Ok so its 8 `1&8 2&7 3&6 4&5 and then all of those numbers reversed
18 27 36 45 and 81 72 63 54
Step-by-step explanation:
the angle CDB is the supplementary angle to 9x+10 (angle ADC).
that means they stand together for 180°. as all angles around a single point on one side of a line are together always 180°.
and then, the sum of all angles in a triangle is always 180°.
so,
CDB + (4x + 10) + 50 = 180
CDB = 180 - (9x + 10) = 180 - 9x - 19 = 170 - 9x
therefore,
(170 - 9x) + (4x + 10) + 50 = 180
170 - 9x + 4x + 10 + 50 = 180
-5x = -50
5x = 50
x = 10
angle CDB = 170 - 9x = 170 - 90 = 80°
Answer:
Other root is -95i
Step-by-step explanation:
Here, Nature of roots of f(x) is imaginary roots.
Therefore, Roots are conjugate of each other.
Conjugate of x + yi is x - yi.
we get conjugate of 95i as -95i
Verification shows....
(x-95)(x+95i)=0
this, roots are -95i and 95i
From the graph at x = 0, y = 0
Check1:
y = cosx
0 = cos(0)
0 = 1
therefore, this is not the function
Check2:
y = sinx
0 = sin(0)
0 = 0
therefore, this is the function
Conclusion:
the function in the graph is y = sinx
Ok so first I am assuming you ment 2 sevenths so 12 divided by 2 sevenths is 42. so the father is currently 42. so when she was 10 he was 40. since 10 is 4 times 40 that is the age we need. so 42 minus 40 is 2. therefore the answer is 2.
