Answer:
B
Step-by-step explanation:
Answer:
y=2x-7
Step-by-step explanation:
The easiest way to answer this would be by using the slope-intercept form equation, y=mx+b. In this case, we can use our given in information to plug in values and find the equation.
Firstly, let's assess what know and what we don't:
Given the point (2,-3), we know that x=2 and y=-3. Now the slope for a perpendicular line can be found using a negative reciprocal, since the product of the slopes of both lines should equal -1. Therefore the slope must be 2.
All that's left is b, the y-intercept. To solve for this, we simply plug in what we have.
y=mx+b
-3=2(2)+b
-3=4+b
-3-4=b
-7=b
Now that we have b, we can write the equation:
y=2x-7
Answer:
The correct answer is Option 1: s = 4/9pi feet
Step-by-step explanation:
Given that
The radius of circle is 8 feet
r = 8
Central angle is:10°
The arc length is denoted by s and is calculated by the formula:
Here x is the central angle
Putting the known values we will get:
The arc length is 4/9 pi feet.
Hence,
The correct answer is Option 1: s = 4/9pi feet
