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:
n exponent 5
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.
♦ The midline's length is the average of the lengths of the top and bottom parallel sides.
Use this equation and substitute values given in each problem, then solve for the missing information.
1. AL = x, CE = 9, OR = 5
2. AL = <em>m</em> - 4, CE = 15, OR = 17
3. OR = y + 5, AL = 15, CE = 18
100 is one of the factors, but there are additional as well..
1 x 200
2 x 100
4 x 50
5 x 4
8 x 25
10 x 20
