Answer:
x = .4384471872, x = 1, x = 4.561552813
Step-by-step explanation:
(x-1) is a root. When you divide it into x³-6x²+7x -2, you are left with x²-5x+2. Use the quadratic equation on that.
(5+/-)/2
So the roots are (5 - )/2, 1, and (5 + )/2
Answer:
m∠BPD = 120
mBC + mAD = 120°
Step-by-step explanation:
according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is the sum of the chords' intercepted arcs.
m∠BPD = (M∠BD + M∠CA)
= (70 + 170)
= (240)
m∠BPD = 120
We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°
Answer:
$50.85.
Step-by-step explanation:
We have been given that Jessica's Furniture Store buys a couch at a wholesale price of$113.00. The markup rate at Jessica's Furniture Store is 45%. We are asked to find the markup for the couch.
To find the markup for the couch, we need to calculate 45% of $113.00.
Therefore, the markup for the couch would be $50.85.

If it costs her [ 37x + 20 ] to be a member of the gym for 'x' months,
that means that it cost her 20 at the beginning just to sign up, before
any time went by, and then another 37 every month after that.
