Answer: Choice B) pi/4 < x < 3pi/4
Graph the function using a graphing calculator. I used desmos which is a free online tool. The graph is shown below as the red curve. The blue region represents the region in which the red curve is going downhill as you read from left to right on the interval from x = pi/4 to x = 3pi/4.
Answer:
40
Step-by-step explanation:
Let number of stickers Sophia has be "x" and number of stickers Ethan has be "y"
Now,
Sophia has 3 for every 2 ethan has, that means
3x = 2y
When sophia gives 16, she will have:
3x - 16
Ethan, after getting 16, will have:
2y + 16
This trade will make Ethan to have TWICE, so we can write:
2(3x-16) = 2y + 16
Now, the 1st equation can be written as:
3x = 2y
x = 2y/3
Now replacing this into 2nd, we solve for y:
So altogether they have:
24+16=40
Answer:
72yd2
Step-by-step explanation:
making figure into 2
1st figure
= 6×5
= 30yd^2
2nd figure
= 14×3
= 42yd^2
Area of the full figure
= (30+42)yd^2
= 72yd^2
