Answer:

Salary before pay raise = 43,478.26 (approx)

Step-by-step explanation:

Given that:

Janice new salary = 45,000

Pay raise = 3.5% = 0.035

Let the previous pay be x

Now according to given conditions:

0.035* x = 45,000 - x

Adding x on both sides we get:

0.035 x + x =  45,000 - x + x

1.035x =  45,000

Dividing both sides by 1.035 we get:

1.035/1.035 x =  45,000/1.035

x = 43,478.26

So, the salary before pay raise was 43,478 approx

proof:

Raise in salart = 3.5% of 43,478.26 = 1,521.74

New salary = old salary + raise in salary

New salary = 43,478.26 + 1,521.74

New salary = 45,000

Hence proved.

I hope it will help you!

I'm assuming you mean a 3.5 percent pay rise.

So, Janice current salary is 103.5% of her previous salary:

\dfrac{103.5}{100}x=45000 \iff x = \dfrac{45000\cdot 100}{103.5}=43478.26

Given that f(x) = 2x + 1 and g(x) = the quantity of 3x minus 1, divided by 2, solve for g(f(3)). 5 7 9 10
AlladinOne [14]

The correct answer is 10.

In order to evaluate any composite function, you need to first put the value in for the inside function. In this case f(x) is on the inside along with the number 3. So, we input 3 in for x in f(x).

f(x) = 2x + 1

f(3) = 2(3) + 1

f(3) = 6 + 1

f(3) = 7

Now that we have the value of f(3), we can stick the answer in for the outside function, which is g(x).

g(x) = (3x - 1)/2

g(7) = (3(7) - 1)/ 2

g(7) = (21 - 1)/2

g(7) = 20/2

g(f(3)) = 10

What is the probability of tossing two heads
vodka [1.7K]

Hello!

Each time, there will be a 1/2 chance of tossing a head. Therefore, we multiply our two probabilities.

1/2(1/2)=1/4

Therefore, we have a 1/4 or 25% chance of tossing two heads in a row.

I hope this helps!

What is the equation of g(x)?
Ksenya-84 [330]

Answer:

g(x)=10^{x-3}

Step-by-step explanation:

Notice that function g(x) has the exat shape of function f(x), and it has just be translated to the right by 3 whole units.

Recall that horizontal translations to the right involve subtracting the number of units moved in the translation from the variable "x". therefore, in our case this means:

f(x)=10^x\\g(x)=10^{x-3}
