50 POINTS! Plot function h on the graph. NO LINKS

Mathematics
1 answer:
tangare [24]2 years ago
3 0

See attachment for the graph of the piecewise function h(x)

<h3>How to plot the function?</h3>

The function is given as:

h(x) = | -4,    x < 3

         | x + 5,    x >= 3

The above function is a piecewise function.

It has 2 separate functions at two domains

This means that we plot the sub-functions in the piecewise function at their respective domain

See attachment for the graph of the piecewise function h(x)

When a boy pulls his sled with a rope, the rope makes an angle of 70 with the horizontal. If a pull of 16 pounds on the rope is
alexandr1967 [171]

The horizontal component of force is 5.47 lb

<u>Step-by-step explanation:</u>

Given that a boy pulls his sled with a rope.

The rope makes an angle with horizontal = 70 degree

If a pull on the rope is needed to move the sled = 16 pounds

We need to find the horizontal component of force

In given scenario, the force used in this scenario is a vector addition of the horizontal and the vertical force component. The horizontal force component is calculated by multiplying the applied force by the cosine of the angle of the applied force from the horizontal plane in which it is found:                     horizontal force component = applied force x cos 70 degree

Horizontal component force = f \cos \alpha

Here, given applied force, f = 16 pounds

Then, horizontal component of force =  16 \cos 70^{\circ}

Horizontal component of force = 16×0.342

Hence, horizontal component of force = 5.47 lb

Sari is factoring the polynomial 2x2 + 5x + 3. What is the missing number in her factorization?
sergejj [24]

Answer:

<em>The missing number in Sari's factorization is </em><em>3</em><em>.</em>

Step-by-step explanation:

The given polynomial is,

=2x^2 + 5x + 3

From quadratic equations, applying middle term factorization,

=2x^2 + 2x+3x + 3

=2x(x + 1)+3(x + 1)

=(2x+3)(x + 1)

Comparing this to the given expression, the missing number in Sari's factorization is 3.

The concentration of bacteria B in millions per milliliter after x hours is given by B(x)=1.33e^0.15x. After how many hours will
BARSIC [14]

Answer:

21 hours

Step-by-step explanation:

You want to find x such that B(x) = 31. Fill in the value and solve.

... 31 = 1.33e^(0.15x)

... 31/1.33 = e^(0.15x) . . . . divide by 1.33

... ln(31/1.33) = 0.15x . . . . take the natural log

... ln(31/1.33)/0.15 = x ≈ 20.992 . . . . hours

After 21 hours, the concentration will be 31 M/mL.
