Answer:

112 cm^2

Step-by-step explanation:

Area of a rhombus is equal to half of the product of the diagonals, so it is 14 * 2 * 8 / 2 = 14cm * 8cm = 112 cm^2.

Other point of view: It is the sum of areas of two triangles of area 14*8/2. So the area is 14*8.

A car rental company charges a one-time application fee of 40 dollars, 55 dollars per day, and 13 cents per mile for its cars. A
liberstina [14]

Answer:

A) C(d,m) = 40 + 55d + 0.13m

B) $448

Step-by-step explanation:

Let 'd' be the number of days and 'm' the number of miles driven.

A) The cost function that describes a fixed amount of $40, added to a variable amount of $55 per day (55d) and a variable amount of 13 cents per mile (0.13m) is:

C(d,m) = 40 +55d +0.13m

B) If  d = 5 and m =600, the total cost is:

C(5,600) = 40 +55*6 +0.13*600\\C(5,600)=\$448

The cost is $448.
