Can someone please help me out :))
ki77a [65]

Answer:

sin(T)

cos(C)

Step-by-step explanation:

sine goes up or down for angles in the circle.

cosine goes left or right for angles in the circle.

consider a circle with is center at T, and it goes through C (so, the radius is 25 = TC).

then 7 = sin(T)×25

24 = cos(T)×25

so, sin(T) = 7/25

then, sin(T) = cos(90-T)

and the angle at C = 90-T.

therefore, cos(C)=sin(T)=7/25

tan(x) = sin(x)/cos(x)

and that would lead here always to a 7/24 or 24/7 ratio.

so, no tan function is right.

Find the second derivative y=1/5x^2+1/11x
Amiraneli [1.4K]

\frac{dy}{dx}=\frac{1}{5}.x^{2-1}.2 + \frac{1}{11}.x^{1-1}.1

\frac{dy}{dx}=\frac{2}{5}.x+\frac{1}{11}

\frac{d^2y}{dx^2}=\frac{2}{5}.x^{1-1}.1

\frac{d^2y}{dx^2}=\frac{2}{5}

How many solutions are in 6x+30+4x=10(x+3)
Jobisdone [24]

First, let's simplify the equation.

6x + 30 + 4x = 10(x + 3)

  • Set up

10x + 30 = 10(x + 3)

  • Combine like terms

10x + 30 = 10x + 30

  • Apply the Distributive Property to the right hand side of the equation

30 = 30

  • Subtract 10x from both sides of the equation

Since the right and left sides of the equation are equal, we know that there must be an infinite number of solutions. This means that there is an infinite amount of values that we can substitute for x for the equation to be true.
