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
Answer:
<D = 82°
<E = 49°
<F = 49°
Step-by-step explanation:
This is an isosceles triangle because two of the sides are the same length which means the 2 bottom angles are the exact same which means we can set them equal to each other to solve for it.
Answer:
8 and 1/4
Step-by-step explanation:
10 3/4 - 2 1/2
3/4 - 1/2 = 1/4
10 - 2 = 8
The two equations represent the proportional relationship.
y=3x and y=12x are proportional relation ship equations
proportion equations can be defined as
If we change x the y will change in the same proportion.
<h3>What is the proportional relationship?</h3>
Proportional relationships are relationships between two variables where their ratios are equivalent.
Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.
That constant is known as the constant of proportionality.
proportional relationship equation contain (0,0) points
If we put x=0
This will give us,y=0
If we put x=0, in y=12x
It will give y=0
put if we put x=0 in
y=3x it will give us y=0
hence these two equations represent the proportional relationship.
