This situation calls for an observational study. Unfortunately, cardiovascular health is difficult to measure unless one defines some "health scale" so that health could be roughly quantitized.
Answer:
x =2.8074
Step-by-step explanation:
2^x = 7
Take the log of each side
log (2^x) = log (7)
We know log a^b = b log a
x log 2 = log 7
x = log (7) / log 2
x =2.80735
To the nearest tenth thousandth
x =2.8074
Answer:
(x - 3) is a factor of the given function
Step-by-step explanation:
Given function:
If (x - 3) is a factor of the given function then 
Substitute x = 3 into the function and solve:
Therefore, as then (x - 3) is a factor of the given function.
Answer:
-4a -14
Step-by-step explanation:
(−2) ∙ (2a+7)
Distribute
-2 * 2a + -2*7
-4a -14
