The investment growth is an illustration of an exponential function.
It will take 78.3 years for the investment to reach £29437.2
The given parameters are:
- Initial worth: 645.3
- Rate: 0.05
<h3>
Exponential functions</h3>
An exponential function is represented as:

Where:
- a represents the initial value
- r represents the rate.
<h3>
The number of years</h3>
So, we have:

When the investment becomes 29437.2, the equation becomes

Divide both sides by 645.3

Take the logarithm of both sides

This gives

Make t the subject


Hence, it will take 78.3 years for the investment to reach £29437.2

Answer:
210 student's
Step-by-step explanation:
80 students chose the aquarium.
60 students chose the science center.
30 students chose the planetarium.
40 students chose the farm.
The students can't vote for more than one place, so you just add all the numbers together.
80 + 60 + 30 + 40 = 210 students
Answer:
30 square feet
Step-by-step explanation:
Number of tiles used for covering the kitchen floor = 10
Area covered by the floor = 6 * 5 feet^2
= 30 square feet
Length of each tiles = 3 feet
Width of each tiles = w feet
Area covered by each tiles = 3w square feet
Then the equation can be written as
3w * 10 = 30
30w = 30
w= 30/30
= 1 feet
10 *3w = 30
In exponential form 720,080 is:
7 × 10^5
+ 2 × 10^4
+ 0 × 10^3
+ 0 × 10^2
+ 8 × 10^1
+ 0 × 10^0
Answer:
Option 3,4,5 are correct.
Step-by-step explanation:
The system of equations are:

Multiply equation (2) with -3 and add with equation (1)

Value of y is 3
Putting value of y in eq(2)

Value of x is -2
So, Option 3,4,5 are correct.
