For this case, the first thing you should do is know that the measurement of a television is given by the diagonal of the television.
Therefore, to find the value of x, we use the Pythagorean theorem.
We have then:
Rewriting we have:
Then the dimensions are given by:
Answer:
the dimensions of the screen are: 33.6* 25.2
Answer:
Option 3
Step-by-step explanation:
we are given the graph of a parabola
with vertex at (0,-1) and symmetrical about y axis and also open up.
Hence the equation of the graph would be transformation of
by a vertical shift of 1 unit down.
So new equation after transformation would be
Or
Hence option 3 is right choice.
Verify:
Put Solving the equation we get
In the graph x intercepts are the same as -1 and 1
Hence our answer is right.
