Answer:
Boys x 2 = Girls
Step-by-step explanation:
If there are twice as many girls in school as boys than take the number of boys and multiply that by 2. For example if there are 400 boys in school and there are twice as many girs your equation would, 400 x 2 = 800 girls.
X=-10
by simplifying both sides of the equation then isolating the variable
Answer is -7
=============================================
Work Shown:
s_n = a_1*(1-r^n)/(1-r)
s_6 = a_1*(1-r^6)/(1-r)
s_6 = x*(1-(-3)^6)/(1-(-3))
s_6 = x*(1-729)/(1+3)
s_6 = x*(-728)/4
s_6 = x*(-182)
s_6 = -182x
-182x = s_6
-182x = 1274
x = 1274/(-182)
x = -7 is the first term of the geometric sequence
------------
Extra info:
The first six terms of this geometric sequence is
-7, 21, -63, 189, -567, 1701
those six terms add to
-7+21+(-63)+189+(-567)+1701 = 1274
which verifies we have the right answer.
Answer:
(1, 0)
Step-by-step explanation:
360º is a full circle and is the same as 0º, so this is on the x-axis.
the y coordinate is 0
Since it's a unit circle on the x-axis the x coordinate is 1
(1, 0)
