What is the value of k?
Romashka-Z-Leto [24]

Answer:

k = 10

Step-by-step explanation:

The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.  

So 10k + 15 must equal the remaining 115

subtract 15 from each side and you get 10k = 100

divide each each by 10 and you get the answer of k = 10

What is the vertex of the quadratic function f(x)=(x-8)(x-2)?
7nadin3 [17]
Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)

another way to do it: 
f(x)=x²-10x+16
the vertex is when x=-\frac{b}{2a}, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
