Let the points be A,B,C

  • A(0,0)
  • B(24,16)
  • C(8,20)

#A

\\ \bull\sf\leadsto AB=\sqrt{(24-0)^2+(16-0)^2}=\sqrt{24^2-16^2}=\sqrt{576-256}=\sqrt{320}=17.4units(leg3)

\\ \bull\sf\leadsto AC=\sqrt{(8-0)^2+(20-0)^2}=\sqrt{8^2+20^2}=\sqrt{64+400}=\sqrt{464}=21.4units(leg1)

\\ \bull\sf\leadsto BC=\sqrt{(24-8)^2+(26-20)^2}=\sqrt{16^2+(-4)^2}=\sqrt{256+16}=\sqrt{272}=16.4units(leg2)

#B

We have to find perimeter

\\ \bull\sf\leadsto Perimeter=AB+AC+BC

\\ \bull\sf\leadsto Periemter=17.4+16.4+21.4

\\ \bull\sf\leadsto Perimeter=55.2units

#C

The length of leg3=17.4units

Answer:

Solution given;

points be A,B,C

P(0,0)

Q(24,16)

R(8,20)

a. Calculate the length of each leg of the race?

each leg's length

By using distance formula we can find length

I.e. d=\sqrt{(x_2- x_1)²+(y_2-y1)²}

<u>leg 1</u>

PR

=\sqrt{(8-0)²+(20-0)²}=\sqrt{464}=4\sqrt{29}

<u>=21.54</u><u> </u><u>km</u>

<u>leg 2</u>

QR

\sqrt{(8-24)²+(20-16)²}=\sqrt{272}=4\sqrt{17}

=<u>16.49 </u><u>km</u>

<u>leg 3</u>

PQ

=\sqrt{(24-0)²+(16-0)²}=\sqrt{832}=8\sqrt{13}

=<u>28.84 </u><u>km</u>

b. Calculate the total racing distance?

<u>The total racing distance</u>=Sum of all side

=PR+QR+PR

=21.54+16.49+28.84

=<u>66.87 </u><u>km</u>

c. If an observer’s boat is located at the midpoint of the second leg of the race, calculate the distance between this boat and the finishing point?

Solution given:

<u>distance between this boat and the finishing point</u>=\frac{leg\:2}{2}=\frac{16.49}{2}=8.25units

=<u>8.25 </u><u>k</u><u>m</u>

How do you solve for a and b?
natali 33 [55]
You need to isolate b on one side of the equation then divide both side by h finally move b on the other side of the equation by subtracting it from both sides of the equation and then you have what b equals to

The number of compact discs N purchased each year, in millions, can be
Aleonysh [2.5K]

Answer:

126.5 years

Step-by-step explanation:

N(t) = 384(1.13)^t

2,000,000,000 = 384(1.13)^t

(1.13)^t = 2,000,000,000/384

log [(1.13)^t) = log (2,000,000,000/384)

t × log 1.13 = log (2,000,000,000/384)

t = [log (2,000,000,000/384)]/(log 1.13)

t = 126.5
