What is BC will give brainliest

Mathematics
1 answer:
Alexxandr [17]4 years ago

Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.

4x + 4 = 6x - 14

Subtract 4x from both sides.

4 = 2x - 14

Add 14 to both sides.

18 = 2x

Divide both sides by 2.

x = 9.

Because we have a constant value of x, we can solve for BC.

BC = 2x + 7

2(9) + 7

18 + 7

25

<h3>The value of BC is 25.</h3>

Find the missing side lengths. Leave your answers as radicals in simplest form.

Answer:

B  x = 3, y= 3

Step-by-step explanation:

<u />

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse (the side opposite the right angle)

Given:

  • \theta = 45°
  • O = x
  • A = y
  • H = 3\sqrt{2}

\implies \sin(45^{\circ})=\dfrac{x}{3\sqrt{2}}

\implies x=3\sqrt{2}\sin(45^{\circ})

\implies x=3\sqrt{2} \cdot \dfrac{\sqrt{2}}{2}

\implies x=\dfrac{3\sqrt{2} \sqrt{2}}{2}

\implies x=\dfrac{3 \cdot 2}{2}=3

\implies \cos(45^{\circ})=\dfrac{y}{3\sqrt{2}}

\implies y=3\sqrt{2}\cos(45^{\circ})

\implies y=3\sqrt{2} \cdot \dfrac{\sqrt{2}}{2}

\implies y=\dfrac{3\sqrt{2} \sqrt{2}}{2}

\implies y=\dfrac{3 \cdot 2}{2}=3

This table defines function f:
rodikova [14]

Answer:

Neither

Step-by-step explanation:

This function isn't even, because

f(x) =   f( - x)

Basically this mean for every x opposites the y value should be the same.

Here, 6 and -6 doesn't share the same y value, nor as -3,and 3.

This function isn't odd because

f(  - x) =  - f(x)

Basically, this means our y values should be reflected about the orgin,

here, the y values does not switch signs for every x value and it's opposite itself , so this function isn't odd.

So The answer is neither

What is the sales of volume V, of a particular product with a net income of $5000 given a sales price of $40, a variable cost of
iVinArrow [24]

Answer:

The sales of volume V, of a particular product with a net income of $5000 given a sales price of $40, a variable cost of $15?and $1000 in fixed cost is 240

Step-by-step explanation:

Given:  

Net income= $5000

sales price= $40

variable cost =$15 and $1000

To Find:

sales of volume V=?

Solution:

We Know that  

\text {Income}=40 * x

Where x=  number of units sold

Similarily,  

\text { Net Income }=40 \mathrm{x}-\text { VARIABLE } \cos \mathrm{T} * \mathrm{x}-1000

Substituting the known values,

\text { Net Income }=40 \mathrm{x}-\text{VARIABLE COST} * \mathrm{x}-1000

5000=40 \mathrm{x}-15 * \mathrm{x}-1000

Sloving the equation,

5000=40 \mathrm{x}-15 \mathrm{x}-1000

5000=25 \mathrm{x}-1000

5000+1000=25 \mathrm{x}

6000=25 \mathrm{x}

x=\frac{6000}{25}

x=240
