Answer:

63.5 in

Step-by-step explanation:

For this problem we are going to split this big scary shape into smaller safer shapes.

Triangle.

On this one you need to add the end of the rectangle to the remaing height on the triangle for 5. Then take the height=5 and the width=7, and plug them into the formula for the area of a traingle which is hxw/2

5x7/2=17.5

The area of the triangle is 17.5 in

Long Rectangle.

On this one all you have to do is take the height=2 and the length=11, and multiply them together as that is the formula for the area of a rectangle.

2x11=22

Other Rectangle.

Again just do the same as the last one but instad with the height as 4 and the length as 6.

4x6=24

Total.

Then just add all those together for the total area!

17.5+22+24=63.5

63.5 in is the total area of this shape!

What is a cubic polynomial function with zeros 3,3 and -3? show your work.​
Brums [2.3K]

Answer:

Cubic polynomial function with zeros 3,3 and -3 is \mathbf{x^3-3x^2-9x+27=0}

Step-by-step explanation:

We need to find a cubic polynomial function with zeros 3,3 and -3.

If zeros of polynomial are: 3,3,and -3

we can write:

x=3, x=3, x=-3

Or

We can write:

x-3=0, x-3=0, x+3=0

Now, we can write them as:

(x-3)(x-3)(x+3)=0

Multiplying the terms, we can find the polynomial:

(x-3)(x-3)(x+3)=0\\(x(x-3)-3(x-3))(x+3)=0\\(x^2-3x-3x+9)(x+3)=0\\(x^2-6x+9)(x+3)=0\\x(x^2-6x+9)+3(x^2-6x+9)=0\\x^3-6x^2+9x+3x^2-18x+27=0\\x^3-6x^2+3x^2+9x-18x+27=0\\x^3-3x^2-9x+27=0

So, cubic polynomial function with zeros 3,3 and -3 is \mathbf{x^3-3x^2-9x+27=0}

PLZZZZ answer correctly!! it's IMPORTANT!!
lara [203]

This is what I got and hopefully it helps.

1.A The dot is not filled and it points in the left direction

2.B The dot is filled and it points to the left

3.A The dot is not filled and it is pointed in the left direction

4.C The dot is filled and is pointing in the right direction.

Whenever you have a filled dot it will always be a greater than or equal to or less than or equal to. When the dot is not filled, the answer will always be greater than or less than.

If alpha beta are the roots of the equation
Vikki [24]

Answer:

Step-by-step explanation:

Hello, I believe that we can consider a different from 0.

By definition of the roots we can write.

ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\ \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }

Thank you

Brittany has a gift box in the shape of a cube. Each side of the box measures 15 cm. what is the volume of the gift box?
miss Akunina [59]
The formula for the volume of a cube is:

v=s³

Where v=volume and s=the length of a side

Since we know that the length of a side of the gift box is 15cm, we can solve for the volume.

v=15³=3375cm³

Answer: V=3375cm³
