Hello :
the slope of tangent in A(x':y') is : f'(x') =3
f'(x) = 2x-5
2x'-3 =3
2x' = 6
x' = 3
f(3)= 3²-5(3)+7=1
1 =3(3)+c
c =-8
This is 1/2)2=1/4 hope this helps
Answer:
Press A takes 10 hours to do a certain job. So Press A does (1/10)th of the job in an hour.
Press A and Press B, together do (1/2.5) or (4/10)th of the job in an hour.
So Press B does (4/10)-(1/10) = (3/10)th of the job in an hour. So Press B can do the job in (10/3) hours or 3 hour and 20 mins.
Check: A does (1/10)th and B does (3/10)th part of the job in an hour. A and B together will take (1/10)+(3/10) = 4/10th of the job in an hour. So they will complete the job in 10/4 = 2.5 hours. Correct.
Answer: Press B can do the job in 3 hour and 20 mins.
Step-by-step explanation:
First solve the equation by dividing 5 on both sides...
Y = 5\2x + 2
Now we want perpendicular and the line to flip across the axis so the answer is....
Y = -2\5 + 2
Answer:
21300
Step-by-step explanation:
3 keeps 50 the same, and if the number is below 4 then the number stays the same, if it's 5 and up the number goes up by one digit.
