Answer is C. Set of first part of the binary set is domain and second part of it is range. So the domain will be {5, 7, 11, 4, –2} and the range will be {3, 1, –2, 9, 4}

The mass of the sun is 2.13525×10^30 kilograms. The mass of Mercury is 3.285×10^23 kilograms.

Rama09 [41]

Answer:

The mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Step-by-step explanation:

We are given that

Mass of the sun= $M=2.13525\times 10^{30}$ kg

Mass of Mercury, $m=3.285\times 10^{23}$ kg

We have to find how many times greater is the mass of the sun than the mass of Mercury.

Mass of sun/Mass of mercury= $\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}$

Mass of sun/Mass of mercury $=0.65\times 10^{30-23}$

Using the property

$a^x/a^y=a^{x-y}$

Mass of sun/Mass of mercury $=0.65\times 10^{7}$

Mass of sun/Mass of mercury $=65\times 10^5$

Mass of Sun= $65\times 10^5$ times Mass of Mercury

Hence, the mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Plz help asap i really need it for 30 points

Pani-rosa [81]

Answer:

13.04 cm^2

Step-by-step explanation:

Larger Circle diameter is 12.5 cm and the smaller is 3.5 cm

The Area of a circle is A = πr^2 = πd^2/4

Larger Circle divide the diameter by 2 = 6.25 cm

Smaller Circle dive the diameter by 2 = 1.75 cm

Using above formula A = 122.71846303085 cm^2 &

Finally we deduct the smaller Area from the larger Area

A = 9.6211275016187 cm^2 - 9.6211275016187 cm^2

122.71846303085 cm^2 - 9.6211275016187 cm^2 =

113.0973355292 cm^2 thus 13.04 is your answer since I used the

π = 3.1415926535898

A = area

π = pi = 3.1415926535898
