Answer:

height = 56.7

Step-by-step explanation:

Using sohcahtoa method:

\frac{opposite}{hypotenuse} =sin(x)

A pendulum is 45 cm long. When it swings, it travels along the arc of a circle and covers a distance of 27.5 cm. Calculate the a
11Alexandr11 [23.1K]

Answer: The angle through which the pendulum travels = 35^{\circ}.

Step-by-step explanation:

Formula: Length of arc: l= r\theta , where r= radius ( in radians) , \theta = central angle.

Given: Length of pendulum (radius) = 45 cm

Length of arc= 27.5 cm

Put these values in the formula, we get

27.5=45\theta\\\\\Rightarrow\theta=\dfrac{27.5}{45}=\dfrac{275}{450}\\\\\Rightarrow\ \theta=\dfrac{11}{18}\text{ radians}

In degrees ,

\theta=\dfrac{11}{18}\times\dfrac{180}{\pi}=\dfrac{110\times7}{22} \ \ \ \    [\pi=\dfrac{22}{7}]

\theta=35^{\circ}

Hence, the angle through which the pendulum travels = 35^{\circ}.

HELP PLEASE!!! <br>the question and answer are in the image attached​
RideAnS [48]

Answer:

g(x)=\sqrt[3]{x-3}+4

Step-by-step explanation:

The function g(x) is a shifted version of the function f(x); f(x) is shifted by 3 along x-axis and by 4 along y-axis.

Another way of thinking about this is that the function g(x) contains points (3, 4); therefore,

g(x)=\sqrt[3]{x-3}+4

which goes through the point (3, 4).
