The cost of a phone is reduced by 20%. The new cost is $70.40. What was the original price?
The original price 1. $ 88.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means)
Given;
The cost of the product was reduced by 20%, leaving $ 70.4 as the final price.
Cost of phone after 80% off= $70.40
So, now we will do a cross-multiplication;
If the percent is 80% =70.40
Let, the original price 100% = x
80x = 70.40. 100
80x = 7040
X = 7040: 80
X = 88
Therefore, the 100 percent value of phone will be $88

How do you find the degree and the number of turning points in a polynomial function?
To find the degree of a polynomial function, count the number of terms in the expression. To find the number of turning points, take the degree of the polynomial and subtract 1. The number of turning points will be equal to that number.
To find the degree of a polynomial function, the first step is to count the number of terms in the expression. For example, if the expression is 3x^2 + 4x + 2, then the degree is 2 because there are three terms.The second step is to subtract 1 from the degree of the polynomial. In the example, subtracting 1 from 2 gives us 1. Therefore, the polynomial has 1 turning point.A turning point is a point on the graph of the polynomial where the slope of the tangent line is 0. This means the graph changes direction at the turning point. In the example, the graph changes direction at the point (1, 5).In summary, to find the degree and the number of turning points in a polynomial function, count the number of terms in the expression to find the degree, then subtract 1 from the degree to find the number of turning points.

What is median class example?
The continuous data that is presented as a frequency distribution makes up the median of the grouped data.
The center number in the set of data, known as the median, is what divides the data set's upper and lower halves. Since the data is divided into class intervals, the middle value is unknown when calculating the median of grouped data.
Let us understand this with the help of a median class example.
Consider the data as 48, 20, 59, 69,73. We have to calculate the median.
Arranging in ascending order we get, 20, 48, 59, 69, 73.
Here the number of observations is n = 5.
To find the median of odd data we will use the formula:
[(n+1)/2] = (5+1)/2 = 3.
Therefore, median = 3rd observation.

let h of x equals the integral from negative 5 to x of negative 4 times quantity t minus 2 close quantity squared plus 8 dt. where does h(x) have a relative minimum?
The relative minimum of h(x) occurs at x = 2. Integrals can be used to solve a wide range of problems in mathematics and physics, such as finding the area under a curve
An integral is a mathematical concept that involves the concept of integration, which is a way to find the area under a curve or the volume of a solid of revolution. Integrals can be classified into two types: indefinite integrals and definite integrals.
To find the relative minimum of the function h(x), we need to find the value of x that minimizes the value of h(x).
First, let's find the derivative of h(x). We can do this by applying the chain rule to the function inside the integral:
[tex]h'(x) = (-4 * (t - 2)^2 + 8)' = (-4 * (t - 2)^2 + 8)' = -8 * (t - 2)[/tex]
Next, we need to find the points where h'(x) = 0 or is undefined. Setting h'(x) = 0 and solving for t, we find that t = 2. Substituting this value back into the original expression for h(x), we get:
[tex]h(x) = -4 * (2 - 2)^2 + 8 = 8[/tex]
Since h'(x) is undefined at t = 2, we need to check whether the function is increasing or decreasing at that point. To do this, we can take the second derivative of h(x):
[tex]h''(x) = (-8 * (t - 2))' = -8[/tex]
Since the second derivative is negative at t = 2, this means that the function is decreasing at that point.

How do you find the slope of a perpendicular line with an equation and point?
First, by solving for y, convert the equation of the given line into slope-intercept form y=mx+c .You obtain the slope of the equation as m. Since the slopes of perpendicular lines are negative reciprocal, the slope of the line we're looking is the negative reciprocal of the perpendicular equation.
By entering the supplied point into the formula y = mx + b and solving for b, we arrive at the value of b. Consequently, the line's equation is formed.
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively.
m = y/x = y/x = change in y/change in x
where "m" represents a line's slope.
Additionally, the slope of the line may be shown as

What is the remainder when x³ 3x² 4x 6 x 3?
The expression x³ 3x² 4x 6 can be expanded to x³ + 3x² - 4x - 6. When this expression is evaluated for x = 3, the result is 24, so the remainder is 0.
The expression x³ 3x² 4x 6 can be expanded to x³ + 3x² - 4x - 6. To find the remainder when this expression is evaluated, we must first substitute in a value for x. For this example, let x = 3. When we substitute 3 for x, the expression becomes 3³ + 3x² - 4(3) - 6. We can simplify this expression by performing the operations in order of operations. First, we can calculate 3³, which is equal to 27. Next, we can calculate 3x², which is equal to 27. Subtracting 4(3) from 27 gives us 15. Finally, subtracting 6 from 15 gives us 9.
The remainder of evaluating
x³ 3x² 4x 6 for x = 3 is 9.
x³ 3x² 4x 6 = 3³ + 3x² - 4(3) - 6 = 27 + 27 - 12 - 6 = 24

What are three consecutive odd integers of 57?
The required three consecutive odd numbers that sum up 57 are 17, 19 and 21.
What are consecutive numbers ?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.
Since, we know that any odd number is always of the form (2k +1). We express an odd number in this form because we know that an odd number is not divisible by 2.
Now, the next odd number after (2k+1) will be (2k+3) because if we take (2k+2) then we can see that it is clearly divisible by 2.
So, we can say that the difference between any two consecutive odd numbers is:
= 2k+3 – (2k+1)
=2k+3-2k-1
=2
So, for every two consecutive odd numbers there is a difference of 2.
Now, let us take ‘n’ to be an odd number.
So, an odd number just before n will be (n-2).
And also an odd number just after n will be (n+2).
Since, it is given that the sum of these three consecutive odd numbers is 57. So, we can write the following equation:
n-2+n+n+2=57
3n=57
So, n = 19
The odd number before n will be = n -2 = 19-2 = 17
And the odd number after n will be = n+2 = 19 + 2 = 21
Therefore, The required three consecutive odd numbers that sum up 57 are 17, 19 and 21.

after t years the population of goats on this island, N= 1000
the maximum goat carrying capacity of this island, K= 1500
per capita growth rate, r = 0.5 per year
now, we use logistic growth equation, dN/dt = r×N[(K-N)/K]
dN/dt = 0.5×1000{1500-1000)/1500}
dN/dt= 166.67
∫dN/166.67 = ∫dt
by integrating both sides
N/166.67 = t+c , where c is the

As given by the question , so here the vertical and horizontal asymptotes are at x = -12 and y = 1.5.
What is vertical asymptote?On a function graph, a vertical asymptote represents the point at which the function is undefined. Take the formula f(x) = 1/x as an illustration. This function's graph exhibits a vertical asymptote at x = 0 since the function is undefined at this value (division by 0 is undefined).
What is horizontal asymptote?A function's horizontal asymptote is a horizontal line on the function graph that the function approaches as the input (x-value) increases or decreases dramatically. Consider the function f(x) = x2 as an illustration. Because the y-values of the function do not converge to a fixed value as x grows very big, the graph of this function lacks a horizontal asymptote.
We must identify the values of x at which the function is undefined in order to determine the vertical asymptotes of the function 3x/(2x+24).So, to find the vertical asymptotes of the function, we need to solve the equation 2x + 24 = 0 for x. so x = -12.
