Answer:
7020
Step-by-step explanation:
The letter could be any 1 of the 26 and it could be placed in any 1 of 3 places so this makes 26*3 = 78 possibilities.
For each of these there is any one of permutations of 2 digits from 10
= 10P2 = 10! / 8! = 10*9 = 90.
So the answer is 78 * 90 = 7020.
Note I am assuming that the 2 digits picked are different - no duplicates.
please mark me brainliest!
Given that
attains a maximum at
, it follows that
at that same point. So integrating once gives
and so the first derivative is
.
Integrating again, you get
You know that this curve passes through the point (2, -1), which means when
, you have
:
and so
Answer:
slope is -2/5, y intercept is (0,5)
Step-by-step explanation:
The slope is the number in front of the x, or how steep the line is on the graph. In this case, it is -2/5.
The y intercept happens when x = 0, so if you make x = 0 in this equation, you find that you are left with y = 5. That gives you the point (0,5) as your y intercept.
Given :
∆GHI is an isosceles triangle with a vertex angle H.
m∠H=80°
To Find :
The m∠I.
Solution :
Since, H is the vertex angle.
So, m∠I = m∠G = x
We know, by angle sum property of triangle :
m∠I + m∠G + m∠H = 180°
2x + 80° = 180°
x = 50°
Therefore, m∠I = 50° .
