Dorothy Wagner is currently selling 80 "I ♥ Calculus" T-shirts per day, but sales are dropping at a rate of 2 per day. She is cu
GrogVix [38]

Answer:

Increasing by $66 per day

Step-by-step explanation:

If sales are dropping at a rate of  2 per day, the sales function is:

S = -2t +80

If price is increasing by $1 per day, the daily price function is:

P=1t+7

Revenue is given by daily sales multiplied by daily price:

R = S(t)*P(t) = (-2t+80)*(t+7)\\R(t) = -2t^2+66t+560

The derivate of the revenue function gives us the daily rate of change in revenue:

R(t) = -2t^2+66t+560\\R'(t) = -4t+66

Currently (t=0) her daily revenue is changing by:

R'(0) = -4*0+66\\R'(0) = \$66

Her revenue is increasing by $66 per day.

FWML is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y.
Ganezh [65]

Answer:

x = 5, y = 8, z = -3

Step-by-step explanation:

Opposite sides of a parallelogram are congruent so to find x:

x + 7 = 3x - 3

-2x = -10

x = 5

To find y:

y + 2 = 2y - 6

-y = -8

y = 8

Therefore, z = x - y = 5 - 8 = -3.

Team A faces loses of 5,876 points in Round 1 . How much is the loss of points for each of the 26 players of Team A if the loss
Svetllana [295]

Answer:

226 points were lost per player

Step-by-step explanation:

Since we are evenly spreading the points between all 26 players, we need to solve using division.

Basically, we are dividing the 5876 points among the 26 players.

5876/26 = 226

Therefore, if the points were spread evenly among all 26 players, each player would lose 226 points.
