Ima houseseller earns a 3% commision for selling a house. if he sells a house for $120000, what is his commision

Masja [62]

Commission is earning a certain percentage of the total sold price.

To figure this out we need to find what is 3% of $120,000

We can do this by multiplying 3% and $120,000

First let's change 3% into a decimal.

3% = 0.03

Now lets multiply.

0.03 x $120,000 = $3,600

So this person earned $3,600 in commission.

Good Luck! :)

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.

nadya68 [22]

Answer:

f'(x) $=2(e^4^x)+(x^2+1)(4e^4^x)$

Step-by-step explanation:

The derivative of the function:

$(x^2+1)e^4^x$

The rule for the product of two functions:

f'(x) $=g'(x)h(x)+g(x)h'(x)$

Therefore

g(x) $=x^2+1$

g'(x) $=2$

f(x) $=e^4^x$

f'(x) $=4e^4^x$

f'(x) $=2(e^4^x)+(x^2+1)(4e^4^x)$
