The speed of car is 64 kilometer per hour
<em><u>Solution:</u></em>
Given that car travelled a distance of D = 320 km for T = 5.0 hours
To find: speed (R) of the car in km per hour
<em><u>Formula given:</u></em>
D = R. T
where "D" is the distance
"R" is the speed of car
"T" is the time taken
<em><u>Substituting the given values in above formula we get,</u></em>
Thus the speed of car is 64 kilometer per hour
We cannot round the answer to nearest tenth, since answer is not in decimal
Answer:
16.2 cm
Step-by-step explanation:
use the pythagoran theorem
a² + b² = c²
15² + 6² = c²
225 + 36 = c²
261 = c²
Take the square root of both sides
16.1554944214 = c
Rounded
16.2 cm
Answer:
129
Step-by-step explanation:
Collinear means that the points X, Y, and Z are on the same line. The question asks for one possible value of YZ, so for this, let's assume point X is between Point Y and Point Z.
This means...
XY+XZ=YZ
54+75=YZ
YZ=129
Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.
We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.
