Find the surface area of a sphere with a radius of 2√2 feet.94.5 square feet
100.5 square feet
25.1 square feet
35.5 square feet

Answers

Answer 1

Answer:

Answer: 100.5 square feet

Step-by-step explanation:

To find : surface area of sphere with radius of $2√(2)feet$

The formula used to calculate surface area of sphere is = $4* \pi* r^2$

where r is the radius of sphere.

Putting the values we get:

surface area of sphere = $4* 3.14* (2√(2)feet)^2=100.5square feet$

Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet

In an inverse variation, what happens to the values of the two variables?a.
they are both constant
c.
as one value increases, the other increases
b.
they both decrease
d.
as one value increases, the other decreases

Answers

d.
as one value increases, the other decreases
This is because when both values are multiplied, you get a constant so if one is increased the other needs to be reduced so their product can meet up with the constant

Which is equivalent to 243 ^2/5

a. 3
b.6
c.9
d.1w

Answers

Answer:

The correct option is c.

Step-by-step explanation:

The given expression is

$243^{(2)/(5)}$

According to the exponential property:

$x^(mn)=(x^(m))^n$

Using this rule we get

$243^{(2)/(5)}=(243^{(1)/(5)})^2$

$243^{(2)/(5)}=(3)^2$ $(243^{(1)/(5)}=3)$

$243^{(2)/(5)}=9$

The value of given expression is 9. Therefore the correct option is c.

I hope this helps you

an exponential function is expressed in the form y=a*b/\x. the relation represents a growth when ________ and a decay when ________.

Answers

That function grows when 'b' is more than 1 and 'x' is positive, or when b <1 and x<0. It decays when b> 1 and x <0, or when b<1 and x> 0.

Answer 1: b>1

Answer 2: 0b<b<1

An exponential function is expressed in the form y=axb^x. The relation represents a growth when "b>1" and a decay when "0<b<1".
