Answer:
: 4qrs • (qr2 + 2)
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((22q2 • r3) • s) + 8qrs
Pulling out like terms :
3.1 Pull out like factors :
4q2r3s + 8qrs = 4qrs • (qr2 + 2)
Final result :
4qrs • (qr2 + 2)
I am really soo sorry if the answer is wrong!
The area under the speed curve tells you how much distance the vehicle covers.
The distance for first 30 s corresponds to the area of a rectangle with height <em>k</em> m/s and length 30 s, or
(<em>k</em> m/s) (30 s) = 30<em>k</em> m
The distance for the last 20 s corresponds to the area of triangle with height <em>k</em> m/s and length 20 s, or
1/2 (<em>k</em> m/s) (20 s) = 10<em>k</em> m
If the total distance traveled was 1.7 km = 1700 m, then
30<em>k</em> + 10<em>k</em> = 1700
40<em>k</em> = 1700
<em>k</em> = 42.5
Answer:
i think the second question (the choose the Function) means choose the function that has changed the most.
the first choose function one, i dont know but... according to wikipedia, "an initial value problem is an ordinary differential equation together with an initial condition which specifies the value of the unknown function at a given point in the domain. Modeling a system in physics or other sciences frequently amounts to solving an initial value problem." hope this helps
