What does the zigzag line in the circuit diagram represent?

2 answers:

<span>the zig zags are resistors, the thing on the left is the symbol for a battery. Sometimes a single cell (1.5V); you'd draw a few more plates to show a higher voltage battery. But a DC supply, anyway. The long line is supposed to be the positive terminal.</span>

The population od a small country is 5,740,000. Express this number using scientific notation. Say steps to.

bija089 [108]

5,740,000( you have to make the number less than 10

5.740000 ( you put a decimal to make it less )

5.74e6 (you count how many times you skipped over to get at the decimal point , and that's your awnser .

A person is standing 50 ft from a statue. The person looks up at an angle of elevation of 8 degrees when staring at the top of t

borishaifa [10]

The height of the statue is 19.5 feet.

Why?

We can solve the problem using trigonometric formulas. In this case, we are going to use the trigonometric formula of the tangent.

We know that the person is standing 50ft from the statue, so, it will be the base of the two triangles formed by both angles (elevation and depression)

Using the trignometric formula, we have:

First triangle:

$tg(\alpha )=\frac{h_{1}}{base} \\\\tg(8\°)=\frac{h_{1}}{50ft}\\\\0.14*50ft=h_1\\\\h_1=7ft$

Second triangle:

$tg(\alpha )=\frac{h_{2}}{base} \\\\tg(14\°)=\frac{h_{1}}{50ft}\\\\0.25*50ft=h_1\\\\h_1=12.5ft$

Now, the total height of the statue will be:

$TotalHeight=h_1+h_2=7ft+12.5ft\\\\TotalHeight=19.5ft$

Have a nice day!

Assume equal likelihood for the birth of boys and girls. What is the probability that a four-child family chosen at random will

garik1379 [7]

Each child has a 50% chance to be a girl and 50%chance to be a boy so with 4 children the probability is
$\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{16}$
