Answer:
6.5 cm
Step-by-step explanation:
Here, <em>the tangent line squared is equal to the secant line times the secant line outside the circle</em>.
That is <em>20.2² = 14.7 * (14.7 + 2x)</em> --> it is 2x because the secant goes through <em>the whole circle</em>.
Simplify: <em>408.04 = 216.09 + 29.4x</em>
Subtract: <em>191.95 = 29.4x</em>
Divide: <em>x = 6.528911565</em> ≈ 6.5 cm
Answer:
14 square feet
Step-by-step explanation:
8x8=64
8x10=80
80-64=14
(−0.0081p)(t)=(15000)(2.718282)
Step 1: Divide both sides by -0.0081t.
−0.0081pt
−0.0081t
=
40774.227427
−0.0081t
p=
−40774.227427
0.0081t
Answer:
p=
−40774.227427
0.0081t
Answer:
x = - 2, x = 0
Step-by-step explanation:
- 3x² - 6x ← factor out - 3x from each term
= - 3x(x + 2)
To solve equate to zero
- 3x(x + 2) = 0
Equate each factor to zero and solve for x
- 3x = 0 ⇒ x = 0
x + 2 = 0 ⇒ x = - 2
Okay! So 1/4 = 2/8 and 3/8 = 3/8 3/8+2/8= 5/8
3/8 is your answer
