Answer 1

Answer:

Answer:

$f(t) = 8400(1.0018)^(12t)$

2.22%

Step-by-step explanation:

$8400 is invested in an account earning 2.2% interest (APR), compounded monthly.

So, the value of the account after t years will be given by

$f(t) = 8400 (1 + (2.2)/(12 * 100) )^(12t) = 8400(1.0018)^(12t)$ {Rounded to the four decimal places} (Answer)

Now, for t = 1 year, f(1) = $8586.67

So, the percentage of growth per year (APY) = $((8586.67 - 8400) * 100)/(8400) = 2.22$ % {Rounded to the nearest hundredth of percent} (Answer)

What value of x will make this proportion true? a. 7 b. 18 c. 24 d. 28 42 3 4 = 14 x 1 2

Answers

We are given proportion as 14/x = 1/2

So first step is to get rid off 2 from denominator,so we multipy both sides by 2

2(14/x) =2(1/2)

28/x =1

Next step is to get rid off x from denominator ,so we multiply both sides of the equation by x

x(28/x) =x(1)

28x/x =x

28 =x

Hence we get value of x =28

So answer is choice d) 28

How do i round 3,176 to the nearest thousand

Answers

Here is the rule: 4 and below let it go (round down), 5 and above give it a shove (round up)
Look to the place after the thousandths in the number 3,176 (the 1)
Since it is below 5, you would round down to 3,000

Well you would look at the 176 in 3,176. Since it is less then half (500) you would round it down. So 3,176 rounded to the nearest thousand would be 3,000
