Answer:
Step-by-step explanation:
The n th term of a geometric sequence is
= a 
where a is the first term and r the common ratio, hence
= 4 × 
= 4 × 
=
The answer is x equals 62
Answer:
Step-by-step explanation:
Add like terms.
Answer/Step-by-step explanation:
#8. Using the geometric mean theorem formula, h = √xy, where,
h = x
x = 4 and y = 16
Plug in the values
x = √(4*16)
x = 8
#9. Using the geometric mean formula, h = √xy, where,
h = y
x = 5 and y = 8
Plug in the values into the formula:
y = √(5*8)
y = √40
y = 6.3 (nearest tenth)
#10. Using the geometric mean formula, h = √xy, where,
h = 18
x = 12 and y = y = ???
Plug in the values into the formula:
18 = √(12*y)
Square both sides
18² = 12y
324 = 12y
Divide both sides by 12
27 = y
y = 27
Answer:
She would collect $27.
Step-by-step explanation:
A dozen means that it is a set of twelve items, so in order to find the amount of cupcakes she sold, you have to multiply 12 for the number of dozens she baked which was 3:
12*3=36
Now that you know the number of cupcakes she sold, you have to multiply this for the price of each cupcake:
36*$0.75= $27
According to this, the answer is that she would collect $27.
