Answer:
D
Step-by-step explanation:
Since James gave Malcolm a head start of 20 feet, Malcolm's line should start at 20 feet. So that rules out A. They were obviously going further so they went more feet, So C is ruled out because it shows them not moving, plus James didn't get a 15 foot head start which is what the C graph shows. Finally it's not B because if you look at the key at the bottom of every graph, it says that Malcolm is the dotted line, and B shows James getting a 20 foot head start, not Malcolm.
Hope this helps!
Answer:
8 cm
Step-by-step explanation:
Megan's scale of drawing : car is 3cm : 2m
or
3 cm drawing ---> 2m actual length
1 cm drawing ---> (2/3) m actual length
Given Megan's drawing is 6 cm, hence,
6 cm drawing ----> (2/3) x 6 m = 4 m
Hence the actual car is 4 m long
Ivan's scale of drawing:car is 2cm : 1m
or
1 m actual length ---> 2 cm drawing
we know from above that the actual car is 4m long, so
4m actual length ---> 2cm x 4 = 8 cm drawing length.
(x-7)^2+y^2=225={x-7- 225-y2}
x=225-y2+7
