Step-by-step explanation:
When t = 2,
h(2) = 8 + 40.8(2) - 16(2)² = 8 + 81.6 - 64 = 25.6
Therefore the height after 2 sec is 25.6.
Answer: y = 2
Step-by-step explanation:
we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:
since x=2y+1,
we can say that:
(2y+1)+2y=9
then we solve this equation,
first we expand the brackets- 2y+1+2y=9,
then we combine like terms- 4y+1=9
then we take 1 away from both sides- 4y=8
then we divided both sides by 4
y=2
Hope this helps xx
