Answer:

Step-by-step explanation:

1)  First graph is correct! Because clearly, the roots are visible, and it's a 3rd degree polynomial, so it can't be bottom twos, cuz they're parabolas.

2) Roots are at -6, -2 and 3. (If you need further assistance on this, let me know!) Hence, It is the last graph!

3) Roots are at -4, -2 and 2, (Again, if you need assistance, let me know!)

Hence, it is the first one!

Hope this cleared things up for you!

Answer:

1) The degree of the polynomial function f(x) is 3, because it has three roots when f(x) = 0. Remember that the degree of a polynomial is dictated by the number of roots it has. (first graph)

2) The graph that represents g(x)=x^{3}+5x^{2}  -12x-36 is attached. There you can observe that the roots of this functoin are x=-6, x=-2 and x=3. The right choice is the graph placed at the bottom-right side.

3) The graph of the function f(x)=x^{3}+4x^{2}  -4x-16 is attached. Notice that its roots are x=-4, x=-2 and x=2. Therefore, the right choice is the graph placed at the top-left side.

Suppose you are covering your desk (shape below) with paper and want to know how many square inches of paper you need.
zavuch27 [327]

Answer:

a. Divide the figure into two rectangles, find the area of each rectangle and add them (See the picture attached).

b. 279\ in^2

c. The total area of the figure is 279 square inches.

Step-by-step explanation:

a. Divide the figure into two rectangles (See the picture attached), then find the area of each rectangle and finally, add the areas calculated in order to get the total area of the given figure,

b. The area of a rectangle can be found using this formula:

A=lw

Where "l" is lenght  and "w" is the width.

 Area of Rectangle A

You can identify that:

l_A=19\ in\\\\w_A=11\ in

Then, its area is:

A_A=(19\ in)(11\ in)=209\ in^2

Area of Rectangle B

You can identify that:

l_B=10\ in\\\\w_B=18\ in-11\ in=7\ in

Then, its area is:

A_B=(10\ in)(7\ in)=70\ in^2

Total area

A_T=209\ in^2+70\ in^2=279\ in^2

c. The total area of the figure is 279 square inches.

A window shaped like a parallelogram has an area of 23 4/5 square feet. The height of the window is 2 4/5 feet. How long is the
USPshnik [31]

Answer:

base = 8\frac{1}{2}ft

Step-by-step explanation:

The general formula for the area of a parallelogram is:

A = bh, where b = the length of the base and h = the height

Using the given values for area and height, we can solve for the missing variable of 'b':

23\frac{4}{5}=\frac{119}{5}

2\frac{4}{5}=\frac{14}{5}

\frac{119}{5}=\frac{14}{5}h

Multiply both sides by the reciprocal:

(\frac{5}{14})(\frac{119}{5})=(\frac{14}{5})(\frac{5}{14})h

\frac{119}{14}=h

h=8\frac{1}{2}ft

A department store's survey suggests that 76% of shoppers buy food, 49% buy clothes, and 28% buy both food and
Artyom0805 [142]

Answer:

0.57

Step-by-step explanation:

Given that:

food = f ; c = clothes

P(f) = 0.76

P(C) = 0.49

P(fnC) = 0.28

Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the probability that the shopper also buys food?

P(f Given C) = P(f | C)

P(f | c) = p(fnC) / p(C)

P(f | c) = 0.28 / 0.49

P(f | c) = 0.5714

P(f | c) = 0.57
