Given:
second term = 18
fifth term = 144
The nth term of a geometric sequence is:
Hence, we have:
Divide the expression for the fifth term by the expression for the second term:
Substituting the value of r into any of the expression:
Hence, the explicit rule for the sequence is:

Answer:
A ≈ 2 ft²
Step-by-step explanation:
The area (A) of a triangle using Heron's formula is
A = 
where s is the semiperimeter and a, b , c the sides of the triangle.
s = 
= 
= 
= 4.5
Then
A = 
= 
= 
≈ 1.9843...
= 2 ft² ( to the nearest square foot )
Answer:
<h2>
56% </h2>
Step-by-step explanation:
Haley practiced her free throws at the basket ball court and shot 25 times
She made 11 of her shots.
find: What percent of her shots did she NOT make?
<u>11 shots made</u> = 44%
25 shots
100% - 44% = 56%
therefore, 56% of her shot did NOT make it.
To solve this, you cross multiply, then divide. In this case, we multiply 4 and 2, then divide by 3.
4 x 2 = 8
8 / 3 = 2.66
So, x is 2.66
