Answer:
a1 = 2
d = 3
an = 2 + (n - 1) * 3
a7 = 20
a59 = 176
Steps:
a1 is the initial value (when n equals 1), and since there are 2 crosses, it is 2.
d is the added value to each amount of crosses. And since the second amount is 5 and the third amount is 8, we can determine that each n is adding 3 crosses, therefore making d = 3.
The equation is simply plugging in the values for a1 and d.
A7 is simply plugging in 7 for n in the equation and solving for it. So;
a7 = 2 + (7 - 1) * 3
a7 = 2 + 6 * 3
a7 = 2 + 18
a7 = 20
And same thing as the last for 59 except substitute 59 in for where you put 7;
a59 = 2 + (59 - 1) * 3
a59 = 2 + 58 * 3
a59 = 2 + 174
a59 = 176
Rectangle
QT = RS
QR = TS
but QR = 25 and TS = 29.15
so it's false....
answer
FALSE
y = -2x + 2
slope = -2
perpendicular slope = 1/2 (-ve inverse of the slope)
coordinates (0, 1)
y - y1 = m(x -x1)
y - 1 = 1/2(x - 0)
y = 1/2x + 1
