Answer:
r=8
Step-by-step explanation:
you divide 28 by 3 1/2 to get r=8
Answer:
Step-by-step explanation:
First, add two to both sides to get 
There are two ways to solve this from here
- Think about what power you would have to raise 9 to to get to 27.
= 3 and 
. So, multiplying the powers (because it is a power to a power) you get 
. This means that 
or x = . - Take the log of both sides.
This gives us 
Answer:
Domain is (-infinity,infinity)
Range is (-infinity,3)
Answer:
x=7/3
Step-by-step explanation:
8 ^ (x - 1 ) = 16
We need to rewrite 8 as 2^3 and 16 as 2^4
2^3 ^ (x - 1 ) = 2^4
We know that a^b^c = a^(b*c)
2^(3(x-1)) = 2^4
The bases are the same so the exponents are the same
3(x-1) = 4
Distribute
3x-3 = 4
Add 3 to each side
3x-3+3 = 4+3
3x = 7
Divide by 3
3x/3 = 7/3
x=7/3
The perimeter of the top of the basket is 20 in.

What is perimeter of square?</h3>
Perimeter of square is defined as addition the lengths of the square's four sides.
Diagonal = 6
Let, side of square = a
a²+a² = 6²
2a² = 36
a² = 18
a = 3√2
Perimeter of the square = 4 × side of square
Perimeter of the square = 4 × 3√2
Perimeter of the square = 12√2 ≈ 20 in
Hence, the perimeter of the top of the basket is 20 in.
