Answer:
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
Step-by-step explanation:
length of board in feet = 3 ft
As
1 ft = 12 inches
So
Length of board in inch = 
= 36 inches
Let no of 4 inches length be = x
The equation become

Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
I don't see a table lol, link it and I'll solve it
Answer:
Part A:
The correct option is (7, 15)
Part B:
The false statements at: f(2)=1 and f(15)=100
Step-by-step explanation:
Answer:
x=(5+i*sqrt(35))/2, (5-i*sqrt(35))/2
Step-by-step explanation:
Use the quadratic formula with the following values.
a = 1
b = -5
c = 15
Substitute and simplify.
(5+-sqrt((-5)^2-4*(1*15)))/2*1
x = (5+-i*sqrt(35))/2
When you get a negative number inside the square root, remember that you can pull out i to make the number inside positive.
Numbers less than 1 have a negative exponent
Here there are 2 digits after decimal point so the answer is
5 * 10^-2
