The given equation of parabola is
Which can also be written as
Here vertex (h,k) is (1,2)
And value of a is
Formula of focus is
Substituting the values of h,k and a, we will get
Therefore the correct option is the last option .
Answer: k = 12
<u>Step-by-step explanation:</u>
x² + kx + 36 = 0
In order for x to have exactly one solution, it must be a perfect square.
(x + √36)² = 0
(x + 6)² = 0
(x + 6)(x + 6) = 0
x² + 6x + 6x + 36 = 0
x² + 12x + 36 = 0
k = 12
Answer:
Mi=chael cut out 65% of the shapes. He cut out 32 shapes. How many shapes does Michael need to cut out altogether?
65x/100= 32

Hello
f(x) · g(x) = f·g(x) = (log x)(5x-2) = 5x(logx) -2logx
I changed log base 10 to just log for simplicity.
Have a nice day :D
