All the students can fit into the 60 second video and there will be 15 seconds left. 5 times 9 = 45. So, all of the students will equal a video of 45 seconds. To figure out the time left, you subtract, 60-45, which equals 15 extra seconds.
Answer:
Since it's a right angled triangle,
taking 61 as reference angle,
cos61 = b/h
or, cos61 = b/8
or, b = cos61.8
so, b = 3.9 feet
The bottom of the ladder is 3.9 feet away from the side of the house.
Answer:
Option D.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
f(t) = a*sin (b*t +c) + d
Please, see attached picture below.
By looking at the picture with all the possible cases, we can tell that the correct option is D.
The function has a period of T = 6π
Max . Amplitude = 9
Min . Amplitude = -5
Answer:
D = 110
Step-by-step explanation:
Given,
In a parallelogram ABCD,
∠A =70∘
∠A + ∠B = 180∘.. (supplementary angles)
∠B = 180∘ – 70∘ = 110∘
∠A = ∠C and ∠B = ∠D.. (Opposite angles of parallelogram)
∠A = 70∘, ∠B = 110∘, ∠C = 70∘, ∠D = 110
