Step-by-step explanation:
The Chord Intersection Theorem:
If 2 chords of a circle are AB and CD and they intersect at E, then
AE * EB = CE * ED.
Problem.
Two Chords AB and CD intersect at E. If AE = 2cm , EB = 4 and CE = 2.5 cm, find the length of ED.
By the above theorem : 2 * 4 = 2.5 * ED
ED = (2 * 4) / 2.5
= 3.2 cm.
is this what u wanted??????????
y = 3x - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here slope m = 3
y = 3x + c ← is the partial equation
to find c substitute (- 2, - 7 ) into the partial equation
- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1
y = 3x - 1 ← equation in slope- intercept form
Answer: i am a 7th grade child and i dont know an idea of how to solve this..... just kidding but its b :) hopefully this will help u
Step-by-step explanation:
<span>6x^2 + 12x – 7 = 0
Use the quadratic formula:
x = 0.47 and x = -2.47

Answer:
c ∛ (16)
Step-by-step explanation:
2 ^ (4/3)
We can separate this into 2 pieces using the power of power rule in reverse
x^a ^b = x^ (ab)
(2^4 ) ^ 1/3
2 to the 4th power is
16 ^ (1/3)
We now have the cubed root of 16
∛ (16)
