1 answer:

7 0

If a point
(
x
,
y
)
is written as
(
r
,
θ
)
in polar coordinates, then
x
=
r
o
s
θ
and
y
=
r
sin
θ
.
As such in polar form equation
x
=
−
3
can be written as
r
cos
θ
=
−
3
or
r
=
−
3
cos
θ

Evaluate. 27 1/3 3 9 81 19,683 PLease answer fast!!

ArbitrLikvidat [17]

If you mean $27^{\frac{1}{3}}$ , then the answer is 3.

In fact, rational exponents work like this:

$a^{\frac{b}{c}}=\sqrt[c]{a^b}$

So, in your case,

$27^{\frac{1}{3}}=\sqrt[3]{27} = 3$

because $3^3 = 27$

3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)

Morgarella [4.7K]

Answer:

infinite solutions

Step-by-step explanation:

3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)

Combine like terms

3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)

15(12x2+x+1) = 15(12x2+x+1)

Divide by 15

(12x2+x+1) = (12x2+x+1)

Since they are the same

x can be any real value

|2x-5|<1 solution of inequality?

qwelly [4]

Answer:

{x:x<3}

Step-by-step explanation:

You first change the < to = in order to simply it. Thus,

2x-5=1
2x=1+5( move the -5 to the right hand side to obtain 5)
2x= 6
dividing through by 2
2x/2=6/2

x=3 . Therefore the solution is {x:x<3} sing you didn't divide with a negative number ,the < sing remains unchanged
