How many inverse variation functions have (2,3) as a solution?

Using the mathematical operation such as division, the swim team, which has 100 people on it, needs 7 minivans to take them on the other side of town.

If there are 100 people on the swim team that will be divided into minivans that can only occupied by 15 people, divide 100 by 15 to know how many vans they will need.

100 people ÷ 15 people/minivan

100 ÷ 15 = 6 r 10

This means that the swim team will need 6 minivans and still, 10 people don't belong to any minivan yet. So, 1 additional minivan will be needed for the remainder of 10 people.

Hence, the swim team will be needing 7 minivans to cater 100 people on their team.

Rationalization is multiplying a surd by another similar surd to obtain a rational number. In mathematics, a surd is an expression involving a square, cube, or another kind of root symbol. The surd used for multiplication is called the rationalization factor (RF). Rationalize the denominator to make it easier to perform calculations with rational numbers. Rationalizing a denominator with a fraction removes all root terms, such as square roots and cube roots, from the denominator.

The equation of the line in point-slope form is y-1 = 3 ( x + 1)

Equation of a line:

The equation of a line, in point-slope form, is designated  using:

y-y0= m( x - x0)

In which the point is given by(x0,y0)  and m is the slope.

Answer:

the area is 935 square inches, and the perimeter is 39 inches

Step-by-step explanation:

Hey there!

In order to find the perimeter and area of the board, we must first list out the information we already know

----------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------

There is a tiny pattern in here:

The original board has a length of 44 while the new one has the length of 11

This means that, the original board had dimensions 4 times the length of the new board

In order to find the area or perimeter, we need to know the width of the new board

To do this, we divide 1496 by 44

That gets us 34

This means that the width of the old board is 34

Now we divide 34 by 4 which gets us 8.5

This means, 8.5 is the width of the new board

Now that we know this, we can easily find the area and the perimeter of the new board

8.5 + 8.5 + 11 + 11 = 39

This means, the perimeter is 39

8.5 x 11 = 935

This means, the area is 935

This brings us to the conclusion that the area is 935 square inches, and the perimeter is 39 inches!

Part A:  Expression for the distance in meters between given two birds using subtraction = 2.5 - (-2.5)

Part B: The distance between two birds using additive inverse 2.5- (-2.5) =5 meters

An expression is an combination of numbers and mathematical operations such as addition, subtraction, division and multiplication with equating any two terms.

Additive inverse : Additive inverse of an number a is the number that  when adds to a gives zero .

Let b be additive inverse of a, then a + b =0

Then, b = -a

Given two birds A and B are at  points x= -2.5 and  y = 2.5 respectively

Therefore,  the expression for the distance in between given two birds

           = y - x  = 2.5- (-2.5)

We an clearly see that  -2.5 is additive inverse of 2.5

Distance between the two birds = 2.5 -(-2.5) =2.5 +2.5 = 5 meters

Therefore, the expression for distance between the two birds A and B is 2.5-(-2.5) and the distance is 5 meters.

Actual miles is [tex]191\frac{9}{13}[/tex]  ≈ 1.916923 ×[tex]10^{2}[/tex]

Definition of miles per hour unit: ≡ 1 mi / 3600 s = 1609.344 m / 3600 s. In American public life, this is the most commonly used speed unit. Cars speeds are measured in mpg. Interpretation: The speed at which the body moves 1 mile (or 1609.344 metres) in 1 hour.

Definition of feet per second unit: ≡ 1 ft / 1 s = 30.48 cm / 1 s. Abbreviation is fps. In America, perhaps this is the second most commonly used speed unit in public life (after miles per hour). Definition: The speed at which the body moves 1 foot (or 30.48 centimetres) in 1 second.

Convert Miles to Feet

Multiply your speed in miles per hour by 5,280. This is the number of feet in a mile. The result is your speed in feet per hour. For example, 60 miles per hour times 5,280 feet per mile is 316,800 feet per hour.

Convert to Feet per Minute

Divide your speed in feet per hour by 60. This is the number of minutes in an hour. Therefore, the result is your speed in feet per minute. For example, 316,800 feet per hour divided by 60 minutes per hour is 5,280 feet per minute.

Convert to Feet per Second

Divide your speed in feet per minute by 60. This is the number of seconds in a minute. Therefore, the result is your speed in feet per second. For example, 5,280 feet per minute divided by 60 seconds in a minute equals 88 feet per second.

x = -1, y = -4

Step-by-step explanation:

Both equations are equal to y, so just set x - 3 = x^2 - 5 and solve.

