For this we first need to know how much watt hours are used in 12 house which we can find by taking 960/2=480 now we just need to take 960*4=3840 and add 480 which gives us are end answer of 4320 watt hours. Enjoy!=)

The answer would be 4,320 watts because 960*4.5=4,320. (The 4.5 came from the amount of days because 12 hours is 1/2 one day)

Can someone check if this is right and correct me if it’s not????

Answer:

No. it is not tangent to the circle ⇒ A

Step-by-step explanation:

In any circle a tangent and a diameter are perpendicular at one end of the diameter

In the attached figure

∵ The line segment drawn from point A is passing through

   the center of the circle

∴ This line segment is a diameter of the circle

∵ If AB is a tangent to the circle at point A

- That means the diameter and the tangent meet each other

  at point A (one end of the diameter)

∴ AB and the diameter are perpendicular at point A

∴ m∠A = 90°

Now let us check if the lengths of the triangle formed a right angle triangle or not by using the inverse of Pythagoras Theorem

<em>In a triangle if the square of the longest side is equal to the sum of the squares of the other two sides, then the triangle is a right triangle at the vertex which opposite to the longest side</em>

∵ 17 is the longest side in the triangle

∵ The other two sides are 10.2 units and 6.8 units

∵ (17)² = 289

∵ (10.2)² + (6.8)² = 150.28

∴ (17)² ≠ (10.2)² + (6.8)²

∴ The triangle can not be a right triangle because the square

    of the longest side is not equal to the sum of the squares of the

    other two sides

∵ ∠A is opposite to the longest side

∴ m∠A ≠ 90°

∴ Line AB is not perpendicular to the diameter at A

∴ Line AB is not a tangent to the circle

the price of an antibiotic in one drugstore is $19.50 and $16.25 in another write the ratio of the prices
damaskus [11]
Remember that ratios are essentially fractions without fraction bars...

If they asked to find the ration of 19.50 to 16.25 you would set them up like so....

19.50 : 16.25      -----> since fractions can be simplified so can ratios in the same manner

the ratio you would end up with is <u>6 : 5</u><u />   

Ratios can be easily remembered and solved if you understand the link between them and fractions. 

I hope this helps! :D

In a casino, the chance of winning a certain game is 14.5%. If you play the game 20 times, what’s your best estimate for the num
EleoNora [17]
Expected number of wins=number of plays times the probability of winning

w=20(14.5/100)

w=20(0.145)

w=2.9

w≈3 

So you would expect to win 3 times out of 20 attempts (rounded to the nearest whole number of wins)

Answer:

  1. (f×g)(x) = 2x^2 +2x
  2. (f×g)(x) = 6y^2 -11y -35

Step-by-step explanation:

The distributive property applies.

1. (fg)(x) = f(x)·g(x) = (2x)·(x +1)

  (f×g)(x) = 2x^2 +2x

__

2. (fg)(x) = f(x)·g(x) = (2y -7)·(3y +5) = 2y(3y +5) -7(3y +5)

  (f×g)(x) = 6y^2 -11y -35

_____

<em>Additional comment</em>

Please note in problem 2 that the function argument is x and the variable in the given expressions is y. This means the function value is exactly and only <em>6y^2 -11y -35 for any value of x</em>. It does not change when x changes. (We suspect a typo.)
