The object's maximum height is the same as the y-coordinate of the vertex.To find that, first, finds the x- coordinate(t).You can find it by:
first identifying a,b and c.Multiply the b by negative 1 or simply change its sign and divide it by 2a.Afterward, plug the answer in the equation to find y, your answer.
(ax+bx²+c=-16t²+64t+80). Therefore, a=-6, b= 64 and c=80
-64/2(-16)=-64/-32=2
-16(2)²+64(2)+80=144 ft
So the maximum height of the object, when launched 64ft/sec from a platform that is 80 ft high, is 144 ft
Hope this helps(there are other methods)
Step-by-step explanation:
1. 5+2+3=5+(2+3) 2. 9a is equivalent to 11a-2a 3. 7a + 04 - 2a is equivalent to 7a + -2a + 4 4. 8a-(8a-8) is equivalent or = to 8.
Answer: Total = $200
Step-by-step explanation:
<u>Given information</u>
Money spent on shoes = $20.00
Percent of Money spent on shoes = 10%
<u>Given formula</u>
The total amount of money spent × Percent = Money spent on shoes
⇵
The total amount of money spent = Money spent on shoes / Percent
<u />
<u>Substitute values into the given formula</u>
The total amount of money spent = Money spent on shoes / Percent
Total = (20.00) / (10%)
<u>Convert percentage into decimal</u>
Total = 20.00 / 0.1
<u>Simplify the fraction</u>
Hope this helps!! :)
Please let me know if you have any questions
Answer:
1. Take a=4, b=6
a+b
=4+6
=10( Both are positive integers)
2. a=4 , b= -6
then 4 + (- 6)
= 4 - 6
= -2 [Smaller is positive integer and larger is negative integer , So subtract smaller from larger and apply the sign possessed by larger integer]
3. a = -4, b= -6
a+ b
= -4 -6
=-10 [ Both are negative integers add them apply - sign before the number.]
4. a = -4, b=6
a +b
= -4+ 6
= 2 [one is positive and other is negative subtract smaller from larger and apply positive sign before the number.]
