The smallest possible perimeter of the triangle is, 72.4 inches.

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.

As given the longest side of an acute triangle measure 30 inches.

The two remaining sides' combined length must be longer than the opposite side.

The sum of the two remaining sides should be greater than 30 inches if the side is 30.

Assume the other two sides add up to 31 inches.

So, The perimeter of a triangle is equal to the sum of its three sides, which comes to 30 + 31 = 64 inches.

Consequently, the circumference must be greater than 64 inches.

Hence, based on the possibilities, the triangle's smallest conceivable perimeter is 72.4 inches.

Answer:

The rate of change, or slope, is 1/2.

To find the slope of a line, first, pick two points on the line and determine their coordinates. Then, determine the difference in y-coordinates of these two points (rise). After that, determine the difference in x-coordinates for these two points (run). Then you have your slope!

Sides XY and YZ are both equal to √45 units, therefore, triangle XYZ is an isosceles triangle.

If a triangle has two side lengths that are equal to each other, the triangle is called an isosceles triangle. Therefore, two of the sides of an isosceles triangle must be equal.

Given the vertices of triangle XYZ as:

X(0, 2)

Y(3, 8)

Z(6, 2).

Find the length of each side using the distance formula, [tex]\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex].

XY = √[(3−0)² + (8−2)²]

XY = √45

XZ = √[(6−0)² + (2−2)²]

XZ = √36

XZ = 6

YZ = √[(6−3)² + (2−8)²]

YZ = √45

The triangle has two equal sides YZ and XY, therefore it is an isosceles triangle.

Answer:

27 miles, 40.5 miles, and 47.25 miles

Step-by-step explanation:

9 miles in 2/3 hours. To get to a whole number, we can multiply by the reciprocal of 2/3, which is 3/2. 2/3*3/2=1. Now lets multiply 9 by 3/2. 9*3/2=13.5

We now have a unit rate which is 13.5 miles each hour.

Now lets solve for 2 hours.

13.5*2= 27 miles

Now lets solve for 3 hours.

13.5*3=40.5 miles

Now lets solve for 3.5

Let the number of weeks be x after which both boys have same weight.

Mike's weight after x weeks:

Tom's weight after x weeks:

Equate both expressions and solve for x:

Answer:

After 8 weeks, both boys weigh same.

Step-by-step explanation:

Forming the equation,

→ 200 - 2x = 160 + 3x

Now the value of x will be,

→ 200 - 2x = 160 + 3x

→ -2x - 3x = 160 - 200

→ -5x = -40

→ x = -40/-5

→ x = 40/5

→ [ x = 8 weeks ]

Hence, the value of x is 8.

Although square roots are generally taken to be positive, a square root can be negative as a negative number multiplied by a negative number is always positive.

Step-by-step explanation:

In general, when someone is asking for a square root, they are seeking the positive value. This is called the principal square root. However, square roots can also be negative. Thus, the number -6 can be a square root of the number 36, just not a principal square root. So the negative square root is the same number as the principal square root, but the negative version. The negative square "squared" will give the same positive result as the principal square root, for instance,

3⋅3=9 and −3⋅−3=9.

Answer: The correct answer is 0. Negative numbers don't really have any square roots since a square cannot be negative it can only be positive or a 0.

The equation of the circle C is x² + y² = 80 when it passes through the tangent points (-20, 0) and (0, 10).

Equation of circle:

Equation of the circle refer the position of a circle on a cartesian plane.

Given,

C is a circle with center the origin.

A tangent to C passes through the points (-20, 0) and (0, 10)

Here we need to find the equation of the circle C.

In order to find the equation of our line:

We have to identify the y-intercept which is (0,10).

Now, we need to find the gradient of our line which is:

Than can be calculated by,

=> (10 - 0) / (0- (-20))

=>  10/20 = 0.5

Now, the equation of our line is written as,

y = 0.5x + 10

But, here we know the center of our circle is the origin:

Which is in the following form:

=> x² + y² = r²

where r refers the radius

So, here we need the line to meet our circle at one point, we can substitute the equation for our straight line in for y.

Then the equation of the circle is written as,

=> x² + (0.5x + 10)² = r²

When we simplify it, then we get,

=> x² + (0.5x + 10)(0.5x + 10) = r²

Now, we can expand and simplify the brackets to leave us with:

=> 1.25x² + 10x + 100 = r²

=> 1.25x² + 10x + 100 - r² = 0

Here we know that this is a tangent and so it only meets the circle at one point.

