Answer:
c
Step-by-step explanation:associative: a+(b+c)=(a+b)+c
commutative: a+b=b+a
distributive: a(b+c)=ab+ac
inverse: I think it is a times 1/a=1, doesn't matter
Answer:
Step-by-step explanation:
To find
total current= IT =?
in parallel resistor inductor circuit =ET =EL= ER = 240V
IT = Square root [ (IR)² + (IL)²]
IR = ER/R
= 240V / 27kΩ
= 240V / 27000Ω ( IKΩ = 1000Ω)
= 0.008 ampere.
IL = EL / XL
= 240V / 47 KΩ
=240 V / 47000Ω ( IKΩ = 1000Ω)
= 0.005 amperes
IT = Square root [ (0.008)² +( 0.005) ²]
= Square root [ 8.9 ×10^-5]
= 9.4×10^-3 ampere
Answer: Angle C has the largest measure.
The general rule of thumb is this: the largest angle is always opposite the largest side of the triangle.
We see that AB = 3.8 is the largest side, meaning that angle C is the largest angle which is opposite of AB. We don't need to actually find the value of angle C. Though optionally you can use the law of cosines to do so (and compare with the values for angles A & B to help confirm the answer).
note: a similar rule is that the smallest side is always opposite the smallest angle. The smallest angle in this case is angle B. The order of the angles from smallest to largest is B, A, C.
Okay to find percentages of things you have to take that original value (1500) and multuply it by the percentage. But when you multiply you put the percentage into a decimal and move it over to the right side two decimal places to the left. For example 10.0% would mean you need to multiply by 0.10 okay?
So for this problem you need to do 1500 *.013 and you get 19.5 computers.
h = 
multiply both sides by 2 to eliminate the fraction
2a = h(a + b ) ← ( divide both sides by (a + b ) )
h =
