Answer:
x= 3.096
Step-by-step explanation:
divide both sides by 5: 3^(x-1)= 10
then take the log to get log_3 (10) = x-1 = 2.096
x= 3.096
Answer: 2.9 ≠ −7 (False)
Step-by-step explanation:
Answer:
y = 189.8
Step-by-step explanation:
Apply trigonometric function to find y.
Reference angle (θ) = 50°
Adjacent side = 122
Hypotenuse = y
Apply CAH, since the Hypotenuse and the Adjacent are involved.
Thus:
Cos θ = Adj/Hypo
Plug in the values
Cos 50° = 122/y
y*Cos 50° = 122
y = 122/cos 50°
y = 189.8 (beater tenth)
Answer:
2. Weather forecasts are difficult to trust
Step-by-step explanation:
Words like thus are preliminar to a conclusion, that is, we use words like thus when we are going to conclude something.
For Example:
The New Englard Patriots have won 6 Super Bowls. Thus, the New England Patriots are a good NFL franchise.
The conclusion is that the Patriots are a good NFL franchise.
In this problem, we have that:
Thus, it is difficult to trust weather forecasts.
The conclusion is:
2. Weather forecasts are difficult to trust
2.125*10^4 x 10^4 / 1.25 x 10^3
= (2.125 / 1.25) x 10^(4 - 3)
= 1.7 x 10^1
= 17
Answer
17 times greater
