Answer:

steps

Step-by-step explanation:

secθ / cscθ + sinθ / cosθ = (1/cosθ) / (1 / sinθ) + sinθ / cosθ

= (sinθ / cosθ) + (sinθ / cosθ) = 2 (sinθ / cosθ) = 2 tanθ

Can someone help me plz
Lapatulllka [165]

Answer:

$15.25

Step-by-step explanation:

Since you know that each mile is $.75 and you traveled 17 miles, you must first multiple 17 times .75 which is $12.75, then add the $2.50 set rate. Therefore you will pay $15.25 for the cab ride.

.75(17) + 2.50 = 15.25

A spherical balloon is inflated so that its volume is increasing at the rate of 3 ft3/min. How fast is the diameter of the ballo
beks73 [17]

When an spherical balloon volume is increasing at the rate of 3ft^3/min then the diameter of the balloon is increasing \frac{3}{2\pi }ft /min

How can we find the rate of change of balloon's diameter ?

The volume of a spherical balloon is v=\frac{4}{3} \pi r^3

In form of diameter we can write as

v=\frac{4}{3} \pi (\frac{D}{2} )^3\\=\frac{1}{6} \pi D^3

Now we will differentiate both sides wrt to t we get

\frac{dv}{dt} =\frac{1}{6} \pi 3D^2 \frac{dD}{dt} \\\frac{dD}{dt} =\frac{2}{\pi D^2} \frac{dv}{dt} \\\\when r=1\\D=2ft

Given in the question \frac{dv}{dt} =3ft^3/min

thus when we substitute the values we get

\frac{dD}{dt} =\frac{2}{\pi *2^2} (3)\\\frac{dD}{dt}=\frac{3}{2\pi }  ft/min

Volume = area of circle × height of cylinder

Step-by-step explanation:

To find the area of the circle (the top of the cylinder), use pi times r squared. Then take that and multiply it by the height of the cylinder. That should be your volume.
