Answer:
0.36
Step-by-step explanation:
0.09 × -8 is -0.72, and that multiplied by -0.5 is 0.36
The distance between point C and point D is 10.
Point D is on the 1 and Point C is on -9.
1-(-9)=10.
13-4x = 1-x
13 = 3x +1
12 = 3x
4 = x
X=4
The 10 cm string is 7 times smaller than the 70 cm string
A - 3
Using the coordinates of the diameter, it is possible to figure out the radius.
Using the y axis, you can determine that 4 and -2 total to be six apart, leaving the diameter to be six. Knowing that the radius is half of the diameter, you can easily split the diameter in half to get the radius of 3.
Hope this helps!
