By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)

<h3>How many more distance does the average race car travels than the average consumer car?</h3>

In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:

s' = (v' - v) · t

Where:

  • v' - Speed of the average race car, in miles per hour.
  • v - Speed of the average consumer car, in miles per hour.
  • t - Time, in hours.

Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:

s' = (210 - 120) · (30 / 3600)

s' = 3 / 4 mi

The distance surplus of the average race car is equal to 3 / 4 miles.

What is the common ratio in the sequence 6,12,24,48,96<br> A -2<br> B 2<br> C 6<br> D 1/2
anyanavicka [17]

The ratio is that of one term to the one before:

... 12/6 = 2

It is "common" because it applies to every pair of adjacent terms:

... 24/12 = 48/24 = 96/48 = 2

The appropriate choice is ...

... B 2

Answer:

Step-by-step explanation:

O

3x² - 11x - 4 = 0

a = 3 ; b = -11 , c = -4

Sum \ of \ roots = \dfrac{-b}{a}=\dfrac{-(-11)}{3}=\dfrac{11}{3}\\\\Product \ of \ roots =\dfrac{c}{a}=\dfrac{-4}{3}\\\\

W

8x² + 12x = -1

8x² + 12x + 1 = 0

a = 8 ;  b = 12 ; c = 1

Sum  \ of \ roots =\dfrac{-b}{a}=\dfrac{-12}{8}=\dfrac{-3}{2}\\\\Product \ of \ roots = \dfrac{c}{a}=\dfrac{1}{8}

L

x² + x = 6

x² + x - 6 = 0

a = 1 ; b= 1 ; c = -6

Sum \ of \ roots = \dfrac{-1}{1}=-1\\\\Product \ of \ roots = \dfrac{-6}{1}=-6

G

x²- 2x - 2 =0

a = 1 ; b = -2 ; c = -2

Sum \ of \ roots = \dfrac{-(-2)}{1}=2\\\\Product \ of \ roots = \dfrac{-2}{1}=-2

E

4x - 5 = -4x²

4x² + 4x - 5 = 0

a = 4 ;  b = 4 ; c = -5

Sum \ of \ roots = \dfrac{-4}{4}=-1\\\\Product \ of \  roots=\dfrac{-5}{4}

B

12x² +x -6 = 0

a = 12 ; b = 1 ; c = -6

Sum \ of \ roots =\dfrac{-1}{12}\\\\Product \ of \ roots  =\dfrac{-6}{12}=\dfrac{-1}{2}

R

2x² + 5x - 25 = 0

a = 2 ; b = 5 ; c = -25

Sum \ of \ roots=\dfrac{-5}{2}\\\\Product \ of \ roots =\dfrac{-25}{2}

A

6x² -5x - 4 = 0

a = 6 ; b = -5 ; c = -4

Sum \ of \ roots =\dfrac{-[-5]}{6}=\dfrac{5}{6}\\\\Product \ of \ roots = \dfrac{-4}{6}=\dfrac{-2}{3}
