Answer:
P(green then purple)=P(green)*P(purple) since there's replacement.
That's right. The answer is not zero. In fact, there's no answer at all,
simply because there's no question. In math in general, division by zero
is "not permitted", and if people start talking about it, the answer is called
"indeterminate" ... that means vague, and can't be determined.
Division is repeated subtraction. 6 divided by 2 means: "How many times
can you take 2 away from 6 before the 6 is all used up and gone ?", and the
answer is: 3 times and then it's gone.
So the question is really asking: "How many times can you take zero away
from 5 before the 5 is all used up and gone ?". There's no answer, because
no matter how many times you take away zero, you can never use up the 5 .
One more comment on the subject: Save your question marks. One is plenty.
Vertex formula:
y = a ( x - 5 )² - 3
1 = a ( 6 - 5 )² - 3
1 = a - 3
a = 4
Answer:
B ) y = 4 ( x - 5 )² - 3
Since we know that The angle of depression from the airplane to the airport is 40°, and its altitude is 10000 feet, we can create a right triangle using the horizontal of the plane, the angle of depression, and the altitude as one of the legs of our right triangle. the horizontal (ground distance) from the airport to the airplane's<span> will be the same as the adjacent leg of our depression angle. To find the adjacent leg we'll need a trig function that relates our leg with the depression angle and the opposite leg. That trig function is tangent. So lets set up an equation and solve it to find our distance:
</span>
![tan(40)= \frac{10000}{leg}](https://tex.z-dn.net/?f=tan%2840%29%3D%20%5Cfrac%7B10000%7D%7Bleg%7D%20)
![leg= \frac{10000}{tan(40)}](https://tex.z-dn.net/?f=leg%3D%20%5Cfrac%7B10000%7D%7Btan%2840%29%7D%20)
![leg=11917.54](https://tex.z-dn.net/?f=leg%3D11917.54)
<span>
We can conclude that </span><span>the horizontal (ground distance) from the airport to the airplane's position is
11,917.54 feet.</span>
Answer:
23.8
Step-by-step explanation:
v = 4/3 pi r cube
v =4/3 pi r (15) cube
v=4500 pi
v= 45000 pi /2=4/3pi r cube
1687.5=r cube
r =11.9
d =23.8
(please tell me if its wrong, if it is i will fix it!) :).
