Answer:

Part 1) The diameter is $D=10.8\ cm$

Part 2) The circumference is $C=33.912\ cm$

Step-by-step explanation:

step 1

Find the diameter

we know that

The diameter is two times the radius

$D=2r$

we have

$r=5.4\ cm$

substitute

$D=2(5.4)=10.8\ cm$

step 2

Find the circumference

The circumference is equal to

$C=\pi D$

we have

$D=10.8\cm\\\pi=3.14$

substitute

$C=3.14(10.8)=33.912\ cm$

(Worth 30 points) What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term

kolbaska11 [484]

Answer:

$a_n=5-2(n-1)$ , all integers where n≥1

Step-by-step explanation:

we know that

The explicit equation for an arithmetic sequence is equal to

$a_n=a_1+d(n-1)$

a_n is the th term

a_1 is the first term

d is the common difference

n is the number of terms

we have

$a_1=5\\a_2=3$

Remember that

In an Arithmetic Sequence the difference between one term and the next is a constant, and this constant is called the common difference.

To find out the common difference subtract the first term from the second term

$d=a_2-a_1=3-5=-2$

substitute the given values in the formula

$a_n=5-2(n-1)$

The domain is all integers for $n\geq 1$

A figure is made of 2 rectangular prisms...<br> what is the volume?

MaRussiya [10]

The volume of the figure that is composed of two rectangular prisms is: 146 cubic in.

<h3>What is the Volume of a Rectangular Prism?</h3>

The volume of a rectangular prism = (length)(width)(height).

The figure can be decomposed into two rectangular prisms. Find the volume of each of the prisms.

Volume of rectangular prism 1:

Length of the prism = 8 in.

Width of the prism = 7 in.

Height of the prism = 1 in.

Volume of rectangular prism 1 = (8)(7)(1) = 56 in.³

Volume of rectangular prism 2:

Length of the prism = 10 in.

Width of the prism = 9 in.

Height of the prism = 1 in.

Volume of rectangular prism 1 = (10)(9)(1) = 90 in.³

Volume of the figure = 90 + 56 = 146 cubic in.

in the early spring the trout at big blue Lake Swim at a deph of 30 feet below sea level when the lake warms up in the summer th

Ludmilka [50]

Answer:

-50 feet

Step-by-step explanation:

The trout is swimming 30 ft below sea level,if it were above sea level it would be positive but since its below it is negative. It then swims 20 feet lower so it would be -50 as a short cut you can use in problems like this one is to ignore the sign's and add it regularly then add the sign after the equation is done.
