Answer:
2.5
Step-by-step explanation:
Answer:
Brad average typing rate in words per minute is 21
1260 divided by 60 = 21
(In case you meant 30 minutes)
1260 divided by 30 = 42
Step-by-step explanation:
In a typing class, the average number N of words per minute typed after t weeks of lessons is
N=157/(1+5.4e^-0.12t)
N=157/(1+5.4e
−
0.12t)
. Find the time necessary to type 75 words per minute
Answer:
24 root 6
Step-by-step explanation:
Answer:
(x2 - 1) - 5x - 1
Step-by-step explanation:
Answer: (-5/2,0) is the other x intercept.
Step-by-step explanation:
Make use of given fact that (x - 1/2) is a factor of the polynomial.
Divide 4x^2 + 8x - 5 by (x - 1/2)
Partial quotient 4x.
Subtract 4x × (x - 1/2) = 4x^2 - 2x from dividend giving 10x - 5 remainder.
Second partial quotient is 10,
10 × (x - 1/2) = 10x - 5, remainder zero
(x - 1/2)(4x + 10) = 4x^2 + 8x - 5
Graph of the parabola crosses the x axis where 4x+10=0, x = -5/2.
