An ostrich can run 5 mph faster than a giraffe. an ostrich can run 5 mi in the same time that a giraffe can run 4 mi. find the s
bogdanovich [222]
The first thing we must do in this case is to define variables.
 We have then:
 x: speed of the giraffe
 x + 5: speed of the ostrich
 
 By definition we have:
 d = v · t
 d / v = t
 Where,
 d: distance
 v: speed
 t: time
 Since the time is the same then we have:

 5 / (x + 5) = 4 / x
 5x = 4 (x + 5)
 Clearing x we have:
 5x-4x = 20
 x = 20 mph (speed of the giraffe)
 x + 5 = 20 + 5 = 25 mph (speed of the ostrich)
 Answer:
 
20 mph (speed of the giraffe)
 
25 mph (speed of the ostrich)

Find the area of the region bounded by the graphs of y = x, y = −x + 4, and y = 0.
Marrrta [24]
The line y = x and y = -x + 4 intersect when at the point (2, 2).

Expresing y = -x + 4 in terms of x, we have x = 4 - y.

Thus, the area of the region bounded by the <span>graphs of y = x, y = −x + 4, and y = 0 is given by

\int\limits^2_0 {(y-(4-y))} \, dy = \int\limits^2_0 {(y-4+y)} \, dy \\  \\ = \int\limits^2_0 {(2y-4)} \, dy= \left[y^2-4y\right]_0^2 =|(2)^2-4(2)| \\  \\ =|4-8|=|-4|=4

Therefore, the area bounded by the lines is 4 square units.
