3x² + 8x - 4=0<br> Use the quadratic formula to solve the equation
Lisa [10]

Answer:

x=4/14

Step-by-step explanation:

step one:

3x^2+8x-4=0 turns into -

6x+8x-4=0

Step two:

6x+8x-4=0 turns into -

14x-4=0   because you have to combine like terms

Step three:

14x-4= 0 turns into

14x=4 to get x by itself

Step four:

14x=4 turns into -

x=4/14

You roll two fair dice, one green and one red. (a) Are the outcomes on the dice independent? Yes No (b) Find P(1 on green die an
ASHA 777 [7]

Answer:

a

  Yes

b

 P(1 \& 5) = \frac{1}{36}

c

 P(5 \& 1) = \frac{1}{36}

d

 P(5 \& 1 | 1\& 5  ) = \frac{1}{18}

Step-by-step explanation:

From the question we are told that

     Two fair dice, one green and one red were rolled

Generally the  outcomes on the dice independent because the outcome on the first dice is not affected by the second die

Generally the  probability of getting a 1  on a dice rolled is  P(1) =  \frac{1}{6}

the  probability of getting a 5 on a dice rolled is  P(5) =  \frac{1}{6}

Generally the probability of P(1 on green die and 5 on red die) is mathematically represented as

         P(1 \& 5) = \frac{1}{6}  *\frac{1}{6}

         P(1 \& 5) = \frac{1}{36}

Generally the probability of P(5 on green die and 1 on red die) is mathematically represented as

          P(5 \& 1) = \frac{1}{6}  *\frac{1}{6}

         P(5 \& 1) = \frac{1}{36}

Generally the probability of P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) is mathematically represented as

          P(5 \& 1 | 1\& 5  ) = \frac{1}{36} + \frac{1}{36}

         P(5 \& 1 | 1\& 5  ) = \frac{1}{18}

for every one rotation a small gear takes, the larger gear makes 1/6 of a rotation. If the gear makes 10 complete rotations, how
Vika [28.1K]

Answer:

Step-by-step explanation:

1 and 2/3 rotations. The little gear full rotation is equal to 1/6 of the big gears rotation. So if the big gear rotates once then its equal to 6 of the small rotations the extra 4 of the 10 rotations then becomes 4/6 of the big gears rotation or if simplified further, 2/3. This is my way of solving these questions

Please help guys! Using the function f(x) = 3x – 5, what would the output be for an input of 4?
Lelechka [254]

Answer:

Output = 7

Step-by-step explanation:

Input value...is the value of x and the output value..is the value of y,

So the question is just saying that what is the value of y when x = 4

; 3(4) - 5

; 12 - 5

; y = 7...therefore the output value = 7
