Answer:

25.5

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships between angles and sides and trig functions in a right triangle. Here, the side adjacent and the side opposite the marked angle are also marked. That means the relevant trig relation is ...

Tan = Opposite/Adjacent

tan(49°) = x/(22.2 m)

Multiplying by the denominator, we get ...

x = (22.2 m)tan(49°) ≈ 25.5 m

The unknown side is about 25.5 meters.

What is the equation in slope-intercept form of a line parallel to y=−2x+5 and passes through the point (4, 0)?

ser-zykov [4K]

Parallel lines have the same slope

The equation of the line is: $y = -2x+8$

The equation is given as:

$y = -2x + 5$

The slope intercept form of an equation is:

$y = mx + b$

Where:

$m \to slope$

By comparison,

$m = -2$

The line is said to be parallel to $y = -2x + 5$ .

This means that the line has a slope of $m = -2$

The equation of the line is then calculated as:

$y = m(x - x_1) + y_1$

Where:

$(x_1,y_1) = (4,0)$

So, we have:

$y = m(x - x_1) + y_1$

Substitute values for m, x1 and y1

$y = -2(x - 4) + 0$

$y = -2(x - 4)$

Open brackets

$y = -2x+8$

Hence, the equation of the line is: $y = -2x+8$

See attachment for the graphs of $y = -2x+8$ and $y = -2x + 5$

There are approximately 1.35 billion people in China. If the world population is 7.1 billion people, what percent of the world p

wlad13 [49]

Answer:

19.01%

Step-by- step explanation:

$Percentage = \frac{1.35 billion }{ 7.1 billion } \times 100$

$= \frac{ 1.35 \ times 1, 000, 000, 000} {7.1 \times 1,000,000,000} \times 100\\\\\\=\frac{1.35}{7.1} \times 100 = 19.01 \%$
