Answer:
(–1, 1)
(4, –2)
Step-by-step explanation:
Let
(x,y) ----> the coordinates of point C
Applying the Pythagoras Theorem
step 1
Find the possibles values of x
Simplify
Solve the quadratic equation
The values of x are
x=-1 and x=4
step 2
Find the possibles values of y
Simplify
Solve the quadratic equation
The values of y are
y=-2, y=1
therefore
The possibles coordinates of point C are
(-1,1),(4,-2)
16 because when the line is on the x-axis, it is on zero
The answer is x=-6
2+(-3x)+(-7)=-x+19
-3x+-5=-x+19
-3x=x+24
-4x=24
x=-6
That depends.
-- If you're rounding to the nearest ten-thousandth, it's 4.5713 .
-- If you're rounding to the nearest thousandth, it's 4.571 .
-- If you're rounding to the nearest hundredth, it's 4.57 .
-- If you're rounding to the nearest tenth, it's 4.6 .
-- If you're rounding to the nearest whole number, it's 5 .
-- If you're rounding to the nearest ten, or to any larger place, it's zero.
The formula for the secants of a circle is, in this case, (AB + BC) x BC = (ED + DC) x DC. After plugging in the known values we get: (ED + 10) x 10 = 420. Next, we can solve and get: ED = 32. Finally, we add up ED and DC and get a final answer of D. 42.
Hope this helps!
