Answer:
Step-by-step explanation:
-8( - 20+ (-4)2) = 32
-8(-20 + 16) = 32
-8(-4) = 32
32 = 32
3√24= 3√2^2*6 = 3*2√6 = 6√6
2√384= 2√8^2*6 = 2*8√6 = 16√6
√96= √4^2*6 = 4√6
6√6 -16√6- 4√6 = -14√6
Final answer: -14√6
Answer: Ana will hit the water after 3 seconds.
Step-by-step explanation:
The exercise gives you the following function which models Anna's height above the water (in meters) after diving "x" seconds:

You can rewrite the function with
:

In order to calculate the number of seconds Ana will hit the water after diving, the procedure is:
- Substitute
into the function:

- Solve for "x".
By the Zero Product Property, you know that if
, then
or
.
Then you get:

- Choose the positive value (
)
Then, Ana will hit the water after 3 seconds.
Ok so which intercept? y or x
Answer:
-8/5
Step-by-step explanation:
The thing that makes lines different from other kinds of curves is their <em>constant rate of change</em>. We call this rate of change <em>slope</em>, and you usually see it represented with the letter <em>m</em>. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.
We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate <em>increases </em>by 5, while our y-coordinate <em>decreases </em>by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as
m = -8/5
