The answer is 100 pi in the question but in cm...is 314cm^2
<span>arctan(2x) = -1 radian
</span>⇒ 2x = tan(-1)
⇒ 2x = -1.5574
⇒ x = -1.5574/2
⇒ x = - 0.7787<span>

Answer: see below...
Step-by-step explanation:
a)
48 = 30%
100/30 = 10/3
48 x (10/3) = 160
$160 = 100%
b)
160 - 48 = $112
Answer:
6 F
Step-by-step explanation:
We want to find the temperature difference
Given that the initial temperature read minus 17 F
And the new temperature is increased by 23 F
The new temperature is
=-17+23= 6 F
Therefore the new temperature is 6F
