sry if im wrong hope this helps
brainliest? please?
To do this you must plug in 1 and negative one for each x variable and each y. that solution is a point so the 1 must be tested for x and the -1 for y. do this and solve to find a and b so that it works in both equations!
Answer:
(2.5,10.5)
Step-by-step explanation:
Given that a ball is thrown verically upwards with an initial velocity. We know that the path is a trajectory as a parabola.
From graph we find that horizontal is in yards and vertical is in feet.
WE have to find the coordinates of A
When ball is thrown upward, acceleration due to gravity is -32 ft/s^2
Since height = s=+h0
we get h0 as initial height.
But without any calculation from the graph we find out these coordinates as
x coordinate = 2.5(since in the middle of 0 and 5)
y coordinate = 10.5(since in the middle of 9 and 12)
(2.5,10.5) is the coordinate of A
Answer:
Step-by-step explanation:
The formula you will want to use for this is one that allows a certain number of compoundings of the interest per year. This is a specific one for compounding continuously, and there is one for finding simple interest. Here is the one we want:
where A(t) is the amount in the account after the compounding occurs over the number of years specified, P is the initial amount in the account, r is the interest rate in decimal form, n is the number of times per year the compounding occurs, and t is the amount of time the money is in the account in years. For us:
P = 300,
r = .04,
n = 4 (quarterly means 4 times), and
t = 10
Filling in:
and
and
and
A(t) = 300(1.488863734) so
A(t) = $446.66 or $447
