What is the geometric mean of 4 and 1 ninth?
Their geometric mean is:sqrt(42*(1/9)2)=sqrt(16*(1/81))=sqrt(16/81)=4/9-------------------The geometric mean of a set of n terms is equal to the nth root of the product of those n terms. The geometric mean of 4 and 1/9 is sqrt(4*(1/9)) = sqrt(4/9) = 2/3.
What is the distance between the points -1 -9 and 4 -2?
Points: (-1, -9) and (4, -2) Distance: (-1-4)2+(-9--2)2 = 74 and the square root of this is the distance which is about 8.602 to 3 decimal places
How many sides do 1 dodecagon 2 nonagons 1 quadrilateral and 4 triangles have altogether?
A dodecagon has 12 sides, a nonagon has 9, and quadrilateral has 4, and a triangle has 3. So in 1 dodecagon, 2 nonagons, 1 quadrilateral, and 4 triangles there are 1*12 + 2*9 + 1*4 + 4*3 = 12 + 18 + 4 + 12 = 46 sides altogether.
How many sides do 4 hexagons 1 nonagon and 8 pentagons have altogether?
The real answer is 29 . First, find the number of sides for each group of shapes. 1 nonagon: 1 × 9 = 9 4 pentagons: 4 × 5 = 20 Now add to find the total number of sides: 9 + 20 = 29 They have 29 sides in all.
If a triangle has the height of 4 in and an area of 18 in what is the length of the base?
Answer: 9 in Area is 1/2 base x height So 18 = 1/2 b x 4 That means the base is 36/4 or 9
Is (9-1) a solution of x plus 5y4?
If you mean x+5y = 4 then (9, -1) is the solution
Is 9 comma -1 a solution of x plus 5y equals 4?
yes
Is 9 -1 a solution of x plus 5y equals 4?
yes it is..your welcome
Is 9-1 a solution of x 5y 4?
Without the appropriate mathematical signs the given terms have no solutions.
Simplify the expression 5y-4 plus 9y-1 y plus 15?
5y - 4 + 9y - 1y + 15= 5y + 9y - 1y + 15 - 4= (5 + 9 - 1)y + (15 - 4)= 13y + 9
5y plus 4 - 2y equals 9?
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
5y-1 equals y plus 9?
Simplifying 5y + -1 = y + 9 Reorder the terms: -1 + 5y = y + 9 Reorder the terms: -1 + 5y = 9 + y Solving -1 + 5y = 9 + y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1y' to each side of the equation. -1 + 5y + -1y = 9 + y + -1y Combine like terms: 5y + -1y = 4y -1 + 4y = 9 + y + -1y Combine like terms: y + -1y = 0 -1 + 4y = 9 + 0 -1 + 4y = 9 Add '1' to each side of the equation. -1 + 1 + 4y = 9 + 1 Combine like terms: -1 + 1 = 0 0 + 4y = 9 + 1 4y = 9 + 1 Combine like terms: 9 + 1 = 10 4y = 10 Divide each side by '4'. y = 2.5 Simplifying y = 2.5
What ordered pair is the solution of 2x 5y -9 3x 4y -2?
-2,4
What is the equation inverse of fx equals 5x-1 divided by 9?
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
4x plus 5y equals 2 7x minus 2y equals 1 solve by substitution?
4x + 5y = 2 and 7x - 2y = 1 From the first equation, x = (2 - 5y)/4 putting this value of x to the second equation, 7(2 - 5y)/4 - 2y =1 => (14 - 35y)/4 - 2y = 1 =>14 - 35y - 8y = 4 =>14 - 43y = 4 =>43y = 10 => y = 10/43 putting y = 10/43 in x = (2 - 5y)/4 => x =( 86 - 50 )/172 => x = 36/172 => x = 9/43 therefore, x = 9/43 and y = 10/43
What is the value of y if 3y is a solution to the equation 5y-3y equals 18?
5y - 3y = 18 2y = 18 y = 18/2 y = 9
What is 15y2 plus 45y - 9 equals 4y - 5y2?
15y2 + 45y - 9 = 4y - 5y2; thus, 20y2 + 41y - 9 = (5y - 1)(4y + 9) = 0. Therefore, the solution to the equation given is, y = 1/5 or -2¼.
