Ryan is buying a triangular tract of land. The triangle has a base of 100 yards and a height of 30 yards. What is the area of the tact to land? HELPPPP PLZZZ

Answer:

Part A) The perimeter of the court is [tex]P=139.25\ ft[/tex]

Part B) [tex]5\ cans[/tex]

Step-by-step explanation:

Part A) we know that

The perimeter of the court is equal to the perimeter of the square plus the perimeter of semicircle

[tex]P=4D+\frac{\pi D }{2}[/tex]

we have that

[tex]D=25\ ft[/tex]

substitute

[tex]P=4(25)+\frac{(3.14*25)}{2}[/tex]

[tex]P=139.25\ ft[/tex]

Part B)

Find the area above the foul line (labelled II)

The area of a semicircle is equal to

[tex]A=\frac{\pi r^{2}}{2}[/tex]

we have

[tex]r=25/2=12.5\ ft[/tex]

substitute

[tex]A=\frac{(3.14)(12.5)^{2}}{2}[/tex]

[tex]A=245.31\ ft^{2}[/tex]

Round to the nearest whole number

[tex]A=245\ ft^{2}[/tex]

[tex]\large\boxed{B.\ 4x^2-41x+105}[/tex]

Step-by-step explanation:

[tex]f(x)=4x-\sqrt{x}\\\\g(x)=(x-5)^2\\\\f(g(x))\to\text{put}\ x=(x-5)^2\ \text{to}\ f(x):\\\\f(g(x))=f\bigg((x-5)^2\bigg)=4(x-5)^2-\sqrt{(x-5)^2}\\\\\text{use}\\(a-b)^2=a^2-2ab+b^2\\\sqrt{x^2}=|x|\\\\f(g(x)=4(x^2-2(x)(5)+5^2)-|x-5|\\\\x>5,\ \text{therefore}\ x-5>0\to|x-5|=x-5\\\\f(g(x))=4(x^2-10x+25)-(x-5)\\\\\text{use the distributive property:}\ a(b+c)=ab+ac\\\\f(g(x))=(4)(x^2)+(4)(-10x)+(4)(25)-x-(-5)\\\\f(g(x))=4x^2-40x+100-x+5\\\\\text{combine like terms}\\\\f(g(x))=4x^2+(-40x-x)+(100+5)\\\\f(g(x))=4x^2-41x+105[/tex]

Answer: Option B

[tex]f(g(x)) = 4x^2 -41x + 105[/tex]

Step-by-step explanation:

We have 2 functions

[tex]f(x) = 4x -\sqrt{x}[/tex]

[tex]g(x) = (x-5)^2[/tex]

We must find [tex]f(g(x))[/tex]

To find this composite function enter the function g(x) within the function f(x) as follows

[tex]f(g(x)) = 4(g(x)) -\sqrt{(g(x))}[/tex]

[tex]f(g(x)) = 4(x-5)^2 -\sqrt{(x-5)^2}[/tex]

By definition [tex]\sqrt{a^2} = |a|[/tex]

So

[tex]f(g(x)) = 4(x-5)^2 -|x-5|[/tex]

Since x is greater than 5 then the expression [tex](x-5)> 0[/tex].

Therefore we can eliminate the absolute value bars

[tex]f(g(x)) = 4(x-5)^2 -(x-5)[/tex]

[tex]f(g(x)) = 4(x^2 -10x + 25) -(x-5)[/tex]

[tex]f(g(x)) = 4x^2 -40x + 100 -x+5[/tex]

[tex]f(g(x)) = 4x^2 -41x + 105[/tex]

The area is the length x the height.

Length = 11.40 cm

Height = 6.90 cm

Area = 11.40 * 6.90 = 78.66 cm^2

The answer is D.

Answer:

[tex]f(x)=log_ex[/tex]

Step-by-step explanation:

By definition, we can write ln instead of log. WHEN??

Whenever the base of the logarithm is the number "e".

Hence, when we have:

[tex]Log_e[/tex]

We can write it in shortcut as:

[tex]Log_e=ln[/tex]

Hence, ln x can also be written as [tex]Log_ex[/tex]

Fourth answer choice is right.

