A sphere has a diameter of 0.926 inch.
frosja888 [35]

Answer:

The volume of the sphere is V=0.416 \:in^3.

Step-by-step explanation:

The volume enclosed by a sphere is given by the formula

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

Where r is the radius of the sphere.

The diameter of a sphere is twice as long as any radius of the same sphere and is given by the formula

                                                   d=2r

We know that the diameter of the sphere is 0.926 inch. The radius is

\frac{0.926}{2}=0.463

The volume of the sphere is

V=\frac{4}{3}(3.14)(0.463)^3 \approx0.4155385

and rounding to the nearest thousandth we get V=0.416 \:in^3.

Use the graph that shows the solution to f(x)=g(x) .
n200080 [17]

Answer:

1.  x=3   x=1

2.  x=0

Step-by-step explanation:

We want f(x) to equal g(x)

f(x)=g(x)

1/(x-2) = (x-2)

Using cross products

1 = (x-2) * (x-2)

1 = x^2 -2x-2x+4

Subtract 1 from each side

1-1 = ^2 -2x-2x+4-1

0 = x^2 -4x+3

Factoring

What number multiplies to 3 and adds to -4

-3*-1 = 3

-3+-1 = -4

0= (x-3) (x-1)

Using the zero product property

x-3 =0     x-1=0

x=3   x=1



2.  f(x)=x^2+4x+2

g(x)=(1/2)^ x+1


From the graph,we can see they intersect at x=0

Steven has $150. John has J dollars. Steven has 30 less than 2 times the amount John has. How much does John have?
Sedaia [141]

Answer:

J = 90

John has 90 dollars.

Step-by-step explanation:

We need to find how much money John has. To find how much J equals we need to break it down.

We already know that Steven has 150 dollars. We also know that he has 30 less than two times the amount John has.

Steven has 30 less than two times the amount John has.

So 150 + 30 = 180

180 is two times the amount John has.

Because 180 is two times the amount John has we need to divide by two.

180 ÷ 2 = 90.

J = 90. Therefore John has 90 dollars.

This question was tricky! I hope I helped a little! Have a great day!!
