Answer:
x = 3
Step-by-step explanation:
It should NOT be "fight of the origin", rather "right of the origin".
Now let's move on to solve the question...
The x-intercept is found by setting the function equal to 0. Thus:
0 = x^3 - 9x
<em>Let's solve this using algebra:</em>

<em />
<em>Hence, x = -3 and x = 3</em>
<em />
The coordinate that is to the right of the origin is the positive one, so x = 3 is the x-intercept we are looking for.

Answer:
Step-by-step explanation:
To write as a decimal.
Decimal defined as the number with a decimal point in it.
also, the decimal point separates part of whole number and the fractional part in the decimal numbers.
To turn this fraction into a decimal number,
all you have to do is to divide the top number by bottom number i.e
Therefore, 7/12 as a decimal is, 0.583333333....
Answer:
3600 gallons of water was removed from the basement.
Step-by-step explanation:
Given:
Rate of each pump = 40 gallons/min
We need to find find the number of gallons of water removed from the basement.
Solution:
Now Given:
After half an hour, the one pump burns out.
Now we know that;
1 hour = 60 mins
hour =
Now for 30 mins both the pumps were working and removing the water.
So we can say that;
Water remove for first 30 mins =
Also Given:
the second pump finishes removing the water half an hour later.
So we can say that;
Water removed for next 30 mins =
Now we can say that;
Total water removed from the basement is equal to sum of Water remove for first 30 mins and Water removed for next 30 mins .
framing in equation form we get;
Total water removed from the basement =
Hence 3600 gallons of water was removed from the basement.
