Answer:
x=4, y=9.6
Step-by-step explanation:
Using Theorem of Intersecting Secant and Tangent


Next, we apply Theorem of Intersecting Chords
SV X VR=PV X VQ
5 X y = x X 12
Recall: x=4
5y=4 X 12
5y=48
y=48/5=9.6
Therefore: x=4, y=9.6
Answer:
are you a teacher
Step-by-step explanation:
Answer: 8
<u>Step-by-step explanation:</u>
60 dowels - each 6 inches (1/2 foot) in length = 30 feet of wood
30 feet of wood ÷ 4 foot boards = 7.5 boards
Since he can't buy half of a board, you must round up to 8 boards.
Germany surrendered on November 11, 1918, and all nations had agreed to stop fighting.
Answer:
a = 1
Step-by-step explanation:
Since x = - 1 is a zero of p(x) then p(- 1) = 0
Substitute x = - 1 into p(x)
p(- 1) = a(- 1)² - 3(a - 1)(- 1) - 1 = 0, that is
a + 3(a - 1) - 1 = 0
a + 3a - 3 - 1 = 0
4a - 4 = 0 ( add 4 to both sides )
4a = 4 ( divide both sides by 4 )
a = 1
