What is 772,000 written in scientific notation?
SashulF [63]

When using scientific notation, the number (that is not 10 to the nth power) is always between 1 and 10.

For 772,000.0, I've added the decimal to the correct place. In order to get a number between 1 and 10, we will need to move the decimal 5 places. This leaves us with 7.72 x 10^5.

But, as I see that the answer above is not an option, and the only correct answer would be A, It is the only one between 1 and 10, I feel that there may be a mistake. For A to be correct, the original number would be 7,720,000,000.

Best answer: A

Hope this helps!! :)

Question 2 Determine if (x-3) is a factor to the polynomial P(x) = 2x³ +5x²-28x - 15. (3 marks)​
tangare [24]

Answer:

(x - 3) is a factor of P(x)

Step-by-step explanation:

if (x - 3) is a factor of P(x) then P(3) = 0

P(3) = 2(3)³ + 5(3)² - 28(3) - 15

      = 2(27) + 5(9) - 84 - 15

      = 54 + 45 - 99

      = 99 - 99

      = 0

since P(3) = 0 then (x - 3) is a factor of P(x)

If A and B are independent events, P(A and B) =​
Sergio039 [100]

Answer:

<u>If A and B are independent events, P(A and B) =​ P (A) * P (B)</u>

Step-by-step explanation:

Let's recall that independent events means that when one event occurs, it has no impact or influence on the probability of another event occurring. Here’s an example. Let’s say that we have two events, A and B.  

Event A : it rains in Seattle

Event B : the Super Bowl match is cancelled in Miami

The two events are independent; if it rains in Seattle, this will have no impact on the probability that the Super Bowl match is cancelled in Miami. Raining in Seattle and the cancellation of the Super Bowl are independent events, therefore:

<u>P(A and B) =​ P (A) * P (B)</u>

Triangle ABC is such that AB = 3cm , BC = 4cm , angle ABC = 120 and BAC = theta : Write down in terms of theta , and expression
lakkis [162]
1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.

x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
