Answer:
Step-by-step explanation:

Given:
Consider the below figure attached with this equation.
To find:
Length of side ZX.
Solution:
From the figure it is clear that, WXY is a right angled triangle.
According the 30°-60°-90° theorem, the longer leg (opposite to 60° angle) of the right-angled triangle is
times of shorter leg (opposite to 30° angle).
In the below figure, WY is longer leg and XY is shorter leg.



So, the length of XY is 8 units.
VWYZ is a rectangle, so

Now,



So, the length of ZX is 18 units.
Therefore, the correct option is C.
Answer:
growth rate is the number of times the base repeats
Step-by-step explanation:
We have that the general form of the exponential function is of the type:
f (x) = a ^ x
where "a" is the base and "x" is the exponent.
Therefore, the relation they keep to this exponent would be the growth rate since it is the number of times that the base is repeated, which means that the higher "x" is, the more times "a" is repeated.
Answer:
x = ± 
Step-by-step explanation:
To find the zeros equate the polynomial to zero, that is
x² - 7 = 0 ( add 7 to both sides )
x² = 7 ( take the square root of both sides )
x = ±
Thus the exact solutions are
x = -
