To simplify 4/(2+7i), we multiply it by a fraction equal to one that removes the i value in the denominator. The best value to do this is the complex conjugate divided by itself, so we have 4(2-7i)/((2+7i)(2-7i)). Simplifying, we have (8-28i)/(4-(-49))=(8-28i)/53, which is a completely simplified fraction since 8 and 53 are relatively prime (or coprime), and there are no radicals in the denominator.
Resolving a function of any nature means determining your zeros or raizes.
The zeros of a function occur when the function is null.
Then:
f(x) = 3x - 2
To determine the root
f(x) = 0 = 3x - 2
3x = 2
x = 2/3 Final result
Answer:
85° and 95°
Step-by-step explanation:
A linear pair of angles sum to 180° , then
3x + 10 + 4x - 5 = 180
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Then
3x + 10 = 3(25) + 10 = 75 + 10 = 85°
4x - 5 = 4(25) - 5 = 100 - 5 = 95°
Answer:
c. diameter
because when a line intersects the center and even touches the centre is called a diameter
hope it helps.
Answer:
15 meters
Step-by-step explanation:
One side is 2.5 meters, so if they're all the same then you would multiply that by 6
