Your relay team competes in the 4 x 400 meter relay. The individual times for your four member team are 56.25, 59.89, 58.55, and 55.48 seconds. What is the total relay time for the team?

The total relay time for the team is 230.17 seconds.

Given information:Your relay team competes in the 4 x 400 meter relay. The individual times for your four-member team are 56.25, 59.89, 58.55, and 55.48 seconds.

Calculation of total relay time:= 56.25 + 59.89 + 58.55 + 55.48

= 230.17 seconds

Consider the line parameterized by x = 5 − 4t, y = 3 + 8t, z = 10t. find an equation of a plane so that the plane is perpendicular to the line and through the point (2, 5, 1).

Answer:

2x-4y-5z +21 =0 is the equation.

Step-by-step explanation:

Given the line can be written as

The line has direction ratios (-4, 8, 10)

Since the plane is perpendicular to this line, this line is normal to the plane.

It passes through (2,5,1)

Hence plane will have equation as

-4(x-2)+8(y-5)+10(z-1) =0 Or

-4x+8y+10z +8-40-10 =0

4x-8y-10z +42 =0

Divide by 2

2x-4y-5z +21 =0
