What is a polynomial expression?

FinnZ [79.3K]

Step-by-step explanation:

a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x2 − 4x + 7.

Answer:

7.9 ft

Step-by-step explanation:

The hypotenuse is the side opposite of the right angle, hence the hypotenuse for this triangle is 11 ft.

Side $x$ is adjacent to the angle given. So we need adjacent and we have hypotenuse. Which trigonometric ratio relates adjacent and hypotenuse? It is COSINE.

<em>Thus, we can write:</em>

$cos(A)=\frac{adjacent}{hypotenuse}\\cos(44)=\frac{x}{11}$

<em>Cross multiplying, we can solve for $x$ :</em>

$cos(44)=\frac{x}{11}\\x=cos(44)*11\\x=7.91$

Rounding to nearest tenth, we have $x=7.9$ ft.

Solve the Inequality: <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B3%7D%20%5Cgeq%20-1" id="TexFormula1" title="\frac{b}{3}

topjm [15]

$\frac{b}{3} \geq - 1 \\ = 3 \times \frac{b}{3} \geq \times ( -1 ) \\ = b \geq3 \times ( - 1) \\ = b \geq - 3 \times 1 \\ \\ = b \geq - 3$

Step By Step Explanation:

Multiply both sides of the inequality by 3
Reduce the numbers with the greatest common factor 3
Multiplying a positive and a negative equals a negative
Any expression multiplied by 1 remains the same

Polygon ABCD is dilated by a scale factor of 2 with the center of dilation at the origin to create A'B'C'D'. If the endpoints of

Sonja [21]

The distance formula is given by $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Take point A(0, -7) as (x₁, x₂) and point B(8, 8) as (y₁, y₂)

Distance AB = $\sqrt{(8-0)^2+(8--7)^2}$
Distance AB = $\sqrt{8^2+15^2}$
Distance AB = $\sqrt{289}$
Distance AB = 17

The line AB is dilated to A'B' by scale factor of 2, it means the length of the line is multiplied by 2

Distance A'B' = 2 × 17 = 34 units
