Answer:
Step-by-step explanation:
To express the radical 
using the imaginary unit, we apply the following:
Since we can express the root of two product as a product of their roots:
Answer:
Step-by-step explanation:
Let number be x and y
x+y=56.........eqn(I)
x-y=4..............eqn(ii)
x=4+y.........eqn(iii)
Substitute eqn (iii)&(I)
You get y=26
From eqn(iii)
You get x=30
A carpenter's square is a ruler which looks like a right triangle. Being such, it has a long side and a short side. Assuming that the radius of each wheel is the size of the short side, we can use this to measure the mid point of the wheel. The mid point of the wheel is the optimal point where you can bore a hole.
Answer:
See below
Step-by-step explanation:
For the domain in question 8, it is observable that the graph is continuously expanding to the right and left. This means that the domain is (-∞, ∞).
For the range in question 9, the y-values include -2 and continue to go up. Therefore the range would be [-2, ∞)
For the domain in question 10, the x-values span from -2, the leftmost(inclusive), to 2, the rightmost(inclusive), without any breaks. This means the domain is [-2, 2]
For the range in question 10, the y-values span from the uppermost value of 3 to the lowest of -3(inclusive) without any breaks. This means that they ranage is [-3, 3]
