There are 6 combinations:
TWB TBW BTW BWT WBT WTB
I can solve it?
take away 11 from both sides to make..
4x = 4
simplified (4 ÷ 4) to make x=1
Answer:
the Area is approximately 1
Step-by-step explanation:
Since
y=x^3
the area under a curve can be approximated to rectangles of width Δx and length y , then
Area = Sum of rectangles of width x and length = ∑ y *Δx
taking the width Δx=1 for each rectangle
Area = Sum of rectangles of width x and length= ∑ y = ∑ x^3
from x=0 to x=1 , there is only one rectangle of width Δx=1 , then
since ∑ x^3 from x=0 to x=n is n(n+1)/2]^2
Area = ∑ x^3 from x=0 to x=1 = 1(1+1)/2]^2 = 1
Note:
- The actual value of the area is calculated through the integral
Area= ∫ y dx = ∫ x^3 dx from x=0 to x=1 = 1⁴/4 = 1/4
Answer:
B.
Step-by-step explanation:
Let's call x the number of pens and y the number of notebooks that Monique can buy.
If each pen costs $2 and each notebook costs $3, so she is going to spend 2*x on pens and she is going to spend 3*y on notebooks.
Additionally, she is going to spend a maximum of $36. so:
2x + 3y 36
It means that the line that separated the region is:
2x + 3y = 36
This is the same that a line that passes for the points (0,12) and (18,0) or the line of the region B
