Hey there! I was looking at your question for a bit then realized you meant
, the imaginary number, not "1" at the end of each number.
- Complex numbers are numbers involving both real and imaginary numbers; thus, this question wouldn't make much sense without the imaginary number

The expression we are given is:

Open parenthesis and combine like terms:


This is answer choice B (assuming it's supposed to be an
and not a "1" at the end)
Let me know if you need any clarifications, thanks!

Answer:

Step-by-step explanation:
To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.
Area of the square.
To calculate the area of the square you have to calculate the square of one of its sides, following the formula:

Where "a" is the length of one of its side.
The side length of the square is a=7cm, so its area will be:

Area of the triangles.
The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.
To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:

The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:

Now that the area of all shape are calculated, you have to add them to determine the area of the logo:

Answer:
80m
Step-by-step explanation:
The height of giant redwood tree is 100m.
so half of it is 50m
The height of redwood tree is 30m+ 50m= 80m
Answer:
The samples are all drawn from the sample population. Is the not the characteristics of the sampling distribution of a sample statistic. The correct option is b.
Step-by-step explanation:
Samples are drawn from the population not from the sample population.
Therefore drawing samples from a sample population is not a characteristics of the sampling distribution of a sample statistic.
the domain is all the real numbers, or (-infinite <x<infinite)
the range is y>=-4
axis of symetry is x= -1
vertex is (-1,-4)
the parabola opens upwards
x intercepts (-3,0) and (1,0)
y intercepts (0,-3)
