Answer:
<h2><em>
50.42m/s</em></h2>
Step-by-step explanation:
Average speed is the change in distance of a body with respect to time. This is expressed as:

Given the function of the height in metres expressed as y = 56t − 1.86t² and time interval [1,2]
t₁ = 1sec and t₂ = 2 secs
y(t₂) = 56t₂ − 1.86t₂²
y(2) = 56(2) − 1.86(2)²
y(2) = 112-7.44
y(2) = 104.56
y(t₁ ) = 56t₁ − 1.86t₁ ²
y(1) = 56(1) − 1.86(1)²
y(1) = 56-1.86
y(1) = 54.14
Substituting the derived value into the formula for finding the average speed:

<em>Hence, the average speed over the given time intervals. [1, 2] is 50.42m/s</em>
Answer:
P(1,2) m = 3 Since you are given a point and a slope, use the point-slope form for the equation of a line: y - y1 = m(x - x1)
y - 2 = 3(x - 1)
y - 2 = 3x - 3
y = 3x - 1 hope this helps

Answer:
0.36
Step-by-step explanation:
Given, a circle with radius, 
Area of circle =
Substitute 
Area of whole circle
Square is inscribed in it whose each side is 
Area of square 
We can see that area of the white circle
= area of the whole circle - area of square

Probability of falling a random point within the white circle


Rounding to nearest hundredth.
Probability of falling a random point within the white circle would be 0.36
