Lucy did 8 laps of an 800m derek did 12 laps of a 1.5km track on his bike who went further and by how munch

Answers

Answer:

Derek; by 11600 m.

Step-by-step explanation:

Convert 1.5km into m.

1.5 is 1500m.

1500 * 12 = 18000 m

8 * 800 <= Lucy

6400 m  <= Lucy's distance

18000-6400=11600m

Based on the information, Derek went further by 11600m.

Lucy did 8 laps of an 800m. The total distance will be:

= 8 × 800m

= 6400m

Derek did 12 laps of a 1.5km track. The total distance will be:

= 12 × 1500m

= 18000m

Therefore, the difference will be:

= 18000m - 6400m

= 11600m

PLEASE HELPP! The diameter of a decorated plate is 20 centimeters. There is a flower painted every 15.7 centimeters around the edge of the plate. How many flowers are painted on the plate? Use 3.14 for

Answers

Answer:

4 flowers

Step-by-step explanation:

First we need to calculate the circumference of the plate.

C = πd

Given

diameter d = 20cm

C = 3.14(20)

C = 62.8 cm

If there is a flower painted every 15.7 centimeters around the edge of the plate, the amount of flower on the plate will be;

Number of flower = Circumference of the plate/length of flower

Amount of flower = 62.8/15.7

Amount of flower = 4

Hence there are 4 flowers painted on the plate

4

A new cars salesperson, sold an average of $28,000 per day for the first 5 days she worked.
The next 3 days she worked, she sold an average of $42,000. How much did she sell on average
per day over the entire 8 days?

Answers

Answer: 15

Step-by-step explanation:

The average number of cars sold for entire 8 days is $33250.

What is the average?

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, a new cars salesperson, sold an average of $28,000 per day for the first 5 days she worked.

So, number of cars sold for 5 days =28,000×5

= 140000

The next 3 days she worked, she sold an average of $42,000.

Number of cars sold for 3 days

= 42,000×3

= 126000

So, average of 8 days =(140000+126000)/8

= 266000/8

= 33250

Therefore, the average number of cars sold for entire 8 days is $33250.

How do I find the 5 roots of 1^(1/5) using De Moivre's Theorem?​

Answers

Do you mean the 5th roots of 1? Or the 5th roots of 1^(1/5), i.e. the 5th roots of the 5th roots of 1?

I assume you mean the former. To begin with,

1 = exp(0°i ) = cos(0°) + i sin(0°)

Take the 5th root, i.e. (1/5)th power of both sides, so that by DeMoivre's theorem,

1^(1/5) = [ cos(0°) + i sin(0°) ]^(1/5)

1^(1/5) = cos((0° + 360°n)/5) + i sin((0° + 360°n)/5)

where n = 0, 1, 2, 3, or 4. Then 1^(1/5) has the 5 possible values,

• cos(0°/5) + i sin(0°/5) = 1

• cos(360°/5) + i sin(360°/5) = cos(72°) + i sin(72°)

• cos(720°/5) + i sin(720°/5) = cos(144°) + i sin(144°)

• cos(1080°/5) + i sin(1080°/5) = cos(216°) + i sin(216°)

• cos(1440°/5) + i sin(1440°/5) = cos(288°) + i sin(288°)

If you wish, or are required to, you can go on to write these in terms of radicals by expanding cos(5x) and sin(5x) (where x = 72° so that 5x = 360°). For example,

cos(5x) = cos⁵(x) - 10 cos³(x) sin²(x) + 5 cos(x) sin⁴(x)

cos(5x) = cos⁵(x) - 10 cos³(x) (1 - cos²(x)) + 5 cos(x) (1 - cos²(x))²

cos(5x) = 16 cos⁵(x) - 20 cos³(x) + 5 cos(x)

which follows from the expansion

(cos(x) + i sin(x))⁵ = cos(5x) + i sin(5x)

due to DeMoivre's theorem and equating the real parts. Then cos(5x) = 1, and you can try to solve for cos(x) :

1 = 16 cos⁵(x) - 20 cos³(x) + 5 cos(x)

Actually, it would be easier to find sin(x) first, since sin(5x) = 0. The expansion in terms of sin(x) will look quite similar to the one shown here.
