Answer:
$171.12
Step-by-step explanation:
Including the tip and cost, it is 171.12. Multiply 148.6 by 1.15, which includes the total cost plus another 15% for the tip.
Answer:
B) P = 8x + 4
Step-by-step explanation:
Formula:
P= 2( l + w)
P = 2( x + 2 + 3x)
P = 2(4x + 2)
P = 8x + 4
The linear speed of the object is the ratio between the measure of the arc it had traveled and the time. For the length of the arc,
2π x (20 m) x (0.2 rad/ 2π rad) = 4 meters
Divide this by the time, 10 s. Thus, the linear speed is equal to 0.4 m/s.
To find the distance between the points given in the figure of the problem above, you must apply the formula for calculate the distace between two points, which is shown below:
d=√[(x2-x1)^2+(y2-y1)^2]
When you substitute the values, you obtain:
d=√[(x2-x1)^2+(y2-y1)^2]
d=√[(-1-2)^2+(-5-5)^2]
d=10.4
The answer is:10.4
