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)

Answer:
OUR ANSWER IS $61,334.36
Step-by-step explanation:
The real rate of return = 6.19% - 2.5% = 3.69%
We assume the annual withdrawal is P and the same will be withdrawn at the end of each year, so that the present value of the regular annuity will be $1,000,000
Total tenure = 25 Years
PV = 1 × [(1-(1 + r)⁻ⁿ] /r = P × [1 +(1.0369)⁻²⁵] /0.0369 =P× 16.147
But as per the condition, PV = $1,000,000
So P =$1000,000 /16.147 =$61,334.36
Total Score = 10*85=850
Final total after throwing out top and bottom scores = 850-60-92
=698
Therefore Final Average
= 698/8
=87.25
Answer:
The first answer
Step-by-step explanation:
Domain refers to the set of x values and range refers to the set of y values. Since x goes from 0 to 3, and does not exclude any values within those numbers, the first answer applies to that set.
