Answer:

O 81 km per hour

Explanation

Given parameters:

Number of days traveled = 3 days

Distance covered on the first day = 1080km

Time of travel = 10hrs

Rate of travel = 108km/hr

Time of travel on second day = 12hrs

Rate of travel = 90km/hr

Time of travel on third day = 18hrs

Rate of travel = 60km/hr

Unknown

Average speed = ?

To find the average speed, we sum the distances and divide by the sum of the time.

Average speed = $\frac{Total distance}{total time}$

we do not know the second and third distances;

Distance = speed x time

D2 = 90 x 12 = 1080km

D3 = 60 x 18 = 1080km

Now;

Average speed = $\frac{1080 + 1080 + 1080 }{10 + 12 + 18 }$

Average speed = $\frac{3240}{40}$ = 81km/hr

The average speed is 81km/hr

Find the domain and range of the function: f(t)=sec[((pi)t)/4]

beks73 [17]

The domain and range of the function f(t)=sec[((pi)t)/4] are the following:

Domain: All the real numbers except t = 2 + 4k, where k is an integer.

Range: (-∞, -1] U [1, ∞)

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

Sidana [21]

Answer:

$\frac{31}{20}\pi$

Step-by-step explanation:

The circumference of circle G is 2pi, which means that HJ is equal to 81/360*2pi = 9pi/20, which means that RJ is equal to 18pi/20-9pi/20 = 9pi/20. Therefore, RHJ is equal to the circumference of the area minus RJ, which is equal to 40pi/20 - 9pi/20 = 31pi/20

I hope this helps
