Answer:

Step-by-step explanation:

80 divided by 2 equals 40 and if you multiply it by 8 its 320 so the constant number is 40. So y=40x mean y=40^x

Find me equation of the circle with Center at ( 3, - 2) and radius of 3

blondinia [14]

The equation of a circle with center $(x_0,y_0)$ and radius $r$ is

$(x-x_0)^2+(y-y_0)^2=r^2$

In your case,

$x_0=3,\quad y_0=-2,\quad r=3$

Plug these values into the generic formula and you'll get your equation.

HURRY!!!!!!!!!<br><br> Given P(5,10,8) and Q(7,11,10), find the midpoint of the segment PQ.

rusak2 [61]

Answer:

$P_{m}=(6,10.5,9)$

Step-by-step explanation:

The mid point can be found with the formula

$P_{m}=(\frac{x_{1}+x_{2} }{2},\frac{y_{1} +y_{2} }{2} ,\frac{z_{1}+z_{2} }{2} )$

The given coordinates are $P(5,10,8)$ and $Q(7,11,10)$ .

Replacing coordinates in the formula, we have

$P_{m}=(\frac{5+7}{2},\frac{10+11 }{2} ,\frac{8+10}{2} )=(\frac{12}{2},\frac{21 }{2} ,\frac{18}{2} )\\P_{m}=(6,10.5,9)$

Therefore, the mid point of the segment PQ is $P_{m}=(6,10.5,9)$

Pls answer if u know :) <br><br> This is a very important homework and i was gone for days so idk

Answer:

Option B

Step-by-step explanation:

Slope of the line is calculated by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\$

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\$

so the slope(m) equals -9/5
