Donkey Kong and Diddy Kong are keen cyclists. They are doing an 80 km time trial. Donkey sets off at 8 am. He cycles at 30 km/hour until he reaches the halfway point, where there is a steep hill. It takes him 30 minutes to cycle up the hill at 10 km/hour. At the top is the Banana Stand where Donkey stops for 25 minutes for a banana shake. He then continues at 25 km/hr until the end of the time trial. Diddy Kong leaves 45 minutes after Donkey. He cycles at a constant speed of 30 km/hour. At what time does Diddy pass Donkey?

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
