Answer:

a=2.5

Step-by-step explanation:

3a-2.4=5.1 Add the like terms ( plus 2.4 cancels out -2.4)

+2.4 +2.4

3a=7.5 Now divide by 3

/3 /3

a=2.5

Ab - bc+ ac, bc - ca+ ab, ca - ab-2bc

BabaBlast [244]

Answer:

$ab-2bc+ca$

Step-by-step explanation:

Complete question is given below

Add:-

ab-bc+ac,bc-ca+ab,ca-ab-2bc

We have to find the result after addition

Now, adding all expression

We get

$ab-bc+ac+bc-ca+ab+ca-ab-2bc$

Combine like terms then, we get

$(ab+ab-ab)+(bc-bc-2bc)+(ac-ca+ca)$

$ab-2bc+ca$

Hence, $ab-bc+ac+bc-ca+ab+ca-ab-2bc=ab-2bc+ca$

Which statement best describes Marcos equation

satela [25.4K]

Marco's equation is correct. Cosine is an even function, which means that for every x, f(-x) = f(x). In other words, you get the same answer for a negative value that you would for its corresponding positive value.

The volume of the solid of revolution is approximately 37439.394 cubic units.

<h3>How to find the solid of revolution enclosed by two functions</h3>

Let be $f(x) = e^{\frac{x}{6} }$ and $g(x) = e^{\frac{35}{6} }$ , whose points of intersection are $(x_{1},y_{1}) =(0,1)$ , $(x_{2}, y_{2}) = (35, e^{35/6})$ , respectively. The formula for the solid of revolution generated about the y-axis is:
