Part A: What does the x-intercept of the function for car 1 represent? (2 points)
For this case, the intersection with the x axis means that car 1 has reached its destination. He traveled 70 km in 70 minutes.
Part B: What does the y-intercept of the function for car 2 represent? (2 points)
For this case, the intersection with the Y axis represents that car 2 must travel 70 km to reach its destination and that it has not yet started its journey.
Part C: What is the domain of the functions for car 1 and car 2? (2 points)
car1:
The domain of the function for this car are all x that range from 0 to 70. Mathematically it can be written as [0, 70].
car 2:
The domain of the function for this car are all x that go from 0 to more infinity. Mathematically it can be written as [0, inf)
Part D: What is the average rate of change from x = 30 to x = 40 for the function representing the motion for car 2? What is the value of this average rate of change?
For the domain between x = 30 and x = 40 the rate of change of the function of the car 2 is 34.69144.
This means that car 2 travels 34.69144 km approximately in 10 minutes. As the slope is negative, then the car is getting closer to its destination.
Answer:
answer is c
Step-by-step explanation:
For the third circle, in the first row, the answer is 4
For the third circle, in the second row, the answer is 20
For the third circle, in the third row, the answer is 20
For the circles in the first row:
For the first circle,
5 × 2 = 10 ; 10 ÷ 2 = 5
For the second circle,
3 × 4 = 12; 12 ÷ 2 = 6
∴ For the third circle,
2 × 4 = 8; 8 ÷ 2 = 4
∴The answer is 4
For the circles in the second row:
For the first circle,
4 × 5 = 20; 20 - 8 = 12
For the second circle,
6 × 5 = 30; 30 - 17 = 13
∴ For the third circle,
5 × 5 = 25; 25 - 5 = 20
∴ The answer is 20
For the circles in the third row:
For the first circle,
16 ÷ 4 = 4; 4 + 4 = 8
For the second circle,
24 ÷ 4 = 6; 6 + 6 = 12
∴ For the third circle,
40 ÷ 4 = 10; 10 + 10 = 20
∴ The answer is 20
Hence,
For the third circle, in the first row, the answer is 4
For the third circle, in the second row, the answer is 20
For the third circle, in the third row, the answer is 20
<span>the area of Alaska - 1 700 000 square kilometers
and we are told that the land area of Florida is 1/10th the size of Alaska. Therefore land area of Florida is equal to 1/10th of 1 700 000
that's 1 700 000 / 10 = 170 000 km</span>²<span>
therefore land area of Florida is 170 000 km</span>²
