One diagonal of a kite is twice as long as the other diagonal. if the area of the kite is 400 square meters, what are the lengths of the diagonals?

20m and 40m

Step-by-step explanation:

The area (A) of a kite is calculated using the formula

A = product of diagonals

Let one diagonal be d then the other diagonal is 2d ( twice as long )

Hence

× 2d × d = 400

d² = 400 ← take the square root of both sides

d = = 20

and 2d = 2 × 20 = 40

The diagonals are 20m and 40m in length

$32,660

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
