Answer:
x^2-5xy+4y^2
Step-by-step explanation:
In the equation we see only 1 example of like terms, 2xy-7xy=-5xy
So the simplified equation is
x^2-5xy+4y^2
Answer:
5.2 maybe I don't now and if wrong
Answer:
8 x 8 x 8 x 8 = 4096
Step-by-step explanation:
Its an exponent which means you multiply 8 by itself 4 times to get 4096.
Answer:
-6
Step-by-step explanation:
The answer is a= - 6
The endpoint is (-6,6)
The want the value of x and its equal - 6
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).
