Consider the expression: (x + y + 3) × (y + 1).
Vladimir79 [104]

Answer:

1 and 2) After multiplying (x+y+3)(y+1) we have

  • xy+x+y^2+4y+3

Which is an equivalent expression after applying the distributive property.

As we can see we have an one of the variables squared,  so we obtain an Parabolic Cillinder

Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second. An olympian ran the 100-meter dash in 9.6 seconds. How mu
EastWind [94]

Given that Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second.

An olympian ran the 100-meter dash in 9.6 seconds.

Then speed of olympian = distance/ time = 100 meter/ 9.6 seconds = 100 meter/ 9.6 seconds = 10.4166666667 meter/ seconds


whis is approx 10.42 meter/seconds

Now we need to find about how much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second.

16.8-10.42 = 6.38 = 6.4

Hence speed of Sarah the cheetah's is approx 6.4 meter per second more than the speed of olympian.
