In the month of March, the temperature at the South Pole varies over the day in a periodic way that can be modeled approximately

by a trigonometric function. The highest temperature is about -50^\circ C−50 ∘ Cminus, 50, degrees, C, and it is reached around 2\text{ p.m.}2 p.m.2, start text, space, p, point, m, point, end text The lowest temperature is about -54^\circ C−54 ∘ Cminus, 54, degrees, C and it is reached half a day apart from the highest temperature, at

Answer:

2am

Step-by-step explanation:

We know that the temperature variation is depicted by trignometric function. The total cycle of any trignometric function can be divded into four parts. In first quarter of the cycle, the value rises from mean to max. In 2nd quater, it falls to mean again. In third quarter it lowers to minimum and in last quarter rises to mean again.

Dividing the daily temperature variation cycle into four quaters of 6 hours each.  The difference in time for any trignometric function to reach from its maximum value to minimum value is one-half of the cycle. In this case, it will be 12 hours.

Therefore daily temperature will fall to its minimum value 12 hours after reaching maximum that is at 2 am

Train a travel 175 miles in a four hours. for train b y=43.5x represents its rate of speed over the same 4 hours which train tra
stepan [7]

Answer:

Train A is faster by a factor of 1.01

Step-by-step explanation:

Given:

Train A:

Distance = 175 Miles

Time = 4 Hours

Train B:

y=43.5x

To Find:

which train travels at a faster rate in by what factor  =?

Solution:

The speed of the train A = \frac{Distance}{time}

The speed of train A  =\frac{175}{4}

The speed of train A = 43.75 miles per hour

Speed of the train B is the slope of the given line

The standard equation of the slope of the line is

y = mx+b

where m is the slope

and we are given with

y = 43.5x

So comparing with the standard equation

m = 43.5

Hence the speed of train B is 43.5  miles per hours

Train A travels faster

Rate =\frac{\text{speed of train A}}{\text {Speed of train B}}

rate  = \frac{43.75}{43.5}

rate  =1.01

The radius of a sphere is increasing at a rate of 5 mm/s. how fast is the volume increasing when the diameter is 60 mm? evaluate
mamaluj [8]
The diameter of the sphere is 60 mm which means its radius is 30mm. <span>The radius of a sphere is increasing at a rate of 5 mm/s. 
The formula for the radius when the time is x second would be:
</span>r(t)<span>= 30+ 5x
dr/dt= 5

The speed of </span><span>volume increase </span><span>of the sphere volume would be derived from sphere volume: 
</span>V(r)=4/3* pi * r^3<span>
dV/dt= 4/3 * pi * 3r^2 * (dr/dt) =4/3* pi * 3(30)^2 * 5 =  18000 pi= 56571 mm^3/s</span>
