The answer is : So What you basically need to do is circle and fill over 0 and 4. The answer would be C. A and B are wrong you need to look out for the signs basically. Hope this helps

Domain of function f(x) is 0 ≤ x ≤ 4.
Now look at the domain of graphs A - D.

A) Domain 0 ≤ x < 4 (empty circle for x=4) so answer A is wrong.
D) The same as A but for x=0 (empty circle) so domain is 0 < x ≤ 4.
B) Here we have 0 ≤ x < 5 so B is also a wrong answer.
C) Correct one (0 ≤ x ≤ 4)

Verdich [7]
ANSWER

3840 {ft}^{3}

EXPLANATION

The room represents a rectangular prism or a cuboid.

The dimensions of the room are 30 feet by 16 feet by 8 feet(height).

The volume of a rectangular prism is

= base \: area \: \times \: height

Substitute the given values

= 30 \times 16 \times 8 {ft}^{3}

Simplify:

= 3840 {ft}^{3}

Hence the cubic feet of air in the room is 3,840ft³.

What is the factorizaion of the polynomial graphed below? assuming it has no constant factor.​
Oxana [17]

Answer:

y = 0.96(x -√5)(x + √5).

Step-by-step explanation:

The two zeros of this polynomial are (0, 0) and (5, 0), and the vertex is (2.5, -6), all of this info readily available from the graph.

The standard equation of a vertical parabola with vertex at (h, k) is

y - k = a(x - h)^2, where the vertex is represented by (h, k).  Since we know that the vertex is (2.5, -6), the equation for the given graphed parabola is

y + 6 = a(x - 2.5)^2

Since the graph of this parabola goes through the origin, (0, 0), the following must be true if we substitute 0 for both x and y:

0 + 6 = a(0 - 2.5)^2, or 6 = a(6.25).  Thus, a = 6/6.25, or a = 0.96.

The equation of this polynomial must then be:

y + 6 = 0.96(x - 2.5)^2, which is satisfied by both (0, 0) and (5, 0).

This equation can be rewritten as

y = 0.96(x^2 - 5x + 6.25) - 6 = 0.96x^2 - 4.8x + 6 - 6, or just

y = 0.96x^2 - 4.8x.  We must factor this.  Factoring out 0.96, we get:

y = 0.96(x^2 - 5), which can be factored further:  

y = 0.96(x -√5)(x + √5).  This is the fully factored form of the polynomial.

Answer:

Step-by-step explanation:

<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>

<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!

Wavelength (lambda) = Velocity (v) ÷ Frequency ( sec^{-1} or Hz )

f = v / (lambda)

f = 3 / 2 = <em>1.5 (Hz)</em>

<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>
