Answer:
4 minutes 3 seconds
Step-by-step explanation:
Step one:
Given data
A kangaroo hops 2 kilometers in 3 minutes
The rate/speed is
rate/speed= 2/3 km per minute
Required
the time taken to cover 3 km
Step two:
We know that
rate= distance/time
2/3= 3/t
cross multiply we have
2t=3*3
2t=9
divide both sides by 2
t= 9/2
t= 4.5 minutes
t= 4 minutes 3 seconds
Answer:
Step-by-step explanation:
The triangle is recognizable as a 30°-60°-90° right triangle, which has side length ratios ...
1 : √3 : 2
Side x is thus twice the length of short side 4, so x = 8.
Side y is √3 times the length of short side x-6 = 2, so y = 2√3.
_____
If you don't happen to recognize the triangle dimensions, you can find x and y using the Pythagorean theorem.
x = √(4² +(4√3)²) = √64 = 8
y = √(4² -2²) = √12 = 2√3
The amplitude and the period of the function are 3 and 2, respectively.
<h3>What are the amplitude and the period of a sinusoidal function?</h3>
Sinusoidal functions are periodic bounded functions whose form is described below:
y = A · sin (2π · t / T + Ф) + y'
Where:
- y' - Midpoint
- A - Amplitude
- t - Time
- Ф - Phase
- T - Period
The period is the horizontal distance between two consecutive peaks or two consecutive bottoms and the amplitude is equal to the half of the distance between a peak and a consecutive bottom. Hence, the amplitude and the period are, respectively:
Amplitude
A = 0.5 · [2 - (- 4)]
A = 3
Period
T = 2 · [0.75 - (- 0.25)]
T = 2
