2.11.5                          B.31

Answer: A) 2/3 * 24/1 = 2/1 * 8/1 = 16/1 = 16

 B) 20 = -B/0.2  

 20 * 0.2 = 4

 C) The distance between the two points is 20, if the point for a is 16, and the distance for b is 4, you would have to add those two together and get 20.

The factored form of the related polynomial function is    [tex](x-1)(x+7).[/tex]

Polynomial function is a function that involves non-negative integer powers or positive integer exponents of a variable in an equation like the quadratic equation, cubic equation.

We have,

In the graph given in question, we can see that [tex]x-[/tex]intercepts the axis twice.

And graphs behave differently at various [tex]x-[/tex]intercepts. Sometimes the graph will cross over the [tex]x-[/tex]axis at an intercept and other times the graph will touch the [tex]x-[/tex]axis and bounce off.

Now, in graph;

The [tex]x-[/tex]intercept at [tex]x=1[/tex], i.e. the solution of the [tex]x-1=0[/tex] and passes through the axis.

Now,

The [tex]x-[/tex]intercept at [tex]x=7[/tex]  is the solution of [tex]x-7=0[/tex] and again passes through the axis.

So, from the above statements we can say that the factored form of the related polynomial is [tex](x-1)(x+7).[/tex]

Hence, we can say that the factored form of the related polynomial function is    [tex](x-1)(x+7).[/tex]

Given:

The equation is

[tex]y=5x^3-6x^2-4x+8[/tex]

To find:

The coordinates of the turning point.

Solution:

We have,

[tex]y=5x^3-6x^2-4x+8[/tex]

Differentiate with respect to x.

[tex]\dfrac{dy}{dx}=5(3x^2)-6(2x)-4(1)+(0)[/tex]

[tex]\dfrac{dy}{dx}=15x^2-12x-4[/tex]

For the turning points [tex]\dfrac{dy}{dx}=0[/tex].

[tex]15x^2-12x-4=0[/tex]

Using quadratic formula:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\dfrac{-(-12)\pm \sqrt{(-12)^2-4(15)(-4)}}{2(15)}[/tex]

[tex]x=\dfrac{12\pm \sqrt{144+240}}{30}[/tex]

[tex]x=\dfrac{12\pm \sqrt{384}}{30}[/tex]

Now,

[tex]x=\dfrac{12+\sqrt{384}}{30}\text{ and }x=\dfrac{12-\sqrt{384}}{30}[/tex]

[tex]x\approx 1.053\text{ and }x\approx-0.253[/tex]

Putting x=1.053 in the given equation, we get

[tex]y=5(1.053)^3-6(1.053)^2-4(1.053)+8[/tex]

[tex]y\approx 2.973[/tex]

Putting x=−0.253 in the given equation, we get

[tex]y=5(-0.253)^3-6(-0.253)^2-4(-0.253)+8[/tex]

[tex]y\approx 8.547[/tex]

Therefore, the turning points are (1.053,2.973) and (-0.253, 8.547).

Step-by-step explanation:

Answer:

497 inches²

Step-by-step explanation:

Hi!

I have never done a problem like this in my life but I see exactly how it is meant to be solved. Lets try it out.

Let us first remind ourselves of the formulas we need for this.

Formula for a circle and the formula for a triangle.

Circle :

A = [tex]\pi[/tex] x r²

(or Area = pi x radius²) (Note that [tex]\pi[/tex] = 3.14)

Triangle :

A = b x h x 1/2

(or Area = base x height x 1/2)

Now lets see what the question wants from us and what we are given :

Gives us :

Diameter XY = 30 inches

YZ = 20 inches

XZ = 21 inches

And it wants the total area of the shaded regions to the nearest square inch. (Inches²)

Alright so first lets solve this triangle :

We need to do Base x Height x 1/2 :

Input your numbers given :

Base = 21in

Height = 20in

And lets multiply this out :

Base x Height x 1/2

21     x    20     x 1/2

21 x 20 gives us 420

Now we have :

420 x 1/2

Note that this is literally saying it wants half of 420. So we can actually just make it easier and do :

420/20

This gives us 210.

