Answer:
4n -13
Step-by-step explanation:
notice that the difference between the adjacent terms is 4.
nth term is given by:
nth term = first term + (n-1) × difference -n is any number
= -9 + (n-1) × 4
= -9 + 4n -4
= 4n -13
Step-by-step explanation:
90 degree - 22 degree = 68 degree
use sin rule
sin90/x = sin68/56
x =60.4 degree
Points are (T,S) = (time, pounds), so you have (3.5, 605) and (10, 2100). Slope is (2100-605) / (10-3.5) = 1495/6.5 = 230. T is the independent variable (like x normally is in linear equations), so that narrows it down to choice A or choice D due to the slope. You can solve for b in y=mx+b or S = mT + b by plugging in one of the points: 2100 = 230(10) + b ===> b = -200. Therefore S = 230T - 200; S(12) = 230*12 - 200 = 2560 lbs [B]
<span>2) (a) Plug in 10 for x </span>
<span>(b) 10000 = 298.94x + 3215.48 </span>
<span>6784.52 = 298.94x </span>
<span>x = 6784.52/298.94 = 22.7 ===> in year 2023</span>
