Graph the function f(x)=1/2 sqrt(x+1)
goldenfox [79]

The function is defined only if x+1 \geq 0 \iff x \geq -1. So, the leftmost point is x=-1, and we have


f(-1)=\frac{1}{2}sqrt(-1+1) = 0


So, the first point is (-1,0)


The three additional points seem arbitrary, so let's choose x=0,1,2. We have:


f(0)=\frac{1}{2}sqrt(0+1) = \frac{1}{2}


So, the second point is (0,\frac{1}{2})


f(1)=\frac{1}{2}sqrt(1+1) = \frac{\sqrt{2}}{2}


So, the third point is (1,\frac{\sqrt{2}}{2})


f(2)=\frac{1}{2}sqrt(2+1) = \frac{\sqrt{3}}{2}


So, the fourth point is (2,\frac{\sqrt{3}}{2})

What is the value of x?​
Kazeer [188]

Answer:

Step-by-step explanation:

The volume of a sphere is

V=\frac{4}{3}\pi r^3

We are told our volume is 500pi/3, so we fill that in and solve for r:

\frac{500\pi}{3}=\frac{4}{3}\pi r^3

Start by multiplying both sides by 3 over 4 pi:

(\frac{3}{4\pi})\frac{500\pi}{3}=(\frac{3}{4\pi})\frac{4\pi}{3}r^3

Simplifying gives us

125=r^3

Take the cubed root of both sides to get that

r = 5

The amounts of household waste generated in a region during two years were 23,400,000 tons and 48,100,000 tons. What was the tot
trasher [3.6K]

The first step to do is to calculate first the total household waste generate for the two years. That is:

total waste generated = 23,400,000 tons + 48,100,000 tons

total waste generated = 71,500,000 tons

 

Now, to write either a very big number or a very small number in a form of scientific notation simply means to write it in a decimal form such as: 12.5 * 10^10

 

Now to write 71,500,000 in scientific notation, the decimal form is 7.15, however we still need to find out the * 10^n factor. The value of n depends on the number of places the decimal point was moved. If the movement was from right to left, the value of n is positive and if the movement was from right to left, the value of n is negative. Since the decimal point was moved by 7 places, hence the complete scientific notation is:

 

7.15 * 10^7 tons
