The law of sine is the nothing but the relationship between the sides of the triangle to the angle of the triangle (oblique triangle).

The value of the z is 3.2 (rounded to the nearest tenth). The option 2 is the correct option.

<h3>What is law of sine?</h3>

The law of sine is the nothing but the relationship between the sides of the triangle to the angle of the triangle (oblique triangle).

It can be given as,

\dfrac{\sin A}{a} =\dfrac{\sin B}{b} =\dfrac{\sin C}{c}

Here A,B,C are the angle of the triangle and a,b,c are the sides of that triangle.

Given information-

The triangle for the given problem is attached below.

In the triangle the base of the triangle is 2.6 units long.

The sine law for the given triangle can be written as,

\dfrac{\sin X}{x} =\dfrac{\sin Y}{y} =\dfrac{\sin Z}{z}

As the value of y side is known and the value of z has to be find. Thus use

\dfrac{\sin Y}{y} =\dfrac{\sin Z}{z}

Put the values,

\dfrac{\sin 51}{2.6} =\dfrac{\sin 76}{z}

Solve it for the z,

z=\dfrac{\sin 76\times 2.6}{\sin 51}\\z=3.2462

Hence the value of the z is 3.2 (rounded to the nearest tenth). The option 2 is the correct option.

Suppose we want to build a rectangular storage container with open top whose volume is $$12 cubic meters. Assume that the cost o
Snezhnost [94]

Answer:265.25

Step-by-step explanation:

Given

Volume of box=12 m^3

height is 3 times the width

let height, length and breadth be H, L & B

H=3\times B

V=12=L\times B\times H

4=B^2\times L[/tex]

L=\frac{4}{B^2}

Cost of side walls $ 8/m^2

Cost of base $ 12/m^2

Cost of side walls=(2LH+2BH)\cdot 8

Cost of base =12LB

Total cost C=16LH+16BH+12LB

C=48LB+48B^2+12LB

C=\frac{192}{B}+48B^2+\frac{48}{B}

differentiate C w.r.t B to get minimum cost

\frac{\mathrm{d} C}{\mathrm{d} B}=-\frac{192}{B^2}+2\times 48 B-\frac{48}{B^2}

B^3=\frac{240}{2\times 48}

B=1.35 m

H=3\times 1.35=4.07 m

L=2.19 m

C=$ 265.25

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0 ​
Arturiano [62]

Slope intercept form is y = mx+ b

So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!

Let's do it!

  • add 3x to the right side of the equation

<u>5y - 3x + 20 = 0</u>

<u>5y + 20 = 3x </u>

  • move 20 to the right side

<u>5y = 3x - 20 </u>

  • Divide both sides of the equation by 5

y = 3/5x - 4

This is our answer!

I hope I helped! Leave a comment if you have any questions or concerns
