What is unit conversion?
The process of converting the unit form is known as the unit conversion.
For example, in the SI unit system, distance is in meter while in CGS, it is represented in cm.
Given that:
2 inch = 1.5 feet
1 inch = [tex]\frac{1.5}{2}[/tex]
then, 8 inches =[tex]\frac{1.5}{2} *8[/tex]
= 1.5*4
= 6 feet
again, 12 inches= [tex]\frac{1.5}{2} *12[/tex]
= 1.5*6
= 9 feet

11. Find the equation for the circle with center (−2,4) and passing through (5,−3).
Answer:
In standard form: (x+2)² + (y-4)² = 98
Use the distance formula to find radius:
[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
where (x1, y1), (x2, y1) are points
[tex]\rightarrow \sf d = \sqrt{(-2 - 5)^2 + (4-(-3))^2}[/tex]
[tex]\rightarrow \sf d = \sqrt{(-7)^2 + (7)^2}[/tex]
[tex]\rightarrow \sf d = 7\sqrt{2}[/tex]
Equation of circle:
(x-h)² + (y-k)² = r²(x-(-2))² + (y-4)² = (7√2)²(x+2)² + (y-4)² = (7√2)²(x+2)² + (y-4)² = 98The number of 9th graders attending the

greater than the 2012 total. How many 9th
graders are expected to be at the high school
in 2014?
Answer:
432 9th grade a students
Step-by-step explanation:
so In 2012 there the percentage was 11th grade 11% and 12th grade 12% and 9th grade 30% and 10th grade 47%
total is 1200
in 2014 their is 1.2*1200 students as that is adding on 20%
which is 1440
so then do 0.3*1440=432 9th grade a students as that give your 30%

A 90% confidence interval is centered at a _____ and is 90% sure to contain the _______.
a) statistic, variable
b) parameter, statistic
c) statistic, parameter
d) parameter, variable
e) variable, parameter
Answer:
See below
Step-by-step explanation:
A 90% confidence interval is centered at a parameter and is 90% sure to contain the statistic.
When you are running a statistical test, you can create a confidence interval centered at the appropriate parameter (such as the mean) to see if the statistic stated in your null hypothesis is true if it's contained in the interval. Whatever the confidence level is determines how wide the interval will be, and as such, will determine how likely the interval will catch the statistic in question.
Using polynomial long division how can you determine if x-3 is a factor of x^3+4x^2-12x+24
When the remainder of the polynomial is 0, it is a factor and when it is not zero, then it is not a factor.
What is a polynomial?A polynomial is an algebraic equation with at least the power of its being 2.
When the power of the variable is 2, it is called a quadratic equation.
Analysis:
If [tex]x^{3}[/tex] + 4[tex]x^{2}[/tex] -12x + 24 is divided by x -3, quotient is [tex]x^{2}[/tex]
remainder 7[tex]x^{2}[/tex]-12x+24
7[tex]x^{2}[/tex]-12x+24 divided by x-3, quotient is 7x, remainder 10x + 24
10x+24 divided by x-3, quotient is 10, remainder is 54
In conclusion, since it has a non zero remainder, then x - 3 is not a factor of the polynomial.

Solve the equation. - x^2 + 5x + 9 = 0
Answer:
x(1,2) = -5 ± √61) / (-2)
Step-by-step explanation:
The ABC formula of quadratic equation states
x(1,2) = (-b ± √b^2 - 4ac) / 2a
-x^2 + 5x + 9 = 0
a = -1
b = 5
c = 9
Thus x(1,2) = (-b ± √b^2 - 4ac) / 2a
= (-5 ± √(-5)^2 - 4*(-1)*9) / 2*(-1)
= (-5 ± √25+36) / (-2)
= (-5 ± √61) / (-2)

An equation is formed of two equal expressions. The equation that can be used to represent the graph is y=50x+300.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) The rate of change, in this case, signifies the number of followers Zora is gaining per hour. It can be found using any two coordinates of the line.
(x₁ , y₁) = (0,300) = coordinate of point 1,
(x₂ , y₂) = (2,400) = coordinate of point 2,
Now, the rate of change or the slope will be equal to,
[tex]m = \dfrac{y_2-y_1}{x_2-x_1} = \dfrac{400-300}{2-0} = 50[/tex]
Hence, the rate at which Zora will gain followers is 50 followers/hour.
B.) The y-intercept is the value of y when the value of x is 0. Therefore, the y-intercept of the function is 300.
The y-intercept of the graph is 300, which means at the very initial stage Zora will have 300 followers.
C.) The graph is represented by a line, and the general equation of a line is represented by y=mx+c. To know the value of the constant c, substitute the value of the slope and any coordinate in the equation.
[tex]y=mx+c\\300=50(0)+c\\c=300[/tex]
Hence, the equation that can be used to represent the graph is y=50x+300.
