sarah invests £9600 at a simple interest rate of 8% per year. Work out the value of the investment after 3 years

Mathematics

andre [41]3 years ago

Answer:

the value of the investment after 3 years=  £11,904

Step-by-step explanation:

sarah invests £9600 at a simple interest rate of 8% per year

number of years = 3

Formula for simple interest

I = P*n* r

P is the initial amount invested= 9600

r is the rate of interest = 8% = 0.08

n = number of years = 3

Now we find interest using formula

I = 9600 * 0.08 * 3= 2304

Interest amount is 2,304

Now we add the interest with the initial amount to get the value of investment after 3 years

9600 + 2304= 11904

Answer: Choice D

======================================================

Explanation:

The formula for the surface area of a cylinder is

SA = 2\pi*r^2 + 2\pi*r*h

We then replace r with 10 and h with 25. Keep in mind that the diameter is 20 mm, so the radius is half that at 10 mm.

So that's how we get to

SA = 2\pi*10^2 + 2\pi*10*25

To find the percentage, ask yourself, how much is 2000 of the original value which is 20350.   This can be solved by the following equation.

2000/20350=

The answer is approximately 0.09828.   Then, convert this to a percent. 9.828%. Then, round it to the nearest percent. The answer is 10%

Consider the function. f(x)= -2/3x-24 Which conclusions can be drawn about f–1(x)? Select two options. f–1(x) has a slope of -2/
disa [49]

Answer:

(D) f^{-1}{(x$) has an x-intercept of (-36, 0).

(E)f^{-1}{(x) has a range of all real numbers.

Step-by-step explanation:

Given the function: f(x)= -\dfrac23x-24

f(x)+24= -\dfrac23x\\$Multiply both sides by $  -\dfrac32\\x=-\dfrac32(f(x)+24)\\f^{-1}(x)=-\dfrac32f(x)-36

When y=f(x)=0

f^{-1}(x)=-\dfrac32(0)-36\\f^{-1}(x)=-36

Therefore, f^{-1}(x)$ has a x-intercept of -36

Also, f^{-1}(x) has a range of all real numbers.

Therefore, Options D and E are correct.
