What is the slope?<br>if possible can you explain?​
Mandarinka [93]

Answer:

m =  \frac{4}{5}

Step-by-step explanation:

The slope of a graph is also known as its gradient, which is the steepness of the graph.

If we are given two points on the line, we can find the slope by taking rise/ run, which is the ratio of the change in y-coordinate against the change in the x-coordinate. This can also be written as a formula:

\boxed{slope =  \frac{y1 - y2}{x1 - x2} }

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

In this question, we are given the equation of the line. This equation is already in the slope-intercept form (y= mx +c) since the coefficient of y is 1 and all the other terms are on the other side of the equal sign. In the slope-intercept form, m is the slope while c is the y-intercept.

m= ⅘ since the coefficient of x is ⅘ in the given equation (when the equation is in the slope-intercept form).

Find the measurement of arc ac whose inscribed angle is 62 degrees
DerKrebs [107]
This the concept of circumference of circle. The arc length will be given by:
C=theta/360*pi*diameter
theta=62
diameter=d
thus the arc length will be:
C=62/360*π*d
C=0.54d

40 points: how do u calculate this and what is sin, cos and what is the formula
dlinn [17]

Answer:

B.

Step-by-step explanation:

sin∅ = opposite side over hypotenuse

cos∅ = adjacent side over hypotenuse

To find <em>x</em>, there are multiple ways:

tan72° = 6/x

x = 6/tan72°

cos72° = x/15

15cos72° = x
