x(t) = 20t
y(t) = 40t - 5t^2
Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y
x(5) = 20(5) becomes x(5) = 100
y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75
The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75
Answer: 0.75
Velocity=distance/time
v=d/t
So in this case:
v=(3mi/5)/(3hr/8) that's the equation you need to solve.
v=(3m/5)*(8/3hr)
8/5 mph=(3m/5)*(8/3hr)
1 3/5 mph= (3/5)/(3/8)
So the first statement is correct.
4.5; 27 * 6 = 162 and then do 162/36 which is 4.5
The art sculpture was 70 inches aka 5.9feet tall and if we round it well it would be 6feet so that would be its highest piont
0.4 is 100% - because it's the output value of the task. <span>If 0.4 is 100%, so wyou can write it down as 0.4=100%. </span><span>We know, that x is 15% of the output value, so we can write it down as x=15%. so your anser is 15</span>
