V = 2730/9 = _____ cubic inches

Step-by-step explanation:

Let V = the gas' volume and P = its pressure. The volume of a gas in a container varies inversely with the pressure on the gas:

V = 2730/9 = _____ cubic inches
