Answer: 3.6 cups or 3 3/5 cups

Step-by-step explanation: what i would do here is set up a proportion. Change 3/4c to .75 cups as it’s easier to place in a proportion (and less confusing).. cross multiply .... (.75 x 48= 36) then divide 36 by 10 and that will give you x

Without graphing, determine whether the function y = ( 5 . 2 )^x represents exponential growth or exponential decay.

Papessa [141]

exponential growth is your answer. If it is not a negative then it wont be exponential decay. if it is a positive then it is growth

A rectangle has vertices E(-4, 8), F(2, 8), G(2, -2) and H(-4, -2). The rectangle is dilated with the origin as the center of di

Marizza181 [45]

Answer:

The dilation on any point of the rectangle is $P'(x,y) = \frac{5}{2}\cdot P(x,y)$ .

Step-by-step explanation:

From Linear Algebra, we define the dilation of a point by means of the following definition:

$G'(x,y) = O(x,y) +k\cdot [G(x,y)-O(x,y)]$ (1)

Where:

$G(x,y)$ - Coordinates of the point G, dimensionless.

$O(x,y)$ - Center of dilation, dimensionless.

$k$ - Scale factor, dimensionless.

$G'(x,y)$ - Coordinates of the point G', dimensionless.

If we know that $O(x,y) = (0,0)$ , $G(x,y) =(2,-2)$ and $G'(x,y) =(5,-5)$ , then scale factor is:

$(5,-5) = (0,0) +k\cdot [(2,-2)-(0,0)]$

$(5,-5) = (2\cdot k, -2\cdot k)$

$k = \frac{5}{2}$

The dilation on any point of the rectangle is:

$P'(x,y) = (0,0) + \frac{5}{2}\cdot [P(x,y)-(0,0)]$

$P'(x,y) = \frac{5}{2}\cdot P(x,y)$ (2)

The dilation on any point of the rectangle is $P'(x,y) = \frac{5}{2}\cdot P(x,y)$ .

The data in the table represent the fuel economy (mpg) for a car at different speeds (mph).

sweet-ann [11.9K]

My graphing calculator computes the best match to a cubic function, which predicts mileage of about 39.7 mpg at 65 mph.

The second-best match is to a quadratic function, which predicts mileage of 29.8 mpg at 65 mph.

Linear regression predicts mileage of about 36.6 mpg at 65 mph.

It appears the best choice of those offered is (D) about 36 mpg.

What is the equation of the line in slope-intercept form?

kondor19780726 [428]

Answer:

The answer would be C because b=+16 which means that it intercepts line y at 16, which is shown in the graph.
