Answer:
x = - 2 or x = 4
Step-by-step explanation:
the expression inside the absolute value can be positive or negative
Removing the bars and solve x - 1 = ± 3
x - 1 = - 3 or x - 1 = 3
x - 1 = - 3 ( add 1 to both sides ) ⇒ x = - 2
x - 1 = 3 ( add 1 to both sides ) ⇒ x = 4
Answer:
36
Step-by-step explanation:



To solve this problem you must apply the proccedure shown below:
1. You have that the forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9√t<span> acres per hour. Therefore, you have:
</span>
1600+∫(9√t)dt (from 0 to 16)
2. Then, when you solve it, you obtain:
1600+6t^3/2=1984
3. Therefore, as you can see, the answer is: 1984 acres.
S is equal to 140. This is because the smallest angle is 60 degrees. The biggest angle is 160 degrees. And 60 + 160 = 220. A circle is 360 degrees. 360 minus 220 equals 140.
