See attached for a sketch of some of the cross sections.
Each cross section has area equal to the square of the side length, which in turn is the vertical distance between the curve y = √(x + 1) and the x-axis (i.e. the distance between them that is parallel to the y-axis). This distance will be √(x + 1).
If the thickness of each cross section is ∆x, then the volume of each cross section is
∆V = (√(x + 1))² ∆x = (x + 1) ∆x
As we let ∆x approach 0 and take infinitely many such cross sections, the total volume of the solid is given by the definite integral,
The answer is 2.
it’s adding 2 everytime!
Answer:
<em>An exponential function is a Mathematical function in form f (x) = ax</em><em>.</em>
<em>
</em>
Step-by-step explanation:
<em> where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.</em>
<em>NoTe</em><em>:</em><em> The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.</em>

You may go the super easy way and choose 1 as the whole number and 0.28 as the decimal number. Then you'd obviously have 
Otherwise, to be a bit more creative, you can observe that
And since 1/25=0.04, you can also choose 7 as the integer, and 0.04 as the decimal to get
Answer:
n= 3
Step-by-step explanation:
3 (4 + n) = n + 18
you take 3x4=12
then 3x3=9 then you add 12 and 9 which would be in the ( )
12+9 = 21
then if you replace n =3 on other side and add it to 18 answer is 21
therefore both sides would equal 21 so n=3
3(4+3)=3+18
21=21
