Answer:
-1.5y
Step-by-step explanation:
+y(–1.5) = -1.5y
This is how distribution works
To solve this problem you must apply the proccedure shown below:
1. You have:
<span>
In(2x+3)=7
2. Then, you must apply log(e), as below:
</span><span>
In(2x+3)=ln(e^7)
3. Now, you obtain:
2x+3=e^7
4. Youy must clear the variable "x", as below:
2x=e^7-3
</span> x=(e^7-3)/2
<span>
5. Therefore, the value of "x" is:
x=546.817
</span><span>
The answer is: </span>x=546.817<span> </span>
One way is to factor it
trial and error, with experience
(3x+5)(x-2)
answer is C

Answer:
-101 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relevant relation is ...
Tan = Opposite/Adjacent
Opposite = Adjacent × Tan
height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft
__
The usual relation between estimates and errors is ...
error = estimate - actual
Then ...
actual = estimate - error
For the given angle and error, the actual angle is ...
actual angle = 47° -(-1°) = 48°
actual height = (2640 ft)·tan(48°) ≈ 2932 ft
Then the change in the height of the mountain due to the error is ...
2831 ft -2932 ft = -101 ft
The error of -1° in angle estimate creates an error of -101 ft in the height estimate.
I hope this is the way it must be calculated
