You need to find the ratio or both x and y.
If their all equal, then it is proportional.
If it’s not equal, it isn’t proportional.
You would need to divide the numbers.
Let’s say that the top number in a table is 9 and the bottom number is 90.
You would divide 90/9 and get 10. If you divide the rest, and their all 10, then it is proportional.
The correct value of the h function is; h= -9.8t² + 45t + 1
Answer:
Using the discriminant, no real solution exists and the baseball will not hit the roof.
Step-by-step explanation:
We are told the height is expressed as;h= -9.8t² + 45t + 1
Also that the Astrodome has a maximum height of 63.4 m
Thus, to find out if the baseball hit at a velocity of 45 m/s will hit the roof, we'll replace h with 63.4m.
Thus;
63.4 = -9.8t² + 45t + 1
Subtract 63.4 from both sides to give;
-9.8t² + 45t + 1 - 63.4 = 0
-9.8t² + 45t - 62.4 = 0
Using quadratic formula, we have;
t = -45 ± √{(45² - (4 * (-9.8) * (-62.4)}
t = -45 ± √(2025 - 2446.08)
t = -45 ± √(-421.08)
The discriminant is -421.08
This value is less than 0.
Thus, no real solution exists and the baseball will not hit the roof.
Answer:
I use to have to do these i no longer have the app but theres an app called desmos and it graphs it fro you and gives you all the domain and rnge stuff all u gotta do is put in the equation avalible on ios and samsun
Step-by-step explanation:
22 because you take the smallest and largest number and subtract them so you do 81-59=22
