<u>Answer: </u>
is scientific notation of given number 17210000000.
<u>Solution: </u>
Given number which needs to be converted into scientific notation is 17210000000.
Scientific notation is standard way of representing very large number or very small number.
In scientific notation, decimal comes after first digit and multiply to power of 10 dependency on total digits of number.
In our case, given number is 17210000000.
So we need decimal after first and after that number of digits are 10.
So 17210000000 =
Hence is scientific notation of given number 17210000000.
Answer:
vertex = (- 1, - 4 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = -
y = x² + 2x - 3 ← is in standard form
with a = 1, b = 2 , then
x = - = - 1
Substitute x = - 1 into the equation for corresponding value of y
y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4
vertex = (- 1, - 4 )
