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

A group of students formed a circle during a game. The circumference of the circle was about 50.24 feet, and the diameter of the circle was 16 feet. Which expression best represents the value of π?

Answers

A group of students formed a circle during a game. The circumference of the circle was about 50.24 feet, and the diameter of the circle was 16 feet. The required expression for value of π is: 3.14

What is diameter of circle?

A circle is a form made up of all points on a plane that are at a specific distance from the centre point. In other words, it is the path a moving point in a plane takes to travel around a curve while maintaining a constant distance from another point.

Given that,

The circumference of the circle was about 50.24 feet,

And the diameter of the circle was 16 feet

We have to determine,

Which expression best represents the value of π.

According to the question,

Circumference of the circle = 50.24 feet

Diameter f the circle = 16 feet

Then,

Circumference of the circle = π × d

Circumference of the circle = 50.24 feet

Therefore,

50.24 = π × d

or. π × 16 = 50.24

or,  π = 3.14

Hence, The required expression for value of π is: 3.14

The park district is building new bleachers for the softball feild. One row of bleachers will seat 9 people. What is the minimum number of rows needed to seat atleast 150 people?

Answers

Answer:

17

Explanation:

First, we observe that 1 row will seat 9 people.

Second, we take 150 and divide that by 9 to get our conversion factor for the amount of bleachers that are needed. Our answer comes out to 16.67, which we can assume that the question is asking for enough to seat all 150 of those people.

So we round up to 17, since 16.67 bleachers simply doesn't exist.

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.

a2 = -6

an = 2(an-1 - 3)

Start by calculating a3 using:

a3 = 2(a2 - 3)

This gives

a3 = 2 * (-6 - 3)

a3 = -18

Calculate a4 using:

a4 = 2(a3 - 3)

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

2p+3−2p>−6

Combine 2p and −2p to get 0.

This is true for any p.

Step-by-step explanation:

Hope this helps! :)

Answer:

C. No solution

Step-by-step explanation:

Sove for p;

2p + 3 > 2 (p – 3)

First: distribute 2 (p – 3):

2 (p – 3)

2(p) + 2(-3)

2p - 6

Now add it back to your original problem:

2p + 3 > 2p - 6

Subtract 3 from both sides of the equation:

2p + 3 > 2p - 6

     - 3         - 3

2p > 2p -9

Subtract 2p from both sides of the equation:

2p > 2p -9

-2p -2p

0 > -9

Therefore, this inequality has no solution, because we could solve for p.

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

The area of a triangle is
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

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
