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
Answer:
27
Step-by-step explanation:
If the ratio is 1:3 multiply that by 9:9 so you effectively get 9:9x3 = 9:27. Or, you can say to yourself if B (3) is 3 times greater than A (1) then B is 3 times greater than 9. So 9x3 = 27
Answer:
(c) {13,16,30}
Step-by-step explanation:
In order for the sides lengths to form a triangle, the sum of the shortest two must exceed the longest.
That will not be the case for ...
{13, 16, 30}
because 13 +16 = 29 < 30.
(13, 16, 30} could not form a triangle
