Answer:
ln 2.
Step-by-step explanation:
One of the rules of logarithms is
ln a - ln b = ln a/b.
So ln 16 - ln 8 = ln 16/8
= ln 2.
Answer:
x = 6, z = 5.66 to nearest hundredth.
y = 90 degrees.
Step-by-step explanation:
From the chord intersection theorem 12*4 = 8 * x
So x = 6.
By the tangent / chord theorem:
z^2 = 2 * (12+4)
z^2 = 32
z = 5.66.
I'm not 100% sure of the value of angle y but I think its
1/2(100 + 80) = 90 degrees.
I'll try and check that out.
Yes that is right.
Answer:
y= -3/8x + 1
Step-by-step explanation:
-4 = x1
5 = y1
y-y1=m(x-x1)
y-5 = -3/8(x-(-4)
y-5 = -3/8x + -3/2
+5 +5
y= -3/8x + 1
