The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to

nadya68 [22]

Answer:

D(12) = 2,600 miles

It means a distance of 2,600 miles is already traveled from home after 12 hours

Step-by-step explanation:

To find D(12); all we have to do is to substitute the value of 12 for D

We have this as;

D(12) = 3260-55(12)

D(12) = 2,600

In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours

That's "15 choose 5"

$\displaystyle{15 \choose 5} = \dfrac{15! }{5! 10!} = \dfrac{15 \cdot 14 \cdot 13 \cdot 12 \cdot 11}{5 \cdot 4 \cdot 3 \cdot 2 \cdot 1} = (15/(5(3))(14/2)(13)(12/4)(11)\\\\= 7(13)(3)(11)=231(13)=3003$

Answer: 3003 ways

B(7, 2) and C(-1,-9) are the endpoints of a line segment. What is the midpoint M of that line

Oksana_A [137]

Answer:

(3,-3.5)

Step-by-step explanation:

$Mid-point formula : \frac{ x_{1} +x_{2}} {2}, \frac{y_{1}+y_{2} }{2} \\\\x=\frac{7+(-1)}{2} , y= \frac{2+(-9)}{2} \\x= \frac{6}{2} , y= \frac{-7}{2} \\x=3 , y= -3.5$

Midpoint M of the line segment is (3,-3.5)

The ratio of coordinates in the image to the coordinates of the original will tell you the dilation factor when diation is about the origin (as here).

Jx'/Jx = -2/-3 = 2/3

This same ratio is true for the other 5 coordinate values, so we know that ...

... the scale factor used in the dilation is 2/3.

_____

Jy'/Jy = -8/-12 = 2/3

Kx'/Kx = -4/-6 = 2/3

Ky'/Ky = -10/-15 = 2/3

Lx'/Lx = -6/-9 = 2/3

Ly'/Ly = -8/-12 = 2/3
