Answer:

The period T (in seconds) of a pendulum is given by T=2\pi \sqrt((L)/(32)), where L stands for the length (in feet) of the pendulum. If \pi =3.14, and the period is 1.57 seconds

Step-by-step explanation:

i am smart

The length of the pendulum is 128 feet.

Time period of a pendulum is defined as the time taken by the pendulum for completing one oscillation.

Here,

Given that,

Time period of the pendulum,

T = 2[tex]\pi[/tex] √(L/32)   where L is the length of the pendulum(in feet)

T² = 4[tex]\pi[/tex]²(L/32)

T²/4[tex]\pi[/tex]² = L/32

So, L = 32 xT²/(4[tex]\pi[/tex]²)

L = 8T²/[tex]\pi[/tex]²

So, putting the value of time period, T = 12.56 s

Length of the pendulum,

L = 8T²/[tex]\pi[/tex]²

L = 128 feet

Hence,

Length of the pendulum is 128 feet.

Your question was incomplete, but most probably will be:

The period T (in seconds) of a pendulum is given by T=2\pi \sqrt((L)/(32)), where L stands for the length (in feet) of the pendulum. If \pi =3.14, and the period is 12.56 seconds, what is the length?

The equation of the table is a linear function; which has a constant rate of change

The equation is given as:

y = 2x + 3

When x = -2, we have:

[tex]y = 2 * -2 + 3 = -1[/tex]

When x = 0, we have:

[tex]y = 2 * 0 + 3 = 3[/tex]

When x = 1, we have:

[tex]y = 2 * 1 + 3 = 5[/tex]

When x = 3, we have:

[tex]y = 2 * 3 + 3 = 9[/tex]

So, the complete table is:

x  -2  -1  0  1  2  3

y   -1   1  3   5  7  9

Answer: B' (5,8), C' (3,1)

Step-by-step explanation:

You can use the points A' (-1,8) and A (-2,-3) to find how many units point A was translated.

-2 + 1 = -1

-3 + 11 = 8

Then, you simply add 1 to the x-values of points B and C and 11 to the y-values of points B and C to get B' (5,8), C' (3,1).

if the shirt was 35% off, then you paid 65% of the cost

that value can be found by:

39 x .65 = 25.35 (this is the amount paid for the shirt)

sales tax of 6% on 25.35 is:

.06 x 25.35 which equals 1.52

The area of a shaded region is the amount of space it occupies

The measurement that is closest to the area of the shaded region is 19 square inches

Start by calculating the area of the big rectangle.

Assume the dimensions of the rectangle are 10 by 15 inches.

The area would be

[tex]A_1 =10* 15[/tex]

[tex]A_1 = 150 in^2[/tex]

Next, calculate the area of the small rectangle.

Assume the dimensions of the rectangle are 13 by 10 inches.

The area would be

[tex]A_2 =13* 10[/tex]

[tex]A_2 =130 in^2[/tex]

Next, calculate the difference between both areas

[tex]d = 150 - 130[/tex]

[tex]d = 20\ in^2[/tex]

19 is the closest to 20

Hence, the measurement that is closest to the area of the shaded region is 19 square inches (using the assumed values)

Answer:

Step-by-step explanation:

Hypotenuse² =base² + altitude²

(3x + 4)² = (2x + 1)² + (3x)²

{Use (a+b)² = a² + 2ab + b²}

(3x)² + 2*3x+4 + 4² = (2x)² + 2*2x*1 + 1² + 9x²

9x² + 24x + 16 = 4x² + 4x + 1 + 9x²

9x² + 24x + 16 = 13x² + 4x + 1

0 = 13x² + 4x  + 1 - 9x²  - 24x - 16

13x² - 9x² + 4x - 24x +1 - 16 = 0

4x² - 20x - 15 = 0

a = 4 ; b =-20  ; c = -15

D = b² - 4ac  = (-20)² - 4*4*(-15) = 400 + 240 = 640

√D = √640 = 25.30

Answer:

66,667

Step-by-step explanation:

We are given this chart to complete.

0            _______      ________   40,000          _______      _______

0%             20%            40%             60%                80%            100%

We see that 60% corresponds to 40,000. That means that since 20% is 1/3 of 60%, then the number corresponding to 20% is 1/3 of 40,000.

40,000/3 = 13,333

40% is twice 20%, so corresponding to 40%, you must have 2 × 13,333.

For 40%, you write 26,667.

80% is 4 times 20%, so for 80%, you write 4 × 13,333 = 53,333.

Finally, 100% is 5 times 20%, so for 100%, you write 5 × 13,333 = 66,667.
