What does f(x) mean?

1 answer:

6 0

The output f(x) is sometimes given an additional name y by y = f(x). The example that comes to mind is the square root function on your calculator. The name of the function is \sqrt{\;\;} and we usually write the function as f(x) = \sqrt{x}. On my calculator I input x for example by pressing 2 then 5.

Isaac is 3 years older than Rachael. In 4 years the sum of their ages will be 75. How old is Isaac now?

MatroZZZ [7]

Answer:

36 years old

Step-by-step explanation:

let x = age of Rachael

2x+3 = current ages combined

[(2x+3)+4]+4 = 75

2x+11 = 75

2x = 75-11

2x = 64

x = 32

Rachel is 32 years old. Isaac is 3 years older, which is 35 years old.

Suppose $24,000 is deposited into an account paying 7.25% interest, which is compoundedcontinuouslyHow much money will be in the

ozzi

Answer:

$49560

Explanations:

The amount deposited is the principal

The principal, P = $24,000

Interest rate, r = 7.25% = 7.25/100 = 0.0725

Time, t = 10 years

Since the interest is compounded continuously, the amounte^ formula is given as:

$A\text{ = P}\times\text{e}^{rt}$

Substitute P = 24000, r = 0.0725, and t = 10 into the formula above:

$\begin{gathered} A\text{ = 24000}\times e^{0.0725(10)} \\ A\text{ = 24000}\times e^{0.725} \\ A\text{ = }24000\text{ }\times\text{ }2.065 \\ A\text{ = }49560 \end{gathered}$

$49560 will be in the account after 10 years if no withdrawal or deposit is made
