Is the expression polynomial ?
allochka39001 [22]

Short answer. No it is not. A polynomial consists of more than 1 term which cannot be combined by either addition or subtraction. Actually most experts say that it must have more than 2 terms. So here is an example of a polynomial.

2x + 3y + 2z. You can't make this any simpler.

2x^3 + 3x^2 + 6x is also a polynomial. Don't get caught by saying it is not and that the terms can be combined in some way. They can't.

3x^2 + 7x^2 is not a polynomial. The x^2 are the same and therefore you can add the 3 and 7 together.

10x^2 is you answer.

In another country, a road sign reads "80 kilometers to the next gas station". How far is that distance to the nearest mile?
rosijanka [135]
1 km = 0.621371 miles
80 * 0.621371 = 49.7097 miles

which is about 50
therefore your answer is B: 50 miles

1. Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds. SOLUTI

<h3>✒️ACCELERATION</h3>

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

\large\sf\underline{Problem:}

Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds.

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

\large\sf\underline{Answer:}

\qquad \qquad \huge \rm = 0.8 \: m/s²

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

\large\sf\underline{Solution:}

Here we have a given of,

  • \tt{(12\:m/s) \:= \:V_f = (final\: velocity) }
  • \tt{(4\:m/s)\:=\:V_i = (initial \: velocity) }
  • \tt{(10\:sec) \:=\:T = (elapsed time) }

\bold{Formula\:||\: Acceleration = \frac{v\: - \:v_0}{t} = \frac{ΔV}{ΔT} }

Because acceleration has a direction <u>(</u><u>riding her bicycle in a straight line</u><u>)</u>, it is important to always subtract the final velocity represented as \bold{V_f} from your initial velocity also represented as \bold{V_i}.

Now 'Work it out' and solve for Acceleration of riding her bicycle using the given formula.

  • \large\rm{A = \frac{V_f \:- \:V_i}{T} }
  • \large\rm{A = \frac{(12\:m/s\:-\:4\:m/s) }{10\:sec}}
  • \large\rm{A = \frac{ 8\:m/s}{10\:sec} }
  • \large\rm{A = 0.8\:m/s²}

Hence, The total acceleration of the girl riding her bicycle is 0.8 meters per second squared (m/s²).

Identify two additional values for x and y in a direct variation relationship where y =11 when x=18
Ann [662]
In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.

So, you can find multiple values that meet this:

y = kx => k = y / x = 11 / 18

=> y = (11/18)x

Now you can give any value to x and fint the value of x that satisfy the relationship:

x           y = (11/18)x

1           11/18

2           11/18 * 2 = 11/9

18          11/18 * 18 = 11

36           11/18 * 36 = 22

So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x
