Uniform circular motion is used in physics to describe the motion of an object traveling at a constant speed in a circle. The sp

eed of the object is called tangential velocity and it can be calculated using the formula above, where r is the radius of the circle and T is the time is takes for the object to make one complete circle, called a period. Which of the following formulas could be used to find the length of one period if you know the tangential velocity and the radius of the circle?

Answer:

  B)  T = 2πr/v

Step-by-step explanation:

To solve the given equation for T, multiply it by T/v.

v=\dfrac{2\pi r}{T}\\\\v\dfrac{T}{v}=\dfrac{2\pi r}{T}\cdot\dfrac{T}{v}\\\\T=\dfrac{2\pi r}{v} \qquad\text{simplify}

Find the sine of ∠U.<br><br> A)48/55<br> B)48/73<br> C)55/48<br> D)55/73
charle [14.2K]

Answer:

D) 55/73

Step-by-step explanation:

The question is on trigonometry. Sine of an angle is obtained using the SOH of SOHCAHTOA formula of trigonometry. SOH is an acronym for sine, opposite and hypotenuse. Sine of an angle is obtained from the ratio of opposite and hypotenuse of a given triangle. Thus, SOH

is denoted as stated below.

sine \:  \beta  =  \frac{opposite}{hypotenuse}

Hence, given the above triangle,

sine \: of \: angle \: u =  \frac{ |bc| }{ |ab| }  =  \frac{55}{73}

Therefore, the sine of angle u = 55/73 (D)

The function f(x) is vertically compressed to form g(x) while the function f(x) is vertically compressed and then reflected across the x-axis to form h(x)

<h3>How to compare both functions?</h3>

The functions are given as

f(x) =x^2

g(x) =3x^2

h(x) = -3x^2

Substitute f(x) =x^2 in g(x) =3x^2 and h(x) = -3x^2

g(x) =3f(x)

h(x) = -3f(x)

This means that the function f(x) is vertically compressed to form g(x)

Also, the function f(x) is vertically compressed and then reflected across the x-axis to form h(x)

See attachment for the functions g(x) and h(x)

Also, functions f(x) and g(x) have the same domain and range

While functions f(x) and h(x) have the same domain but different range

The complete table is:

x      -2    -1    0   1    2

g(x)  12    3    0    3   12

h(x)  -12    -3    0    -3   -12

Solve for m. (-11/6) + m = -2/9
3241004551 [841]

Answer:

m = \frac{29}{18}

Step-by-step explanation:

=> (-11/6) + m = -2/9

Adding 11/6 to both sides

=> m = -\frac{2}{9} + \frac{11}{6}

LCM = 18

=> m = \frac{-4+33}{18}

=> m = \frac{29}{18}
