Part 1: the function would be
h(t)= -16t^2+15t+6.5
Part 2: using the same steps it stated on the calculator
x=1.26
Part 3: by using t= -b/(2a) 15 as b and -16 as a makes it
t= 15/32
Part 4: You then put 15/32 in for t in the equation making the maximum height
10.02
IDK IF THIS IS RIGHT BUT IVE SPENT ALL DAY ON THIS
Five because it's 15 divided by 3 because it's one third
11.46% is the percent increase
The commutative property is a property of <em>addition</em>, not of <em>subtraction</em>. It can work in a subtraction problem if you keep the sign with the number, so you're adding positive and negative numbers.
3 - 6 + 5
= (3) + (-6) + (5)
= (3) + (5) + (-6)
= 3 + 5 - 6
Answer:
21y
Step-by-step explanation:
Well, first take a look at what exactly an LCD is. You want the lowest common multiple of the denominators aka the bottoms of the fractions.
The two denominators you have are 3y and 7y. What multiplication or division can you do to make these two equal? Go through your multiples of 3 and 7 (think times tables) and see where they finally have one in common.
3, 6, 9, 12, 15, 18, 21, 24...
7, 14, 21, 28, 35...
So, between these two lists, we can see that the lowest multiple these two numbers have in common is 21. You could go higher and higher, but your question wants the lowest, so only 21 will do that for you. To make 3y and 7y equal, you need to multiply your first term by 7/7 and your second term by 3/3. If you do that, you'll see your least common denominator is 21y.
