A sail is in the form of a right triangle that is three times as high as it is wide. The snail is made from 6 square meters of m

lara31 [8.8K]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

Suppose the base of right triangle sail is b

Suppose the height of right triangle sail is h

It is given that, it is three times higher as it is wide.

$h=3b$

Area of right triangle is A = $\frac{1}{2}*b*h$

$6=\frac{1}{2}*b*h$

Plugging the value of h in terms of b

$6=\frac{1}{2}*b*(3b)$

$b^2=4$

$b=2$

Hence height h = $3*2 = 6$

Hecne the height of sail is 6 meters. : Answer

Hope it will help :)

A particle is moving horizontally along the x-axis. Its position (in ft) is: s(t)=t^3-18t^2+33t+14 where t is in sec.

UNO [17]

Answer:

t=11 sec

Step-by-step explanation:

The position of the particle moving along the x-axis is given by:

$s(t) = {t}^{3} - 18 {t}^{2} + 33t + 14$

The velocity is given by:

$s'(t) = 3 {t}^{2} - 36{t} + 33$

If s'(t)>0 then the particle is moving right.

$3 {t}^{2} - 36{t} + 33 \: > \: 0 \\ {t}^{2} - 12{t} + 11\: > \: 0$

$\implies \: t \: < \: 1 \: or \: t \: > \: 11$

This means that the particle is moving left when

$1 \: < \: t \: < \: 11$

The particle changes direction at time t=1 or t=11
