Find common ratio
1 times -3=-3
-3 times -3=9
an=a1(r^(n-1))
a1=first term
r=common ratio
n=which term
an=1(-3)^(n-1)
9th term
n=9
an=1(-3)^(9-1)
an=1(-3)^(8)
an=1(6561)
an=6561
answer is D
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h. k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 6, - 1), thus
y = a(x + 6)² - 1
To find a substitute one of the roots into the equation
Using (- 3, 0), then
0 = a(- 3 +6)² - 1
0 = 9a - 1 ( add 1 to both sides )
1 = 9a ( divide both sides by 9 )
a = , thus
y = (x + 6)² - 1 ← in vertex form
Expand factor and simplify
y = (x² + 12x + 36) - 1 ← distribute
y = x² + x + 4 - 1
= x² + x + 3 ← in standard form
Answer:
It is also 124 degrees.
Step-by-step explanation:
Well, if a = -1 and b = 4 then when we plug in the values of a and b into the expression we get:
.
Then simplify it:
.
The answer is A.