Answer:

[tex]f(x) = log_e(x)[/tex]

Step-by-step explanation:

[tex]f(x) = ln x[/tex]

For logarithmic function ln(x) the base of ln is 'e'

[tex]f(x) = log_3(x)[/tex]

The base of log is 3 . so it is not equivalent to [tex]f(x) = lnx[/tex]

[tex]f(x) = log_{10}(x)[/tex]

The base of log is 10 . so it is not equivalent to [tex]f(x) = lnx[/tex]

[tex]f(x) = log_b(x)[/tex]

The base of log is b . so it is not equivalent to [tex]f(x) = lnx[/tex]

[tex]f(x) = log_e(x)[/tex]

The base of log is e . so it is equivalent to [tex]f(x) = lnx[/tex]

Answer:

The radius is [tex]r=5\ cm[/tex]

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

so

[tex]m<C =(1/2)[arc\ AB][/tex]

[tex]m<C =90\°[/tex]

substitute

[tex]90\°=(1/2)[arc\ AB][/tex]

[tex]arc\ AB=180\°[/tex]

That means----> The length side AB of the inscribed triangle is a diameter of the circle

Applying Pythagoras Theorem

Calculate the length side AB

[tex]AB^{2}=AC^{2}+BC^{2}[/tex]

[tex]AB^{2}=8^{2}+6^{2}[/tex]

[tex]AB^{2}=100[/tex]

[tex]AB=10\ cm[/tex] -----> is the diameter

Find the radius

[tex]r=10/2=5\ cm[/tex] -----> the radius is half the diameter

Answer:

[tex]x^{\frac{5}{12} }[/tex]

Step-by-step explanation:

In the question given we use the law of exponents;

[tex](a^{b})^{c} = a^{bc}[/tex]

If a base a is raised to a power b and the entire expression raised to a power c, the resulting expression is simply equal to the base a raised to the product of the two exponents b and c, that is bc.

In the case given,

a = x

b = 5/8

c = 2/3

To simplify the expression we simply multiply b and c;

bc = 5/8 * 2/3

     = 5/12

The simplified expression is thus;

[tex]x^{\frac{5}{12} }[/tex]

Answer:

The correct answer is ((x⁵/⁸)²/³) = x⁵/¹²

Step-by-step explanation:

Points to remember:-

Identity

(xᵃ)ᵇ = xᵃᵇ

Here it is given that, ((x⁵/⁸)²/³)

To find the value of ((x⁵/⁸)²/³)

(5/8) * (2/3) =  (5 * 2) /(8 * 3) = 10/24 = 5/12

By using identity (xᵃ)ᵇ = xᵃᵇ we can write,

((x⁵/⁸)²/³) = x⁽⁵/⁸⁾ˣ⁽²/³⁾

= x⁵/¹²    

Therefore the correct answer is ((x⁵/⁸)²/³) = x⁵/¹²

Step-by-step explanation:

The formula for finding the volume of a rectangular prism (the cargo area of the truck is the shape of a rectangle in 3D; a rectangular prism) is V = (l)(w)(h); where l = length, w = width, and h = height.

First, substitute the known values into the equation:

l = 8.5

w = 6

h = 10.5

V = (8.5)(6)(10.5)

(Note: .5 = 1/2)

Now, all we need to do is simplify:

V = 535.5 ft³ OR 535 1/2 ft³

(Note: ft³ is the condensed form of cubic feet)

You can pick whichever form your test directs you to use. They are both the same value though.

Hope this helps!

The volume of the cargo area of the truck is 519.75 cubic feet.

The volume of the cargo area of the truck can be calculated by multiplying its length, width, and height. Given the dimensions in feet are:

Length = 8 1/2 feet = 8.5 feet = 8 + 1/2 feet

Width = 6 feet

Height = 10 1/2 feet = 10.5 feet = 10 + 1/2 feet

To find the volume, we convert the mixed numbers to improper fractions and then multiply:

Length in fractions = 8 + 1/2 = 17/2 feet

Width in fractions = 6 = 6 * 2/2 = 12/2 feet

Height in fractions = 10 + 1/2 = 21/2 feet

Now, multiply the dimensions to find the volume:

Volume = Length * Width * Height

Volume = (17/2 feet) * (12/2 feet) * (21/2 feet)

Volume = (17 * 12 * 21) / (2 * 2 * 2) cubic feet

Volume = 4158 / 8 cubic feet

Simplifying the fraction, we get:

Volume = 519.75 cubic feet

Answer:

A.

