Answer:

Correct Answer: (8,2)

Step-by-step explanation:

Dilation about the origin

Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation.

In such cases, every point (x,y) dilated by a factor of k is mapped to the point (kx,ky).

The point R=(4,1) is dilated by a scale factor of 2 (k=2), thus the coordinates of its image are (2*4,2*1) = (8,2)

Which set of ordered pairs could be generated by an exponential function?

olasank [31]

Answer:

The correct option is (1,2), (0, 1), (1, 2), (2, 4).

Step-by-step explanation:

Consider the provided ordered pairs.

The exponential function is in the form of $f(x)=ab^x$

Where, a is the initial amount $a\neq 0$ and b is the rate of change b>0, $b\neq 1$

The graph of each exponential function passes through the point (0, a),

$f(0)=a\cdot b^0 = a$ and $a\neq 0$

Therefore, Option 1 and 2 and 4 are false.

Hence, the correct option is (1,2), (0, 1), (1, 2), (2, 4).

Evaluate the function rule for the given value . Y=12 times 3x for x=-2

algol13

$y=12*3^{x}$

plugging x=-2 in the given equation we get

$y=12*3^{-2}$

=12/3²

=12/9

=4/3

so answer is 4/3

Ryan is studying. The number of minutes he has studied varies directly with the number of calories he has burned. See the

Pie

Answer:

0.1 minute per calorie burned. Slope is up 0.1 , right 1. or 0.1/1

Step-by-step explanation:

You find a point such as (10,100) or (20,200) then you divide the number of minutes by calorie burned to get minutes per calorie burned.
