Answer: The function has three x-intercepts.
Step-by-step explanation:
To find the x-intercepts of a function, we need to find the values of x for which the function equals zero.
So, to find the x-intercepts of the function:
F(x) = (x+5)^3(x-9)(x-1)
We need to solve the equation:
F(x) = 0
We can see that the function will be equal to zero when any of the factors on the right-hand side is equal to zero. Therefore, we need to solve the following four equations:
(x+5) = 0, which gives x = -5
(x-9) = 0, which gives x = 9
(x-1) = 0, which gives x = 1
(x+5)^3 = 0, which gives x = -5
The last equation, (x+5)^3 = 0, has a triple root at x = -5, since the factor (x+5) appears three times. Therefore, there are a total of three x-intercepts for the function:
x = -5 (with multiplicity 3), x = 1, and x = 9.

An initial deposit of $1200 is put into an account that earns 5% interest, compounded annually. Each year, an additional deposit of $1200 is added to the account.
Through the aid of future value If no withdrawals or new deposits are made, the account's value following the tenth deposit should be $15,093.47.
The implied value of an asset as of a particular date in the future based on a growth rate assumption is known as the Future Value (FV). This area of mathematics examines how random events happen. The value might be between 0 and 1. The mathematical idea of probability aids in predicting the possibility of specific events. In general, probability relates to how probable something is to happen. The interest rate assumption, or the rate of return on the initial amount of capital invested, or the present value, determines the projected future value (PV).
Calculation of the value:
The initial deposit is $1.200
The rate of interest is 5%
Now the future value be like
[tex](1200\times\frac{(1+0.05)^9-1}{0.05} )\times(1+0.05)+1,200\\\\\(1200\times(\frac{1.5513-1}{0.05} )\times(1+0.05)+1,200\\\\(1200\times11.0265)\times(1.05)+1,200\\\\13893.4711+1,200\\$15,093.47[/tex]
Through the aid of future value If no withdrawals or new deposits are made, the account's value following the tenth deposit should be $15,093.47.

What is 576 square root by division method?
Answer:
√576 = 24
Step-by-step explanation:
You want to find the square root of 576 by the long division method.
MethodThe attachment shows the result of applying the method.
The dividend is marked off in 2-digit groups working outward from the decimal point. An overline is typically used. Here, 76 is the group closest to the decimal point, and the next "group" is 5The integer part of the square root of the leftmost 2-digit group is written as the leftmost digit of the root. Here the integer part of the square root of 5 is 2, so that is the first root digit.The quotient digit is appended to the divisor, and the result is multiplied by the root digit. For the first step here, the digit 2 is appended to 0, and multiplied by the root digit 2. The product, 4, is subtracted from the dividend so far, and the next 2-digit group is appended to the result to form the next "dividend."The root so far is doubled and written as the first digits of the new divisor. This will be 2·2 = 4, with space left to append the next root digit: 4_.The next root digit is the largest integer that can be appended to the divisor, and multiplied by that divisor to obtain a value that is at most equal to the "dividend." Here, the second digit of the root is 4, and 44 · 4 = 176. This value is subtracted from the dividend resulting from step 3. Here, they are equal, so the difference is zero, and we're done. If there are more digits and/or the difference is not zero, then the process is repeated from step 3.The root of 576 is 24.

Pablo received $200 dollars for his high school graduation. He wants to save his money to buy a new laptop that cost $700 for when he attends
college. Each month, he adds $125 to his laptop savings. Write an equation in slope intercept form for m, the number of months that it will take Pablo to save $700.
Let's call the number of months that it takes Pablo to save $700 as "m". The amount of money Pablo has saved after "m" months can be represented by the equation:
y = 200 + 125m
where y is the total amount of money saved after "m" months.
To find the number of months it will take Pablo to save $700, we can set y equal to $700 and solve for m:
700 = 200 + 125m
500 = 125m
m = 500 / 125 = 4
So it will take Pablo 4 months to save $700.
The equation in slope-intercept form is:
y = 125m + 200
where m is the number of months and y is the total amount of money saved. The slope of the line is 125, which represents the amount added to the savings each month, and the y-intercept is 200, which represents the initial amount of money Pablo received for graduation.

the standard deviation is a resistant measure of spread. t/f
True, the standard deviation is a resistant measure of spread.
The standard deviation is calculated as the square root of the variance of the data set. Variance is calculated as the average of the squared differences between each data point and the mean of the data set. The standard deviation is the square root of this average.
In mathematical terms, the standard deviation can be calculated using the following formula:
σ = √(1/n ∑(x - μ)²)
Where σ is the standard deviation, n is the number of data points in the data set, x is the value of the i-th data point, and μ is the mean of the data set.
The standard deviation is an important measure because it gives an idea of how much the individual values in a data set differ from the mean.
In summary, the standard deviation is a resistant measure of spread because it gives a robust measure of the spread of the data in a set and is not easily influenced by outliers or extreme values.

The median and the height of an isosceles trapezoid are equal in length. One diagonal of the trapezoid has length $12$. What is the area of the trapezoid?
The area of the isosceles trapezoid is 72 square units.
What is isosceles trapezoid ?A quadrilateral having at least one set of parallel sides and equal length non-parallel sides is called an isosceles trapezium. To put it another way, it is a trapezium whose two non-parallel sides are congruent. The trapezoid's parallel sides are referred to as the bases, and the segments that link the bases are referred to as the legs. The angle between the bases of an isosceles trapezoid determines its height.
Given:
[tex]\[d = 12 \quad \text{(length of one diagonal)}\][/tex]
Let;
[tex]\[h = \text{height of the trapezoid}\][/tex]
[tex]\[a = \text{smaller base of the trapezoid}\][/tex]
[tex]\[b = \text{larger base of the trapezoid}\][/tex]
Using the given information that the height and median are equal, we have:
[tex]Median(m)=\frac{1}{2} {(a+b)}\\\\Height(h)=\frac{1}{2} {(a+b)}\\\\2h=a+b ........(1)[/tex]
[tex]\[\text{Area} = \frac{1}{2} \cdot (a + b) \cdot h\][/tex]
[tex]\[\text{Area} = m \cdot h\] = h^2 ............(2)[/tex] (∵ [tex]Median(m)=\frac{1}{2} {(a+b)}[/tex] and m=h)
Now,
[tex]\[ d = \sqrt{h^2 + \frac{(a+b)^2}{4}} \][/tex] for isosceles trapezoid,
[tex]\[ 12^2 = h^2 + \frac{(a+b)^2}{4}}[/tex]
[tex]\[ 12^2 = h^2 + \frac{(2h)^2}{4}}[/tex] (∵from eq (1))
[tex]\[ 12^2 = h^2 + {(h)^2}}\\ \\144= 2h^2\\\\h^2=72 ..........(2)[/tex]
Lastly, we may change the values of "a," "b," and "h" in the following formula to find the area as;
[tex]\[\text{Area} = \frac{1}{2} \cdot (a + b) \cdot h\][/tex]
[tex]\[\text{Area} = \frac{1}{2} \cdot (2h) \cdot h\][/tex]
