Answer:

Normal speed = 711.11 km/h (Approx)

Step-by-step explanation:

Assume;

Normal speed = x

New speed = x - 25% of x = 0.75 x

Time taken = t

New time taken = t + 1.5 hour

Total distance

Computation:

Total distance = 3,200 km

Speed = Distance/Time

x = 3200 / t

t = 3200/x

so,

0.75 x = 3200 / (t+1.5)

0.75 x = 3200 / (3200/x+1.5)

0.75 x = 3200 / [(3200 + 1,5x)x]

x = 711.11 km/h

Normal speed = 711.11 km/h (Approx)

​Aki's Bicycle Designs has determined that when x hundred bicycles are​ built, the average cost per bicycle is given by​ C(x)=0.
Semmy [17]

Answer:

<u>maximum of 2 bicycle</u>

Step-by-step explanation:

Given the average cost per bicycle modeled by the equation

C(x) = 0.5x^2-1.5x+4.83

C(x) is in hundreds of dollars

x is number of bicycle

The number of bicycle that will minimize the cost occurs when dC/dx = 0

dC/dx = 2(0.5)x - 1.5

dC/dx = x - 1.5

Since dC/dx = 0

0 = x - 1.5

x = 0+1.5x = 1.5

Hence the shop should  buy <u>maximum of 2 bicycle</u> to minimize the cost

A graphic artist receives a royalty payment of 5% for each game sold, and has an agent who gets 3% of what the graphic artist ge
Bumek [7]
The graphic artist receives 5% amount of the total sales as his royalty payment. The 3% from this royalty payment goes to his agent and remaining 97% are with the artist. So first we calculate the initial 5% amount the graphic artist will recieve, which will be:

0.05(2,000,000)= 100,000

$100,000 is the total royalty payment the graphic artist will receive. From this amount 3% goes to agent and 97% goes with artist. So the actual amount graphic artist will earn will be:

0.97(100,000) = 97,000

Thus, the graphic artist earns $97,000
