Solving 6x^2-24x-54 with quadratic formula

Mathematics
1 answer:
RoseWind [281]3 years ago

Answer:

x = 5.61 or -1.61

Step-by-step explanation:

x = \frac{ - b +  -  \sqrt{ {b}^{2} - 4ac } }{2a}

6x² - 24x - 54 = 0

6(x² - 4x - 9) = 0

x = [4+-√(4²)-4(1)(-9)]/2(1)

= (4+√52)/2

= 5.61

= (4-√52)/2

= -1.61

Between which pair of numbers is the exact product of 379 and 8?
AnnZ [28]
The product of 379 and 8 is 3,032.

It's between (any number less than 3,032) and (any number greater than 3,032).

I guess if this is an <em>estimation </em>exercise, you could say that it's between
(8 x 300) and (8 x 400), or 2,400 and 3,200.

The range of a function is the set of numbers used as y-coordinates.

Let's look at the y-coordinates of the points in the graph.
There are points in the graph with all y-coordinates greater than -3.
There are points in the graph with all y-coordinates less then -3.
At exactly -3, there is no point on the graph with that y-coordinate.
We expect the graph to behave as it is shown above 7 and below -7, so the only value excluded from the y-coordinates is -3.

Answer: B. All real numbers except -3
