Answer:

Step-by-step explanation:
step 1
Find the slope of the given line
The formula to calculate the slope between two points is equal to

we have
(-2,5) and (-4,8)
substitute the values in the formula



step 2
Find the slope of the perpendicular line to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
so

----> slope of the given line
therefore
---> slope of the perpendicular line to the given line
step 2
Find the equation of the line in point slope form

we have


substitute

step 3
Convert to slope intercept form

isolate the variable y



Answer:
Ty covered the least distance per min.
Step-by-step explanation:
Who covered the shortest distance per minute, or who rode his bike most slowly?
Andre's rate: (750 m) / (3 min) = 250/3 m/min
Rick's rate: (800 m) / (4 min) = 200 m/min
Ty's rate: (950 m) / (5 min) = 190 m/min
Ty was the rider who covered the least distance per minute; his rate was the slowest.
Answer:
6.6
Step-by-step explanation:
Answer:
1.32
Step-by-step explanation:
Consider ...
x = sec⁻¹(4) . . . . . the inverse secant function of 4, also written arcsec(4)*
Taking the secant of both sides, we have ...
sec(x) = 4
Writing this in terms of more familiar functions, it is ...
1/cos(x) = 4
cos(x) = 1/4
Now, we can use a calculator to find the inverse function. Be sure the calculator is in the appropriate angle mode. We suspect the desired result is in radians.
x = cos⁻¹(1/4) ≈ 1.318116
sec⁻¹(4) ≈ 1.32 . . . . . radians
_____
* One way to read this is "the angle whose secant is 4." This helps remind you that the result is an angle, so can be in degrees or radians (or any of several other angle measures).
i get 11/2 is this wright answer??
