Describe and correct the error made in finding BC in the diagram

Answer:

Podemos determinar la velocidad del automóvil mediante diferencias sucesivas tanto en el dominio del tiempo como en el dominio de la posición:

Dominio del tiempo

[tex]v_{i+1} = v_{i} + a_{i}\cdot \Delta t[/tex]

Dominio de la posición

[tex]v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}[/tex]

Step-by-step explanation:

En este caso, es necesario tener una función que represente a esta en función del tiempo o de la posición si nos basamos en las definiciones diferenciales de aceleración ([tex]a(t)[/tex]), medida en metros por segundo al cuadrado, es:

[tex]a(t) = \frac{dv}{dt}[/tex] (1)

[tex]a(s) = v(t)\cdot \frac{dv}{ds}[/tex] (2)

Donde:

[tex]v(t)[/tex] - Velocidad del automóvil, medida en metros por segundo.

[tex]\frac{dv}{dt}[/tex] - Primera derivada de la velocidad con respecto al tiempo, medida en metros por segundo.

[tex]\frac{dv}{ds}[/tex] - Primera derivada de la velocidad con respecto a la posición, medida en [tex]\frac{1}{s}[/tex].

A continuación, analizamos cada ecuación:

Eq. 1

Procedemos a despejar la diferencial de velocidad e integramos la expresión resultante:

[tex]v_{f}-v_{o} = \int {a(t)} \, dt[/tex] (3)

[tex]v_{f} = v_{o}+\int {a(t)} \, dt[/tex]

Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:

[tex]v_{i+1} = v_{i} + a_{i}\cdot \Delta t[/tex] (3b)

Eq. 2

Procedemos a despejar la velocidad e integramos la expresión resultante:

[tex]\int {v} \, dv = \int {a(t)} \, ds[/tex] (4)

[tex]\frac{1}{2}\cdot v_{f}^{2}-\frac{1}{2}\cdot v_{o}^{2} = \int {a(s)} \, ds[/tex]

[tex]\frac{1}{2}\cdot v_{f}^{2} = \frac{1}{2}\cdot v_{o}^{2}+\int {a(s)} \, ds[/tex]

[tex]v_{f}= \sqrt{v_{o}^{2}+2 \int {a(s)} \, ds }[/tex]

Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:

[tex]v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}[/tex] (4b)

Answer:

Symmetric Property of Congruence

Step-by-step explanation:

Reflexive:

A ~= A

B ~= B

Symmetric:

A ~= B then B ~= A

Transitive:

If A ~= B and B ~= C, then A ~= C

I think it is Yes, SAS

Step-by-step explanation:

Answer:

x = 1

y = 6

Step-by-step explanation:

y = 6x   --------------(I)

7x - 8y = -41   ------------(II)

Substitute y =6x in equation (II)

7x - 8*(6x) = -41

7x - 48x    = -41   {Combine like terms}

     -41x = -41

          x = -41/-41

x = 1

Plug in x = 1 in equation (I)

y = 6*1

y = 6

Answer:

The equation of a circle is:

(x−x0)2+(y−y0)2=R2  

where  x0  and  y0  are the center of the circle  (x0,y0)  and  R  is the radius of the circle.

Step-by-step explanation:

Step-by-step explanation:

The equation of the circle is (x + 10)² + (y + 6)² = 81.

Answer:

y int is (0,5)

slope is m=-2

y=-2x+5

Step-by-step explanation:

The line has a slope of -2 and a y-intercept of y=4. (y=-2x+4)

Explanation: You can tell by where the line is landing on the x and y intercepts and it's as easy as counting lines. As far as the y-intercept goes, you can tell that by looking where the line crosses the y axis. And in this case it's (0,4) making your y-intercept, y=4.

Answer:

MO = 8 units

MP = 4 units

Step-by-step explanation:

[tex] In\: \triangle MOP, \\

\angle P = 90\degree ... (given) \\

\angle M = 60\degree ... (given) \\

\therefore \angle O = 30\degree(3^{rd} \: \angle \: of\: \triangle) \\

Let \huge\purple {MO = x \: units}... (1)\\

\therefore MP = \frac{1}{2} \times MO\\(side\: opposite \: to\: 30\degree) \\\\

\therefore MP = \frac{1}{2} \times x\\\\

\huge\red {\therefore MP = \frac{1}{2} x}.... (2)\\\\

\therefore PO = \frac{\sqrt 3}{2} \times MO\\(side\: opposite \: to\: 60\degree) \\\\

\therefore PO = \frac{\sqrt 3}{2} \times x\\\\

\huge\orange{\therefore PO = \frac{\sqrt 3}{2}x} \\\\

\because MP + PO + MO = P(\triangle MOP) \\\\

\therefore \frac{1}{2} x+\frac{\sqrt 3}{2}x+ x = 12+4\sqrt 3\\\\

\therefore \frac{1}{2} x+x+\frac{\sqrt 3}{2}x= 4(3+\sqrt 3)\\\\

\therefore \frac{3}{2} x+\frac{\sqrt 3}{2}x= 4(3+\sqrt 3)\\\\

\therefore \frac{(3+\sqrt 3)}{2} x= 4(3+\sqrt 3)\\\\

\therefore x = 4(3+\sqrt 3)\times \frac{2}{(3+\sqrt 3)}\\\\

\therefore x = 4\cancel{(3+\sqrt 3)}\times \frac{2}{\cancel {(3+\sqrt 3)}}\\\\

\therefore x = 4\times 2\\\\

\therefore x = 8\\\\

\huge\purple {\boxed{\implies MO = 8}} \: \\ [From\: equation \: (1)]\\\\

\because MP = \frac{1}{2} x \:

\\ [From\: equation \: (2)]\\\\

\therefore MP = \frac{1}{2} \times 8\\\\

Answer:

1202.5  miles

Step-by-step explanation:

It is given that.

A test of a new car shows it can drive 370 miles on 20 gallons of gas.

We need to find how far you could drive on 65 gallons of gas.

20 gallons of gas = 370 miles

1 gallon = 18.5 miles

For 65 gallons of gas, multiply 65 and 18.5.

65 gallons = 18.5 × 65 miles

= 1202.5  miles

Hence, 1202.5  miles you could drive on 65 gallons of the gas.

x+y = 87

1.5x+0.5y = 78.5

Step-by-step explanation:

Let x = number of nachos sold and y = number of sodas sold

x+y = 87 because that's the total number of nachos and sodas he sold

1.5x+0.5y = 78.5 because nachos cost $1.50 and sodas cost $0.50 and David made a total of $78.50

Answer:

590 centimeters

Step-by-step explanation:

Answer:

you have a line with slope = -1/3. A line perpendicular to that has to have slope that's the negative reciprocal, or 3.

So we have a slope and a point. The line in point-slope form is

(y-3) = 3(x-4).

You can convert that to another form if you need to

Answer:

x = 165°

Step-by-step explanation:

x° = 360 - (the measure of one interior angle of the octagon + the measure of one interior angle of the equilateral ∆)

Each interior angle of a regular octagon = 135° ([tex] \frac{(n - 2)180}{n} = 135°)

An equilateral ∆ has equal angles, each measuring 60°.

Therefore:

x° = 360° - (135° + 60°)

x = 360 - 195

x = 165°

Step-by-step explanation:

Let d = number of desktops.

Let a = number of laptops.

a + d = 165

a = d + 9

d = a - 9

a + d = 165

a + a - 9 = 165

2a - 9 = 165

2a = 174
