Find the image of point (-3,5) under enlargement with centre at(-2,-6), with scale factor 4​

Explanation:

Solution 1 :)

Let  

k

be the scale factor, when  

k

is negative, the "image" triangle is on the opposite side of the center of the dilation  

O

(vertices are on opposite side of O from the preimage). Also note that the triangle has been rotated 180º.

Step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
