8. Write a rational
expression that is
equal to the following
rational expression
when x doesn’t = 2 or - 3.
5(x-2)/
(x-2)(x+3)

Answer:

1 and - 2

Step-by-step explanation:

f(0) is asking what is the value of y when x = 0

locate x = 0 ( the origin), go vertically up the y- axis to meet the line at (0, 1)

then f(0) = 1

f(x) = 5 is asking what is the value of x when y = 5

locate y = 5 on the y- axis, go horizontally across to meet the line at (- 2, 5 )

then f(x) = 5 when x = - 2

Answer:

No, you cannot fold the figure in half so that one side matches the other.

Step-by-step explanation:

The figure does not have any symmetry, so it cannot be folded in half so that one side matches the other.

The equation of a sphere if one of its diameters has endpoints: (-6, 4, 0) and (0, 0, 6) will be (x+3)2+(y-2)2+(z-3)2=22

d2 = (xf-xi)2 + (yf-yi)2 +(zf-zi)2

d2 = (-6-0)2+(4-0)2+(0-6)2

d2=36+16+36=88

d=sqrt(88)

The radius is half the diameter

r=d/2

r=sqrt(88)/2

Use the center equation to get the diameter's middle.

(xf-xi)/2, (yf-yi)/2, (zf-zi)

(-6-0)/2, (4-0)/2, (0-6)/2

(-3,2,-3) Center

Apply the sphere equation now.

(x-xc)2+(y-yc)2+(z-zc)2=r2

(x+3)2+(y-2)2+(z-3)2=(sqrt(88)/2)2

(x+3)2+(y-2)2+(z-3)2=88/4

(x+3)2+(y-2)2+(z-3)2=22

There are 10,000,000 (10 million) 7-digit combinations. A 7-digit combination is a combination of 7 different numbers (from 0-9). To calculate the total number of combinations, we can use the formula for combinations

A 7-digit combination is a combination of 7 different numbers (from 0-9). To calculate the total number of combinations, we can use the formula for combinations:

n!/(r!(n-r)!)

where n=10 (the number of possibilities for each digit) and r=7 (the number of digits).

10!/(7!(10-7)!) = 10!/7!3! = 10!/(7!3!) = 10 x 9 x 8 x 7 x 6 x 5 x 4/(7 x 6 x 5 x 3 x 2 x 1 x 3 x 2 x 1) = 10 x 9 x 8 x 7 x 6 x 5 x 4/(7 x 6 x 5 x 3 x 2 x 1) = 10 x 9 x 8 x 7 x 6 x 5 x 4/(7 x 6 x 5) = 10 x 9 x 8 x 7 x 6 x 5/7 = 10 x 9 x 8 x 7 x 6 = 10,000,000 (10 million)

If you have 25 members and wish to pick a president, secretary, and treasurer, then we have 13,800 ways to choose the officers, if individual members may hold more than one office.

In the given question,

If you have 25 members and wish to pick a president, secretary, and treasurer, then we have to find how many ways can we choose the officers, if individual members may hold more than one office.

We have a total of 25 members.

They have a total of 3 positions president, secretary, and treasurer.

When the one position of president was filled then there were left 24 members for the secretary position.

When the one position of secretary was filled then there were left 23 members for the treasurer position.

So the possible ways to fill the position are found by multiplying 25,24 and 23. So

Possible ways=25*24*23

Possible ways=13,800

Hence, if you have 25 members, and wish to pick a president, secretary, and treasurer, then we have 13,800 ways to choose the officers, if individual members may hold more than one office.

The solution to the given linear inequality is given in graph.

What is linear inequality?

In mathematics, inequality denotes a mathematical expression in which neither side is equal. In Math, an inequality occurs when a connection produces a non-equal comparison between two expressions or two integers. The equal sign "=" in the phrase is substituted by any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). In mathematics, there are three types of inequalities: polynomial inequalities, rational inequalities, and absolute value inequalities.

The symbols "< and '>' represent strict inequalities, whereas  ‘≤’ and ‘≥’ represent slack inequalities. A linear inequality appears to be a linear equation, however there is a difference in the formula.

Step-by-step explanation:

8.4 of Susan's muffins weigh the same as 7 of Tom's muffins.

We can begin solving the problem by using the proportion:

(18 muffins) / (15 muffins) = (x muffins) / (7 muffins)

where x represents the number of Susan's muffins that weigh the same as 7 of Tom's muffins. To solve for x, we can cross-multiply and then divide:

18 muffins * 7 muffins = 15 muffins * x

x = (18 * 7) / 15

x = 8.4

The percent of adults who are developmentally disabled by the criterion of an IQ score below 70 is approximately 2.28%

We can use the standard normal distribution in order to find the probability of an IQ score below 70.

We know the mean IQ score is 100 and the standard deviation is 15, so we can use the formula:

z = (70 - 100) / 15

z = -2

Using a normal probability table, we find that the probability of a score less than -2 is approximately 0.0228.

Therefore, we get that approximately 2.28% of adults are considered developmentally disabled by the criterion of an IQ score below 70.

The slope intercept equation can be used to determine a straight line's general equation from its slope and the location of its y-axis intersection.

Y = mx + b is the slope intercept form equation.

One formula for figuring out a line's equation is the slope-intercept formula. A line with slope m and a y-intercept of b has a slope-intercept formula of y = mx + b. Any point on the line can be found at (x, y).

From graph we can see that the graph passing through the points (3, 0) and (0, 6).

We have to find the slope intercept form of line.

First to find the slope of the line.

m = [tex]\frac{y_2-y_1}{x_2-x_1} = \frac{6-0}{0-3}=\frac{6}{-3} = -2[/tex]

Slope of the line is -2.

Answer: The perimeter of a shape is the sum of all its sides.

From the diagram, we can see that the shaded shape is composed of a square and a rhombus.

The square has 4 sides of equal length, which is the same as the length of one of the diagonals of the rhombus.

The rhombus has 4 sides with two sides of equal length (the diagonals) and two sides of equal length (the parallel sides).

We can call the length of the diagonals of the rhombus as "d" and the length of the parallel sides of the rhombus as "s".

So, the perimeter of the shaded shape is:

Perimeter = 4s + 4d

It is not possible to find the perimeter with out knowing the length of the sides of the rhombus and the square.

The value of x in simplest radical form is 8√3.    

A radical in mathematics is the opposite of an exponent, which is symbolized by the sign "√" also known as root.

The number before the symbol or radical is regarded as an index number or degree, and it can either be a square root or a cube root.  

The radical and root of a number are the same thing.      

Here we have

Given triangle is a right-angled triangle

From trigonometric ratios,

Sin θ = [ Opposite side ]/[ Hypotenuse ]

=> Sin 30° = [ Opposite side ]/[ 16 ]  

As we know, Sin 30° = 1/2

=> [ Opposite side ]/[ 16 ] = 1/2

=> Opposite side = 8 units      

By the Pythagorean theory,

Hypotenuse² = Opposite side² + Adjacent side²  

=> 16² = 8² + x²  

=> 256 = 64 + x²

=> x² = 192  

=> x = √64 × 3  

=> x = 8√3
