Answer:

D) y < 1/3x - 1

Step-by-step explanation:

the equation of the line is y= 1/3x-1, then the dark part represents all the values that less than the values of y. The broken line means 'strongly', then the sign should be '<'.

During the school year, each student planted 2 x 10^2 trees as part of a community service project. If there are 3.5 x 10^3 stud

amm1812

Answer:

Total number of trees planted = $7\times 10^{5}$ trees

Step-by-step explanation:

Trees planted by each student = $2\times 10^2$

Total number of students = $3.5\times 10^3$

Using unitary method to find total number of trees planted by all the students in school.

1 student plants = $2\times 10^2$ trees

$3.5\times 10^3$ student would plant = $(2\times 10^2)\times (3.5\times 10^3)$

We apply the product rule of exponents to multiply $[a^xa^y=a^{x+y}]$

⇒ $(2\times 3.5)\times(10^2\times 10^3)$

⇒ $7\times 10^{2+3}$

⇒ $7\times 10^{5}$ trees

Total number of trees planted = $7\times 10^{5}$ trees

A culture started with 5000 bacteria after three hours it grew 6500 bacteria predict how many bacteria will be present after 13

charle [14.2K]

Answer:

15595 bacteria will be present after 13 hours.

Step-by-step explanation:

Continuous population growth:

The continuous population growth model, for the population after t hours, is given by:

$P(t) = P(0)e^{rt}$

In which P(0) is the initial population and r is the growth rate.

Started with 5000 bacteria

This means that $P(0) = 5000$

$P(t) = 5000e^{rt}$

After three hours it grew 6500 bacteria:

This means that $P(3) = 6500$ . We use this to find r.

$P(t) = 5000e^{rt}$

$6500 = 5000e^{3r}$

$e^{3r} = \frac{65}{50}$

$\ln{e^{3r}} = \ln{\frac{65}{50}}$

$3r = \ln{\frac{65}{50}}$

$r = \frac{\ln{\frac{65}{50}}}{3}$

$r = 0.0875$

$P(t) = 5000e^{0.0875t}$

How many bacteria will be present after 13 hours?

This is P(13). So

$P(13) = 5000e^{0.0875*13} = 15594.8$

Rounding to the nearest whole number

15595 bacteria will be present after 13 hours.

Solve the expresssion x − 5 = 17

CaHeK987 [17]

Answer: x = 22

Step-by-step explanation:

We must isolate the x by itself.

We need to add 5 to both sides of the equation so it cancel out from the side with x.

So x = 22
