Cos(t)=24/25, what does sin(t)=?

Mathematics

kozerog [31]3 years ago

Answer:

The value of sin t is \frac{7}{25}

Step-by-step explanation:

Given as :

cos (t) = \frac{24}{25}

Since sin² t + cos² t = 1

So, sin² t = 1 - cos² t

or,  sin² t = 1 - (\frac{24}{25})²

or,  sin² t = \frac{25^{2} - 24^{2} }{25^{2} }

Or,  sin² t = \frac{625 - 576}{625}

Or ,   sin² t = \frac{49}{625}

Or, sin t = \sqrt{\frac{49}{625} }

So, sin t = \frac{7}{25}

Hence The value of sin t is \frac{7}{25}   Answer

Hey how do you get from standard form to vertex form?
vlabodo [156]

Explanation:

Conversion of a quadratic equation from standard form to vertex form is done by completing the square method.

Assume the quadratic equation to be \mathbf{ax^{2}+bx+c=0} where x is the variable.

Completing the square method is as follows:

  1. send the constant term to other side of equal                 \mathbf{ax^{2}+bx=-c}
  2. divide the whole equation be coefficient of \mathbf{x^{2}}, this will give     \mathbf{x^{2}+\frac{b}{a}x=- \frac{c}{a}}
  3. add \mathbf{(\frac{b}{2a})^{2}} to both side of equality                                   \mathbf{x^{2}+2\times\frac{b}{2a}x+\frac{b}{2a}^{2}=-\frac{c}{a}+\frac{b}{2a}^{2}}
  4. Make one fraction on the right side and compress the expression on the left side                                                                          \mathbf{(x+\frac{b}{2a})^{2}=\frac{b^{2}-4ac}{4a^{2}}}
  5. rearrange the terms will give the vertex form of standard quadratic equation                                                                 \mathbf{a(x+\frac{b}{2a})^{2}-\frac{b^{2}-4ac}{4a}=0}

Follow the above procedure will give the vertex form.

(NOTE : you must know that \mathbf{(x+a)^{2}=x^{2}+2ax+a^{2}}. Use this equation in transforming the equation from step 3 to step 4)

salantis [7]
This is a two step word problem so first your gonna have to subtract 320-50= 270 then divide to find your final answer so 270 divided by 8 is 33.75

Charra [1.4K]

9514 1404 393

Answer:

  14.  C

  15.  C

Step-by-step explanation:

14. The function is entirely in quadrants I and II, so the leading coefficient is positive. This eliminates choices A and B.

The horizontal asymptote is 0, not -1, eliminating choice D.

The curve is best described by the equation of choice C.

__

15. The domain and range of an unadulterated exponential function are ...

  domain: all real numbers; range: y > 0 . . . . matches choice C
