R = 8 tan(x) sec(x)
In order to solve this, we are going to use the following:
r = sqrt(x^2 + y^2) //but in this case, we don't need this.
tan(x) = Y / X
X = r cos(x)
Y = r sin(x)
<span>(r cos x)^2 = 8(r sin x)</span>
x^2 = 8y
(x + 5)²z
(x + 5)(x+ 5)z
(x² + 5x + 5x + 25)z
(x² + 10x + 25)z
(x²)z + (10x)z + (25)z
x²z + 10xz + 25z
Victoria is 9. Her neighbor is 5.
Answer:
405.
Step-by-step explanation:
This is a geometric sequence where the nth term = a1 r^(n -1).
Here a1 = 5 and r = 3 so
the fifth term a5 = 5(3)^(5-1)
= 5 * 81
= 405.
