Answer:
t = 54 seconds
Step-by-step explanation:
The equation that models the path of a rocket into the air is given by :
It is required to find the time after which the rocket will hit the ground. When it hits the ground, the height of the rocket will becomes zero. It means,
h(t) = 0
i.e.
It means after 54 seconds, the rocket will hit the ground.
Answer:
About 34 workers
Step-by-step explanation:
200/30 to find on average how many trees can be carved by one worker
The answer is 6.666, so just 6
Then 6*4=24 to figure out how many more trees can be carved by (4 more) workers
So, add 4 to 30 and about 224 trees can be carved.
8^2, 4^3, and 2^6 are 3 ways
A1. 12 i.e option D
A2. 3n-7 i.e option A
A3. -6n+20 i.e option D
A4. -70 i.e option C
Step-by-step explanation:
aₙ = a₁ + (n - 1) × d
aₙ = the nᵗʰ term in the sequence
a₁ = the first term in the sequence
d = the common difference between terms
Using the above formula to solve the first part, we have :
For the second part, we have :
For the third part, we have :
For the fourth part, we have :
