Answer:
4782969
Step-by-step explanation:
the equation for finding a term (IN A GEOMETRIC series) is a1(r)^(n-1)
a1=first term
r=ratio
n=the number you want
you can see that the sequence increases by the eponent of 3 increasing y 1 each time. So for the first time 3^0=1,3^1=3, 3^2=9 and so on. So we can determine that the ratio is 3.
so now we can plug all that information into the equation
1(3)^(15-1)=the 15th term
4782969=15th term
Hope that helps :)
Answer: 360 - 44 - 80 = 236
236 ÷ 2 = 118
both angle equal to 118

Those lines that the numbers are in mean absolute value.
Basically it means distance from zero in any direction.
The answer is B) 4.8x10 to the 7th power
Answer:
-2
Step-by-step explanation:
Dividing the given equation by x, we find y to be ...
y = -2/x
Then ...
dy/dx = 2/x^2
and ...
dy/dt = (2/x^2)dx/dt
dx/dt = (x^2/2)dy/dt
When dy/dt = -4 and x=-1, this is ...
dx/dt = (-1)^2/2(-4) = (1/2)(-4)
dx/dt = -2
