Answer:

Length of the pendulum will be 254 centimeters.

Step-by-step explanation:

In this question the formula to calculate the time period is given and we have to measure the length of new pendulum to be replaced with.

Formula is $T= 2\pi \sqrt\frac{L}{980}$ centimeters

Given parameters is T = 3.2 seconds

By putting the value of T in the formula

$3.2 = 2\pi \sqrt{\frac{L}{980} }$

$\frac{3.2}{2\pi } =\sqrt{\frac{L}{980} }$

$(\frac{1.6}{\pi })^{2} = \frac{L}{980}$

$L = (\frac{1.6}{\pi })^{2}(980) = \frac{2508.8}{(3.14)^{2} }$

L = 254 centimeters.

Answer:

Choice B is correct answer.

Step-by-step explanation:

We have given the time period of pendulum.

We have to find the the length of pendulum.

We have given the formula for time period of new pendulum.

T = 2π√L/980

Separating the length from above formula, we have

T² = 4π²(L/980)

980×T² = 4π²× L

L = 980T² / 4π²

Putting the given value of T, we have

L = 980(3.2)² / 4π²

L = 980(10.24) / 4π²

L = 254 centimeters

Hence, the length of new pendulum is 254 centimeters.

A particular algebra text has a total of 1382 pages which is broken into two parts the second part of the book has 64 more pages

AlladinOne [14]

Answer:

the first part of the book has 659 pages and the second part has 723 pages

Step-by-step explanation:

First we have to raise 2 equations, one that shows us the relationship between one part of the book and the other, and another equation that shows us that together they give us the total of pages

x = second part

y = first part

x = y + 64

x + y = 1382

As the first equation tells us that x = y + 64 we will replace x in the second equation with (y + 64)

x + y = 1382

(y + 64) + y = 1382

y + y = 1382 - 64

2y = 1318

y = 1318/2

y = 659

now we replace in the first equation to y by its value

x = y + 64

x = 659 + 64

x = 723

so the first part of the book has 659 pages and the second part has 723

Circle T is shown. Line segment Q S is a diameters. Point R is opposite of point T. Lines are drawn from points Q and S to point

The value of angle x of the given cyclic segment is; 49.5°

<h3>How to find the angle of an arc?</h3>

We are given the measure of the angle of arc QS as (4x – 18)°

Now, to find the measure of arc QS, this angle is to be equal to 180° and as such;

Thus;

(4x – 18)° = 180°

4x - 18 = 180

4x = 180 + 18

4x = 198

x = 198/4

x = 49.5°

The angle subtended by the arc at the center of a circle with center C is the angle of the arc. It is denoted by. m AB, where A and B are the endpoints of the arc. With the help of the arc length formula, we can find the measure of arc angle.

The formula to measure the length of the arc is;

Arc Length Formula (if angle θ is in degrees); s = 2πr (θ/360°)

Arc Length Formula (if θ is in radians) s = ϴ × r.

Thus, the value of x of the given cyclic segment is; 49.5°
