14. Two cars are traveling on two different roads that are perpendicular to each other. On a coordinate

Klio2033 [76]

Answer:

-68/7

Step-by-step explanation:

slope1 of Car 1 that pass (-5,-8) (2,7)

= (y1-y2)/(x1-x2)=(2-(-5))/(7-(-8))=7/15

Slope2 of car 2 that pass (5,1) (10,y)

slope 1 and slope2 are perpendicular =>slope 2 =-15/7

make slope2 y=(-15/7)x+b

for it pass(5,1) => 1=(-15/7)5+b =>b=82/7 => y=(-15/7)x+82/7

put (10,y) in => y=(-15/7) 10+82/7=-68/7

Determine the angle at the centre of a circle with radius 6.0 cm for an arc length of 8.0 cm.

sveta [45]

Answer:

Third option.

Step-by-step explanation:

You need to remember that the formula used to calculate the arc lenght is:

$arc\ length=r C$

Where "r" is the radius and "C" is the central angle in radians.

You need to solve for "C":

$C=\frac{arc\ length}{r}$

You know the radius and the arc lenght, therefore, you can substitute values to calculate the central angle in radians. Therefore, this is:

$C=\frac{8.0cm}{6.0cm}$

$C=\frac{4}{3}radians$
