B. y = 9x^2; each y-value is the previous y-value plus 9 more than was added previously.
Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100

Amount paid for next 50 watches = (55% of 80) * 50

Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125

Amount received by the watch maker = 5200 + 2200 + 4500
= £ 11900
Cos angle = adj/hyp
3 is the adj, -4 is the opposite, so use Pythagorean theorem to find the hypotenuse.
3^2 + (-4)^2 = c^2
9 + 16 = c^2
25 = c^2
5 = hyp
Cos angle = 3/5
To find angle use cos^-1
Cos^-1 (3/5) = angle
Angle =
53.1 degrees
Answer:
55.17
Step-by-step explanation:
2.8 + 9.46 = 12.26
12.26 x 4.5 = 55.17
