To solve for R you use PEMDAS
Answer:
Step-by-step explanation:
When dividing numbers with powers, it is handy to remember that
so
256-192= 64
192-144=48
144-108=36
108-81=27
81- 60.8=20.2
60.8-45.6=15.2
45.6-34.2= 11.4
34.2-25.6=8.6
25.6-19.2= 6.4
19.2-14.4= 4.8
Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.
Answer:
1) vertex:-1
axis of symmetry:-1
y-intercept (0,-10)
x-intercepts (-3.449, 0) and (1.449, 0)
2) vertex: -1
axis of symmetry: -1
y-intercept (0,-15)
x-intercepts (3, 0) and (-5, 0)
