Answer:

Yes

Step-by-step explanation:

A yard is equivalent to 3 feet. If a singular doormat is 2 feet long then two doormats placed in a line would be 4 feet long. 4 > 3 meaning they would be longer than a yard.

And right triangle sin (40 - x)° equals cos(3x)° degrees what is the value of x.

Drupady [299]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

$\qquad \sf \dashrightarrow \: \sin(40 - x) = \cos(3x)$

$\qquad \sf \dashrightarrow \: \cos\{90 - (40 - x ) \} = \cos(3x)$

$\qquad \sf \dashrightarrow \:90 - (40 - x) = 3x$

$\qquad \sf \dashrightarrow \:90 - 40 + x = 3x$

$\qquad \sf \dashrightarrow \:3x - x = 50$

$\qquad \sf \dashrightarrow \:2x = 50$

$\qquad \sf \dashrightarrow \:x = 25 \degree$

Pls help it due ASAP. Please show workings It due in a hour....

Answer:

C. $\frac{4}{5}$

Step-by-step explanation:

In order to find the slope knowing two points, use the slope formula $\frac{y_2 - y_1}{x_2-x_1}$ . $x_1$ and $y_1$ represent the x and y values of one point the line intersects, and $x_2$ and $y_2$ represent the x and y values of another point the line intersects.

Knowing this, use the points (-4, -4) and (6, 4) for the formula. Substitute -4 for $x_1$ , -4 for $y_1$ , 6 for $x_2$ , and 4 for $y_2$ . Then, simplify:

$\frac{(4) - (-4)}{(6) - (-4)} \\= \frac{4+4}{6+4} \\= \frac{8}{10} \\= \frac{4}{5}$

Thus, $\frac{4}{5}$ is the slope of the line.