So, this equation should only have one solution.

Then it can be written as,

=> b² - 4ac = 0

=> 10² - 4(1.25)(100 - r²) = 0

When we simplify this one then we get the value of

=> r² = 90

Therefore the equation of the circle is x^2 + y^2 = 80.

Step-by-step explanation:

The rule that describes the function is (c) Output = (0.5)(Input) + 1.5

The points on the coordinate plane are given as

(negative 1, 1), (1, 2), (3, 3), (5, 4)

Express as numbers

So, we have

(-1, 1), (1, 2), (3, 3), (5, 4)

Divide the input values by 2

So, we have

0.5(Input) => (-1/2, 1), (1/2, 2), (3/2, 3), (5/2, 4)

Add 1.5 to the input values

So, we have

0.5(Input) + 1.5 => (1, 1), (2, 2), (3, 3), (4, 4)

So, we have

Output = 0.5(Input) + 1.5

Hence, the equation is (c)Output = 0.5(Input) + 1.5

The rational function is of the form
f ( x ) = 50 ( x + 1 ) ( x - 2 ) / ( x - 5 ) ( x + 5 )

What is rational function equation?

A rational equation can be defined as an equation that involves at least one rational expression

A rational function is a function of the form f( x )=P( x ) / Q( x ) ,

f( x ) = P( x ) / Q( x ) , where P( x ) and Q( x ) are both polynomials.

A rational function f ( x )=P( x ) / Q( x )

f( x ) = P( x ) / Q( x ) may have a vertical asymptote

The domain is the set of all real numbers for which Q( x ) ≠ 0

Given data ,

The function has vertical asymptote at x = 5 and x = -5

So , the denominator of the fraction of rational function contains the terms (x - 5) and (x + 5)

The x intercept is at ( 2 , 0 ) and ( -1 , 0 )

The y intercept is at ( 0 , 4 )

So , the numerator of the fraction of the rational function contains the terms

( x- 2 ) and ( x + 1 )

So , the rational function is of the form

f ( x )=P( x ) / Q( x )

f ( x ) = A ( x + 1 ) ( x - 2 ) / ( x - 5 ) ( x + 5 )

Now , we have the y intercept at ( 0 , 4 )

So , f ( 0 ) = 4

Substituting the value of f ( 0 ) in the above equation , we have

4 = A ( 0 + 1 ) ( 0 - 2 ) / ( 0 - 5 ) ( 0 + 5 )

4 = A ( -2 ) / ( -25 )

4 = 2A / 25

Multiply 25 on both sides , we get

2A = 100

Divide by 2 on both sides , we get

A = 50

Therefore , the rational function becomes

f ( x ) = 50 ( x + 1 ) ( x - 2 ) / ( x - 5 ) ( x + 5 )

Hence , the rational function is of the form
f ( x ) = 50 ( x + 1 ) ( x - 2 ) / ( x - 5 ) ( x + 5 )

Z in terms of m and n is z = [tex]3^{m} -2^{n}[/tex]

Exponentiation is the process of expressing large numbers in terms of powers. That is, exponent refers to the number of times a number has been multiplied by itself. For example, 6 is multiplied by itself four times, yielding 6 6 6 6. This is written as [tex]6^{4}[/tex]. The exponent is 4 and the base is 6.

Given that 1000 to the power of m divided by 100 to the power of n

When powers of the equal base are divided, the same base is placed and the exponents are subtracted, which is an important mathematical property of powers.

Then, as powers of the same base, we can write 1000m and 100n:

1000m = [tex](10^{3})^{m}[/tex] = [tex]10^{3m}[/tex]

100n= [tex](10^{2)^{n} }[/tex] = [tex]10^{2n}[/tex]

Now we perform the division of powers of the same base (10)

103m/102n

= 103m-2n

The measure of angles are

The length of the hypotenuse of the right triangle = 11 inches

The length of the one leg = 10 inches

Then the length of the other leg is the square root of the sum of the hypotenuse square and one leg square

Then the equation will be

The length of the other leg = [tex]\sqrt{11^2-10^2}[/tex]

Therefore AC = 11 inches

AB = 10 inches

BC = 4.58 inches

What is an inverse function?

A function that "undoes" another function is called an inverse. In other words, if f(x) yields y, then y entered into the inverse of f yields the output x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹.
