a vendor has 30 umbrellas to sell. he sells them for $20 each. the function m(u) = 20u models the total amount of money the vendor makes from selling u umbrellas. what are the practical domain and range of the function?

Domain={0,30},Range={0,600}

Step-by-step explanation:

Total umbrellas=30

Price of each umbrella=$20

m(u)=20u

where

u is number of umbrellas

m(u) total amount vendor makes by selling u number of umbrellas

So Practically,The extreme cases are

So Domain is {0,total number of umbrellas}={0,30}

Putting this extreme value of domains as u in function m(u),

we get the range of m(u)={0$20,30$20}

⇒ Range={0,$600}

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
