Answer:
See below.
Step-by-step explanation:
This is the number of permutations of 7 from 48.
= 48! / (48-7)!
= 48! / 41!
= 3.71090523 * 10^11.
First, express the mixed numbers as simple fractions:
1 3/5 = (1x5+3)/5 = 8/5
1 9/10= (10x1+9)/10 = 19/10
Add both:
The sum is greater than 3 and less than 4.
Answer:
P(x) = - 5(x + 2)²(x - 3)
Step-by-step explanation:
Given roots x = - 2 with multiplicity 2 and x = 3 , then the factors are
(x + 2)² and (x - 3)
P(x) is then the product of the factors, that is
P(x) = a(x + 2)²(x - 3) ← a is a multiplier
To find a substitute (2, 80) into P(x)
80 = a(2 + 2)²(2 - 3) = a(16)(- 1) = - 16a ( divide both sides by - 16 )
a = - 5
P(x) = - 5(x + 2)²(x - 3)
Answer:
y = 3/2 when x = 15
Step-by-step explanation:
y = k / √1+x
2 = k / √1+8 = k/3
k = 6
y' = 6 / √1+15 = 6/4 = 3/2
