rounding to nearest 10 to any number follow these rules
1. if number ends 0 , 1 , 2 ,3 4 , 5 take number down to nearset multiple of 10
2. if number ends with above 5 take the upper number multiple of 10
so here
413 + 35.6 + 998.5 + 376 + 85.3
= 410 + 40 + 1000+ 380 + 90
= 1920
The relationship iof the ostrich running at 43 miles per hour is proportional.
<h3>Speed of the ostrich</h3>
Since speed = distance per unit time
The speed of the ostrich is 43 miles per hour. This means that the ostrich covers a distance of 43 miles every hour.
Since the ostrich always covers a distance of 43 miles every hour, we see that distance is proportional to time.
So, the relationship iof the ostrich running at 43 miles per hour is proportional.

Answer:
A polynomial together with the absolute value function can make a pretty good model (see the attachment)
Step-by-step explanation:
With a sufficient number of specified points, a polynomial can make a pretty good model of almost any smooth function. Here, the function's derivative is undefined at a couple of points, so there are some options for those. If the slopes match on either side of those zeros, then the absolute value function can be used to model the "reflection" at the x-axis. Otherwise, a piecewise description can be used.
The left portion of the curve looks a little like a sine wave, but a cubic or other polynomial can model that wave fairly well. The portion to the right of the maximum looks like a bouncing ball, so can be modeled by a piecewise quadratic function.

<em>Comment on the graph</em>
The attached graph is of a 9th-degree polynomial model. Points were added until the model almost matched the curve. If additional points are defined, a higher-degree model may give a better fit. The "bounce" is modeled by the absolute value function.
In the given figure,
line a & b are parallel, line l and m are parallel.
for line a and b are parallel and line l act as a transversal.
So, angle BAC and ACD are the alterantive interior angles.
Angle BAC = Angle ACD
2x = 46
i.e. Angle BAC = 46
Lines l and m are parallel, a line act as a transversal,
So, the angle BAC and angle y are the corresponding angle,
Since the pair of corresponding angles are always equal so,
Angle BAC = y
46 = y
y = 46
Answer : y = 46
