Answer:
Step-by-step explanation:
In a geometric sequence, consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1r^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the given sequence,
a1 = - 5
r = 15/- 5 = - 3
Therefore, the explicit rule for this sequence is
an = - 5(- 3)^n - 1
Answer: Table D
Step-by-step explanation:
The coefficient of x^2 is -9, the coefficient of x is 7, and the constant is 0, so we know a = -9, b = 7, c = 0.
- This eliminates tables A, B, and C.
Thus, table D is the answer.
Answer:
40 respondents
Step-by-step explanation:
Percentage of respondents who watch TV for one hour each day = 75%
Number of respondents who watch TV for one hour each day = 30
Let 
denotes total of respondents who watch TV for one hour each day.
Therefore,
Answer:
m= 70
s= 40
a= 110
d= 40
Step-by-step explanation:
Angle M is equal to 70 because it is an isoleases triangle.
The 3 sides of a triangle is equal yo 180. So if angle m is 70, then 70+70 is 140. 180-140 is 40. This makes angle s= 40.
Now we have to find angle a. Angle a and 70 make a straight line. So the line is 180. 180-70 is 110. Angle a is equal to 110.
Now we have to find angle d. As I said before All the angles of a triangle equal to 180. 30+110= 140 now 180 - 140= 40. This makes angle d= 40.
