If a is an arbitrary nonzero constant, what happens to a/b as b approaches 0

Stolb23 [73]

It depends on how b approaches 0

If b is positive and gets closer to zero, then we say b is approaching 0 from the right, or from the positive side. Let's say a = 1. The equation a/b turns into 1/b. Looking at a table of values, 1/b will steadily increase without bound as positive b values get closer to 0.

On the other side, if b is negative and gets closer to zero, then 1/b will be negative and those negative values will decrease without bound. So 1/b approaches negative infinity if we approach 0 on the left (or negative) side.

The graph of y = 1/x shows this. See the diagram below. Note the vertical asymptote at x = 0. The portion to the right of it has the curve go upward to positive infinity as x approaches 0. The curve to the left goes down to negative infinity as x approaches 0.

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess

ANEK [815]

Answer:

See below in bold.

Step-by-step explanation:

Here is 1 grain on square 1 , 2 on square 2, 4 on square 3 and so on. This is a geometric sequence with the nth term = a1r^(n - 1) where a1 = first term , r = common ratio.

So the 20th term (the number of grains on square 20) would be

1*2^(20-1) = 524,288.

Total = a1 * (r^n - 1) / (r - 1)

= (2^20 - 1) / 2-1 = 1.048,575

8) If the resistance in an electrical circuit is held constant, the amount of current flowing through the 8) circuit is directly

Len [333]

Answer:

C) 80 milliamperes

Step-by-step explanation:

The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:

$I \propto V\\\\I = \frac{1}{R}V$

Here, $\frac{1}{R}$ is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes( $40 \times 10^{-3}$ amperes) current flow through the circuit. Using these values we can find the value of proportionality constant. i.e.

$40 \times 10^{-3}=\frac{1}{R} \times 2\\\\ \frac{1}{R}=20 \times 10^{-3}$

Using this value, we can establish the relation between I and V as:

$I = 20 \times 10^{-3} \times V$

Now, we need to calculate value current (I) if voltage is equal to 4 volts. Substituting V = 4 in above equation, we get:

$I = 20 \times 10^{-3} \times 4\\\\ I = 80 \times 10^{-3}$

Thus, the value of current will be 80 milliamperes

Yuson used her calculator to solve the equation 4/5x - 8 = 3. She entered the following on her screen and got an incorrect answe

Firlakuza [10]

Answer:

55/4

Explanation:

Let's solve your equation step-by-step.

4 /5x−8=3

Step 1: Add 8 to both sides.

4 /5x−8+8=3+8

4 /5 x = 11

Step 2: Multiply both sides by 5/4.

( 5 /4 )*( 4 /5 x)=( 5 /4 )*(11)

x= 55/4

Answer:

x=

55 /4

Hope that helps :)
