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:
4 (3+x)
Step-by-step explanation:
4 (3+ x) = (4×3) + (4× X ) = 12 + 4x
First off, 2/10 can be simplified. 2 divided by 2 is 1. So the numerator is 1. 10divided by 2 is 5. Denominator is 5. So right now your first fraction is 2/5. 2/5 divided by 1/2. First, you keep your first fraction. You switch the division sign to multiplication, and always do the reciprocal (flip it around) of the second fraction. So instead of 1/2, it would be 2/1. Then multiply. 2/5 x 2/1. 2x2 is 4, 5x1 is 5. 4- numerator/5-denominator. Your answer is 4/5.
