Answer:
The third one
Step-by-step explanation:
1. Rational. It is non-terminating but repeating.
2. Irrational. It is non-terminating, non-repeating
3. Irrational. π is irrational
4. Rational. √49 is 7
5. Irrational. 22 is not a square.
a.This set of vectors are not basis for vector space for two-dimentional space R2 due to high number of vectors (3). It means three vector is two much to span 2-dimentional space.
b.This set of vectors are not basis for vector space for three-dimentional space R3 due to small number of vectors (2). It means two vector can't span three-dimentional space.
Answer:
New width of coup feet
New length of coup feet
Step-by-step explanation:
Width of chicken coup = feet
Length of chicken coup= feet
Area of the coup =
New area is double the current area which is =
is added to both length and width.
New width of coup = feet
New length of coup = feet
New area of coup can be written as =
So, we have
Using FOIL method to multiply.
Subtracting 280 both sides.
Rearranging terms, we have the quadratic equation to solve.
Using quadratic formula to find
Plugging in values.
Since is the length, so it cannot be negative. So
New width of coup = feet
New length of coup = feet
Answer:
12 feet
Step-by-step explanation:
Area of a Rectangle: l × w
84 ft² = l × 7 ft
Length = 84 ft² ÷ 7 ft = 12 feet
Hope this helps.
