Answer:

1.you use a "carrot" it looks like this ^ so you put 6^3 an that is saying 6 to the power of 3

2. you can also use the symbols option and there is shows little numbers but only gives you the option for the power of 2 and 3

example: 6³

3. click equation option and put the x^2 and then delete the x and put the number or variable and then within the brackets put what the power should be.

A municipality has budgeted R80 000 for putting up new street name boards The street name boards cost R134 each. How many new st

ivanzaharov [21]

The Municipality we be able to set up 597 street name boards with R2 left in the budget.

Data;

Amount Budgeted = R80,000
Cost of each board = R134

<h3>Number of Street Boards in the Budget</h3>

The number of streets boards that can be produced in the budget is calculated by dividing the total amount budgeted by the cost of each street board. This is done mathematically as

$x = \frac{80000}{134}\\x = 597.01$

We would have a total of 597 street names on the budget with some amount left.

We can calculated this by multiplying 597 by 134 and then subtracting the value from R80,000

$597 * 134 = 79998 \\R80,000 - R79998 = R2$

The Municipality we be able to set up 597 street name boards with R2 left in the budget.

If the growth rate of bacteria at any time t is proportional to the number present at t and triples in 1 week

serg [7]

The population after 20 weeks will be 403.42 $x_{0}$ in which $x_{0}$ is the initial population.

Given that the growth rate of bacteria at any time t is proportional to the number present at t and triples in 1 week.

We are required to find the number of bacteria present after 10 weeks.

let the number of bacteria present at t is x.

So,

dx/dt∝x

dx/dt=kx

1/x dx=k dt

Now integrate both sides.

$\int\limits {1/x} \, dx$ = $\int\limits{k} \, dt$

log x=kt+log c----------1

Put t=0

log $x_{0}$ =0 +log c ( $x_{0}$ shows the population in beginning)

Cancelling log from both sides.

c= $x_{0}$

So put c= $x_{0}$ in 1

log x=kt+log $x_{0}$

log x=log $e^{kt}$ +log $x_{0}$

log x=log $e^{kt}x_{0}$

x= $e^{kt}x_{0}$

We have been given that the population triples in a week so we have to put the value of x=2 $x_{0}$ and t=1 to get the value of k.

2 $x_{0}$ = $e^{k} x_{0}$

2= $e^{k}$

log 2=k

We have to now put the value of t=20 and k=log 2 ,to get the population after 20 weeks.

x= $e^{20log 2}$ $x_{0}$

x= $e^{0.30*2}$ $x_{0}$

x= $e^{6}x_{0}$

x=403.42 $x_{0}$

Hence the population after 20 weeks will be 403.42 $x_{0}$ in which $x_{0}$ is the initial population.

Two more than 5 times a number is greater than or equal to 3 change into numbers

Savatey [412]

Hi there!

FACTS :

"Two more than 5 times à number" means that you add 2 to 5 times a number.

"Greater than or equal" is represented by this sign : ≥

STEPS TO ANSWER:

Let's replace "a number" by the letter "y"

Add 2 to 5 times y, this is greater than or equal to 3.

5 times y = 5y

Add 2 to 5y = 5y + 2

Your inequality is : 5y + 2 ≥ 3

There you go! I really hope this helped, if there's anything just let me know! :)