Answer:

x = 0.25

Step-by-step explanation:

[tex]9\sqrt{x} =5-2x[/tex]

[tex]81x = 25 - 20x + 4x^{2}[/tex]

[tex]0=4x^{2} -101x+25[/tex]

[tex]0 = 4x^{2} -1x-100x+25[/tex]

[tex]0=x(4x-1)-25(4x-1)\\0=(x-25)(4x-1)[/tex]

[tex]x=25,\frac{1}{4}[/tex]

[tex]2*25+9\sqrt{25} =5\\50+9*5=5\\50+45=5\\95=5[/tex]

[tex]2*\frac{1}{4}+9\sqrt{\frac{1}{4} } =5 \\0.5+9*\frac{1}{2} =5\\0.5+4.5=5\\5=5[/tex]

Answer:

[tex]x=\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given equation:

[tex]2x+9\sqrt{x}=5[/tex]

Subtract 2x from both sides to isolate the square root:

[tex]\implies 2x+9\sqrt{x}-2x=5-2x[/tex]

[tex]\implies 9\sqrt{x}=5-2x[/tex]

Square both sides to eliminate the square root:

[tex]\implies (9\sqrt{x})^2=(5-2x)^2[/tex]

[tex]\implies 81x=(5-2x)(5-2x)[/tex]

[tex]\implies 81x=25-20x+4x^2[/tex]

Subtract 81x from both sides:

[tex]\implies 81x-81x=25-20x+4x^2-81x[/tex]

[tex]\implies 0=25-101x+4x^2[/tex]

[tex]\implies4x^2-101x+25=0[/tex]

To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]:

[tex]\implies ac=4 \cdot 25=100[/tex]

[tex]\implies b=-101[/tex]

Therefore, the two numbers are -1 and -100 as:

[tex]\implies -1 \cdot -100=100=a[/tex]

[tex]\implies -1+(-100)=-101 =b[/tex]

Rewrite [tex]b[/tex] as the sum of these two numbers:

[tex]\implies4x^2-x-100x+25=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies x(4x-1)-25(4x-1)=0[/tex]

Factor out the common term (4x - 1):

[tex]\implies (x-25)(4x-1)=0[/tex]

Apply the zero-product property:

[tex](x-25)=0 \implies x=25[/tex]

[tex](4x-1)=0 \implies x=\dfrac{1}{4}[/tex]

Input each solution into the original equation to check its validity:

[tex]\begin{aligned}x=25 \implies 2(25)+9\sqrt{25}&=5\\50+9(5)&=5\\50+45&=5\\95 & \neq 5\end{aligned}[/tex]

Therefore, x = 25 is not a valid solution.

[tex]\begin{aligned}x=\dfrac{1}{4}\implies 2\left(\dfrac{1}{4}\right)+9\sqrt{\dfrac{1}{4}}&=5\\\dfrac{1}{2}+9(\dfrac{1}{2})&=5\\\dfrac{1}{2}+\dfrac{9}{2}&=5\\\dfrac{10}{2}&=5\\5 & = 5\end{aligned}[/tex]

Therefore x = ¹/₄ is a valid solution.

Therefore, the only valid solution to the equation is x = ¹/₄.

Median - The middle number in the data set when ordered from least to greatest.

Mode - The value that appears most frequently.

Mean:

We can add them up and divide by the number of values in the set, 7.

469 / 7 = 67

Median:

We can order them from least to greatest and see which one is the 4th one.

60, 62, 66, 67, 68, 68, 78.

67 is in the middle, so that is our median.

The equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2

The equation of the line is given as

y = 4x - 3

Rewrite the equation as

y = 4x - 3

A linear equation is represented as

y = mx + c

Where

Slope = m

So, we have

m = 4

The slopes of perpendicular lines are opposite reciprocals

This means that

m2 = -1/m1

So, we have

m = -1/4

Evaluate

m = -1/4

The equation of the perpendicular line is then calculated as

y = m(x - x1) + y1

Where

(x1, y1) = (2, -2)

This gives

y = -1/4(x - 2) - 2

Evaluate

y = -1/3x + 1/2 - 2

Evaluate the sum and the difference

y = -1/3x - 3/2

So, the equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2

Hence, the required equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2
