Step-by-step explanation:
We have, Sorin hits a cricket ball straight up into the air. After 1.5 s, the ball is falling straight down with a speed of 6.5 m/s.
We want to find the initial vertical velocity of the ball.
The relation between initial speed, final speed, acceleration and time is given by using first equation of kinematics. Let v₀ is the initial speed. So,
Here, v = -6.5 m/s, t = 1.5 s and a = -g
So, the initial velocity of the ball is 8.2 m/s and the formula used is (1).
Answer: The total registered voters of the city Raleigh i.e. 9500 registered voters.
Step-by-step explanation:
In statistics , the term population refers to the entire group of individuals having similar characteristics .
The the population of this survey is the total registered voters of the city Raleigh i.e. 9500 registered voters., because a telephone poll have selected a sample regarding of the registered voters and a sample is a finite subset of a population.
Therefore, the population of this survey is the total registered voters of the city Raleigh.
Since, The city of Raleigh has 9500 registered voters.
Thus, population of this survey is 9500 registered voters.
The difference of four times a number and 5 is 39 can be expressed algebraically as:
4x - 5 = 39
Now, we can solve for x.
Add 5 to both sides:
4x - 5 + 5 = 39 + 5
4x = 44
Divide both sides by 4 to solve for x:
4x/4 = 44/4
x = 11
