I think 4: 10 and 6:15 are equal
You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.
|-1 - (-7)| = |-1 + 7| = |6| = 6
The distance is 6 units
Answer:
f(x) = -(x+4)^3
Step-by-step explanation:
Reflection over the x-axis negates every y-coordinate. The reflected function is ...
f(x) = -(x+4)^3
Answer:
1) The velocity at this time is of meters per second.
2) The velocity at this time is of meters per second.
Step-by-step explanation:
This question involves concepts of derivatives.
The velocity is the derivative of the position.
We use these following derivatives:
1) s = 1 + 9(cos t)
Find the body's speed at time t=pi/3 sec.
We have to find the derivative at . So
is a common angle, which has a sine of . So
The velocity at this time is of meters per second.
2) s = 12(sin t) - (cos t)
Find the body's velocity at time t=pi/4 sec.
We have to find the derivative at . So
is a common angle, which has both sine and cosine of . So
The velocity at this time is of meters per second.
Answer:
21
Step-by-step explanation:
KL = 12
LM = 9
12 + 9 = 21
KM = 21
