Step-by-step explanation:
One gallon = 25 miles
8 gallon= 25×8 miles= 200 miles
It would be the first table. As you can see there is a pattern, every hour the temperature increases by 6 degrees. Since this pattern is throughout the whole table that is the correct answer. You could also graph the points, time on the horizontal axis and temperature on the vertical axis, it will create a straight line. (That’s the best I could explain it). Also the second table would be exponential, which is not proportional...
Answer:
12. 10.5 cm
13. 16 m
14. 8 m
15. 50.24 m
16. 200.96 m2
17. (16+4 =20 ÷2 =10 ·10·π =314 ÷2 =157) + (16·4 =64) =221 in2
18. (1.1 · 1.2 =1.32) + (1.2 · 4 =4.8 ÷2 =2.4) =3.72 in2
19. 10·5=50
20. c.(1/2 d)^2·π
Answer:
y-1=x^2
Step-by-step explanation:
That is the equation of a parabola with vertex at (0,1). The equation is y-1=x^2.
