Answer:
the one thats not equal to 16 is the last one; 8^2
Step-by-step explanation:
all of them equal 16 but 8^2 is 64
Answer:
√2
Step-by-step explanation:
tan(x) = -1
x = arctan(-1)
x = -π/4
Now since x is between 3π/2 and 2π use use the general form
nπ-π/4
taking n = 2
2×π-π/4
= 7π/4
now tan (7π/4) = -1
so sec (7π/4) = √2

For triangle a use Pythagorean theorem to find the hypotenuse.
A^2+b^2=c^2
15^2+9^2=c^2
225+81=306
C^2=306
C=17.49 or square root of 306
For b) 18^2+B^2=23^2
324+B^2=529
B^2=205
B=14.32 or square root of 205

Ans4: 2/3×surd11
Rational number is a number that can be expressed in ratio (quotient)
It can be expressed in the form of repeating or terminating decimal
Example:
16/3 is equal to
5.3333333333....(repeating decimal)
thus it is a rational number
1/4 is equal to
0.25 (terminating decimal)
thus it is a rational number
