Karen is riding her bike at 4 miles per hour she wants to show this on a graph what should she draw
Radda [10]
4 mph is a rate, and is represented by a straight line thru the origin with slope 4/1.

Draw a set of coordinate axes and label them t (for time) and d(for distance).
Start with your pencil point at the origin.  Arbitrarily move this point 3 spaces to the right, and from there move it 4 spaces up.  You'll be at (3,4).

Draw a straight line from the origin (0,0) to the point (3,4).

The graph of the function is shown below. The domain of the function is?
KATRIN_1 [288]

Answer:

The answer to your question is below

Step-by-step explanation:

Domain of a function is the complete set of possible values of "x".

In a radical function, domain must be ≥ 0.

Exercise

                      f(x) =  \sqrt{x + 4}

Then

                        x + 4 ≥ 0

                       x ≥ -4

                      Domain is x ≥ -4 or [-4 , ∞)

Which polynomial is prime?<br> O x²+x+1<br> O x²-x-2<br> O x²-12x + 11<br> Ox²+2x-8
kaheart [24]

Answer:

The correct answer is x^2 + x + 1.

Step-by-step explanation:

A prime polynomial is one that cannot be factored. To solve this problem, we can use the process of elimination by eliminating all answer choices that can be factored.

x^2 - x - 2 = (x - 2)*(x + 1)

x^2 - 12x + 11 = (x - 11)*(x - 1)

x^2 + 2x - 8 = (x + 4)*(x - 2)

Since we cannot factor x^2 + x + 1, and we can factor all of the other answer choices, we know that x^2 + x + 1 is the answer.

Hope this helps!

A typical large orb spider has a mass of 0.50
romanna [79]
The tensile strength of spider silk is about 1150 MPa, which is 1.15 x 10^9 N/m². 

<span>So given that the diameter of the spider silk is 0.15 mm or 1.5 x 10^-4 m. The cross sectional area is approximately: </span>

<span>A = πr² = (3.14)(1.5 x 10^-4 / 2)² = 1.767 x 10^-8 m² </span>

<span>So this means that the amount of force we can apply before the the silk thread is broken is: </span>

<span>F = PA = (1.15 x 10^9)(1.767 x 10^-8) = 20.32 N </span>

<span>F = mg, so m = F/g = (20.32)/(9.81) = 2.07 kg!!! </span>
