Answer:
Step-by-step explanation:
1/R = 1/R1 + 1/R2
R = 15
R1 = 23
The best way to do this question is to convert the resistances to decimals.
1/R = 1/15 = 0.0666666
1/R1 = 1/23 = .04348
0.066666666 = 0.0438 + 1/R2 Subtract 0.0438 from both sides.
0.023188 = 1/R2 Take the reciprocal of both sides.
43.125 = R2
========================
You can use fractions if you prefer. But it will a lot messier.
1/15 - 1/23 = 1/R2
23/345 - 15/345 = 1/R2
8/345 = 1/R2 Take the reciprocal of both sides.
345/8 = R2
R2 = 43.125
Step-by-step explanation:5 times 2=10 but 6 times 2=12 not 15 so 5/6 is proportional to 10/12 not 10/15
Answer: cannot be true because cot∅ is less than zero in quadrant 2.

Apex trigonometry answer
Answer:
x'-5x=0, or x''-25x=0, or x'''-125x=0
Step-by-step explanation:
The function is infinitely differentiable, so it satisfies a infinite number of differential equations. The required answer depends on your previous part, so I will describe a general procedure to obtain the equations.
Using rules of differentiation, we obtain that . Differentiate again to obtain, . Repeating this process, .
This can repeated infinitely, so it is possible to obtain a differential equation of order n. The key is to differentiate the required number of times and write the equation in terms of x.
The answer is Line Segment SR.
Line Segments RX and TC have the same measurement, and has a right angle at point X, this proves that SR is equal to the measurement of ST.
