Answer:
x = 145°
Step-by-step explanation:
We know that y = 98°, so we can find ∠DBC:
180°-y = ∠DBC
180°-98° = 82°
We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.
∠DBC + z = x
82°+63° = x
x = 145°
Answer:
32
Step-by-step explanation:
Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3
Therefore, the coefficient of the squared expression is -3.
First, what letter can it be at the beginning?
English Alphabet has 26 letters, so we have 26 possibilities
26*
then it can be any of 10 digits
26*10=260
then any of the remaining 9 digits:
26*10*9
then any of the remaining 8 and 7 digits:
26*10*9*8*7=131040
so the solution is: 131040 possible combinations!
