The analytic formula of sinusoidal current I = 8sin (314T - π / 3) a
Maximum im = 8a,
Angular frequency ω = 2 π f = 314 radians / s,
Period T = 1 / F = 1 / 50 = 0.02 seconds,
Phase difference: does not exist,
Frequency f = 1 / T = 50 Hz,
Initial phase Φ = π / 3 = 180 / 3 = 60 & #

Sine current I = 100sin (314-60 degrees) A. find out its frequency, period, amplitude, effective value and initial phase

Frequency: 50 Hz
The period is 0.02s
The effective value is 70.7a
Amplitude 100A
Initial phase - 60 degrees

A, B and C all have deposits in the bank. B's deposits are 100 yuan less than two times of a's, and C's deposits are 300 yuan less than a's and B's
A's deposit is 2 / 5 of C's. how much is the total deposit of a, B and C? If it is an equation, please write down the steps of the equation clearly

Set C's deposit is x yuan,
x=(2*2/5x-100)+2/5x-300
x=2000
A's deposit is 800
B's deposit is 1500

Let the equation 2-sin2x = m (2 + sin2x) about X have a solution and find the value range of M

2-sin2x=2m+msin2x.
(m+1)sin2x=2-2m.
sin2x=(2-2m)/(m+1).
Because the value of sin2x is [- 1,1], the value of (2-2m) / (M + 1) is [- 1,1]
It is calculated that M is less than or equal to 3 and greater than or equal to 1 / 3

1.8 * [6 and 5 / 12 / 16 + 3 / 8 * (9-2 and 7 / 120] / 2 and 3 / 4
How to calculate this problem?
Write clearly
Because the formula is long

1.8 × [(77 / 12) / 16 + (3 / 8) × (9-247 / 120)] / (11 / 4) = 1.8 × [77 / (12 × 16) + (3 / 8) × (833 / 120)] / (11 / 4) = (1 and 4 / 5) × (77 / 192 + 833 / 320) × (4 / 11) = (9 / 5) × (385 / 960 + 2499 / 960) × (4 / 11) = (9 / 5) × (721 / 240) × (4 / 11) = 2163 / 1100 = 1 and 1063 / 1

Given that a is a 2 * 6 matrix and B is a 3 * 6 matrix, then the homogeneous linear equations AX = 0 and BX = 0 must have a common nonzero solution,

From the known R (a)

Party A and Party B cooperate in a batch of parts, which can be completed in 20 days. The work efficiency ratio of Party A and Party B is 5:4
How many parts can a and B complete each day?

The efficiency sum of a and B is 1 / 20
A: 1 / 20 * 5 / (5 + 4) = 1 / 36
B: 1 / 20 * 4 / (5 + 4) = 1 / 45

12.7x－8.4=5x－7.6

12.7x－8.4=5x－7.6
12.7x-5x=8.4-7.6
7.7x=0.8
x=8/77

The weight ratio of goods in warehouse A and warehouse B is 7:8. If 6 tons are transported from warehouse B to warehouse A, the goods in the two warehouses will be equal. How many tons of original goods are there in warehouse A and warehouse B?

(6 × 2) △ 87 + 8-77 + 8, = 12 △ 115, = 180 (tons); a: 180 × 77 + 8 = 84 (tons); B: 180 × 87 + 8 = 96 (tons); a: the original goods in warehouse A are 84 tons, and the original goods in warehouse B are 96 tons

7x 6 = 8 (X-6) 4 solution equation
Good uncles and aunts, brothers and sisters, I am a fifth grade student, this is my homework. Please help, thank you first!

7x + 6 = 8 (X-6) + 4, is that so?
7x + 6 = 8x-48 + 4, first remove the brackets (using the law of multiplication)
7x + 6-7x + 44 = 8x-44-7x + 44 plus - 7x + 44 on both sides
50=x
That is: x = 50
