In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the t
ozzi

Answer:

C: 31 m/s

Step-by-step explanation:

It falls from a dam.

Thus;

Initial velocity; u = 0 m/s

Height; h = 49 m

Acceleration due to gravity is 9.8 m/s²

To solve for the final velocity this, we will use Newton's third equation of motion;

v² = u² + 2gh

v² = 0² + 2(9.8 × 49)

v = √960.5

v ≈ 31 m/s

Solve using the Pythagorean identity<br>​
Lynna [10]
<h3>\bold{Sin\theta_{1}=-\frac{4}{5}}</h3>

Answer:

Solution given

Cos\displaystyle \theta_{1}=\frac{3}{5}

consider Pythagorean theorem

\bold{Sin²\theta+Cos²\theta=1}

Subtracting Cos²\thetaboth side

\displaystyle Sin²\theta=1-Cos²\theta

doing square root on both side we get

Sin\theta=\sqrt{1-Cos²\theta}

Similarly

Sin\theta_{1}=\sqrt{1-Cos²\theta_{1}}

Substituting value of Cos\theta_{1}

we get

Sin\theta_{1}=\sqrt{1-(\frac{3}{5})²}

<h3>Solving numerical</h3>

Sin\theta_{1}=\sqrt{1-(\frac{9}{25})}

Sin\theta_{1}=\sqrt{\frac{16}{225}}

Sin\theta_{1}=\frac{\sqrt{2*2*2*2}}{\sqrt{5*5}}

Sin\theta_{1}=\frac{4}{5}

Since

In IVquadrant sin angle is negative

\bold{Sin\theta_{1}=-\frac{4}{5}}

Let f(x)=6x. The graph of f(x) is transformed into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 uni
hram777 [196]
K so a translation of 2 units up is just adding 2 to the end of the equation, and a vertical compression of 1/3 means dividing the slope by 3:
so your equation goes from

f(x)=6x (compresses to)
2x (add 2 for the translation)
g(x)=2x+2

Hope this helped.

3x+2(x+4)=5(x+1)+3. Show work please
Nesterboy [21]
First, we distribute the 2 through the parenthesis.

3x+2x+8=5(x+1)+3

Then we distribute the 5 through the parenthesis

3x+2x+8=5x+5+3


Collect the like terms

5x+8=5x+5+3

Add the numbers

5x+8=5x+8

The statement is true for any value of x, because both sides are identical
