Answer: C - the fourth month
Step-by-step explanation: If it doubles every month, then at 6 months there should be 32 times the original affected area. 1/8 of 32 is 4.
Algebraic expression always have a percent the x-ray and white rate that you have to multiply and flip around so I could get a total answer
Answer:
a) Explicit Formula : aₙ = 3. (-3)ⁿ⁻¹
b) Fifth term : a₅ = 243
Step-by-step explanation:
This sequence above is the Geometric sequence. The Geometric sequence is calculated using the formula
aₙ= a1.rⁿ⁻¹
where a1 = first term
r = common ratio
n = number of terms
From the above question, we are given
a1= 3, r=-3 and asked to find the explicit formula.
The explicit formula using the geometric sequence formula =
aₙ = 3. (-3)ⁿ⁻¹
b) The fifth term in the sequence is calculated as
aₙ = 3. (-3)ⁿ⁻¹
Where n = 5
a₅ = 3.(-3)⁵⁻¹
a₅ = 3.(-3)⁴
a₅= 243
Answer: (x+5)(x-5)
Step-by-step explanation:
f(x)=X²-25 = (x+5)(x-5)
Answer:
16022 square foot
Step-by-step explanation:
The world's largest cookie was baked in North Carolina in 2003. Its diameter was 100 feet and it contained about 6,000 pounds of chocolate chips! If the cookie was a cylinder 1 foot tall, and you wanted to cover it with icing, how many square inches would you have to ice? Use 3.14 for .
We find the surface area of the cylinder
= 2πr(r + h)
r = Diameter /2 = 100 feet/2
r = 50 feet
h = 1 feet
Hence
2 × 3.14 × 50(50 + 1)
= 16022.122533 square foot
= 16022 square foot
