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

the word problem could be in a box of chocolates there is 3 rows and 2 chocolates in each row how many chocolates are there total.
Answer:
C. 500 ft
Step-by-step explanation:
If we want to make it all equal, we can divide the 2,000 ft by 4 because we have 4 equal descents.
2000 ÷ 4 = 500
He should travel <u>500 feet</u> in each descent.

it’s actually very simple, all you have to do is plug in whatever value you want for x and then solve the problem. once you have done that you put it in this format: (x,y)
for example, the first ordered pair that i told you: (1,1)
i got this by first deciding to use 1 as my x-value, then plugging it into the equation, so it was y=2•1-1. from there you just solve for y, which is very simple. make sure you remember order of operations though, or you could get it wrong! from that step i just put it in ordered pair format, or (x,y). this made my first ordered pair, which was (1,1). you can use the same steps for all ordered pairs you want to find. i hope this helps!
