Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.

Answer:
9
Step-by-step explanation:
8 times 9 is 72
80 times 9 is 720
720 divided by 9 is 80
We have 4 rectangles 10 * 25 and 2 rectangles 10*10
so surface area of the bos will be 4*250 + 2*100 = 1200 cm^3
