7 , 12 are the answers
Answer:
x = 7
y = 12
Step-by-step explanation:
The key to solving this problem is understanding the properties of exponents:
If you are multiplying two powers with the same base (in this case the base is 6), the result is the base raised to the power of the two exponents added together.
6^1/3+1/4 = 6^x/y
6^7/12 = 6^x/y
So the product would be 6^7/12
Therefore, the answers are:
x = 7
y = 12
Find the measure of A
Answer:
<A = 60°
Step-by-step explanation:
The triangle is 180° Angle A and B add up to 118°
4y° + (3y + 13)° = 118°
7y + 13 = 118°
7y = 105
y = 15
Since you solve for y, plug your y into the angles to solve.
<A = 4y
<A = 4 * 15
<A = 60°
What is the slope of the line that
passes through these two points?
(2, 3)
(2,9)
Answer:
Slope = undefined.
Step-by-step explanation:
Given two points:
(2,3) & (2,9)To Find:
The slopeSolution:
Using slope's formulae,
[m denotes slope]
[tex] \boxed{ \rm{m = \cfrac{y_2 -y_1 }{x_2 - x_1} }}[/tex]
According to the question,here:
(y_2,y_1) = (9,3)(x_2,x_1) = (2,2)Substitute them onto the formulae:
[tex] \rm \: m = \cfrac{9 - 3}{2 - 2} [/tex]
Simplify.
[tex] \rm \: m = \cfrac{6}{2 - 2} [/tex]
[tex]\rm \: m = \cfrac{6}{0} = \boxed{ \rm \: undefined}[/tex]
if an expression contains division by 0 , then It's undefined.
So, slope(m) = undefined.

If using the method of completing the square to solve the quadratic equation
x2 – 14.0 – 40 = 0, which number would have to be added to "complete the
square"?
---
The number that we need to add to "complete the square" when solving x² – 14x – 40 = 0 using the method of completing the square is 49.
To solve a quadratic equation using the method of completing the square, we need to add the square of half of the coefficient of the x term to both sides of the equation.
This will convert the left side of the equation into a perfect square trinomial.
Then, we can take the square root of both sides and isolate the variable x.
To solve the quadratic equation x² – 14x – 40 = 0 using the method of completing the square, we need to add the square of half of the coefficient of x to both sides.
The coefficient of x is -14, so half of it is -7.
The square of -7 is 49.
Therefore, we need to add 49 to both sides of the equation to "complete the square".
Now, we have: x² – 14x + 49 = 40 + 49
Simplifying this gives: (x - 7)² = 89
Taking the square root of both sides gives: [tex]x - 7 = \pm\sqrt{89}[/tex]
Adding 7 to both sides gives:[tex]x = 7 \pm\sqrt{89}[/tex]
Therefore, the number that we need to add to "complete the square" when solving x² – 14x – 40 = 0 using the method of completing the square is 49.

Find the median, first quartile, third quartile, and interquartile range of the data.
14,25,97,55,66,28,92,38,94
Answer:
BELOW IN BOLD.
Step-by-step explanation:
14,25,97,55,66,28,92,38,94
Arrange these in ascending order:
= 14 25 28 38 55 66 92 94 97
The median = middle number = 55.
First quartile = (25+28)/2 = 26.5.
Third quartile = (92 + 94)/2 = 93.
Interquartile range = 93 - 26.5 = 66.5.
An open box is to be made out of a 12-inch by 20-inch piece of cardboard by cutting out squares of equal size from the four corners and bending up the sides. Find the dimensions of the resulting box that has the largest volume.
Answer:
Length = 15.14, width = 7.14 and height = 2.43 inches.
( correct to the nearest hundredth).
Step-by-step explanation:
Let the lengths of the squares cut out be x inches.
Then the width of the box will be 12 - 2x and the length will be
20 - 2x inches.
The height of the box is x inches.
Volume V = x(20-2x)(12-2x)
To find the value of x when V is a maximum we find the derivative and equate it to zero.
V = x( 240 - 64x + 4x^2)
V = 4x^3 - 64x^2 + 240x
dV/dx = 12x^2 - 128x + 240 = 0
4(3x^2 - 32x + 60) = 0
This won't factor so we use the formula:
x = [-(-32) +/- √((-32)^2 - 4*3*60)] / 6
= 8.24, 2.43.
So one of these gives a maximum Volume.
The second derivative
d^2V/dx^2 = 24x - 128
When x = 8.24, this = 69.6 (positive) so this gives a minimum.
x = 2.43 gives a negative value ( -49.7) so this is the maximum
So the dimensions are:-
length = 20 - 2(2.43) = 15.14
width = 12 - 2(2.43) = 7.14
height = 2.43.

Answer:
2(3x+4)
Step-by-step explanation:
Since the 2 is outside of the parenthesis, it means that everything inside of the parenthesis is multiplied by 2
2 x 3x = 6x
2 x 4 = 8
There is a + between 3x and 4, which means that, when simplified, 2(3x +4) = 6x + 8
Option 2(3x + 4 ) is correct.
Step-by-step explanation:
We have equation 6x + 8 .if we take 2 as common, then we will get 3 x and 4 .As we know 2×3= 6 and 2×4 = 8 .=> 2 ( 3x + 4 ) = 6x + 4 .
