FILL IN THE BLANKS: Given P(x) = 3x5 + 7x6 + 11x7 – 12x - 10
Mama L [17]

The polynomial  3x^5 + 7x^6 + 11x^7 - 12x - 10 is in standard form if the exponents are arranged in decreasing order.

<h3>Polynomial in Standard Form</h3>

Polynomial is an algebraic expression with one or more terms. For example :2x^3+6x^4+x^2+x+2. In this example and in your exercise the exponents of the terms are not arranged in order.

Um polynomial is in <u>Standard Form</u> when the exponents of the terms are in decreasing order. See more details below.

2x^3+6x^4+x^2+x+2is not in standard form because the exponents are not written in decreasing order.

6x^4+2x^3++x^2+x+2 is in standard form because the exponents are written in decreasing order.

Therefore, the given polynomial will be in standard form if yours exponents are arranged in decreasing order.

How do you find a vector of length 10 in the direction of vequals=left angle 3 comma negative 2 right angle3,−2​?
Kazeer [188]
First we look for the angle of the vector, which will be given by:
 tan (x) = (- 2/3)
 Clearing x we have:
 x = ATAN (-2/3) = - 33.69 degrees.
 Which means that the angle is 33.69 degrees measured clockwise from the x axis.
 Equivalently the angle is
 360-33.69 = 326.31 degrees
 326.31 degrees measured counterclockwise from the x axis.
 The vector is then:
 v = 10 (cos (326.31) i + sin (326.31) j)
 answer
 v = 10 (cos (326.31) i + sin (326.31) j)

Eduardwww [97]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{40}}}}}

Step-by-step explanation:

\sf{50 \: \% \: of \: 80}

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒\sf{ \frac{50}{100}  \times 80}

⇒\sf{ \frac{1}{2}  \times 80}

Divide 80 by 2

⇒\sf{40}

Hope I helped!

Best regards!!
