Answer:
,
Step-by-step explanation:
The function of the graph can be written in the vertex form as
, where V(h,k)=V(2,4) is the vertex of the quadratic function.
We substitute the value to obtain;
,
The point (5,1) lies on the graph so we use it to determine the value of a.
,
,
,
The required equation is
,
Answer:
The result for this equation is .
Step-by-step explanation:
-Solve:
-Multiply and
by
:
-Reduce to the lowest term by extracting and canceling out 3:
-So, the result is .
if the degrees in this triangle are truly 90-45-45, then the two unknown lengths are the same
and the pythagorean theorem holds anyways: a² + b² = c², where c is the longest side in a right triangle.
c is 16, so 16² is 256
2* a² = 256
I wrote 2 times s because a and b are of same length
devide each side by 2
a² = 128
take the root
a and b are:
