( -3x )^0 / 2
if possible please explain
Hi
(-3x)^0/2
Simplify
= 1/2
I hope that's help !
Answer:
The length of P'Q' is 4 units
The length of P'R' is 3 units
Step-by-step explanation:
If you rotate the figure 180° then the vertex would be R, and from P to Q is 3 units left and 4 units down
To find the length of side P'Q' after rotating triangle PQR 180° about the origin, we need to find the distance between the points P'(0,0) and Q'. When you rotate a point (x, y) 180° about the origin, the new coordinates are (-x, -y). Using the distance formula, we can find the length of side P'Q': d = sqrt((-3-0)^2 + (-4-0)^2) = sqrt(9 + 16) = sqrt(25) = 5. Therefore, the length of side P'Q' is 5 units.
To find the length of side P'Q' after rotating triangle PQR 180° about the origin, we need to find the distance between the points P'(0,0) and Q'.
When you rotate a point (x, y) 180° about the origin, the new coordinates are (-x, -y).
So, the coordinates of point Q' would be (3, 4) rotated 180°, which is (-3, -4).
Using the distance formula, we can find the length of side P'Q':
d = sqrt((-3-0)^2 + (-4-0)^2) = sqrt(9 + 16) = sqrt(25) = 5.
Therefore, the length of side P'Q' is 5 units.

b.cross-pollination, by using parents that had different traits
c.self-pollination, by using one parent
d.random pollination, by using both identical- and different-trait matings
we know that
Gregor Mendal used a process of cross-pollination,by using parents that had different traits in his experiment with pea plants. He was studying the difference between tall and short pea plants, and how genes were expressed differently between the two, so this method of cross-pollination was vital in order to accurately recreate how this process would happen within nature.
therefore
the answer is the option
b.cross-pollination, by using parents that had different traits
