Complete Question:
The expression 16t² represents the distance in feet an object falls after t seconds. The object is dropped from a height of 906 feet. What is the height in feet of the object 2 seconds after it is dropped?
Answer:
H(2) = 842 feet
Step-by-step explanation:
Let the height be H.
<u>Given the following data;</u>
H(t) = 16t²
Height, H = 906 feet
Time, t = 2 seconds
To find the time, t at 2 seconds, we would use the following formula;
H(t) = H - 16t²
H(2) = 906 - 16(2)²
H(2) = 906 - 16*4
H(2) = 906 - 64
<em>H(2) = 842 feet</em>
<em>Therefore, the height in feet of the object 2 seconds after it is dropped is 842.</em>
The value of 4 in 864 is 4...because it is in the ones place
the value of 4 in 846 is 40...because it is in the tens place
40/4 = 10...so the value of the 4 in 846 is 10 times greater then the value of 4 in 864

12 muffins for 4.80 is the better deal.
Explanation: the ratio of $ to muffin for the first deal is .40:1 which is 40 cents per muffin. Compare this to the second deal’s ratio, .45:1, or 45 cents per muffin, which is higher. Thus, the first deal is better
