Using the given equation h=-t^2+8t solve.

Step-by-step explanation:

hello :

h(t) = -t²+8t

the highest point is the vertex of this prabola (-b/2a ; h(t) )

a= -1  and   b= 8     -b/2a = - (8)/2(-1) = 4

h(4) = -(4)²+8(4) = -16+32 = 16

first answer : 16

second answer : 4

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
