Answer:
15
Step-by-step explanation:
.5 * 30 = 15
Let's do 51 and 52.
51. The contrapositive has the same truth value as the original statement. That's opposed to the converse, which may or may not be true independent of the original statement.
The contrapositive of IF P THEN Q is IF not Q THEN not P. They're equivalent. Here that's If the cat is not female then it is not tricolor.
Answer: C
52.


For the statement to be true, the exponent must be zero:



Both positive 2 and negative 2 have a square of 4.
Answer: K
By the way, usually we assume
so the restriction that
isn't really necessary. Think of the definition of a polynomial or the binomial expansion:


For these common equalities to work when
we need to define 
Answer:
cos 45 degree = A/H
cos 45 degree = 2 square root 2 / x
x = 2 square root 2 / cos 45 degree
x = 4
Sin 45 degree = O/H
Sin 45 degree = y/ 4
4 x Sin 45 degree = y
y = 2.83
or
we could use tan
tan 45 degree = O/A
tan 45 degree = y / 2 square root 2
2 square root 2 x tan 45 degree = y
y = 2.83
i hope this would elp a little bit.
<h2>
The "option d:
+ 13x + 12" is a trinomial with a constant term.</h2>
Step-by-step explanation:
To check options:
a: x + 4y
Here, the coefficient of x = 1 and the coefficient of y = 4
b: 
Here, the coefficient of
= 1
c:
+ 3
+ 2y
Here, the coefficient of
= 1, the coefficient of
= 4 and the coefficient of y = 2
d:
+ 13x + 12
Here, the coefficient of
= 1, the coefficient of x = 13 and
constant term = 12
Thus, the "option d)
+ 13x + 12" is a trinomial with a constant term.
