This is one of the special right triangles known as a 30, 60, 90 triangle. (Characterized by its angles)

In these triangles, the shortest leg is HALF the length of the hypotenuse.

The longest leg is (√3) times the length of the short leg.

Therefore, the shortest leg is 20, and the longest leg is 20(√3)

FINAL ANSWER:

SHORT LEG: 20 units

LONG LEG: 20√3 units

The length and width of a rectangular room are measured to be 3.955±0.005m. Calculate the area of the room and its uncertainty i
Margarita [4]

Answer:

The area of the room and its uncertainty in square meters is:

15.642±0.040 m^2

Step-by-step explanation:

We know the area of a rectangular room is the multiplication of the length and width:

Area= 3.955m*3.955m\\Area= 15.642 m^2

Now we need to know the uncertainty, the uncertainty of a multiplication is:

\frac{δ_a}{|Area|} =\frac{δ_L}{|L|}+\frac{δ_W}{|W|} (1)

δ_A: Area uncertainty

δ_L: Length uncertainty

δ_W: Width uncertainty

A: Area of the room

L: Length

W: Width

Clearing the uncertainty of the area:

δ_A=(\frac{δ_x}{|x|}+\frac{δ_y}{|y|})*Area (2)

δ_A=(\frac{0.005}{|3.955|}+\frac{0.005}{|3.955|})*15.642 m^2

δ_A= 0.040 m^2

The area of the room and its uncertainty in square meters is:

15.642±0.040 m^2

lesya692 [45]

Answer:

29

Step-by-step explanation:

Given the function f(x) = x/10x-3, if x = 0.30103;

substituting the value of x into the function;

f(0.30103) = 0.30103/10(0.30103) - 3

f(0.30103) = 0.30103/(3.0103 - 3)

f(0.30103) = 0.30103/0.0103

f(0.30103) = 29.226

f(0.30103) = 29 (to nearest whole number).
