Easy,
23y-(7x-2y)+x
<span>There is an imaginary</span> 1 in front of the parentheses, making it,
23y-1(7x-2y)+x
Now, distribute the 1.
-1*7x= -7x
and
-1*-2y= 2y
Leaving your problem looking like...
23y-7x+2y+x
Combine your apples and oranges.....
25y-6x
Thus, your answer.
Answer:
+4,000 / 28,573,199 = [45]
Step-by-step explanation:
<h2>Given :-</h2>
Initial speed (v) = 1.9m/s
Final speed (u) = 3.8m/s
Time (t) = 11 s
<h2>Formula Used :-</h2>
(a = acceleration)
➾ 
<h2>Solution:-</h2>
(putting the value of v, u and t from above)
➾ 
➾ 
➾ 
Therefore, the acceleration rate = 0.17m/s.
Answer:
Time t = 1.39 seconds
Step-by-step explanation:
Given;
Initial velocity v = 20 ft/sec
height equation;
h = -16t^2 + 20t + 6
How long does it take for the disc to be caught 3 feet off the ground;
At this point h = 3
Substituting h = 3 into the height equation;
3 = -16t^2 + 20t + 6
-16t^2 + 20t + 6 - 3 = 0
-16t^2 + 20t + 3 = 0
Solving the quadratic equation;
t = 1.39 or t = -0.14
Since t cannot be negative;
Time t = 1.39 seconds
