Answer:

4.69 in

Step-by-step explanation:

By sine rule:

\frac{ \sin \: 23 \degree}{a}  =  \frac{ \sin \: 90 \degree}{12}  \\  \\  \frac{ \sin \: 23 \degree}{a}  =  \frac{1}{12}  \\  \\ a = 12 \: \sin 23 \degree \\  \\ a = 12 \times 0.3907311285 \\  \\ a = 4.68877354 \\  \\ a \approx 4.69\: in

Question 1(Multiple Choice Worth 4 points) Write an expression for the perimeter of the triangle shown below: A triangle is show
GuDViN [60]

The perimeter of triangle is: 5.5x+9

Step-by-step explanation:

Lets define perimeter firsst.

A perimeter is the boundary line measurement of any closed geometric figure"

Given

Side 1:  0.3x+24

Side 2: 5x

Side 3: 0.2x-15

The perimeter of a triangle is given by:

P = Side\ 1 + Side\ 2+ Side\ 3

Putting the values

P = (0.3x+24) + (5x) + (0.2x-15)\\=0.3x+24+5x+0.2x-15\\=5.5x+9

Hence,

The perimeter of triangle is: 5.5x+9

Keywords: Perimeter, triangle

De lenguaje común a algebraico:La altura (h) de un triángulo equilátero es igual a la raíz de la diferencia
Elis [28]

La respuesta es 6.92 en su expresión más pequeña porque dice la altura de un triángulo equilátero es igual solo sacas las fórmula de la altura de un triángulo que es a^2=c^2+B^2 osea haci que sustituye con valores h^2= 8^2-4^2=h^2 8x8=64 4x4=16 64-16= √48 = 6.92

Which function below is the inverse of f (x) = 3x+5/7
stepladder [879]
To get the inverse of a function you switch f(x) - (which is really just y) - with x in the problem and try to get f(x) - (y) - alone again.

For this equation, it will look like this
Original equation: y=3x+5/7
Switch x and y: x=3y+5/7
solve to get y alone:

x       =3y+5/7
  -5/7       -5/7
x-5/7=3y+0
x-5/7=3y
divide both sides by 3
x/3 -(5/7)/3 = 3y/3
x/3 -5/21 = y
switch the equation so y is on the left
y=x/3-5/21

<span>y=x/3-5/21</span> would be the inverse :)
