Answer:
2 imaginary roots
Step-by-step explanation:
The discriminate is the portion of the quadratic equation under the square root
D = b^2 - 4ac
D = 8^2 - 4(2)(16)
D = 64 - 128
D = -64
Since the discriminate is negative the square root will be imaginary
and there will be 2 of them
2 imaginary roots
Answer:
66.4 in^2
Step-by-step explanation:
Surface area is defined as the area around the surface of a 3-dimensional solid. The shape we are given here is a triangular prism with a square base. This means it contains one square and 4 triangles on the surface. To find the surface area, we just need to find the areas of all 5 surface shapes and add them up. We have been given that the square has a side length of 4 inches, meaning the area is 4^2 or 16. The area of a triangle is (1/2)base*height. The base length is 4 inches and the height is 6.3, and (1/2)*4*6.3 is 12.6. Note that, since there are four triangles, we have to multiply this value by 4 (12.6*4 = 50.4). Now we have the area of the square and the area of all the triangles put together, so we can just add them up:
16 + 50.4 = 66.4
Angle WVX = Angle YVZ (vertically opposite angles)
Angle VWX = Angle VYZ (shown)
Angle WXV = Angle YZV (total sum of angles in triangle)
Answer:
9.193259%
Step-by-step explanation:
In order to obtain the percentage of military members in the reserves who are Black, we will have to multiply the percentage of Black military members in the reserve by the percentage of military members in the reserve. This is calculated as follows:
Military members in the reserves who are Black (%) = 77.1771% × 11.9119%
= 9.193259%
Therefore, he percentage of military members in the reserves who are Black is 9.193259%
.
Example
For example, let assume the total number of active members in the military is 100.
To obtain the number of military members who are in the reserves, we multiply 77.1771% by 100. This gives us 78 approximately.
To obtain the number of military members in the reserves who are Black, we multiply 11.9119% by 78 we got above who are active military members in the reserves. This gives us 9 members approximately.
I wish you the best.
The answer would be 1/4 or
i hope this answer helps!
