Distance traveled = 70 m
Number of rotations = 29

We know, Circumference * Number of rotations = Distance traveled
So, C = 70 / 29
C = 2.41 m

Now, we know, diameter = C / π
So, d = 2.41/3.14 = 0.768

In short, Your Answer would be: 0.8 m

Hope this helps!

Total distance=70m
Revolutions of wheel=29
revolutions ×circumference of wheel=total distance
29×2pi×r=70
2×3.14×r=70/29
Since 2r=d
d×3.14=70/29
d=70×100/29×314
d=0.768
d=0.8m

Make a table of values for the function rule. then graph the function. y=-x²+4

lakkis [162]

Answer:

check the attached picture

Step-by-step explanation:

Given function is $y=-x^2+4$ .

Now we need to make a table of values for the function rule then graph the function.

We are free to plug any values of x like -3,-2,-1,0,1,2,3,... etc becaues domain of polynomial function is all real numbers.

Let's plug x=1 into given function to find the y-value

$y=-x^2+4$

$y=-(1)^2+4$

$y=-1+4$

$y=3$

Hence the first point is (1,3).

Same way we can find few more points to complete the table then graph those points and connect them to get the final graph.
