Answer:

\sqrt{137}

Step-by-step explanation:

Student A is at point (7, -5). Student B is at point (-4, -1).

We can find the distance between the two points using the distance formula.

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

d = \sqrt{(-4 - 7)^2 + (-1 - (-5))^2}

d = \sqrt{(-11)^2 + (4)^2}

d = \sqrt{121 + 16}

d = \sqrt{137}

Answer: \sqrt{137}

What is S7 for 6 – 24 + 96 – 384 + ... ?
Dmitry [639]
6 - 34 + 96 - 384 +... 
a 1 = 6 , a 2 = a 1 * ( - 4 ) ,  a 3 = a 2 * ( - 4 ), a 4 = a 3 * ( - 4)...
a 5 = - 384 * ( - 4 ) = 1,536
a 6 = 1536 * ( - 4 ) = - 6,144
a 7 = - 6,144 * ( - 4 ) = 24,576 
This is a sum of a geometric sequence:
S 7 = 6 - 24 + 96 - 384 + 1,536 - 6,144 + 24,576 = 19,662
Another way to solve this:
S 7 = a 1 * ( r^n - 1) / ( r - 1 ) = 6 * (( - 4) ^7 - 1 )/ (- 4 - 1)=
= 6 * (-16,385) / (-5 ) = 19,662

the function y = 3.75 + 1.5(x - 1) can be used to determine the cost in dollars of x miles. What is the rate of change of the co
LenKa [72]

We are given

y=3.75+1.5(x-1)

where

y is the cost in dollars

x is distance in dollars

now, we can find derivative

y'=\frac{d}{dx}\left(3.75+1.5\left(x-1\right)\right)

=\frac{d}{dx}\left(3.75\right)+\frac{d}{dx}\left(1.5\left(x-1\right)\right)

=0+1.5

so,

y'=0+1.5

So,

the rate of change of the cost in dollars with respect to the number of miles is 1.5.........Answer
