Answer:
See explanation
Step-by-step explanation:
To determine whether each of these functions is , we apply these theorems:
- A polynomial is always O(the term containing the highest power of n)
- Any O(x) function is always .
(a)Given the function: f(x)=100x+1000
The highest power of n is 1.
Therefore f(x) is O(x).
Since any O(x) function is always , 100x+1000 is .
The highest power of n is 2.
Therefore the function is .
CT=90°
BTA=90°
x=29
CT=37
TA=20
CA=57
Step-by-step explanation:
they say BT is an altitude ( or height) . Altitudes are perpendicular meaning that:
BTC =90°
BTA=90°
Therefore:
(3x+3)°=90°
3x=90-3
3x=87°
x=29
CT:
x+8
=29+8
=37
TA:
x-9
=29-9
=20
CA:
=CT+TA
=37+20
=57
13x + 7(-3x - 1) = -62
13x -21x -7 = -62
62-7 = 21x-13x
8x = 55
x = 55/8
So, Your Correct Answer would be 55/8
Hope this helps!
-0.4x=2.5 divide both sides by -0.4
x=-6.25
