Answer:
A
Step-by-step explanation:
theare are 5 part from 0 to -1
since, the value from 0 to -1 is -1 then if we break it to 5 part, each part has value of -1/5
so, to be -4/5, -1/5 must be multiplied by 4, so we need to go to the 4th part from 0, so it A

Answer:
It's in the air for about 2 seconds (A), maximum height was about 17 feet, and yes you win the price since 17> 15.

Answer:
B
Step-by-step explanation:
First calculate BD using sine ratio in Δ BCD and the exact value
sin60° =
, thus
sin60° =
=
=
=
( cross- multiply )
2BD = 12
( divide both sides by 2 )
BD = 6
-----------------------------------------------------------
Calculate AD using the tangent ratio in Δ ABD and the exact value
tan30° =
, thus
tan30° =
=
=
=
( cross- multiply )
AD = 6
( divide both sides by
)
AD = 6 → B
1/x+1/a=1/a
minus 1/a from both sides
1/x=0
false
let's try a differnt way
1/x+1/a=1/a
times both sides by xa
a+x=x
minus x from both sides
a=0
???
1/0 is undefined
this creates problems
