Answer:
Natural numbers
Step-by-step explanation:
Rational numbers are numbers which can be expressed in the form a/b ; such that b ≠ 0 ; hence, rational numbers can be certain non-recurring decimal values.
Integer values are numbers which can be written without any fractional component. While natural numbers are characterized as being whole and non-negative
To represent population values, number of people or species cannot be fractional and cannot be negative, hence natural numbers is the best option.
Answer:
L = 34 - 0.5d
21 feet
Step-by-step explanation:
The initial water level ; 34
the amount is rises per day; 0.5
"L" is the water level,
"d" is the days passed.
In order to find the water level, one will have to multiply the amount the water rises each day, by the days passed. Then one will have to subtract that from the initial water level, hence the equation formed is the following;
L = 34 - 0.5d
Substitute in 26 for "d", to solve for the water level after 26 days.
L = 34 - 0.5(26)
L = 34 - 13
L = 21

Answer:
(d) f(x) = 2x^2 - 16x + 35
Step-by-step explanation:
The x-coordinate of the extreme will be found at ...
x = -b/(2a)
where the function is f(x) = ax²+bx+c.
The extreme will be a minimum when a > 0. (eliminates choices A and B)
The x-coordinates of the extremes are ...
C: -(-4)/(2(4)) = 1/2
D: -(-16)/(2(2)) = 4 . . . . . matches the requirement
The appropriate choice is ...
f(x) = 2x^2 - 16x + 35
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8

Answer:
After 3 visits both plans will cost the same.
Step-by-step explanation:
Gym A costs $26.76 plus an additional $4 for each visit.
Gym B has no initial fee but costs $12.92 for each visist.
The cost for gym A can be written as
C= $26.76 + 4(x) where x is the number of visits to the gym A
The cost for gym B can be written as
C= $12.92 (x) where x is the number of visits to the gym B
Both costs will be equal
12.92x= 26.76 +4x
12.92x-4x= 26.76
8.92x= 26.76
x= 26.76/8.92
x= 3
after 3 visits both plans will cost the same.
Check
12.92x= 26.76 +4x
12.92*3= 26.76 +12
38.76= 38.76
