She is starting at 4000, so that is the y-intercept of the graph. She is descending at 40 feet per minute, so her rate of change or slope is -40. The graph would look like this:
The result after combining like terms is: 
Step-by-step explanation:
Given expression is:

The like terms are those terms with whom the variable or product of variables is same.
As in the given expression, first and third, both terms have x^2y so both terms are like terms
Combining like terms, means the indicated operation is performed on them
So,
Combining like terms:

Hence,
The result after combining like terms is:

Answer:
Step-by-step explanation:
let r be radius of the cylinder.
volume of cylinder=πr²h
1728π=πr²×12
r²=1728 π/12π=144
r=√144=12
diameter=2r=2×12=24 cm
Answer:
D.f(x)=2x-9and g(x)=X+9/2
Answer:
The answer is E
Step-by-step explanation:
We first are going to look at our first term on the table(the number that comes up first) which is $75.
Then we have to find the common factor. So, you divide the second number by the first number( 88.50 divided by 75 which gets us 1.18).
<em>Now, since we found the first term and the common factor, we are going to have to find the exponent for our f(x) equation. </em>
<em>We know that she bought the painting in 2009! Now the problem is asking how much the painting will cost in 2030. So, you will subtract 2030-2009 which gets you 21! So 21 is your exponent!</em>
<em>Equation: </em><em> F(x)= 75(1.18) ^21 </em>
<em>The answer that you get is: $2424.28</em>
