Step-by-step explanation:
x = 1.21212121.....
100x = 121.21212121...
Therefore 99x = 120 and x = 120/99 = 40/33.
if the horizontal lines are all parallel, then yes, as long as the angles are on the same side. If the horizontal lines are parallel but the angles are on opposite sides, then no. If the horizontal lines are not parallel, then it would require more work to figure it out
The sum of all three angles in any triangle is always 180 degrees. So in obtuse triangle there is only one obtuse angle (more than 90 degrees). If we have for example an obtuse angle of 91 degrees, then two other angles have to fit in 89 degrees which makes it impossible for any of them to be obtuse.
I only found b I’m still working on a anyways.
Answer:
339
Explain: 339+39= 378 you can divide 378 by 9 which is 42, 42 subtracted by 3 is 39
Answer:
(Missing part of the question is attached)
Estimates are too large.
Step-by-step explanation:
Suppose the only information we know about the function is:
where the graph of its derivative is shown in the attachment
<h3>(a)</h3>
If the function 
is differentiable at point 
, the tangent line to the graph of 
at 1 is given by the equation:
So we call the linear function:
We know the as it is given in the question, and 
from the graph attached. Substitute in the equation of 
.
<h3>(b)</h3>
At x=1, 
is positive but it is decreasing. However. if we draw the tangent lines, we see that the tangent lines are becoming less steeper, so the tangent lines lie above the curve . Thus, The estimates are too large.
