Answer:

Step-by-step explanation:

n is the number of times the interest compounds per year. If the interest in this problem only compounds once per year ("annually"), then n = 1 and you'd be just as well off to use the formula:

$A=P(1+r)^t$

When n = 1, r/n is just r. But I'll show you using the formula they want you to use; it's the same anyways.

For us, P = 500, r = .015, n = 1. Filling that into the formula:

$A=500(1+(.015)/(1))^((1)(t))$ which simplifies down to

$A=500(1+.015)^t$ and

$A=500(1.015)^t$ (see what I meant about not having to use the formula with "n" in it if n 1?)

That formula is the answer to part a. For part b, we are to find how long it takes for the account to reach $800. $800 goes in for A:

$800=500(1.015)^t$

Begin by dividing both sides by 500 to get:

$1.6=(1.015)^t$

The only way to bring that t down from its current exponential position is to take the natural log of both sides. I will do that and at the same time apply the power rule for logs which says the exponent will come down out in front of the log:

$ln(1.6)=tln(1.015)$

Divide both sides by ln(1.015):

$(ln(1.6))/(ln(1.015))=t$

Do this on your calculator to find that

t = 31.5 years

The ratio of men to women in a certain factory is 3 to 4. There are 222 men. How many workers are there?

Answers

The ratio of men to women in a certain factory = 3:4
The total number of men in the factory = 222
Let us assume the common ratio to be = x
Then
3x = 222
x = 222/3
= 74
Then
The total number of women workers in the factory = 4 * 74
= 296
So
The total number of workers in the factory = 296 + 222
= 518
From the above deduction we can easily conclude that there are a total of 518 workers in the factory.

Evaluate : 5-3(x-1) when x=7

Answers

The value of 5-3(x-1) when x=7 is -13.

What is Evaluate meaning?

Evaluation is nothing but to solve an algebraic expression means to find the value of an expression by replacing the value of the variable in it.

To evaluate the expression value, we simply substitute the variable from its given value and simplify the expression by using order of operations.

In our case, the given expression is:

5-3(x-1)

Substitute the given number i.e., 7 for the variable in the expression:

5-3(7-1)

Solve the bracket first:

5-3(6)

Now solve the multiplication part:

5 - 18

Finally Subtract 5 from -18, we get:

-13

Hence the final value of the expression is -13 at x=7.
