Answer:
i
Step-by-step explanation:
Why is i the square root of negative one?
The term "imaginary" is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero, which has one double square root.
I don’t under stand that but I think it’s 4
Answer:
The height of the building is approximately <u>73 m</u>.
Step-by-step explanation:
The triangle EFG is shown below.
Given:
Length of shadow of building is, 
Angle of inclination of Sun with the vertical is 25°.
Therefore, the angle of inclination of Sun with the horizontal is given as:

Now, in triangle EFG as shown below, we use the tangent ratio to determine the height of building EF. Therefore,

Therefore, the height of the building is approximately 73 m.
Answer: 30t + 30m ≤ 330
Step-by-step explanation:
The maximum amount of pounds the truck can carry is 330 pounds so whatever will be carried has to either be equal to or less than 330 pounds.
= ≤ 330
t represents the number of bags of top soil and m represents the number of bags of mulch.
Each bag of top soil is 30 pounds and each bag of mulch is 30 pounds as well.
= 30t + 30m
Put together;
30t + 30m ≤ 330
