Answer:
Uniform motion always travel in equal distances in equal intervals of time. So the graph will always be constant.
Once you draw the diagram of a uniform motion, when it comes to plotting points you can easily identify if the points go in a constant rate(uniform) or in uneven distances(non-uniform).
Answer:
r = 6.40 feet
Step-by-step explanation:
Given line AB is tangent to circle O at point A, this means ∡OAB = 90°
Hence this is a right angle triangle and we can use the Pythagorean theorem.
r² + 20² = 21²
r² = 21² - 20²
r² = 441 - 400
r² = 41
r = √41 = 6.40 feet
Answer:
E (Y) = 3
Step-by-step explanation:
If a 4-sided die is being rolled repeatedly; and the odd-numbered rolls (1st 3rd,5th, etc.)
The probability of odd number roll will be, p(T) =
However, on your even-numbered rolls, you are victorious if you get a 3 or 4. Also, the probability of even number roll, p(U) =
In order to calculate: E (Y); We can say Y to be the number of times you roll.
We know that;
E (Y) = E ( Y|T ) p(T) + E ( Y|U ) p(U)
Let us calculate E ( Y|T ) and E ( Y|U )
Y|T ≅ geometric =
Y|U ≅ geometric =
also; x ≅ geometric (p)
∴ E (x) =
⇒ = 4 ; also = 2
E (Y) = 4 × + 2 ×
= 2+1
E (Y) = 3
Answer:
Step-by-step explanation:
We are given the following information in the question:
where, R is the tip speed, T is the speed tip of blade and W is the speed of wind.
We have to find , whem W = 75 km per hour, , T = 150 km per hour
Formula:
Putting all the value, we have:
