What is the square root of 16x36?<br><br> 4x6<br> 4x18<br> 8x6<br> 8x18
Ksenya-84 [330]
To obtain the square root of 16x^36, the coefficient portion (16) will not present any problems since 16 is a perfect square. However, for a variable with an exponent, the exponent is to be multiplied by 1/2 since the square root symbol is equal to raising the term inside to the power of 1/2. This is shown below:

sqrt (16 x^36) = 4 * x^36(1/2) = 4 * x^18

Therefore, the correct answer is 4x^18.

59 points on this! Pls answer
joja [24]

Answer:

(a) y = -4x + 4   (b) y = 2x + 3

<u>solving steps:</u>

note: m refers to slope and y₁ to y point and x₁ to x point

a)

coordinates: (2,-4)

slope: -4

equation:

  • y - y₁ = m(x - x₁)
  • y - -4 = -4(x-2)
  • y = -4x + 8 - 4
  • y = - 4x + 4

b)

coordinates: (1,5), (-1,1)

slope:  \sf \dfrac{y-y_1}{x-x_1}  

  • \sf \dfrac{1-5}{-1-1}  
  • 2

equation:

  • y - y₁ = m(x - x₁)
  • y - 5 = 2(x - 1)
  • y - 5 = 2x - 2
  • y = 2x - 2 + 5
  • y = 2x + 3

The probability of a chance event is anumber between blank that expresses the likelihood that an event blank occur
Mademuasel [1]

The statements second, Third and Fifth are correct statement related probabilities. which represent the 0.25 indicates an unlikely event and

0.75 indicates a likely event and 0.5 indicates equally likely to occur or not occur.

According to the statement

we have given that the some points related the probability and we ahve to express the correct statement and explain them.

So, We know that the

Probability is a the chance that a given event will occur.

And we know that the

  • A zero probability (0) means that the event is impossible, it will never happen.
  • A one probability (1) means that the event will occur with certainty.

You might split the likelihood in some notorious outcomes:

0: impossible (the event will never happen)

Close to zero (about 0 - 0.3): unlikely (the chances are small)

0.5: even (equal chances of happening and not happening)

Close to 1 (about 0.7 - 1): likely (the changes are large)

1: certain (it is 100% sure that the event will happen)

This means that:

first statement, 0 indicates a certain event, is incorrect.

0.25 indicates an unlikely event (second statement is correct)

0.75 indicates a likely event (third statement is correct)

fourth statement is incorrect (1 does not indicate an impossible event, but a certain event)

0.5 indicates equally likely to occur or not occur (fith statement is correct).

So, The statements second, Third and Fifth are correct statement related probabilities. which represent the 0.25 indicates an unlikely event and

0.75 indicates a likely event and 0.5 indicates equally likely to occur or not occur.

Question:

Given that the Probability of a chance event is a number between zero and one that expresses the likelihood of the event occurring, choose all that are correct.

•0 indicates a certain event

•0.25 indicates an unlikely event

•0.75 indicates a likely event

•1 indicates an impossible event

•0.5 indicates equally likely to occur or not occur.
