if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation
now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
Answer:
The scale for a model that is 30 inches long is 449.2 inches.
The scale for a model that is 2 feet long is 561.5 feet.
Step-by-step explanation:
Consider the provided information.
The USS Enterprise was 1,123 feet in length.
Part (A) What is the scale for a model that is 30 inches long?
1 feet = 12 inches.
First convert the length of USS enterprise in inches.
1×1,123 feet = 12×1,123 inches
1,123 feet = 13476 inches
Divide original length with the length of model.
The scale for the model is:
Hence, the scale for a model that is 30 inches long is 449.2 inches.
Part (B) What is the scale for a model that is 2 feet long?
Since, both the units are in feet, so simply divide original length with the length of model.
The scale for the model is:
Hence, the scale for a model that is 2 feet long is 561.5 feet.
Answer:
3x³+3x²+3x+8+
Step-by-step explanation:
You can use synthetic division for this problem since the divisor is in (x-a) form. The fraction is the remainder over the divisor.
