The interest rate on Malik's saving account is 4.62%. This was calculated by finding the total amount after 4 years, subtracting the original deposit, and then dividing the interest earned by the original deposit and multiplying by 100.
1. Calculate the total amount in the account after 4 years: 1050 + 241.50 = 1291.50
2. Calculate the interest earned: 1291.50 - 1050 = 241.50
3. Calculate the interest rate: 241.50 / 1050 x 100 = 4.62%
The interest rate on Malik's saving account is 4.62%. This was calculated by finding the total amount after 4 years, subtracting the original deposit, and then dividing the interest earned by the original deposit and multiplying by 100.

A line passes through the points (-1,-9) and (1,7) write it’s equation in slope intercept form 
The equation of the line in slope intercept form is y = 8x -1.
What is slope intercept form?
The graph of the equation y = mx + b is a line with slope m and y-intercepts b. The form of the linear equation is called the slope-intercept form, and the values of m and b are real integers.
The slope, m, of a line indicates how steep it is. The gradient of a line is another name for the slope of a line. The y-intercept of a line is the y-coordinate of the location where the line's graph crosses the y-axis.
We are given two points which are (-1,-9) and (1,7).
First, we need to find the slope(m)
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m=\frac{7 +9 }{1+1 }[/tex]
m = 16/2
m = 8
We know that b = y₁ - x₁(y₂ - y₁)/(x₂ - x₁)
So,
⇒b = (-9) + 1(7 + 9)/(1+1)
⇒b = -9 + 8
⇒b = -1
The equation comes out to be
⇒y = mx + b
⇒y = 8x -1
Hence, the equation of the line in slope intercept form is y = 8x -1.

to raise money, a physics club sells tickets to a physics demo extravaganza. the tickets cost $6 for adults over 18 and $4 for younglings. after the show, they have raked in a total of $438 from the 82 people who came. how many adults and how many younglings attended?
There are 55 adults and 27 younglings attended the club.
let the number of adults attended the club be x
let the number of younglings attended the club be y
total people attended the club = 82
so,
x + y = 82.....[1]
cost for the adult = $6
cost for the younglings = $4
so total amount collected = $438
so, equation formed is ,
6x + 4y = 438.......[2]
from equation [1]
x + y = 82
x = 82 - y
put this in equation [2]
6(82 - y) + 4y = 438
492 - 6y + 4y = 438
492 - 2y = 438
492 - 438 = 2y
2y = 54
y = 27
put this value in equation [1]

The equation p(n) = 12/5n²-17 represents the overall profit
from production for a company where p is the total profit
in dollars and n is the number of hours per day that
the production line operates. Determine the profit when
n = 101/2 hours.
The profit when n = 101/2 hours is $1,842.50.
Determine the profit when n = 101/2 hours.When the production line operates for 101/2 hours, the total profit can be determined using the equation p(n) = 12/5n²-17.When n = 101/2, the equation becomes p(101/2) = 12/5(101/2)²-17.By simplifying this equation, we can find that the total profit for 101/2 hours of production time is p(101/2) = $723.Therefore, when the production line operates for 101/2 hours, the total profit for the company will be $723.The equation p(101/2) = 12/5(101/2)^2 - 17 can be used to determine the total profit when the production line operates for 101/2 hours. To solve this equation, the expression 12/5(101/2)^2 can be simplified to 12(101)^2/25 which evaluates to 12,405. Subtracting 17 from this result yields a total profit of 12,388 dollars when the production line operates for 101/2 hours. The profit when n = 101/2 hours can be calculated by substituting the value of n into the equation p(n) = 12/5n²-17. This yields a total profit of $323.36 when the production line operates for 101/2 hours.To learn more about the overall profit from production refer to:

What is probability and its types? Probability is the measure of the likelihood that an event or a set of events will occur. It is a mathematical concept used to quantify the chance of a certain outcome. It is usually expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty.There are two types of probability: classical probability and empirical probability. Classical probability uses a series of assumptions to calculate the probability of an event. It is based on the assumption that all outcomes are equally likely. Empirical probability is based on observed data and is used when the data is too complex to calculate using classical probability.Probability can be used to make predictions and decisions. For example, if a person is deciding whether or not to purchase a lottery ticket, they can use probability to calculate the chances of winning. Probability is also used in data analysis and forecasting to help make better decisions.Probability is an important concept in statistics and is used in a variety of fields including medicine, engineering, economics, and finance.

What is a graph of a quadratic function?
A graph of a quadratic function is a type of parabola, which is a symmetric, U-shaped curve that opens either upward or downward. The equation of a quadratic function is y = ax² + bx + c, where x and y are variables, and a, b, and c are constants.
The graph of a quadratic function is determined by the value of the coefficient a. If a is positive, the parabola opens upward, and if a is negative, the parabola opens downward. The vertex of the parabola is the highest or lowest point on the graph and it is the point of symmetry of the parabola. The x-coordinate of the vertex is given by -b/(2a) and the y-coordinate of the vertex is given by the value of the function at that point.
In the given figure, we can see that it is a parabola, and if we look towards the options, then the third option is a domain of the given function

The simplest function in a family of functions that yet preserves the definition (or shape) of the entire family is known as a parent function in mathematics.
When the independent variable (often 'x') varies by a constant amount and the dependent variable (typically expressed by 'y') changes by a constant amount, the function is said to be linear.

I just need to know the value of s
Answer:
S = 25
Step-by-step explanation:
Since it's stated as a square, that means all sides equal each other
In other words;
s+50 = 3s
To get S alone, we will first subtract 50 on both sides
s = 3s-50
Let's now subtract 3s from both sides
s-3s = -50, aka -2s = -50
Changing those to positive, 2s = 50
Last step is to divide both sides by 2
s = 25

The Radius r changing with respect to time when volume v is [tex]\frac{1}{9 \pi} \mathrm{cm} / \mathrm{s}\end{aligned}[/tex].
The volume here depends on the diameter of the radius of the sphere since if we take the cross-section of the sphere, it is a circle. The surface area of sphere is the area or region of its outer surface. To calculate the sphere volume, whose radius is ‘r’ we have the below formula:
Volume of sphere [tex]=\frac{4}{3} \pi r^{3}[/tex]
If you consider a circle and a sphere, both are round. The difference between the two shapes is that a circle is a two-dimensional shape and a sphere is a three-dimensional shape which is the reason that we can measure the Volume and area of a Sphere.
volume is,
[tex]$$\begin{aligned}& V=\frac{4}{3} \pi r^3 \\& \Rightarrow \frac{d V}{d t}=4 \pi r^2 \frac{d r}{d t}\end{aligned}$$[/tex]

What is the equation of line with a slope of 1 and passing through (0,4)?The slope-intercept form is expresses as;
y = mx + b
Where m is slope and b is y-intercept.
