Answer:

f(s(w)) = 80w+30

Step-by-step explanation:

Given

The function g(s) = 2s + 30 that represents the number of flowers that bloomed, where s is the number of seeds she planted.

The function s(w) = 40w represents the number of seeds she plants per week, where w represents the number of weeks.

Required

Composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks.

The composite expression needed is g(s(w)

g(s(w)) = f(40w)

To get g(40w), we will replace s with 40w in g(s) as shown;

g(s) = 2s+30

g(40w) = 2(40w)+30

g(40w) = 80w+30

g(s(w)) = 80w+30

Hence the required composite function is expressed as g(s(w)) = 80w+30

Answer:

f(s(w)) = 80w+30

Step-by-step explanation:

Just wanted to confirm, the person who answered your question prior to mine is correct. I just took the exam on polynomial operations and graded, this was what I had written, and it is correct. W represents the weeks in f[s(w)], where its added to 80. s(w) tells the number of seeds per each week.

The line ab has midpoint (-2, 4) a has coordinates (3, -2) find the coordinates of b
damaskus [11]

Answer:

b = (- 7, 10 )

Step-by-step explanation:

Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ \frac{1}{2} (x₁ + x₂ ), \frac{1}{2} (y₁ + y₂ ) ]

let the coordinates of b = (x, y ) then use the formula and equate to the coordinates of the midpoint, that is

\frac{1}{2} (x + 3) = - 2 ( multiply both sides by 2 )

x + 3 = - 4 ( subtract 3 from both sides )

x = - 7

\frac{1}{2} (y - 2) = 4 ( multiply both sides by 2 )

y - 2 = 8 ( add 2 to both sides )

y = 10

Thus the coordinates of b are (- 7, 10 )

8. Bob bought a pair of tennis shoes on sale
mr_godi [17]

Answer:

20%

Step-by-step explanation:

So, I would set this up as a proportion-

72          x

90        100

Cross multiply-

100 x 72 = 7200

Divide-

7200/90 = 80

Subtract-

100 - 80 = 20

So, it is a 20% decrease
