2. Determine whether segment AB is tangent to the given circle

Gemiola [76]

Answer:

Step-by-step explanation:

13² should be equal to 4² + 12² for that

checking, we get that 169 is not equal to 16+144= 160

so it's not right angle

to be tangent, it should be right angle

What is the value of a if va- vh is equals to 1

velikii [3]

Answer:

$\displaystyle a = \frac{1+vh}{v}$

Step-by-step explanation:

we want to figure out a value of a for the following condition

$\displaystyle va - vh = 1$

to do so factor out v;

$\displaystyle v (a - h )= 1$

divide both sides by v which yields:

$\displaystyle \frac{(a-h) \cancel{(v)}}{ \cancel{v}}= \frac{1}{v}$

therefore,

$\displaystyle a-h = { \frac{1}{v}}$

now,add h to both sides:

$\displaystyle a = \frac{1}{v}+h$

further simplification if necessary:

$\displaystyle a =\boxed{ \frac{1+vh}{v}}$

y = a(x – h)2 + k, where (h, k) is the vertex. in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.
