3.125 as a fraction is 25/8
Answer:
96
Step-by-step explanation:
Answer:
The zeros of the given polynomial function are
2,2,
Step-by-step explanation:
Given polynomial is 
To find the zeros equate the given polynomial to zero
ie., P(x)=0

By using synthetic division we can solve the polynomial:
2_| 1 -4 -1 20 -20
0 2 -4 -10 20
_____________________
1 -2 -5 10 |_0
Therefore x-2=0
x=2 is a zero of P(x)
Now we can write the cubic equation as below:

Again using synthetic division
2_| 1 -2 -5 10
0 2 0 -10
______________
1 0 -5 |_0
Therefore x-2=0
x=2 is also a zero of P(x).
Now we have 


is a zero of P(x)
Therefore the zeros are 2,2,

Step-by-step explanation:

Write in exponential form
Using the law of logarithm which says if
then

By comparison;
A = 16; b = 2 and x = 4
The expression
becomes


Write in exponential form
Applying the same law as used in (1) above;
A = 2; b = 16 and 
The expression
becomes

Write in logarithm form
Using the law of logarithm which says if
then

By comparison;
b = 2; x = z and A = y
The expression
becomes

So there are 2 dogs to every 3 cats (put into words)
in order to reach 15 total multiply both 2 and 3 by 3
2x3 = 6
3x3 = 9
so there are 6 dogs and 9 cats
