Please help i have no clue what to do

b=3

Step-by-step explanation:

Pythagorean theorem

a²+b²=c²

use simple algebra to get the equation to say

a²-c²=-b² by subtracting b² on both sides and c² on both sides

plug in you numbers

4²-5²=b²

do the math

16-25=-9

square root it

b=√-9

b=3

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
