Recursion uses more memory compared to iteration because every time the recursive function is called the function call is stored in stack, The correct option is B
What is Recursion?Recursion is the process of defining a problem or the solution to a problem in terms of a simpler version of itself. There two types of recursion the first one is called direct recursion when the second is called indirect recursion.
Therefore recursion is a method of solving problem where the solution depends on solutions to smaller instances of the same problem.

Jack and Anjali each improved their yards by planting hostas and geraniums. They bought their supplies from the same nursery. Jack spent $138 on 6 hostas and 6 geraniums. Anjali spent $116 on 6 hostas and 4 geraniums. Find the cost of one geranium
Answer:
11$
Step-by-step explanation:
We will use simultaneous equation
X = hostas
Y = geraniums
6X + 6Y = 138 ----> (first equation)
6X + 4Y = 116 -----> (second equation)
(Substract)
6X + 6Y = 138
6X + 4Y = 116
2Y = 22
Y = 22/2
Y = 11$

a dog of this breed weighs 52 pounds. what is the dog's z-score? round your answer to the nearest hundredth as needed. z
The z score of a dog of this breed weighs 52 pounds is 0.571. The weight of the dog if z is -0.35 is 45.55 kg. The weight of the dog if z is 0.35 is 50.45 kg.
A z score refers to a numerical measurement that defines a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.
The z score is given by:
z = (x - µ)/σ
where x is the raw score, µ is the mean, and σ is the standard deviation.
In the given case,
x = 52 pounds
µ = 48 pounds
σ = 7 pounds
Hence,
z = (52 - 48)/7 = 0.571
If z = -0.35
Then
-0.35 = (x - 48)/7
x - 48 = -2.45
x = 45.55 kg
Hence, the weight of the dog if z is -0.35 is 45.55 kg.
If z = 0.35
Then
0.35 = (x - 48)/7
x - 48 = 2.45
x = 50.45 kg
Hence, the weight of the dog if z is 0.35 is 50.45 kg.
Note: The question is incomplete. The complete question probably is: The weights of a certain dog breed are approximately normally distributed with a mean of 48 pounds, and a standard deviation of 7 pounds. A dog of this breed weighs 52 pounds. What is the dog's z-score? Round your answer to the nearest hundredth as needed. A dog has a z-score of -0.35. What is the dog's weight?

In 2015, a salesman was paid a basic monthly salary of rs 28 000. At the end of the year, he was also paid a bonus of 7 % of the value of the sales that he had made during the year. His total income for that year was Rs 441 000. Calculate the value of the sales that he made that year
Answer:
1,500,000
Step-by-step explanation:
Let's assume the value of sales that the salesman made during the year to be x.
The bonus that he received at the end of the year is 7% of the value of the sales he made. So, his bonus would be 0.07x.
Therefore, his total income for the year is his basic monthly salary plus the bonus he received. We know that his total income was Rs 441,000. Hence, we can write:
28,000 * 12 + 0.07x = 441,000
Simplifying this equation:
336,000 + 0.07x = 441,000
0.07x = 105,000
x = 1,500,000
Therefore, the value of the sales that the salesman made during the year was Rs 1,500,000.
let x as the total sales
441 000 = 12(28 000) + 0.07x
441 000 = 336 000 + 0.07x
441 000 - 336 000 = 336 000 - 336 000 + 0.07x
105 000 = .07x
x = 1 500 000
CHECKING:
12 * 28 000 = 336 000 (12 months salary)
0.07(1 500 000) = 105 000 (total sales)
336 000 + 105 000 = 441 000
Therefore, salesman total sales for the whole year is RS 1 500 000.

find the equation of a parabola whose vertex (0,0) axis yaxis ; passes through A(-1,1)
The equation of a parabola with vertex at (0, 0) and axis of symmetry along the y-axis is of the form y = ax^2. The parabola passes through the point (-1, 1), so we can set up the following equation:
y = a * x^2
1 = a * (-1)^2
Solving for a, we get a = 1. Therefore, the equation of the parabola is y = x^2.

Tree integers are such that their GCD and LCM are 6 and 1080 respectively.If the first two numbers are 60 and 72, find the number
Answer:
The three integers are 30, 180, and 540.
Step-by-step explanation:
The greatest common divisor (GCD) of two numbers is the largest number that divides both numbers without a remainder. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers.
In this case, we are given that the GCD and LCM of three integers are 6 and 1080, respectively. This means that the three integers must have a GCD of 6 and an LCM of 1080.
We are also given that the first two numbers are 60 and 72. The GCD of 60 and 72 is 12, which is not equal to 6. Therefore, these two numbers cannot be the first two integers.
To find the three integers, we need to find two numbers with a GCD of 6 and an LCM of 1080. One possible pair of numbers is 30 and 180, which have a GCD of 6 and an LCM of 180.
The third number must be a multiple of 6 and a factor of 1080. A possible value for the third number is 540, which is a multiple of 6 and a factor of 1080.
The three integers are 30, 180, and 540.
solve the given initial-value problem. the de is homogeneous. xy2 dy dx = y3 − x3, y(1) = 2
Answer: The differential equations is
y3 3x3logx = 8x3.
Step-by-step explanation:
break the given original- value problem. The DE is homogeneous. xy2dy/ dx = y3- x3; y( 1) = 2.
result
Given a homogenous discriminational equation, xy2 dy/ dx = y3- x3
xy2dy/ dx = y3- x3
dy/ dx = ( y3- x3)/ xy2
dy/ dx = (( y/ x) 3- 1)/( y2/ x2)---( 1)
Put y/ x = v ⇒ y = xv
separatew.r.t x
dy/ dx = x.dv/ dx v
Equation( 1) becomes,
⇒ dv/ dx v = ( v3- 1)/ v2
⇒ dv/ dx = (( v3- 1)/ v2)- v
⇒ dv/ dx = ( v3- 1- v3)/ v2
v2. dv = -1/x.dx
Integrate on both sides, we get
∫ v2. dv = ∫- 1/x.dx
v3/ 3 = - logx C
1/3( y3/ x3)) log x = C( 2)
Now, given that y( 1) = 2
Substituting y = 2 and x = 1 in equation( 2)
(1/3) ×(23/13)) log 1 = C
C = 8/3
From equation( 2), we get

Solve for x of one of the equations so that the repeating (common) variable can be cancelled out.
Using 2x+4=12, we can solve for the x-value and replace it back into y.
2x+4=12

Let dd be the real distance among the kite and the female, vv be the vertical distance among the female and the kite, and hh horizontal distance. Since the vertical distance is a constant (v = 300v=300) we understand that:

a⁴ + b⁴ = 2⁴ + 5⁴
Evaluate the exponents
'This gives
a⁴ + b⁴ = 16 +625
Evaluate the sum
'This gives
a⁴ + b⁴ = 641
Hence, the solution is 641

Given that a = 2 and b = 5
WHAT IS a^4 + b^4
Parallel and perpendicular through points
The equation of the line that passes through the point (6,-4) and is perpendicular to the line 2x - y = 5 is 5y + x = -14.
What is a line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Given:
Point (6,-4),
2x - y = 5,
Calculate the slope as the line is perpendicular to line 2x - y = 5
m = 2
The slope of the line perpendicular, m = - 1 / 5
Calculate the equation of the line as shown below,
[tex]y - (-4) = - 1 / 5 (x - 6)[/tex]
5 (y + 4) = -x + 6
5y + 20 = -x + 6
5y + x = -14
Therefore, the equation of the line that passes through the point (6,-4) and is perpendicular to the line 2x - y = 5 is 5y + x = -14.
