Two boats leave the same place at the same time. The first boat heads due north at 10 kilometers per hour. The second boat heads

Maksim231197 [3]

Answer:

18.87 km/hr

Step-by-step explanation:

First boat is heading North with a speed of 10 km/hr.

Second boat is heading West with a speed of 16 km/hr.

Time for which they move = 2.5 hours

To find:

The speed at which the distance is increasing between the two boats.

Solution:

Let the situation be represented by the attached diagram.

Their initial position is represented by point O from where they move towards point A and point B respectively.

$Distance = Speed \times Time$

$Distance\ OA = 10 \times 2.5 = 25\ km$

$Distance\ OB = 16 \times 2.5 = 40\ km$

We can use Pythagorean Theorem to find the distance AB.

AB is the hypotenuse of the right angled $\triangle AOB$ .

According to Pythagorean theorem:

$\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow AB^{2} = OA^{2} + OB^{2}\\\Rightarrow AB^2 = 25^2 + 40^2\\\Rightarrow AB^2 = 2225^2\\\Rightarrow AB^2 \approx 47.17\ km$

The speed at which distance is increasing between the two boats is given as:

$\dfrac{47.17}{2.5} \approx 18.87\ km/hr$

What is the volume of the cone to the nearest cubic meter with radius of 4m and height of 5m

adoni [48]

Answer :

B) 84 m³

Step by step :

$\boxed{ \bold{volume = \frac{1}{3}\pi {r}^{2} h }}$

$volume = \frac{1}{3} \times 3.14 \times 4 \times 4 \times 5 \\ volume = \frac{1}{3} \times 251.2 \\ volume = 83.73 \: {m}^{3} \\ volume = 84 \: {m}^{3}$

What is y > 2x - 4 and 6x +3y < 9

fgiga [73]

you can make a table of values using any intergers and as many as you need in this case I chose 0,1,2 then you replace them in your actual equation and find the values of y.finally plot.

after plotting the points you shade the unwanted region(the sign will direct you) in this case the wanted region is y>.so you shade the less than area.

for the second one you make the equation simpler

6x+3y<9

3y<-6x+9

and also make a table of values,replace were there's x and plot

I hope this helps!
