Answer: X = 2.75
Step-by-step explanation: 2x2 = 4x-7
4 = 4x-7
11 = 4x
11 \ 4
X = 2.75
Answer:30° - 3d ≤ 20°
Step-by-step explanation:
We have to represent the rate of temperature decrease in degrees .We will represent this by "d" which stands for degree.
According to the question , temperature decreased at a constant rate in the next three days
Therefore , the total decreasing in three days = 3d degree i.e 3 *d=3d
Temperature on Monday = 30°
Then the temperature on Thursday is this = 30° - 3d
Since, The swimming pool is open when the high temperature is higher than 20°=≤20
= 30° - 3d ≤ 20°
This is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, "d"from Monday to Thursday.

Answer:
A = 0.859
Step-by-step explanation:
We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).
At y = 0, let's find x;
0 = xe^(x²)
Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.
So our upper band is x = 1
Thus,lets find the area;
A = ∫xe(x²) dx between 1 and 0
A = (e^(x²))/2 between 1 and 0
A = ((e¹)/2) - (e^(0))/2)
A = 1.359 - 0.5
A = 0.859