Great! Now we have the area of the triangle which is 210, this will be important later but for now lets move onto the circle.

Alright so we need radius to solve this but it really doesn't give us much about the circle.

But...

If you take a look at ∠YX you can see that it says 30in. This is actually the diameter of the circle and we can use this to find the radius of the circle.

The radius of a circle is 1/2 of the diameter.

And the diameter of a circle is 2 × the radius.

So in this case to find the radius we can actually take the 30inch diameter and divide it by 2 to find our radius.

30/2

=

15

Radius = 15inches!

Now lets look back to our wonderful circle formula.

A = [tex]\pi[/tex] x r²

or if we write it out :

Area = pi x radius²

So now lets plug in the radius we found and then solve to find the area of this circle.

Area = pi x 15²

(Don't forget the tiny 2 next to the 15!)

Now we can multiply this :

pi x 15²

=

706.858347058

Round to the nearest square inch :

707 inches²

(pi = [tex]\pi[/tex])

So now what we have is the area of both shapes. It is smooth sailing from this point on. Let us recap :

Triangle Area = 210 inches²

Circle Area = 707 inches²

Now we have to find the area of the shaded area which is really simple subtraction.

The shaded area is the circle but the triangle is overlapping this shaded area so all we have to do is subtract the triangles area from the circles area so all that will be left is the shaded area of the circle.

So we do :

Circles area - Triangles area = Our answer

707 - 210 = 497

There we go!

Our answer is 497 inches²

This took a minute I am sorry about that but I hope this helps!

Let d be the number of days.

We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.  

We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be: [tex]12n+34[/tex]

As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100.

Answer:

  (a) subscriptions

  (c) vehicle value

Step-by-step explanation:

Exponential functions are used to describe situations where the amount of change is proportional to the amount.

If the amount of change is a constant, then the function is linear.

A. video subscribers change by an amount proportional to their number, so is an exponential function.

B. the change in number of bricks in a row is a constant, so the function is a linear function.

C. The amount of change is proportional to the value, so the function is an exponential function.

D. The change in patient count is a constant, so the function is a linear function.

The set of side lengths that could represent a right triangle is

12 ft, 10 ft, and 8 ft.

Option D is the correct answer.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

To determine which of the given sets of side lengths could represent a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

Using this theorem, we can check each of the given sets of side lengths to see if they satisfy this condition:

6 ft, 5 ft, 4 ft

6² + 5² = 36 + 25 = 61

4² = 16

Since 61 is not equal to 16, this set of side lengths does not represent a right triangle.

8 ft, 7 ft, 6 ft

8^2 + 7^2 = 64 + 49 = 113

6^2 = 36

Since 113 is not equal to 36, this set of side lengths does not represent a right triangle.

10 ft, 8 ft, 6 ft

10^2 + 8^2 = 100 + 64 = 164

6^2 = 36

Since 164 is not equal to 36, this set of side lengths does not represent a right triangle.

12 ft, 10 ft, 8 ft

12^2 + 10^2 = 144 + 100 = 244

8^2 = 64

Since 244 is equal to 64 + 180, this set of side lengths does represent a right triangle.

Therefore,

The set of side lengths that could represent a right triangle is 12 ft, 10 ft, and 8 ft.

Answer:

FD = 8

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{FD}{BA}[/tex] = [tex]\frac{FE}{BC}[/tex] , substitute values

[tex]\frac{x+3}{2x+2}[/tex] = [tex]\frac{16}{24}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )

2(2x + 2) = 3(x + 3) ← distribute parenthesis on both sides

4x + 4 = 3x + 9 ( subtract 3x from both sides )

x + 4 = 9 ( subtract 4 from both sides )

x = 5

Thus

FD = x + 3 = 5 + 3 = 8
