You have to use the distance formula which is:
Distance = √(x2 - x1)^2 + (y2 - y1)^2
Using the coordinates given.
D = √(4 - (-2)^2 + (1 - 4)^2
D = √(6)^2 + (-3)^2
D = √36 + 9
D = √45
D = √9 × 5
D = 3√5
Answer:
2.68
Step-by-step explanation:
2/4=1.34/x
solve proportion
2x=5.36
divide both sides by 2
5.36/2
=2.68
The correct answer is A.
Each y value is equal to -4 times the x value.
-4*-4=16
0*-4=0
4*-4=-16
8*-4=-32
Answer:
x = 40
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20)
8(8 + x) = 12 × 32 = 384 ( divide both sides by 8 )
8 + x = 48 ( subtract 8 from both sides )
x = 40
B=160+ 5c
b= 304- 3c
160+5c=304-3c
+3c +3c
160+8c=304
-160 -160
8c= 144
c=18
