Answer:
a2 = 12
a3 = 36
Step-by-step explanation:
Terms of a geometric sequence have a common ratio. If we call that ratio r, then we have ...
a2 = 4r
a3 = (a2)r = 4r^2
108 = (a3)r = 4r^3
27 = r^3 . . . . . . . . . . . divide by 4
3 = r . . . . . . . . . . cube root
__
a2 = 4(3) = 12
a3 = 12(3) = 36
Answer:
44ft
Step-by-step explanation:
The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.
Answer:
A
Step-by-step explanation:
The square root of 5 is irrational because it cannot be expressed as a fraction.
Meanwhile, all 3 other answer choices are not irrational because they can be put into fraction form.
Answer:
1/3 is your answer
Step-by-step explanation:
Note that in the slope intercept form, the equation looks like: y = mx + b
Isolate the y. First, subtract 3x from both sides
3x (-3x) - 9y = (-3x) + 4
-9y = -3x + 4
Next, to fully isolate the y, divide - 9 from both siedes
(-9y)/(-9) = (-3x + 4)/(-9)
y = (-3x + 4)/-9
Simplify
y = (1/3)x - 4/9
You're slope of the line (m in y = mx + b) is 1/3
