Answer:
r = -4/5
Step-by-step explanation:
Divide both sides by 15 so you have r
-12/15 simplify (both by 3)
-4/5
Answer:
8-d , 9-c ,and i cant see 10
Step-by-step explanation:
this is just what i know off of what i've learned
0.008 i think this is the answer
A given term in a PG =a₁rⁿ⁻¹
Let' calculate the 1st term a₁, knowing a term & the common factor/ratio
a₄ = 1/2 so 1/2 = a₁(1/2)³
1/2 = a₁/8 and a₁ = 4
Now calculate a₉ =a₁.r⁸
a₉ = 4.(1/2)⁸ and a₉ = 1/64
F(x) = -2(x - 3)^2 + 2 = -2(x^2 - 6x + 9) + 2 = -2x^2 + 12x - 18 + 2 = -2x^2 + 12x - 16
f(x) = -2x^2 + 12x - 16
