Answers
A perfect square is a number that is gotten by multiplying it by itself.
An example of a perfect square is 25 and one that is not is 7.
What is a perfect square?A square number, sometimes known as a perfect square, is an integer that is the square of another integer; in other words, it is the product of another integer and itself. For instance, 9 is a square number since it equals 3² and may be expressed as 3 × 3.
A perfect square is a number that can be written as the product of two integers or as an integer's second exponent. 25 is a perfect square because it is the product of the integer 5 and itself, 5 × 5 = 25. A perfect square is a positive integer formed by multiplying an integer by itself.

Answers
Given that
There is a cylinder and we have to find the change in its volume if the radius is doubled and the height is halved.
Explanation -
Let the Initial radius be r and the height be h. Then the initial volume will be
[tex]v=\pi\times r^2\times h-----------(i)[/tex]Now applying the given changes,
new radius = 2 x r
new height = h/2
Then the new volume will be V,
[tex]\begin{gathered} V=\pi\times(2r)^2\times\frac{h}{2} \\ \\ V=\pi\times4r^2\times\frac{h}{2} \\ \\ V=2\times\pi\times r^2\times h \\ \\ On\text{ substituting v = }\pi\times r^2\times h \\ \\ V=2\times v \end{gathered}[/tex]Hence volume will be doubled. And option D is correct.

Here are 5 lines on a coordinate grid: Write equations for lines a,b,c,d and e a: b: c: d: e:
Answers
The equations of each of the given lines are:
Line a is: x = -4
Line b is: x = 4
Line c is: y = 4
Line d is: y = -2
Line e is: y = -¾x + 1
How to Write the Equation of a Line?If we determine the slope value, m, and the y-intercept value, b, the equation of a line can be written as y = mx + b in slope-intercept form by plugging in the values of the determined variables.
For a vertical line, the equation is expressed as x = b, where b is the x-intercept of the line.
For a horizontal line, the equation would be y = b, where b is the line's y-intercept value.
Equation of line a (vertical line):
The x-intercept is -4. This means that, the equation of line a is: x = -4
Equation of line b (vertical line):
The line's x-intercept is 4. To write the equation of the line, substitute the value of the x-intercept into x = b.
Therefore, the equation of line b is: x = 4
Equation of line c (horizontal line):
The y-intercept (b) = 4. Substitute the b = 4 into y = b.
The equation of line c is: y = 4
Equation of line d (horizontal line):
y-intercept (b) = -2. Substitute b = -2 into y = b.
Equation of line d is: y = -2
Equation of line e:
Slope (m) = rise/run = -3/4
y-intercept (b) = 1
To write the equation of the line, substitute m = -¾, and b = 1 in the equation y = mx + b
y = -¾x + 1

According to the factor theorem, if "a" is any real integer and "f(x)" is a polynomial of degree n larger than or equal to 1, then (x - a) is a factor of f(x) if f(a) = 0.Finding the polynomials' n roots and factoring them are two of their principal applications.
Calculate p(x(*r(x)?
The factorization of 62 + 17x + 5 by dividing the middle word can be used as an illustration of the factor theorem.In this example, two numbers, "p" and "q," can be discovered in such a way that p + q = 17 and pq = 6 x 5 = 30.One can then obtain the factors after that. A factor of | A | is (x - a) if each member of matrix A is a polynomial in x and | A | vanishes for x = a.When p(x) is divided by xc, the result is p if p(x) is a polynomial of degree 1 or higher and c is a real number (c).For some polynomial q, p(x)=(xc)q(x) if xc is a factor of polynomial p.Consequently, p(c)=(cc)q(c)=0, indicating that c is a polynomial zero.
I This theorem comes in very handy when we need to determine the determinant's value in "factors" form.
p(x) =5x
r(x) = 3x - 7
p(x)×r(x) =

a political candidate has asked you to conduct a poll to determine what percentage of people support her. a) suppose the candidate believes that the percentage that support her is approximately 73%. if we want a 6% margin of error at a 94% confidence level, what size sample is needed?
Answers
The sample size needed will be equal to n = 149.
The (1 - α)% confidence interval for population proportion is given by
CI = p ± z(α/2)√p (1 - p)/n
The margin of error will be given as
MOE = z(α/2)√p (1 - p)/n
We know that approximately 73% people support the candidate and margin of error is 0.06.
The critical value of z for confidence level 94% is given by z = 1.65. Now, using the formula of Margin of Error.
MOE = z(α/2)√p (1 - p)/n
n = [z(α/2)√p (1 - p)/MOE]²
n = [1.65√0.73 (1 - 0.73)/0.06]²
n = 148.84
n = 149 approximately which is the required sample size.

Answers
The equation that relates the number of chirps per minute x, and the outside temperature in degrees Fahrenheit is x = 4f -148. If the snowy tree cricket chirps 100 times in a minutes, the the outside temperature is 62 degrees Fahrenheit.
The number of chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.
The number of chirps per minute = x
The outside temperature in degrees Fahrenheit = f
Then the linear equation will be
x = 4f - 148
Given that x = 100 chirps per minutes
Substitute the values in the equation
100 = 4f -148
4f = 100+148
4f = 248
f = 248/4
f = 62 degrees Fahrenheit.
Hence, the equation that relates the number of chirps per minute x, and the outside temperature in degrees Fahrenheit is x = 4f -148. If the snowy tree cricket chirps 100 times in a minutes, the the outside temperature is 62 degrees Fahrenheit.
