Answer:
a=14, b=58, c=26.5
Step-by-step explanation:
K.E=0.5mv^2
GPE=mgh
The child has both K.E and GPE
g is taken as 9.81
I'm pretty sure it should be the 45. or A
Answer:
#3 2 Right, 4 Down & #4 Vertical Compression
Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches
