Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
6 + 12 = 18
18/9 = 2
The answer is 2
Hope this helps
<span>The answer to this question is c, two. The top arc of the circle intersects the y=x^2 as each 'limb' extends into infinity. The part of the circle below the x-axis does not intersect the circle. The y=x^2 curve does not dip below the x-axis, but does extend into infinity on both the negative x-axis and positive x-axis.</span>
Answer:
The result of the integral is:
Step-by-step explanation:
We are given the following integral:
Trigonometric substitution:
We have the term in the following format: 
, in which a = 3.
In this case, the substitution is given by:
So
In this question:
So
We have the following trigonometric identity:
So
Replacing into the integral:
Coming back to x:
We have that:
So
Applying the arcsine(inverse sine) function to both sides, we get that:
The result of the integral is:
To find the answer just divide the length of a flower garden by the length of a brick:
11.25 / 0.25 = 45 (that's how many bricks are needed to be put).
There's nothing to round, but you can write it as a decimal to the hundredth place as 45.00.
