A. The x-coordinate is negative, and the y-coordinate is negative.
B. The x-coordinate is positive, and the y-coordinate is positive.
C. The x-coordinate is positive, and the y-coordinate is negative.
O D. The x-coordinate is negative, and the y-coordinate is positive.
Please hurry
The correct answer is B. The x-coordinate is positive, and the y-coordinate is positive, is true about points located in quadrant I in the coordinate plane.
We know that,
Quadrant I is the top-right quadrant of the Cartesian coordinate plane.
In this quadrant, both the x-coordinate and the y-coordinate are positive.
This means that the values of both the horizontal (x) and vertical (y) distances from the origin are increasing as you move to the right and upward from the origin.
Option A is incorrect because it states that both the x-coordinate and y-coordinate are negative, which is not true for points in Quadrant I.
Option C is incorrect because it states that the x-coordinate is positive and the y-coordinate is negative, which is not true for points in Quadrant I.
Option D is incorrect because it states that the x-coordinate is negative and the y-coordinate is positive, which is not true for points in Quadrant I.
Quadrant I is characterized by positive values for both the x-coordinate and the y-coordinate,
so the correct answer is Option B.

Answer:
B
Step-by-step explanation:
In Quadrant I, both the x– and y-coordinates are positive; in Quadrant II, the x-coordinate is negative, but the y-coordinate is positive; in Quadrant III both are negative; and in Quadrant IV, x is positive but y is negative.

Answer:
The correct answer is x = 32.
Step-by-step explanation:
To solve this problem, we must remember the concept of supplementary angles. Two angles that are supplementary together make an angle of 180 degrees (a straight line).
In this case, we can see that inside the triangle, we will have an angle of 80 degrees. We know this because the angle at the top of the triangle is supplementary with the angle measuring 100 degrees, so its measure should be 180-100 = 80 degrees.
On the lower right hand of the triangle, a similar rationale can be applied. The angle inside of the triangle must measure 68 degrees, since it is supplementary to an angle measuring 112 degrees, and 180-112=68.
Finally, to solve this problem, we must remember that the sum of the three interior angles of a triangle should be 180 degrees. This lets us set up the following equation:
80+68+x = 180
Now, we can solve this equation. Our first step is to simplify the left side of the equation by adding together the constant terms.
148 + x = 180
Next, we should subtract 148 from both sides of the equation.
x = 180-148
x = 32
Therefore, the correct answer is x = 32 degrees.
Hope this helps!

Answer:
An interesting experiment is given. We need to address various questions based on our knowledge of calculus.
Step 2
Part (a)
Time taken for the radius to grow to 2 cm = t1 = r/0.5 = 2/0.5 = 4 hours
Time taken for the radius to become 0 = t2 and the same can be obtained by solving:
r = 2 - √t2 = 0
Hence, t2 = 22 = 4 hours
Hence, the time duration of the entire experiment (from the introduction of the bacteria until its disappearance) = t1 + t2 = 4 + 4 = 8 hours
Step 3
Part (b)
r(t) = 0.5t for 0 ≤ t ≤ 4
and
r(t) = 2 - √(t - 4) for t > 2
