Answer:

A 27

Step-by-step explanation:

f(5) means x = 5, so substitute 5 into 1/9(3)^x

f(5) = 1/9(3^5) = 1/9(243) = 27

EleoNora [17]

Answer:

see below

Step-by-step explanation:

given;

Planet Earth has an approximate diameter of 1.2742 x 10¹⁰ millimeters.

The sun has a diameter of 1.391 x 10⁶ kilometers.

find:

Part I:

Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters?

Part II:

Approximate how many times greater the sun's diameter is than planet Earth's.

-------------------------------------------------------------------------------------------------------

part I:

the best measurement to represent the lengths of the sun and Earth's diameters is kilometers.

= planet dia. = 1.2742 x 10¹⁰ mm x <u> 1 km </u> = 12,742 km

1,000,000 mm

= sun dia. = 1.391 x 10⁶ km = 1,391 x 10³ km = 1,391,000 km

part II:

the approximate scale dia ratio of earth to sun is = sun dia. over earth's dia.

= <u>1,391,000 km</u>

12,742 km

= 109.17 times

therefore,

109.17 times greater the sun's diameter is than planet Earth's.

Use the Venn Diagram in #1 to answer the following question: How many elements are contained in B ∪ C ?

Ilya [14]

<h3>Answer: D) 63</h3>

======================================================

Work Shown:

The notation B U C means "set B or set C". The U refers to set union. A set union is where you combine two sets and toss out any duplicates. In terms of a venn diagram, we will add up any number that is either in set B, set C, or both sets at the same time.

So we just add up the numbers: {6, 19, 5, 8, 3, 22} to get

6+19+5+8+3+22 = 63

There are 63 items in either set B, set C or both.

-----------------

Alternative route:

n(B) = number of items in set B

n(B) = 6+19+5+8 ... add up the numbers in circle B

n(B) = 38

n(C) = number of items in set C

n(C) = 3+5+8+22

n(C) = 38

n(B and C) = number of items in both set B and set C

n(B and C) = 5+8

n(B and C) = 13

n(B U C) = n(B) + n(C) - n(B and C)

n(B U C) = 38 + 38 - 13

n(B U C) = 63
