Answer:
Step-by-step explanation:
Let's first put that polynomial in standard form by descending powers of t:
If we are looking for the times where the rocket is at a height of 26 m, we sub in a 26 for h(t) and factor to solve for t. First we get all the terms on one side of the equals sign and set it equal to zero.
That is a second degree polynomial so you can factor it however you are most comfortable to get the values of t are:
t = .51 sec and t = 10.29 sec
Since this is a polynomial, there will be 2 values of t for this time with y being the height and x being the time. The parabola is symmetrical about the vertex so there are 2 values of t (or x) that equal height (or y).
2.75a=19.25
19.25/2.75
a = 7
- So basically what I did was convert 2 3/4 and 19 1/4 into decimals. From there I divided 2 3/4 (2.75) by 19 1/4 (19.25) and I got 28.
- The numbers in parenthesis is the numbers in decimals.
- I hope that helps!!!!!
Answer:
$5,593.60
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 2.25% into a decimal:
2.25% -> -> 0.0225
Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:
<u>The balance will be $5,593.60</u>
