Write each trigonometric ratio as a fraction in simplest form. show all supporting work
Nesterboy [21]

Answer: \frac{x}{20}

Step-by-step explanation:

Sine uses the ratio,  \frac{opposite}{hypotenuse} so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

sinA=\frac{x}{20}

You can't reduce this any further because there is an unknown variable.

I am not sure how to slove
notsponge [240]

First .... the limit of the given function is NOT EQUAL to 5 (it diverges so it has no limit).  There is a typo.  The 14 should be positive.

\lim_{x \to\ 7} \bigg(\dfrac{x^2-9x+14}{x-7}\bigg)=5

The precise definition of a limit is:

\text{If for every } \epsilon>0\text{ there exists a }\delta >0\text{ such that}\\|f(x)-L|

Given:

f(x) = \dfrac{x^2-9x+14}{x-7}\\\\L=5\\\\a=7\\\\\\|f(x)-L|

⇒ \epsilon = \delta

When ε = 0.1,     δ = 0.1

When ε = 0.01,   δ = 0.01
