Part A: 6.2
Part B:6.405
PArt C: The estimate was close to the real answer
Answer:
<h3>3 secs</h3>
Step-by-step explanation:
Given the height of the object as it drops from the observation deck expressed as;
h= -16t^2+152
To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;
8 = -16t^2+152
subtract 8 from both sides
8-8 = -16t^2+152-8
0 = -16t^2+144
0-144 = -16t^2
-144 = -16t^2
16t^2 = 144
Divide both sides by 16;
16t^2/16 = 144/16
t^2 = 9
t = √9
t = 3seconds
Hence it will take 3 seconds for the object to be 8 feet above the valley floor
Answer:
You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.
Step-by-step explanation:
Say you were multiplying 14.63 and 7.74
14.63
<u> x 7.74 </u><em>Always starting from the right side of the equation</em>
.5852 <em>go to the left </em> <em>four digits and put a decimal then </em>
<em> ↑←←←← just carry the decimal down and you'll end up with </em>
10.2410 <em>the final product</em>
<u> + 102.4100 </u>
113.2362
