Potential energy is a stored energy, which  is caused by the gravitational pull of the earth, that is why when you go up the potential energy will increase. to calculate the mass, just substitute the given to the formula and solve for m

PE = m x g x h
4620 = m x 9.8 x 8.4
m = 4620 / ( 9.8 x 8.4)
m = 56.1 kg is thr mass of the man

Determine the miles traveled in 5 hours at a rate of 189 miles in 3 hours
Salsk061 [2.6K]
Hey there,

Question : <span>Determine the miles traveled in 5 hours at a rate of 189 miles in 3 hours

Answer :
3 hours = 189 miles
1 hour = 189 miles / 3 hours
           = 63 miles
5 hours = 63 miles x 5 hours
             = 315 miles

What is equivalent to -1/3t=4/3​
stepan [7]

<u>Answer:</u>

The equivalent of -1/3t = 4/3​ is t = -4

<u>Solution:</u>

Need to determine such value of t so that when it is multiplied by -1/3, we should get 4/3

That is we need to solve following expression for value of t.

-\frac{1}{3} t=\frac{4}{3}

On multiplying both the sides by 3 we get

\begin{array}{l}{-\frac{1}{3} t \times 3=\frac{4}{3} \times 3} \\\\ {=>-t=4}\end{array}

Now multiplying both the sides by -1 we get

\begin{array}{l}{-t \times-1=4 \times-1} \\ {=>t=-4}\end{array}

Let’s recheck the value of t

-\frac{1}{3} t=-\frac{1}{3} \times-4=\frac{4}{3}

Hence for t = -4, expression -1/3 t is equal to 4/3.

Find sin 0, sec 0, and tan 0, where is the angle shown in the figure.
matrenka [14]

Answer:

Let \ base = x\\5^2 = x^2 + 4^2\\25-16 = x^2\\9 = x^2\\x = 3\\\\\\opposite = 4\\adjacent = 3\\hypotenuse = 5\\Sin \theta = \frac{opposite}{hypotenuse} = \frac{4}{5}   \\\\Cos\theta = \frac{adjacent}{hypotenuse} =\frac{3}{5}\\\\Tan \theta = \frac{opposite}{adjacent} = \frac{4}{3}
