Answer:

If 12 eggs cost $2.04, then figure out how much 1 egg costs. You do that by dividing the total by the amount = 0.17. Take that number and multiply by how many eggs and you'll get the total which is $3.06

Find the value of the points (5,1) , (-2,-3) and (8,2m) are collinear

svp [43]

Answer:

m = 19/14 so the third point is (8, 19/7).

Step-by-step explanation:

If they are co-linear then the the slope will be equal.

The slopes of the lines are:

(difference in y coordinates) / (difference in corresponding x coordinates)

Slope between the first 2 points = (-3-1) / (-2-5) -4 / -7

= 4/7.

So if the 3 points are co-linear:

4/7 = (2m - -3) / (8 - -2)

4/7 = (2m + 3 / 10

7(2m + 3) = 40

14m + 21 = 40

14m = 19.

m = 19/14.

The back of Tom's property is a creek. Tom would like to enclose a rectangular area, using the creek as one side and fencing for

ICE Princess25 [194]

Answer:

76,050 ft²

Step-by-step explanation:

If the area must be rectangular, let L be the length of the side opposite to the creek, and S be the length of the remaining two sides.

The perimeter of the fencing and the area of the pasture are:

$780 = L+2S\\A= LS\\\\L=780-2S\\A=-2S^2+780S$

The value of S for which the derivate of the area function is zero is the length of S that maximizes the area of pasture:

$\frac{dA}{dS}=0=-4S+780\\S= 195\\L=780-(2*195)=390$

The maximum possible area is:

$A_{MAX}=390*195=76,050\ ft^2$
