Answer:

$\boxed{\sf \ \ \ 3x^2-7x+2 \ \ \ }$

Step-by-step explanation:

Hello,

There are a lot of polynomials which have 2 and 1/3 as zeroes,

I can show you one below

$3(x-2)(x-\dfrac{1}{3})=(x-2)(3x-1)=3x^2-x-6x+2=3x^2-7x+2$

hope this helps

The area of the circle is 3.14 square millimeters

<h3>Calculating Area</h3>

From the question, we are to the area of the circle

The area of a circle can be determined by using the formula,

A = πr²

Where A is the area of the circle

and r is the radius of the circle

From the given information,

r = 1 mm

and π = 3.14

Putting the parameters into the equation, we get

A = 3.14 × 1²

A = 3.14 × 1

A = 3.14 mm²

Hence, the area of the circle is 3.14 square millimeters

The function — is used to model the height of an object projected in the air, where h(t) is the height in meters and t is the ti

MissTica

The answer choice which represents the domain and range of the function h(t) as given in the task content in which case, values are rounded to the nearest hundredth is; Domain: [0, 3.85] and Range: [0, 18.05].

<h3>What are the domain and range of the function as given in the task content?</h3>

It follows from convention that the domain of a function simply refers to the set of all possible input values for that function.

Also, the range of a function is the set of all possible output values for such function.

On this note, by observing the graph in the attached image, it follows that the Domain of the function in discuss is; [0, 3.85].

While the range is the difference between the minimum and maximum height attained and can be computed as follows;

At minimum height, t = 0; hence, h(t) = 0.

At maximum height; h'(t) = 0 where h'(t) = h'(t)=-9.74t+18.75 and hence, t = 1.92.

Hence, h(1.92) = 18.05.

The range is therefore; [0, 18.05].

Please help me almost done

Gnom [1K]

Answer:

x = -8

<XCE = 30

Step-by-step explanation:

Remark

In any question like this, there are 8 possible answers. Of the 8, 4 are acute angles and 4 are obtuse. So any pair are either equal to each other, or they are supplementary. In this case the two given angles are equal.

We have a little bit of both in this question.

Solution

3x + 174 = - 7x + 94 Alternate exterior angles. Add 7x to both sides.

3x+7x +174 = 94 Combine

10x + 174 = 94 Subtract 174 from both sides

10x = 94 - 174

10x = - 80 Divide by 10

x = - 80/10

x = - 8

===================

Check

3x + 174 = -24 + 174 = 150

-7x + 94 = -7*-8 + 94

-7x + 94 = 56 + 94 = 150

<XCE

<XCE = 180 - (3x + 174)

<XCE = 180 - (-24 + 174)

<XCE = 180 - (150)

<XCE = 30

Simplify the polynomial expression given below.<br><br> (2x − 1)(2x2 + 5x + 3) + (3x + 6)

fenix001 [56]

Answer:

$4x^{3}+8x^{2} +4x+3$

Step-by-step explanation:

Hello

To simplify the polynomial we must eliminate the parentheses

by definition

$ax^{n}*bx^{m} =abx^{n+m}$

$(2x-1)(2x^{2} +5x+3)+(3x+6)\\(4x^{3} +10x^{2} +6x-2x^{2} -5x-3)+(3x+6)\\\\We\ add\ the\ similar\ terms\\\\(4x^{3}+8x^{2} +x-3)+(3x+6)\\\\4x^{3}+8x^{2} +4x+3$

I hope it helps

Have a great day
