<span>y=-3x has slope = -3
</span><span>
perpendicular lines, slope is opposite and reciprocal
so slope of </span>perpendicular = 1/3
answer
1/3
Answer:
"
is irrational for every nonzero integer x"
Step-by-step explanation:
The original statement is
"
is rational for some nonzero integer x."
The negation is technically:
"It is NOT true that
is rational for some nonzero integer x."
So it's expressing that it's false that
can be rational for some nonzero integer x.
This just means that
is always irrational when x is a nonzero integer.
Which can be worded as
"
is irrational for every nonzero integer x"
1. The growth rate equation has a general form of:
y = A (r)^t
The function is growth when r≥1, and it is a decay when
r<1. Therefore:
y=200(0.5)^2t -->
Decay
y=1/2(2.5)^t/6 -->
Growth
y=(0.65)^t/4 -->
Decay
2. We rewrite the given equation (1/3)^d−5 = 81
Take the log of both sides:
(d – 5) log(1/3) = log 81
d – 5 = log 81 / log(1/3)
d – 5 = - 4
Multiply both sides by negative 1:
- d + 5 = 4
So the answer is D
Sin 0 sin 3pi/2 and tan pi
cos pi/2 is -.5
cos 0 is 1
