balu736 [363]

Answer:

15.8

Step-by-step explanation:

The formula would be V = Bh, the Base being LxW.

Since we already know the base and volume, we can substitute it into the formula.

306.52 = 19.4(h). Divide by 19.4, and you get 15.8 as your answer.

A street light is mounted at the top of a 15-ft-tall pole. A man 6 feet tall walks away from the pole with a speed of 5 ft/s alo

harina [27]

Answer:

25/3 ft/s

Step-by-step explanation:

Height of pole , h=15 ft

Height of man, h'=6 ft

Let BD=x

BE=y

DE=BE-BD=y-x

All right triangles are similar

When two triangles are similar then the ratio of their corresponding sides are equal.

Therefore,

$\frac{AB}{CD}=\frac{BE}{DE}$

$\frac{15}{6}=\frac{y}{y-x}$

$\frac{5}{2}=\frac{y}{y-x}$

$5y-5x=2y$

$5y-2y=5x$

$3y=5x$

$y=\frac{5}{3}x$

Differentiate w.r.t t

$\frac{dy}{dt}=\frac{5}{3}\frac{dx}{dt}$

We have dx/dt=5ft/s

Using the value

$\frac{dy}{dt}=\frac{5}{3}(5)=\frac{25}{3}ft/s$

Hence, the tip of his shadow moving with a speed 25/3 ft/s when he is 45 feet from the pole.

Solve for F ------- 2/3 + f = 1/5 A= 13/15 B= 7/15 C= - !3/15 D= - 7/15

nikdorinn [45]

$\\ \sf\longmapsto \dfrac{2}{3}+f=\dfrac{1}{5}$

$\\ \sf\longmapsto f=\dfrac{1}{5}-\dfrac{2}{3}$

$\\ \sf\longmapsto f=\dfrac{3-10}{15}$

$\\ \sf\longmapsto f=\dfrac{-7}{15}$