Step-by-step explanation:

First, let's define the types of numbers.

Real numbers: a value that represents a quantity along a continuous line

ex: 1, 5, -6, 0.125, 45.5258,

Integer: Zero, any positive or negative number

ex: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5....

Whole numbers: a number without fractions [not negative]

ex: 0, 1, 2, 3, 4, 5.....

Rational numbers: any number that can be expressed as the quotient or fraction

ex: 1, 2, 3, 4, 5

Irrational numbers: any number that can't be expressed at the quotient or fraction

ex: pi, [3.14.... (never ending decimal)]  square root of 2....

Based on this information, the false statment would be A. I believe, because

pi is a real number and it is an irrational number.

I hope this helps!!! :)

Answer:

x cannot equal -3, and x cannot equal -2

Step-by-step explanation:

Answer:

The excluded values of the rational expression are -3 and -2.

Step-by-step explanation:

If a ration function is defined as [tex]R(x)=\frac{p(x)}{q(x)}[/tex], then the excluded values of the rational function are those values for which q(x)=0.

The given rational expression is

[tex]\frac{x^2+2x-3}{x^2+5x+6}[/tex]

Factories the numerator and denominator.

[tex]\frac{x^2+3x-x-3}{x^2+3x+2x+6}[/tex]

[tex]\frac{x(x+3)-1(x+3)}{x(x+3)+2(x+3)}[/tex]

[tex]\frac{(x+3)(x-1)}{(x+3)(x+2)}[/tex]                .... (1)

Equate the denominator equal to 0.

[tex](x+3)(x+2)=0[/tex]

Using zero product property,

[tex]x+3=0\Rightarrow x=-3[/tex]

[tex]x+2=0\Rightarrow x=-2[/tex]

Therefore the excluded values of the rational expression are -3 and -2.

Cancel out the common factors of equation (1)

[tex]\frac{x - 1}{x + 2}[/tex] for (x≠-3)

It means x=-2 is vertical asymptote and x=-3 is hole.

A frequency polygon is a statistical tool used in mathematics to represent the distribution of data visually, much like a line graph, but specifically connected to a histogram. They are particularly helpful for interpreting continuous data and spotting trends within datasets.

Although the question seems to be incomplete, it appears to ask about the terminology used in mathematics, particularly pertaining to polygons. However, if we connect the dots with the provided reference, it seems the actual topic is 'frequency polygons' in the context of statistics. A frequency polygon is a graphical representation of data in statistics, where it's used to illustrate the distribution of a dataset and is similar to a line graph. It is typically made by connecting the midpoints of the tops of bars of a histogram with straight lines, making the data visually easy to interpret. By doing so, it helps in understanding how values are distributed over an interval and is often used to compare different sets of data on the same graph.

Continuous data can sometimes be difficult to analyze, but frequency polygons simplify this by offering a clear, visual interpretation. They are helpful in identifying trends and patterns in data which are not immediately obvious when looking at a table of values or a histogram alone.

Answer:

Here the slope is 2.

Step-by-step explanation:

The first step here is to solve for y.  This will lead us to the correct slope value.  Subtracting 4x from both sides, we get -2y = 7 - 4x.

Dividing both sides by -2, we get y = -7/2 + 2x.  The coefficient of x is the slope.  Here the slope is 2.

The slope of a line parallel to the line 4x - 2y = 7 is 2. This is calculated by modifying the given equation into the form y = mx + b and determining the value of 'm', which represents the slope, and parallel lines share the same slope.

To find the slope of a line parallel to the given line, 4x - 2y = 7, we first need to put the given equation in the standard form y = mx + b, where 'm' represents the slope of the line.

We can do this by isolating 'y' in the equation. So, 4x - 2y = 7 becomes 2y = 4x - 7. Then, we divide the entire equation by 2 to solve for 'y', which gives us y = 2x - 7/2. Thus, the slope 'm' of this line is 2.

Lines that are parallel to each other have the same slope, so the slope of the line parallel to the given line is also 2.
