PLEASE HELP! GRAPHING The function h(t) = −5t2 + 15t shown in the graph models the supporting structure of a bridge:

graph of parabola starting at zero comma zero, rising from the left to about one and one half comma 11, and falling to the right, ending at 3 comma zero

What is the domain of h(t)?

All real numbers
0 ≤ x ≤ 11
0 ≤ x ≤ 3
x ≥ 0

Please right answers only

at least i think its

step-by-step explanation:

their are no angles. sorry cant .

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
