Given that the area of right triangle is 24 square centimeter, what is the functional relationship between Y and X? Combined with the actual situation, write out the value range of independent variable x The relation is y = 48 / X. I know. What's the range of values? X > 0? And when x=_____ The right triangle is an isosceles right triangle.

x. Y is the length of two right angles?
Combining with the actual situation, the value range of X is x > 0
When the triangle is isosceles right triangle, x = y = 48 / X
x^2=48
x=4√3

In an isosceles right triangle, the longest side is 10 cm long. How many square centimeters is the area of this triangle?

A: the area of this isosceles right triangle is 25 square centimeters

When the straight side of a right triangle is 10 and the square side is 10, e and D coincide. EFG moves at the speed of 2. The function of the overlapping area y and the time x is

Because of the triangle EBC, EB ^ 2 = EC ^ 2 + BC ^ 2
So 16 = x ^ 2 + (4x) ^ 2
16=17x^2
x^2=16/17
It is easy to get that triangle FDE is similar to triangle ECB, so if De is 3x, BC is 4x
So EC is X. using Pythagorean theorem, we get x ^ 2 = 16 / 17
Because area = (4x) ^ 2 = 256 / 17

The hypotenuse of a right triangle is 12 cm, the perimeter is 30 cm, and the area is calculated

Answer: 36. Let two right angle sides be x and Y respectively. The equations are: x square + y square = 12 square; X + y + 12 = 30. The solution is: (1) x = 12, y = 6 (2) y = 30 (rounding) s = 1 / 2 * 6 * 12 = 36

Why is the cross-sectional area of the wire used to transmit the same amount of electricity at 220 V to 110 V with the same transmission loss twice as small
What's the relationship between current and conductor

The electric quantity is directly proportional to the current, the electric quantity is the same, that is, the current is the same, u = IR, so the wire resistance R2 of 220 V should be twice that of 110 V wire resistance R1, and R = PL / S (P is the resistivity, l is the wire length, s is the wire cross-sectional area). Therefore, when other factors are the same, the cross-sectional area of 220 V wire is half that of 110 V wire

When the voltage of transmission line is high and the cross-sectional area of conductor is large, the voltage loss caused by reactance is larger than that caused by resistance

In fact, the voltage drop of high-voltage transmission line is very small, while the voltage drop of low-voltage transmission line is very large. For a specific line (with fixed resistance), the voltage drop of high-voltage transmission line is 5V, and that of low-voltage transmission line is 50V. In this way, the loss of high-voltage line is small, and that of low-voltage line is large
