Have you ever wondered why runners start at different spots on a track instead of lining up together? This is called a staggered start. Since tracks have semicircles (or half circles) on the ends, if all the runners lined up together, runners in outer lanes would need to run farther than runners in inner lanes. Why? Because the circumference of the outer lane is greater than the circumference of the inner lane. Staggering starting positions ensures that all runners run the same distance! Where do you see circles and semicircles in the world around you? Why could finding the area or circumference be helpful?

Answers

Answer 1

Step-by-step explanation:

A. Where do you see circles and semicircles in the world around you?

1. Ring.

2. Earing

3. Coin

4. Hockey puck

5. Car tyre

6. Dartboard

7. Wreath

8. Plate

9. Hula hoop

10. Mercedes logo

11. Bass drum

12. Drain

B. Why could finding the area or circumference be helpful?

Finding the area or circumference can help us estimate the size of these circular shape/figures, it can tell us the amount of space they can occupy or the amount of materials needed to produce them

What is the compound interest when £1200 is invested for 8 years at a rate of 3.2% compound interest p.a.?

Answers

Answer:

the Compound interest is £1,543.90

Step-by-step explanation:

The computation of the compound interest is shown below:

As we know that

Compound interest is

Amount = Principal × (1 + rate of interest)^number of years

= £1,200 × (1 + 0.032)^8

= £1,200 × 1.286582318

=  £1,543.90

hence, the Compound interest is £1,543.90

We simply applied the above formula so that the correct value could come

Rob is saving money for a down payment on a house. He opens a savings account at his local bank and deposits $1000. He models his savings plan with the equation y=400x+1000
based on his current income and monthly savings rate. What is the meaning of the y-intercept in the equation?

Answers

Answer:

x=-5/2

Step-by-step explanation

y=0

0=400x=1000 divide both sides

x=-5/2

Answer:

The Answer is D: Starting amount in his savings account

Step-by-step explanation:

The y-intercept represents the starting amount in his savings account.

x = 0 for the y-intercept.

y = 400x + 1000

y = 400(0) + 1000

y = 1000

Hi. Please i need help with this . No jokes . I need help with (vii) and (ix)​

Answers

9514 1404 393

Answer:

  (vii)  25/4

  (ix)  -61/6

Step-by-step explanation:

(vii) Once again, we remind you that for ax²+bx+c=0, ...

  α+β = -b/a = -(-7/2) = 7/2 = 3.5

  αβ = c/a = -3/2 = -1.5

Then the desired expression is ...

  α/(β+1) +β/(α+1) = (α² +α +β² +β)/((α+1)(β+1))

  = ((α+β)² -2αβ +(α+β))/(αβ +(α+β) +1)

  = (3.5² -2(-1.5) +3.5)/(-1.5 +3.5 +1) = 18.75/3 = 6.25 = 25/4

__

(ix) α/β +β/α = (α²+β²)/(αβ)

  = ((α+β)² -2αβ)/(αβ) = (3.5² -2(-1.5))/-1.5 = 15.25/-1.5 = -61/6

Answer:

you can create your box plot from the following answers

a) minimum = 13

b) first quartile = 17

c) median = 22.5

d) third quartile = 26.5

e) maximum = 32

e) interquartile range = 26.5 - 17 = 9.5

Step-by-step explanation:

minimum and maximum values are self-explanatory

first quartile is derived by getting the median of the lower half of data (the median will divide the data into the lower half and the upper half)

third quartile is derived by getting the median of the upper half of data

the median is sometimes referred to as the second quartile

box plots are all about quartiles so that you can see where 25% of the data reside, or 50% or 75%, etc

Which is a qualitative graph?

Answers

Step-by-step explanation:

Qualitative graphs are graphs that are used to represent situations that do not necessarily have numerical values. Qualitative graphs represent the essential elements of a situation in a graphical form. For example, Graph A could represent a car that is accelerating at a constant rate.

The numerical information from the definitive quantified variables research is given and represented utilizing quantitative graphs.Qualitative drawings were graphics that are used for circumstances without any numeric value.In graphical form, quality graphs are indeed the primary components of the scenario.Each frequency of attributes and qualities of a data set instance should be known.This analysis allows the researcher or analysts to obtain more massive data sets with the integral feature.

Therefore, the "Second graph" is the qualitative graph.
