Four plumbers estimated the length of the radius of a cylindrical pipe. The estimates made by the plumbers are listed. Which list shows these lengths in order from greatest to least?

Answers

Answer:

$(√(3))/(11)>(\pi )/(24)>(3)/(25)>(9)/(100)$

Step-by-step explanation:

To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

$(3)/(25), (√(3))/(11), (9)/(100),(\pi )/(24)$

LCM of the denominators,

2 | 25 11 100 24

2 | 25 11 50 12

5 | 25 11 25 6

5 | 5 11 5 6

1 11 1 6

LCM = 2×2×5×5×6×11 = 6600

$(3)/(25)=(3)/(25)* (264)/(264)$

$=(792)/(6600)$

$(√(3))/(11)=(√(3) )/(11)* (600)/(600)$

$=(600√(3))/(6600)=(1039)/(6600)$

$(9)/(100)=(9)/(100)* (66)/(66)$

$=(594)/(6600)$

$(\pi )/(24)=(\pi )/(24)* (275)/(275)$

$=(275\pi )/(6600)$

$=(864)/(6600)$

Now we can arrange these fractions in the order of greatest to least.

$(1039)/(6600)>(864)/(6600)>(792)/(6600)>(594)/(6600)$

$(√(3))/(11)>(\pi )/(24)>(3)/(25)>(9)/(100)$

I need help finding the radius to this question:Circle o is represented by the equation (x+2)^2 + (y-5)^2=48.The coordinates of the center and the length of the radius of circle O are....

Answers

I'm sorry I can't think of a way to explain this right now. Maybe my brain
is just fried from a long day, I don't know. I really hate it when people get
on here and hand out answers with no explanation, but that's the best that
I can do right now.

I can tell you that the center of the circle is the point (-2, 5),
and the length of the radius is √48 = 4√3 = about 6.928 .

To find the center you would set (x+2) and (y-5) equal to 0. Solving for x and y, you get that x=-2 and y=5. Center: (-2,5). You can also think of this as solving for the additive inverse of 2 and -5. To find the radius, simply take the square root of 48, leaving you with 4√3.
Remember the from is (x-h)²+(y-k)²=R² To find R just take the square root of the constant.

A ball is thrown straight up from the top of a 40 feet tall building with an initial speed of 24 feet per second. The height of the ball as a function of time can be modeled by what function h(t) = _________________ 1. after how many seconds the ball hit the ground. 2.What is the maximum height of the ball? 3.How long did it take for the ball to reach its maximum height?

Answers

Answer:

1)The ball hits the ground after 3 seconds.

2)The maximum height of the ball is 49 feet

3)It takes 1.25 seconds to reach its maximum height

Step-by-step explanation:

Height of building = 40 feet

We are given that A ball is thrown straight up from the top of building with an initial speed of 24 feet per second.

So, The height of the ball as a function of time can be modeled by: $h(t)=-16t^2+40t+24$

1)After how many seconds the ball hit the ground.

Substitute h(t)=0

So, $-16t^2+40t+24=0\n-2t^2+5t+3=0\n2t^2-5t-3=0\n2t^2-6t+t-3=0\n2t(t-3)+1(t-3)=0\n(2t+1)(t-3)=0\nt=(-1)/(2) , 3$

Since time cannot be negative

So,the ball hits the ground after 3 seconds.

2)What is the maximum height of the ball?

It takes maximum height at vertex

Formula : $t = (-b)/(2a)$

$t=(-40)/(2(-16))=1.25 seconds$

Substitute the value of t in function

$h(1.25)=-16(1.25)^2+40(1.25)+24\nh(1.25)=49 feet$

So,the maximum height of the ball is 49 feet

3).How long did it take for the ball to reach its maximum height?

It takes 1.25 seconds to reach its maximum height

Answers

Answer:

144°

96+48(further away angles)

Answer:

x = 144°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle , then

x = 48° + 96° = 144°

A straight line has an equation y= 4x=5 Write down the equation of the straight line that is parallel to y=4x-5 and passes through the point (0,3).

Answers

Parallel lines have same slope but different y-intercept. So they gave the equation y=4x-5 and the (0,3) where 3 is the y-intercept.

So the equation would be y=4x+3. HOPE THIS HELPS!!!!!!!!

If it is parallel then it has the gradient which is 4 so the equation will be
y = 4x + ?

now to find the y intercept, using the coordinates, x is already 0 so the y intercept is 3

meaning the equation is
y = 4x + 3
