Answer:
390 ft²
Step-by-step explanation:
The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 240 ft² What is the area of the larger trapezoid?
We solve the above question using proportion
(Longer base/Area of trapezoid) smaller trapezoid = (Longer base/Area of trapezoid) bigger trapezoid
Let the the Area of the bigger trapezoid = x
Hence,
= 8ft/240ft = 13ft/x ft
Cross Multiply
8ft × x = 240ft × 13ft
x = 240ft² × 12 ft/8 ft
x = 390 ft²
Answer:
Opt. B
Step-by-step explanation:
The key feature is to eval x in a point where |x| is zero, since the vertex of the function is located at that point.
|x|=0 means that y=-4.
Hence the vertex of this point is located at (0,-4)
4 Units down if we compare with the parent function y=|x|
Answer: The speed of rowing is 3.56 miles per hour and speed of current is 1.06 miles per hour.
Step-by-step explanation:
Since we have given that
Let the speed of boat in still water be 'x'.
Let the speed of current be 'y'.
Distance = 1 mile
For Upstream, speed would be
For downstream, speed would be
By graphing method we get that
x = 3.558 miles/hr
and y = 1.058 miles/hr
Hence, the speed of rowing is 3.56 miles per hour and speed of current is 1.06 miles per hour.
