Mathematics
1 answer:
Readme [11.4K]3 years ago
3 0

Answer:

\sqrt{75}

Step-by-step explanation:

If it was actually square-rooted, it would be 8.660254038, but that is not the simplest form. Therefore, the simplest from of the square root of 75 is the square root of 75 itself, which is \sqrt{75}. Hope this helped!

Cual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2
drek231 [11]

Respuesta:

175 rad / s²

Explicación paso a paso:

Dado que :

Velocidad angular final = 350 rad / s

Tiempo empleado = 2 segundos

La aceleración angular, a =?

Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo

(velocidad final - Velocidad inicial) / tiempo empleado

Velocidad inicial = 0 rad / s

Aceleración angular = (350 - 0) / 2 = 350/2

= 175 rad / s²

Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite th
Advocard [28]

Answer:

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

Step-by-step explanation:

<u>Let's convert the standard equation into slope-intercept form:</u>

  • Ax + By = C              ⇒ subtract Ax from both sides
  • By = -Ax + C             ⇒ divide both sides by B
  • y = -A/Bx + C/B        ⇒ converted to slope- intercept form

As we see the slope is -A/B

<u>The equation 7x + 9y = 14 is converted as:</u>

  • y = -7/9x + 14/9, where the slope is -7/9

<u>Looking at the answer options and the correct one is option B, where both identification of slopes match.</u>

  • B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

What are the solutions to the system of equations?
svet-max [94.6K]

Answer:the third option is correct

Step-by-step explanation:

The system of equations are

y = 2x^2 - 5x - 7 - - - - - - - - - - -1

y = 2x + 2 - - - - - - - - - - - - - 2

We would equate equation 1 and equation 2. It becomes

2x^2 - 5x - 7 = 2x + 2

2x^2 - 5x - 2x - 7 - 2 = 0

2x^2 - 7x - 9 = 0

We would find two numbers such that their sum or difference is -7x and their product is - 18x^2. The two numbers are 2x and - 9x. Therefore

2x^2 + 2x - 9x - 9 = 0

2x(x + 1) - 9(x + 1) = 0

2x - 9 = 0 or x + 1 = 0

2x = 9 or x = - 1

x = 9/2 = 4.5

Substituting x = 4.5 or x = -1 into equation 2, it becomes

y = 2 × 4.5 + 2 or y = 2 × - 1 + 2

y = 11 or y = 0

Therefore, the solutions are

(4.5, 11) (- 1, 0)

What are all solutions to the differential equation dy/dx=sec^2*x ?
zysi [14]

Answer:

y=tanx+C

Step-by-step explanation:

\frac{dy}{dx}  =  {sec}^{2}  \: x \\  \\ dy = {sec}^{2}  \: x \: dx \\  integrating \: both \: sides \\  \\  \int \:1\: dy =  \int {sec}^{2}  \: x \: dx \\  \\  \huge \red{ \boxed{ \therefore \: y = tan \: x + c}} \\
