Answer:

The answer is B.

Step-by-step explanation:

As the sum of interior angles in a triangle is 180deg.

<C = 180-110-45 = 25deg.

Using sine rule, a/sinA = b/sinB = c/sinC

a=7*sin45deg/sin25deg = 11.71

b=7*sin110deg/sin25deg = 15.56

The answer is B.

explain why the function f(x)= 5x-15/x-3 is not asymptotic to the line x=3. sketch the graph of this function.
Katyanochek1 [597]
X=3 is a vertical line . The question is "Is this line a vertical asymptotefor the function f(x)?". Vertical asymptote is vertical line near which the function grows without bound.
The function f(x)=5x-15/x-3 is not asymptotic to the line x=3, because for x=3 f(x)=5*3-15/3-3=0/0=0 . So, there is a value for x=3 and the function f(x) does not grow near x=3 without bound.

What are the coordinates of J'?
attashe74 [19]

Answer:

F'(-\frac{10}{3},-\frac{8}{3})

or

F'(-3.33,-2.67)

Step-by-step explanation:

we know that

The coordinates of point F are (-5,-4) (see the figure)

In this problem

A dilation with a scale factor 2/3 about the origin is described using the following notation:

(x,y) ----> (\frac{2}{3}x,\frac{2}{3}y)

so

Applying the rule of the dilation to point F

F(-5,-4) ----> F'(\frac{2}{3}(-5),\frac{2}{3}(-4))

F(-5,-4) ----> F'(-\frac{10}{3},-\frac{8}{3})

F(-5,-4) ----> F'(-3.33,-2.67)
