Answer:
They will be at the same position after 2 hours.
Step-by-step explanation:
Here, it should be asked the time it will take for Anita to catch Brad.
Anita began riding at start of the path and is riding at rate of 18 mile per hour.
This means that, after t hours, her position will be given by:

Brad begin from a sport 10 mile ahead of her and I riding at rate of 13 mile per hour
This means that, after t hours, his position will be given by:

After how much time will they be at the same position?
This is t for which:

So




They will be at the same position after 2 hours.
|x| + 9 ≤ <span>7
</span>
Add -9 from each side
<span><span>|x| + 9 </span>+ <span>−9 </span></span>≤ <span>7 + <span>−9
</span></span><span>|x| </span>≤ <span>−<span>2
</span></span>
Now solve the absolute value
(You can't because the absolute value would end up less than 0 and it's not possible for that to happen)
No Solution
we have
which is a cubic function.
and
.
from f(x) and g(x) we know that both are cubic and g(x) has shrink of 1 and up by 4 units in x axis .
Answer:
Four unique planes
Step-by-step explanation:
Given that the points are non co-planar, triangular planes can be formed by the joining of three points
The points will therefore appear to be at the corners of a triangular pyramid or tetrahedron such that together the four points will form a three dimensional figure bounded by triangular planes
The number of triangular planes that can therefore be formed is given by the combination of four objects taking three at a time as follows;
₄C₃ = 4!/(3!×(4-3)! = 4
Which gives four possible unique planes.
The answer is i don’t know or I don’t care and what are we trying to find
