IF your equation is this: h(t)= -16t^2 + 27t + 7, then you set it equal to 17 and solve for t. What this does is tells you the times (t) when the ball is exactly 17 feet off the ground. Because this is a parabola, the ball will go up past the 17 foot mark, then pass it again on the way back down. This happens at .55 seconds (going up), and 1.13 seconds (coming down).
Answer:
3.60m
Step-by-step explanation:
In backwaters of Kerala, a boatman was throwing a boat with a long pole which has a length of 4.80m
The boatman put the pole into the water vertically, the part of the pole that was seen above the water level is 0.25m
The first step is to calculate the length of the pole that is seen above the water level
= 4.80 × 0.25
= 1.20m
Therefore the depth of the water at that point can be calculated as follows
=4.80m - 1.20m
= 3.60m
Hence the depth of the water at that point is 3.60m
A = p(1 + r)^t
A = 6000(1 + .07)^8
A = 6000(1.07)^8
A = 10,309.12
The amount in the account after 8 years is 10,309.12, subtract the amount of principle, and you will get the amount of interest earned.
10,309.12 - 6,000 = $4,309.12
Interest $ 4,309.12
Answer:
Step-by-step explanation:
water = 1 litre = 1000 ml
water : sucrose : saline = 1000 : 199 : 271
Answer:
It has 1 term and a degree of 4.
Step-by-step explanation:
3j⁴k-2jk³+jk³-2j⁴k+jk³
= 3j⁴k-2j⁴k-2jk³+jk³+jk³
= j⁴k
So, in this expression, there is 1 term, and it has a degree of 4.
