Answer:
sqrt(360)
Step-by-step explanation:
sqrt(360)=sqrt(36*10)=sqrt(36)*sqrt(10)=6*sqrt(10)
Let x be the value of the third term.
Since it's a geometric sequence, then:
Third term/Second term = Fourth term/Third term
x/20 = 11.25/x
Cross multiplication:
x^2 = 225
x = 15
So since the ratio is constant, then it is
x/20 = 15/20 = 3/4
So the common ratio is 3/4 or 0.75.
Answer:
(-2,-4), (-1, -1), (0,2), (1,5)(2, 8)
Step-by-step explanation:
you plug x into the equation to get y
Answer:
A
Step-by-step explanation:
You switch the y and x and solve for y.
y = 2x + 5
becomes
x = 2y + 5
Subtract 5 on both sides.
x - 5 = 2y
Divide 2 on both sides.
(x - 5) / 2 = y
The answer to your question is the second option, 3(4a − 2) = (4a − 2) ⋅ 3
Hope this helps!
