Answer:
Step-by-step explanation:
If the impedance is related to the voltage and the current by the formula V = IZ where;
V is the voltage
I is the current
Z is the impedance
Given
I = 0.4+3i
V = 0.3-2i
Voltage V = (0.4+3i)(0.3-2i)
V = 0.4(0.3)-0.8i+0.9i-6i²
V = 0.12+0.1i -6i²
Since i² = -1
V = 0.12+0.1i-6(-1)
V = 0.12+0.1i+6
V = 6.12+0.1i.
Hence the impedance is 6.12+0.1i
So first, you will do $10.05x2
Then add the product of that to $18.95
Next you will get the sum of that and multiply it by 7%
Finally you will round to the nearest hundredth (0.01)
Answer:
BE = 49 cm
Step-by-step explanation:
Use Pythagorean theorem
(hypotenuse)² = (base)² + (leg)²
ΔDEF,
DE² + EF² = FD²
DE² + 63² = 65²
DE² + 3969 = 4225
DE² = 4225 - 3969
DE² = 256
DE = √256 = √(16*16)
DE = 16 cm
ΔCBD,
BC² + BD² = CD²
56² +BD² = 65²
3136 + BD² = 4225
BD² = 4225 - 3136
BD² = 1089
BD = √1089 = √(33*33)
BD = 33 cm
BE = BD + DE
= 33 + 16
BE = 49 cm
Answer:
17.1 kg
Step-by-step explanation:
One stack of rice = 26.3 kg
Two stacks of rice = 2 *26.3 = 52.6 kg
Remaining rice at end of day = Total weight of two stacks - quantity of rice sold in day
= 52.6 - 35.5
= 17.1 kg
