If f(x) = 2x+1; Prove f(3+1) =f(3)+f(1)
Proof: 2(3+1)+1 = 2(3)+1 + 2(1)
6+2+1 = 6+1+2
9 = 9
<span>Therefore: f(3+1) =f(3)+f(1)

this is NOT the answer just a question i got on my test its a example</span>

Can someone help me with 16 and 20? If you’re supposed to write a contrapositive and inverse, but the word not is already in the

Since 2 'not's cancel out, 16's contrapositive is 'If the light will go on, then the fuse has not blown'. In addition, the inverse would be 'If the fuse has not blown, then the light will go on'. I challenge you to do 20 using this information!

Answer:

a. (3x^4 + 6 ) + (2x^2)

b. (X^3 ) + (-x -7)

c. (4.6x^4) + (-1.5x^2)

Step-by-step explanation:

For the first one, we have to write to polynomials, which equal 3x^4 + 2x^2 +6

One possible solution is (3x^4 + 6 ) + (2x^2)

For b, we can do,

(X^3 ) + (-x -7)

And finally for c, we can write,

(4.6x^4) + (-1.5x^2)

Answer:

2444

Step-by-step explanation:

The total cost is the integral of the marginal cost.

$\displaystyle C=\int_{144}^{625}{\dfrac{94}{\sqrt{x}}}\,dx=\left. 2\cdot 94\sqrt{x}\right|_{144}^{625}=188(25 -12)=\boxed{2444}$

The total cost of producing units 144 through 625 is 2444.
