Answer: a) Our camera is 1.2 times faster than friend's camera.
b) We can take 20 pictures while the rider is in the air.
Step-by-step explanation:
According to the given problem
a) 1 picture in our camera takes time =0.125 seconds
1 picture in friend's camera takes time =0.15 seconds
The rate of pictures taken by our camera=
The rate of pictures taken by friend's camera=
Now, scale factor by which our camera is faster then friend's camera=
Thus Our camera is 1.2 times faster than friend's camera.
b) Number of pictures we can take while the rider is in the air [∵Duration of motocross rider is in the air = 2.5 seconds.]
Thus we can take 20 pictures while the rider is in the air.
Answer:
the base of the ladder is 27.89 ft away from the building
Step-by-step explanation:
Notice that this situation can be represented with a right angle triangle. The right angle being that made between the ground and the building, the ladder (32 ft long) being the hypotenuse of the triangle, the acute angle of being adjacent to the unknown side we are asked about (x). So, we can use the cosine function to solve this:
which rounded to the nearest hundredth gives;
x = 27.89 ft
