Answer:
f = - 324
Step-by-step explanation:
Given
= - 162
Multiply both sides by 2 to clear the fraction
f = 2 × - 162 = - 324
The answer is F because a common point is (0,-4)
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.
Answer:
(X+2) and (X-5)
Step-by-step explanation: (X+3)*x-3(X+3)-10
=(X*2+6X+9)-(3X+9)-10
=X*2+6X+9-3X-9-10
=X*2+3X-10
X=(-b+/-(b*2-4ac)*1/2)/2a
a=1, b=3, c=-10
=-3+/-((3)*x-4(1)9-10))*1/2/2(1)
=-3+/-(9+40)/2
=(-3+/-7)2
Therefore 1. (-3-7)/2, and 2. ((-3+7))/2
1. -10/2=-5, X=-5 therefore (X+5)
2. (4/2)=2, X=2 therefore (X-2)
