solve the equation 9r^2=108r
Answer:
r = 0, r = 12
Step-by-step explanation:
9[tex]r^{2}[/tex]=108r
Subtract 108r from both sides
9[tex]r^{2}[/tex] - 108r = 108r - 108r (simplify) -> 9[tex]r^{2}[/tex] - 108r = 0
Factor 9[tex]r^{2}[/tex] - 108r: 9[tex]r^{2}[/tex] (r - 12)
9[tex]r^{2}[/tex] (r - 12) = 0
r = 0, r = 12

To solve the equation below by completing the square, what is your first step?
3x2 + 18x = 21
Add 9 to each side of the equation.
Divide both sides of the equation by 3
Multiply both sides of the equation by 3
Add 81 to each side of the equation.
Step-by-step explanation:
well, for that I want the equation as simple a possible. especially do I want to have a pure "x²" term with "1" as the factor.
so, as I see that all terms in the equation are multiples of 3, my first step will be to divide both sides by 3.
leading to
x² + 6x = 7
Answer:
Answer:
The first step to solve the equation by completing the square 3x²+ 18x= 21 is multiply both sides of the equation by .
The factors of the equations 3x²+ 18x= 21 are 1 ,-7 .
Step-by-step explanation:
As given the equations
3x² + 18x = 21
Multiply both sides of the equation by .
Thus the equation becomes
Simplify the above
x² + 6x = 7
Adding 9 on both sides of the above equation
x² + 6x + 9 = 7 + 9
x² + 6x + 9 = 16
(As (a +b)² = a² + b² + 2ab
Thus (x+3)² = x² + 6x + 9 )
Put in the above
(x+3)² = 16
Taking square root on both side
√16 = ± 4
First take
(x + 3) = 4
x = 4 -3
x = 1
Second take
(x+ 3) = -4
x = - 4 -3
x = -7
Therefore the first step to solve the equation by completing the square 3x²+ 18x= 21 is multiply both sides of the equation by .
The factors of the equations 3x²+ 18x= 21 are 1 ,-7 .

Lily began a plan for this proof.
Since ∠1 and ∠2 are supplementary and ∠1 and ∠3 are supplementary, then m∠1+m∠2=180° and m∠1+m∠3=180°. If she can get m∠2 and m∠3 to both equal the same expression, she can use the transitive property of equality to set them equal to each other.
How can Lily get m∠2 and m∠3 to both equal the same expression?
Answer:
Step-by-step explanation:
Answer:
she can subtract m < 1 from both sides of m < 1 + m < 2 = 180* and m < 1 + m < 3 = 180*

This is the 4th question
Answer:
a) There are 9 outcomes.
b) **i have attached the tree diagram**
c) 1/9
d) 1/9
Step-by-step explanation:
Both events (choosing a shirt and choosing pants) are not mutually exclusive (disjoint). Meaning that both events can occur at the same time.
a) For a sequence of two events in which the first event can occur m ways and the second event can occur n ways, the events together can occur a total of m • n ways. So for this problem, you would do 3 • 3 which equals 9.
b) **tree diagram is attached**
c) Because there are two different events occurring (choosing a shirt and choosing pants) you need to multiply using the Multiplication Rule for Independent Events : P(A and B) = P(A) * P(B)
The probability of event A occurring (choosing a red shirt) is 1/3 and the probability of event B occurring (choosing brown pants) is also 1/3.
1/3 * 1/3 = 1/9
d) You would do the same thing here as part c.
The probability of event A occurring (choosing a blue shirt) is 1/3 and the probability of event B occurring (choosing blue pants) is again 1/3.
1/3 * 1/3 = 1/9

Find the average value of the function h(x, y) = x3y2 on the region bounded by f(x) = 2x 1, g(x) = −x2 − 2, x = 0, and x = 1
The average value of the function [tex]h(x,y) = x^{3}\cdot y^{2}[/tex] is approximately 3.1496.
How to find the average of a two-variable function
The average is defined by the following double integral equation:
[tex]\bar h = \frac{\int\limits^1_0 {\int\limits^{f(x)}_{g(x)} {x^{3}\cdot y^{2}} \, dy } \, dx }{(1-0)\cdot [y(1)-y(0)]}[/tex] (1)
If we know that [tex]g(x) = -x^{2}-2[/tex] and [tex]f(x) = 2\cdot x - 1[/tex], then the double average is:
[tex]h = \frac{\frac{1}{3} \int\limits^{1}_{0} {x^{3}\cdot [f(x)-g(x)]^{3}} \, dx }{(1-0)\cdot [f(1)-f(0)-g(1)+g(0)]}[/tex]
[tex]h = \frac{\frac{1}{3}\int\limits^{1}_{0} {x^{3}\cdot [2\cdot x-1+x^{2}+2]^{3}} \, dx }{1-1+3-2}[/tex]
[tex]h = \frac{1}{3}\int\limits^{1}_{0} {(2\cdot x^{2}-x+x^{3}+2\cdot x)^{3}} \, dx }[/tex]
The average value of the function [tex]h(x,y) = x^{3}\cdot y^{2}[/tex] is approximately 3.1496. [tex]\blacksquare[/tex]
Remarks
The statement presents mistakes and is poorly formatted:
Find the average value of the function [tex]h(x,y) = x^{3}\cdot y^{2}[/tex] on the region bounded by [tex]f(x) = 2\cdot x - 1[/tex], [tex]g(x) = -x^{2}-2[/tex], [tex]x = 0[/tex] and [tex]x = 1[/tex].

What is the slope of the line that passes through the points (5,8) and (11,5)? Write your answer in simplest form.
Answer:
-1/2.
Step-by-step explanation:
slope of a line is (y2-y1)/(x2-x1). Plug in points (5-8)/(11-5). That gives -3/6. Reduce the fraction by 2, so -1/2 is the answer.

Find the area for number 5.
Answer:
The area of the pentagon is 249 square inches.
Step-by-step explanation:
Given, s = 12in; and a = 8.3, The formula to find the area of a pentagon with apothem is, Area of pentagon = 1/2 × perimeter × apothem. So, let us find the perimeter of the pentagon. Perimeter of the pentagon = 5 × side length.
perimeter = 5 x 12
= 60in.
Area = 1/2 × 60×8.3
= 249in².
What expression represents the width of the rectangle
We are given a rectangle with one of its sides ( length ) equal to ( x - 7 ) Meters.
Also we are given the area of the rectangle as x² - 15x + 56 square meters .We have to find the expression for another side of the rectangle i.e it's width
We will use the formula of area of rectangle to find the expression :
Area = length × widthTherefore,
ㅤㅤ➝ A = l × w
ㅤㅤ➝ x² - 15x + 56 = ( x - 7 ) × w
ㅤㅤ➝ x² - 8x -7x + 56 = ( x - 7 ) × w
ㅤㅤ➝ (x² - 8x )( - 7x + 56 ) = ( x-7 ) w
ㅤㅤ➝ x( x - 8 )-7( x - 8 ) = ( x - 7 )w
ㅤㅤ➝ ( x - 8 )( x - 7 ) = ( x - 7 )
ㅤㅤ➝ ( x - 8 )w = ( x - 8 )( x - 7 )
ㅤㅤ➝ w = ( x - 8 )( x - 7 ) / ( x - 7 )
ㅤㅤ➝ w = ( x - 8 )
