Answer:
hello!
Step-by-step explanation:
Sory but...I can't be able to answer the answer since u r being specific
So Dylan traveled a total of
100 meters (to the neighbors house)
plus 1.5 kilometers which a kilometer means thousand meters so its really 1500 meters
plus 310 meters
For Dylans distance we can do 100 + 1500 + 310 = 1910
Specers distance is given which is 1269
To find the final answer we can do Dylans distance minus Spencers so 1910 - 1269 which equals 641.
The correct answer would be that Dylan traveled 641 meters farther than Spencer
Answer: 641
Hope this helps!
Answer:
D is correct. 
Step-by-step explanation:
We are given the root of the equation

If we are given solution of the equation then find equation using formula.
If a and b are the solution of equation then equation would be (x-a)(x-b)=0
Here, 
Equation form would be 
Now we simplify the above equation to get correct option.


So, D is correct. 
The balloon has a volume
dependent on its radius
:

Differentiating with respect to time
gives

If the volume is increasing at a rate of 10 cubic m/s, then at the moment the radius is 3 m, it is increasing at a rate of

The surface area of the balloon is

and differentiating gives

so that at the moment the radius is 3 m, its area is increasing at a rate of
