The odometer in a car measures the number of miles driven by the car since it was made. During a trip, the odometer reading in A

nita’s car is modeled by the function y=9500+55x, where x represents the number of hours driven during the trip and y represents the odometer reading in miles.
Part A

What is the meaning of the rate of change in this function?


The number of miles driven each hour during the trip.

The total number of miles driven at the beginning of the trip.

The total number of miles driven at the end of the trip.

The number of miles driven during the trip.

Answer:

Step-by-step explanation:

Part A

The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.

Part B

The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0.  The answer must be 1950.

Choose one of the factors of 6x^3 + 6
ivanzaharov [21]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

6x^3+6

Now, by factorising , we get

6x^3+6\\=6(x^3+1)

Now, we use the formula i.e.

a^3+b^3=(a+b)(a^2-ab+b^2)

By using this, we get ,

6(x^3+1)\\=6(x+1)(x^2-x+1)

So,

(x+1) \text{ is the factor of }6x^3+6.

Acapulco, Mexico and Hyderabad, India both lie at 17° north latitude, and lie very nearly halfway around the world from each oth

In solving this problem we can consider Earth to be a sphere. When we have a circle, then we can use this formula to find arc length:
L=2 \pi R \frac{C}{360}
Where:
L= arc length (in this problem it is disance we need to travel)
R = radius of circle (in this problem it is equal to a radius of Earth)
C = angle we need to pass

We are told that two cities lie halfway around the world. If we fly to west this means angle is 180°.
This gives an arc length of:
L=2* \pi *3960* \frac{180}{360}  \\  \\ L=12440.71 miles

If we want to fly to north we need to go to 90° northern latidtude and then back to 17° latitude. This means angle is:
C=2*(90-17)=2*73°=146°
This gives an arc length of:
L=2* \pi *3960* \frac{146}{360} \\ \\ L=10090.8 miles

We can see that flying north is shorter. It is shorter by:
12440.71 miles - 10090.8 miles = 2349.91 miles
