Answer:
4.58
Step-by-step explanation:
Using the formula
a^2=(c^2)-(b^2)
a^2=(5^2)-(2^2)
a^2=25-4
a^2=21
Using Square root on Both Sides
a=4.58
Answer:
f(x) = x^2 (x + 7i)(x - 7i)
Step-by-step explanation:
Factoring out x^2 gives ...
f(x) = x^2(x^2 +49)
The factor with 49 can be considered to be the difference of two squares, where one of the squares is -49. Then its square root is ±7i, and the factorization of that term is ...
x^2 +49 = (x +7i)(x -7i)
So, the overall factorization of f(x) is ...
f(x) = x^2(x +7i)(x -7i)
The domain of the first one is -3,-1,0,2,7. The range is -7,-3,-1,3,7.
For the second, the domain is -5,-4,0,1,2. The range is -4,2,2,3,4.
Domain is just the x-values
Range is just the y-values
Answer:
Step-by-step explanation:
Slope = y/x
y1-y2/x1-x2=slope of 2 points
8-3/-6-2 = 5/-8 which equals -5/8 or -.625.
