Answer:
AD = 6.76 inches
Step-by-step explanation:
Taking the triangle ABC:
tan 45° = AB/BC
1 = AB/BC
AB = BC = 16 in
Taking the triangle DBC:
tan 30° = DB/BC
DB = BC * tan 30°
DB = 16 * tan 30°
DB = 9.24 in
Given that AD + DB = AB, then
AD = AB - DB
AD = 16 - 9.24 = 6.76 inches
Answer:
x = 4
y = 3
Step-by-step explanation:
2x - 3(x - 1) = -1
2x - 3x + 3 = -1
-x + 3 = -1
- 3 - 3
(-1) -x = -4 (-1)
x = 4
y = 4 - 1
y = 3
An= -16 + (n-1)7
an= -16 + 7n - 7
an=7n -23
When the rate of change is 7
{a1 = 16, a2=-9, so the rate of rate of change is 7}
