Answer:

6

Step-by-step explanation:

We are going to use PEMDAS to solve this. PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You use it to determine the order of operations you use.

So there are no parenthesis or exponents, so we skip right to multiplication.

3+3 x 3 - 3 + 3

^ 3 x 3 = 9

So now we have 3+ 9 - 3 +3

There is no division, so lets move to addition.

3+9 - 3 + 3

^ 12 ^ 6 Our equation is now 12-6

12-6 = 6, so the answer to this equation is 6

2 sin^2 (x) + 3 sin (x) + 1 = 0<br> help me find the solution

Fed [463]

Answer:

Step-by-step explanation:

\[2~ sin^2 x+3sin x+1=0\]

\[2sin^2x+2sin x+sin x+1=0\]

2sinx(sin x+1)+1(sin x+1)=0

(sin x+1)(2 sin x+1)=0

either sin x+1=0

sin x=-1=sin 3π/2=sin (2nπ+3π/2)

x=2nπ+3π/2,where n is an integer.

or 2sin x+1=0

sin x=-1/2=-sin π/6=sin (π+π/6),sin (2π-π/6)=sin (2nπ+7π/6),sin (2nπ+11π/6)

x=2nπ+7π/6,2nπ+11π/6,

where n is an integer.

Which shows the following expression after the negative exponents have been eliminated?

gregori [183]

<u>Answer:</u>

The correct answer option is $\frac {a ^ 3 b^4 } {a b^2}$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to figure out which of the given answer options show the expression after the negative exponents have been eliminated:

$\frac {a^3 b^{-2}} {a b^{-4}}$

When negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator.

$\frac {a^3 b^4} {ab^2}$

Answer:

8 x = 60.10251159

9 x = 3.66062978

Step-by-step explanation:

Hey There!

So to answer these questions we need to use the Law of sines

Consider the following image

So to find x in number 8 we setup an equation

$\frac{x}{sin90} =\frac{48}{sin53}$

now we solve for x

step 1 multiply each side by sin 90

now we have

$x = \frac{48sin90}{sin53}$

if you plug the equation in a calculator you get that

x=60.10251159

<u>( make sure if it says to round to the nearest.... that you round before entering your answer)</u>

For number 9 the equation would be

$\frac{9}{sin90} =\frac{x}{sin24}$

now we solve for x

step 1 multiply each side by sin 24

now we have

$x=\frac{9sin24}{sin90}$

if you plug this into a calculator you get that

x = 3.66062978

<u>(once again if it says to round to the nearest... make sure you round before you put in your answer.)</u>

Simplify 3(2 x - 5). -6 x - 15 6 x - 15 6 x - 8 5 x - 2

TEA [102]

the answer is 6x - 15
3 times 2x is 6x and 3 times 5 is 15. Then just combine and you get 6x - 15. Hope I helped!
