A runner covers the last straight stretch of a race in 4 s. During that time, he speeds up from 5 m/s to 9 m/s. What is the runner’s acceleration in this part of the race?
Answers
Given,
Time taken to cover the last last straight stretch of a race = 4 seconds
He speeds up from 5 m/s to 9 m/s
To find,
The acceleration of the runner.
Solution,
We can simply solve this numerical problem by using the following process.
Here,
Initial velocity (u) = 5 m/s
Final velocity (v) = 9 m/s
Time (t) = 4 seconds
Acceleration (a) = ?
According to the formula of kinematics,
a = (v-u)/t
a = (9-5)/4 [By putting the given values.]
a = 4/4 = 1 m/s²
(We have used SI unit of the acceleration, because all the initial physical quantities are also in SI units.)
Hence, the acceleration is 1 m/s²

find the area of the figure
thank you <3 will give brainliest
Answers
Answer:
13.5
Step-by-step explanation:
A triangles area is base x height divided by two.
Height is 3, and base is 9.
9 x 3 = 27 / 2 = 13.5
a = base x height / 2
but only for a right triangle meaning one of the angles of the triangle has to be 90 degrees. So we split the triangle in half and then solve for the area of the two triangles and add them together.
area of triangle 1 = 3 x 6 / 2 or 9
area of triangle 2 = 3 x 3 / 2 or 4.5
Total area is 13.5

Two points on a circle are points A(-11,7) and B(-9,-3)
1. Determine the equation of a lone containing the center of the circle
2. If the x-coordinate of the center is -5, determine the circle's center: (-5,?)
Answers
Answer:
( x + 5 )² + ( y - 3 )² = 52
Step-by-step explanation:
Let find the equation of the line going through A( - 11, 7 ) and B( - 9, - 3 )
m = [tex]\frac{-3-7}{-9+11}[/tex] = - 5
y - 7 = - 5( x + 11 )
y = - 5x - 48
Now, let find the equation of the line passing through midpoint of the segment AB
Coordinates of that midpoint is ( [tex]\frac{-11-9}{2}[/tex] , [tex]\frac{7-3}{2}[/tex] ) = ( - 10 , 2 )
Slope of the perpendicular line is [tex]\frac{1}{5}[/tex] ( opposite reciprocal of ( - 5 )
y - 2 = [tex]\frac{1}{5}[/tex] ( x + 10 )
y = [tex]\frac{1}{5}[/tex] x + 4 ........... (1)
Coordinates of an intersection of two lines (1) and x = - 5 are coordinates of the center of the circle
y = [tex]\frac{1}{5}[/tex] ( - 5 ) + 4 = 3 ⇒ y = 3
O( - 5 , 3 ) is the center
The last!! RADIUS which is OA or OB
r = [tex]\sqrt{(-5+11)^2 +(3-7)^2}[/tex] = √52
( x + 5 )² + ( y - 3 )² = 52

Answers
Answer:
y = 2x +5
Step-by-step explanation:
f(x) = y means that you want y to be on one side of the equation by itself.
so you need to isolate y.
2y - 4x = 10
first add 4x to both sides of the equation
2y = 4x + 10
then, divide by 2 on both sides to have y by itself
y = 4/2x + 10/2
finally, simplify:
y = 2x + 5
Do employer-sponsored wellness programs work? About 5000 employees at the University of Illinois at Urbana-Champaign volunteered for a study to find out. Researchers randomly assigned 3300 volunteers to a treatment group and the remaining 1534 to a control group. Employees in the treatment group were invited to take paid time off to participate in a wellness program. Those in the control group were not allowed to participate. One measure of the program's effectiveness was employee attrition. In the 2-year period following the start of the study, 356 of the people in the treatment group left their job for any reason, compared to 184 of the people in the control group. Do these results provide convincing evidence at the a= 0. 05 level that offering employees paid time off to participate in a wellness program reduces the proportion who leave their job within 2 years for people similar to the ones in this study?
Answers
The research analysis computed do not give supporting evidence that employer-sponsored wellness programs work.
How to analyze the research study?From the information given, the sample proportion for treatment group will be:
= 356/3300 = 0.1078
The sample proportion for the control group will be:
= 184/1534 = 0.1199
The z value is -1.24 and the p value is given as 0.1078. In this case, we fail to reject the null hypothesis.
Therefore, the results do not provide convincing evidence that offering employees paid time off to participate on a wellness program will reduce the proportion of those who leave their job within two years.
