Answer:
Graph (2), top right.
Step-by-step explanation:
Given function is f(x) = x² + 2x - 1
f(x) = x² + 2x + 1 - 2
f(x) = (x + 1)² - 2
From this standard equation of a parabola,
Vertex → (-1, -2)
Axis of symmetry → x = (-1)
y-intercept → y = (-1)
Since coefficient of maximum degree term (x²) is positive so, parabola is opening upwards.
From the given choices, second option (top row right) is the answer.
Answer:21943.812
Step-by-step explanation: make sure you put you highest valuable number on top to make it easier then work from right to left and multiply by the bottom number in each Column with the top and make sure to carry when needed
The answer is A. I got this answer by crossing out the possibilities. 90 degrees and 60 degrees are too short and 180 degrees is too long.
I think it is meant to say 5 cm. Otherwise it won't work.
So 135/(5*36) = 0.75cm
