How do you find a rate of change

ddd [48]

Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, the rate of change<span> (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis.hope this helped. </span>

How do you do trigonometric Ratios<br>

iren2701 [21]

To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.

Determine the length of the legs in the right triangle below.

Marysya12 [62]

Answer:

x = 14

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (14 $\sqrt{2}$ )²

2x² = 392 ( divide both sides by 2 )

x² = 196 ( take the square root of both sides )

x = $\sqrt{196}$ = 14

Thus the congruent legs are 14 cm
