What is the ratio between KE and velocity?

1 answer:

8 0

Kinetic Energy (KE) is equal to half of an object's mass (1/2*m), multiplied by the velocity squared.

This would be represented by the equation:
Ek = 1/2*mv^2

Find the missing side of the right triangle. Side a = 10 and side b = 5

Levart [38]

Assuming that C is the hypotenuse...

The formula you want to use is:

a^2 + b^2 = c^2

We start by squaring 10, which is 100. 5^2 is 25. Now that we have the values, we can do the equation.

100+25=c^2 100+25= $\sqrt{125}$

Now, square root $\sqrt{125}$

C= 11.180

Vedmedyk [2.9K]

Answer:

Hence, the probability of a Negative test is $P(T^C)=0.5904$ .

Step-by-step explanation:

(a)

Let $D=$ Drug user and $T=$ Test positive

Probability of drug users $P(D)=36\%=0.36$

$P(\frac{T}{D})=96\%=0.96$

$P(\frac{T^c}{D^c})=90\%=0.90$

(b)

Find the Probability of a Negative test,

$P(T^C)=P(\frac{T^C}{D^C})\cdot P(D^C)+P(\frac{T^C}{D})\cdot P(D)$

$\Rightarrow P(T^C)=0.9\cdot(1-0.36)+(1-0.96)\cdot 0.36$

$\Rightarrow P(T^C)=0.9\cdot 0.64+0.04\cdot 0.36$

$\Rightarrow P(T^C)=0.576+0.0144$

$\Rightarrow P(T^C)=0.5904$

The volume of a cylinder is given by the formula <img src="https://tex.z-dn.net/?f=V%2B%20%5Cpi%20r%5E2h" id="TexFormula1" title

n200080 [17]

V = $\pi r^{2}h$ where r is radius and h is height

so when radius is (x+8) and height is (2x+3),

volume = $\pi (x+8)^{2}(2x+3)$
