Dont even know where to start

Answer:

$\displaystyle M = ( 3,1 )$

Step-by-step explanation:

we are given the endpoint i.e P and Q of a line segment

we want to figure out the Midpoint of the Line segment

in order to do so we can use Midpoint formula given by

$\displaystyle M = \bigg( \frac{ x_{1} + x_{2} }{2} , \frac{ y_{1} + y_{2}}{2} \bigg)$

so let

$x_1=-2\\x_2=8\\y_1=-2\\y_2=4$

substitute

$\displaystyle M = \bigg( \frac{ - 2 + 8}{2} , \frac{ - 2 + 4}{2} \bigg)$

simplify addition:

$\displaystyle M = \bigg( \frac{ 6}{2} , \frac{ 2}{2} \bigg)$

simplify division:

$\displaystyle M = ( 3,1 )$

hence,

the Midpoint of the line segment is (3,1)

bacteria colonies can increase by 73% every 2 days. if you start with 150 bacteria microorganisms, how large would the colony be

slavikrds [6]

Using an exponential function, it is found that the colony will have 1344 bacteria after 8 days.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

$A(t) = A(0)(1 + r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

Considering the initial amount of 150, and the growth rate of 73% each 2 days, the equation is given by:

$A(t) = 150(1.73)^{\frac{t}{2}}$

Hence, after 8 days, the amount of bacteria is given by:

$A(8) = 150(1.73)^{\frac{8}{2}} = 1344$

Direct Variation - Item 2845

Brums [2.3K]

The equation of direct proportion is y = 62x

<h3>Direct variation</h3>

Two quantities are said to vary directly proportional to each other when an increase in one leads to an increase in the other or a decrease in one leads to a decrease in the other.

Direct variation is given by:

y = kx

where y, x are the variables and k is the constant of proportionality.

The equation of direct proportion is y = 62x
