Identify the pattern. then write the next 3 terms in each sequence. 5,10,20,40

answer:

15.59 feet

step-by-step explanation:

we need to find bc and cd

first find bc

we can use the pythagorean theorem

ab^2 + bc^2 = ac^2

11^2 + bc^2 = 13^2

121 + bc^2 =169

subtract 121 from each side

121-121+bc^2 = 169-121

bc^2 = 48

take the square of each side

sqrt(bc^2 ) = sqrt( 48)

bc = 6.92820323

then we need to find cd

we can use the pythagorean theorem

cd^2 + de^2 = ce^2

cd^2 + 5^2 = 10^2

cd^2 + 25 =100

subtract 25 from each side

cd^2 + 25-25 =100-25

cd^2 = 75

take the square of each side

sqrt(cd^2 ) = sqrt( 75)

bc = 8.660254038

bd = bc +cd

      = 6.92820323 + 8.660254038

      15.58845727

$5.500

step-by-step explanation:

$5.50x1000= $5.500

hello from mrbilldoesmath!

answer:

arithmetic

discussion:

first glance at the numbers shows each term is 1 larger than the preceding terms. so we are adding the constant 1 to each term to get the next term. this is an arithmetic progression.
