Answer:
the sequence is the a geometric sequence because the terms has a common ratio. the common ratio = -80 / 200 = -2 / 5common ratio = 32 / -80 = -2 /5
so the next to term can be solve multiplying the last term with the common ratio
x = -12.8 ( -2 / 5)x = 5.12
y = 5.12 ( - 2 / 5)y = -2.048
Step-by-step explanation: HOPE THIS HELPS!!
If you're asking if they are linear, quadratic, etc. They are linear lines.
7. the wall is 12 the ladder is 15 find the ground
this will make a right angle from the wall and the ground
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 both sides
b^2=81
square root both sides
b=9 ft
8. area of square is s^2
s^2=81
square root both sides s=9cm
diagonal=
a^2+b^2=c^2
9^2+9^2=c^2
81+81=c^2
162=c^2
square root both sides
12.73cm is diagonal
9. a^2+b^2=c^2
a=9
b=12
c=
9^2+12^2=c^2
81+144=c^2
225=c^2
square root both sides
c=15km
Answer:
Step-by-step explanation:
x^2 - 6x = -156 Next step is:
x^2 - 6x + (-3)^2 = -156 + (-3)^2
