Answer:
![B' = (-3,6)](https://tex.z-dn.net/?f=B%27%20%3D%20%28-3%2C6%29)
Step-by-step explanation:
Given
![A(4,5)](https://tex.z-dn.net/?f=A%284%2C5%29)
![B(0,5)](https://tex.z-dn.net/?f=B%280%2C5%29)
![C(3,-1)](https://tex.z-dn.net/?f=C%283%2C-1%29)
<em>Translation: 3 units left and 1 unit right</em>
Required
Determine the new coordinates of B
Write out the coordinates of B
![x = 0](https://tex.z-dn.net/?f=x%20%3D%200)
![y = 5](https://tex.z-dn.net/?f=y%20%3D%205)
When a function is shifted to the left, we have to subtract the unit from the x value of the function;
<em>Shifting by 3 units left, the new x becomes </em>
<em />
<em />
<em />
<em />
<em />
When a function is shifted upward, we have to add the unit to the y value of the function;
<em>Shifting by 1 unit up, the new y becomes </em>
![New\ y = 5 + 1](https://tex.z-dn.net/?f=New%5C%20y%20%3D%205%20%2B%201)
![New\ y = 6](https://tex.z-dn.net/?f=New%5C%20y%20%3D%206)
Hence, the new coordinates of B is
![B' = (-3,6)](https://tex.z-dn.net/?f=B%27%20%3D%20%28-3%2C6%29)
Answer:
<h2>
m∠a = 67° , m∠b = 42°</h2>
Step-by-step explanation:
∠a is alternate interior angle to ∠ECD
∠b is alternate interior angle to ∠BCD
so:
If AB || CD then:
m∠a = m∠ECD = 25° + 42° = 67°
m∠b = 42°
It shows a change in growth, and has a percentage rate that is positive, I .
Answer:
B: Yes, the participants are grouped by sun exposure, and then both treatments are randomly assigned within each group.
Step-by-step explanation:
Randomized block design is one in which the experimental units are categorized into groups which we call blocks. Thereafter, treatments will be randomly allocated to the experimental units inside each of the blocks.
Now, from the question, we can see that they were grouped in Blocks according to their outdoor activity which is degree of exposure to the sun. Thereafter the individual groups are randomly assigned treatments.
Thus, Option B is correct.
