$g(t) = t - 2\\h(t) = 3t + 3\\(g \circ h)(t) = g(h(t)) = (3t + 3) - 2 = 3t + 3 - 2 = 3t + 1$

G (3t+ 3)= 3t + 1

Write the problem as a mathematical expression.

h (t) = 3t + 3 , (g o h) (t),
g (t) = t -2

Set up the composite result function.

g (h (t))

Evaluate g(h(t)) by substituting in the value of h into g

g (3t +3 ) = (3t + 3) -2

Subtract 2 from 3

g (3t +3 ) = 3t + 1

A 748-N man stands in the middle of a frozen pond of radius 4.0 m. He is unable to get to the other side because of a lack of fr

Ber [7]

Answer:

The man will take 64 seconds to reach to the south shore of the frozen pond.

Step-by-step explanation:

Given:

Weight of the man = 748 N Mass of the man, $(m)= \frac{W}{g}$ = $\frac{748}{9.8}$ = $76.32$ kg

Radius of the pond $(r)$ = 4 m

Mass of the textbook = 1.2 kg

Velocity at which the textbook is thrown = 4 ms^1

We have to find the velocity of the man after the throw.

Let the velocity is $V_m$ .

Now using law of conservation of momentum we can find the $V_m$ value.

$m_(_b_)V_b_(_i_) +m_(_m_)V_m_(_i_) =m_(_b_)V_b_(_f_)+m_(_m_) V_m_(_f_)$

Considering $V_m_(_f_)=V_m$

And initial velocity of both the man and book i.e $V_b_(_i_)=0,\ V_m_(i_)=0$

So,

⇒ $0 =m_(_b_)V_b_(_f_)+m_(_m_) V_m$

⇒ Plugging the values.

⇒ $V_m=-\frac{m_(_b_)V_b_(_f_)}{m_(_m_)}$

⇒ $V_m=-\frac{1.2\times 4}{76.32}$

⇒ $V_m=-0.062$ ms^-1

Here the negative velocity is meant for opposite direction of the throw.

Numerically we will write, $V_m = 0.062$

With this velocity the man will move towards south.

We have to calculate the time taken by the man to move to its south shore.

And we know $velocity(v)\times time(t) = distance(d)$

Let the time taken be $t$ and $v\times t = d$ and $d=r$ then, $V_m\times t=r$

Then

⇒ $t=\frac{radius\ (r)}{V_m}$

⇒ Plugging the values.

⇒ $t=\frac{4}{0.062}$

⇒ $t =64$ sec

The man will take 64 seconds to reach to the south shore of the frozen pond (circular).

Two angles are supplementary. One angle measures (3x + 2) degrees. The other angle measures twice that amount. What equation cou

nikdorinn [45]

Answer:

I do not know the equations given but here's my equation and solution:

9x = 174°

x = 19 1/9°

Step-by-step explanation:

(3x + 2) + 2(3x + 2) = 180°

3x + 2 + 6x + 4 = 180°

9x + 6 = 180°

9x = 174°

x = 19 1/9

If my answer is incorrect, pls correct me!
