Answer:

3. None of the other answers are correct.

Step-by-step explanation:

The statement has a mistake. Correct form is presented below:

<em>Which option best describes the polynomial </em>f(x) = 2\cdot x^{3} - 7\cdot x + 1<em>? </em><em>1)</em><em> Second degree trinomial, </em><em>2)</em><em> Fourth degree polynomial, </em><em>3)</em><em> None of the other answers are correct, </em><em>4)</em><em> Fifth degree monomial, </em><em>5)</em><em> Third degree binomial.</em>

The degree of the polynomial is determined by the maximum exponent of a monomial contained within the algebraic expression, whereas the nature of the polynomial is defined by the number of monomials inside the expressions. In a nutshell, f(x) = 2\cdot x^{3} - 7\cdot x + 1<em> </em>represents a third degree trinomial.

Answer:

Let 7x be the rent paid for backhoe for seven hours.

Step-by-step explanation:

Keyword: maximum amount, the most

    Inequality symbol:  ≤

     (800 × 5) + 7x ≤ 9,000

     4,000 + 7x ≤ 9,000

     7x ≤ 9,000 - 4,000

     7x ≤ 5,000

     7x ÷ 7  ≤  5,000 ÷ 7

     x ≤ 714.29

To the nearest hundreds:

     x ≤ 700

ANSWER:  The maximum rental fee per hour  of backhoe is Php 700.00 (rounded off to the nearest hundreds).

To check if he paid less than 9,000 for the total rent:

    (800 × 5) + (700 × 7) < 9,000

    4,000 + 4,900 < 9,000

    8,900 < 9,000    (True)

What is y=4x^2-9x+1 in vertex form
Anna11 [10]

Answer:

y = 4 \left(x - \dfrac{9}{8} \right)^2 - \dfrac{65}{16}

Step-by-step explanation:

y = 4x^2 - 9x + 1

You need to complete the square on the right side.

y = (4x^2 - 9x) + 1

y = 4(x^2 - \dfrac{9}{4}x) + 1

y = 4 \left( x^2 - \dfrac{9}{4}x + \left( \dfrac{9}{8} \right)^2 \right) + 1 - 4\left( \dfrac{9}{8} \right)^2

y = 4 \left(x - \dfrac{9}{8} \right)^2 + 1 - 4 \left( \dfrac{81}{64} \right)

y = 4 \left(x - \dfrac{9}{8} \right)^2 + 1 - \dfrac{81}{16}

y = 4 \left(x - \dfrac{9}{8} \right)^2 + \dfrac{16}{16} - \dfrac{81}{16}

y = 4 \left(x - \dfrac{9}{8} \right)^2 - \dfrac{65}{16}

Ivenika [448]

Answer:

Step-by-step explanation:

Corresponding angles equal 180 degrees when added

6x + 3x = 180

9x = 180

x = 20

angle CBD is 60 and angle GFH is 120

3(20) = 60

6(20) = 120
