NO because 3/5 is the same as 0.6

No, because 3/5 as a decimal is .6 and not 3.5.

Determine the domain of the function, and choose the correct interval and inequality notations,
pickupchik [31]

Answer:

<u></u>

  • <u>See below</u>

Explanation:

Determining the <em>domain</em> of the function P(x) = 2x + 8 is very trivial and does not require the uses of separate intervals.

The domain of a function is the set of input values (x) for which the function is defined. Thus, the domain of P(x) = 2x + 8 is all the real number, which in interval notaion is:

  • (- ∞, ∞)

The symbol ∞ is used to indicate that there is not limit for the value of x: it can goe from any negative number to any positive number).

For didactic purposes let's determine the domain of the function

P(x) = 2/(x+8).

In this case, the function is not defined when the denominator equals 0.

Then, the domain excludes the values for which x + 8 = 0.

  • x + 8 = 0 ⇒ x = - 8.

Then, the solution is all the real numbers different to - 8.

In <em>interval notation</em> it is:

  • (- ∞, -8) ∪ (-8, ∞)

In form of <em>inequaliy</em> that is:

  • x < - 8 ∪ x > - 8

That means, all the real numbers less than - 8 and all the real numbers greater than 8.

What is the volume rounded to the nearest whole number?
Semenov [28]

Answer:

13 in³

Step-by-step explanation:

This is a skewed pyramid, but that doesn't change the way you find the volume of the figure.

The formula for the volume of a pyramid is 1/3(b)(h)

Multiply 6 by 6.5 to get 39, then divide it by 3 to get 13 in³

What is the general form of the quadratic with vertex at (2, 3) and passing through the point (5, 12)?
ki77a [65]

The general form of the quadratic with vertex at (2, 3) and passing through the point (5, 12) is x²-4x+7.

<h3>What is the vertex form of a quadratic equation?</h3>

Vertex form of the quadratic equation is used to find the coordinate of vertex points at which it crosses its symmetry.

The standard equation of the vertex form of quadratic is given as,

y=a(x-h)^2+k

Here, (h, k) is the vertex point.

The vertex of quadratic at (2, 3) and passing through the point (5, 12). Put the value of vertex point in the above equation,

y=a(x-2)^2+3

As the quadratic passes through the point (5, 12). Thus, put the value of this point,

12=a(5-2)^2+3\\12-3=a(3)^2\\9=a\times9\\a=\dfrac{9}{9}\\a=1

Put the value of <em>a</em> in the above expression,

y=1(x-2)^2+3\\y=(x-2)^2+3\\y=x^2-4x+4+3\\y=x^2-4x+7

Thus, the general form of the quadratic with vertex at (2, 3) and passing through the point (5, 12) is x²-4x+7.
