It would be 200Km/Hr, 1.5=3/2, or three halves, 300 can be divided by three to get 100, making it 100 per half hour, and since car speeds are to the hour, you double that to get 200 per hour.
It could be either, we need more info. How big are each? If it doesn't say, then it's a trick question. Throw Schrodinger's cat at it or something.
Answer:
Degree = 4
Step-by-step explanation:
For the given conditions:
n = 4
i and 5i are zeros
f(-2) = 145
For zeros, it means they are a quadratic factor of the expression
It means, we will have x = ± i and x = ± 5i
therefore, the given factors are (x - i)(x + i)(x - 5i)(x + 5i)
Hence, we have the function
given degree = 4
f(x) = a(x-i)(x+i)(x-5i)(x+5i)
f(x) = a(x² + 1)(x² + 25)
Hence, substituting -2 for x, we have
f(-2) = a(5)(29) = 145
Hence, a = 1
f(x) = x⁴ + 26x² + 25
Therefore, we can see that the given degree = 4
First we need to define this equation using point slope form.
Point slope form is represented by the following (x₁ and y₁ represent the given points, and m represents slope)

So if we plug in our values, we get

Now, in order to get it into slope-intercept form, we must isolate the Y value

So the equation is
Y = X-7
