Many U.S employees received a 3% raise in 2012. Suppose an employee made $47,000 in 2011 and received a 3% raise. What did she m

Hoochie [10]

First lets get 3% into decimal form.

3% is 3/100 = 0.03

Now multiply 0.03 by 47000 to get how much extra money she was going to get.

47000 * 0.03 = 1410

Now we just add
47000 + 1410 = 48410 is what she was going to make in 2012

Another way to do this is

(47000)(1+0.03) = 48410

you would use (1+0.03) which tells you she increased in pay.

What are the zeros of the function defined by 2x + 11x- 6?

asambeis [7]

Note --> As you're writing 'zeroes' , I assume there is a typing mistake and you've given a Quadratic equation in the question

$f(x) = 2 {x}^{2} + 11x - 6 \\ \\ f(x) = (2x - 1)(x + 6) = 0$

Hence , the roots are 1/2 and -6
The graph attached confirms the same ,
