Which of the following could be the ratio between lengths of the two legs of a 30-60-90 triangle

Answers

Answer:

E and F.

Step-by-step explanation:

Let the side opposite the smallest angle have a measurement of x (this is the shortest side).

The hypotenuse is twice the shorter side so the hypotenuses would be 2x in this case.

The long leg is square root of 3 times the short side or sqrt(3)x in this case.

So the ratio of long leg to short leg is [tex]\frac{\sqrt{3}x}{x}=sqrt(3):1[/tex]

and

the ratio of short leg to long leg is [tex]\frac{x}{\sqrt{3}x}=1:sqrt(3)[/tex].

The answer is not A that division is equivalent to 1:1.

B same reason as A.

C is not right because 1:sqrt(2) is not the same as 1:sqrt(3)

I bolded the reason in C so you can see why I said that.

You can also put these in your calculator and compare the decimals like so:

D gives us 0.816 approximately while  sqrt(3)/1 gives 1.73 and 1/sqrt(3) gives 0.58 approximately. 0.816 is neither one of those.

How about E?  1:sqrt(3) is exactly what one of our ratios say.

How about F?  sqrt(3)/3=0.58 so this is what one of our ratios is equivalent to.

So E and F are your answers.

The only correct options are: E. [tex]\(1 : \sqrt{3}\)[/tex] and F. [tex]\(\sqrt{3} : 3\)[/tex].

To determine the correct ratios between the lengths of the legs of a [tex]\(30^\circ\)-\(60^\circ\)-\(90^\circ\)[/tex] triangle, we first recall the properties of such a triangle:

Step 1: In a [tex]\(30^\circ\)-\(60^\circ\)-\(90^\circ\)[/tex] triangle, the side lengths are in the ratio [tex]\(1:\sqrt{3}:2\)[/tex], where:

The shortest leg (opposite the [tex]\(30^\circ\)[/tex] angle) has length (1).

The longer leg (opposite the [tex]\(60^\circ\)[/tex] angle) has length [tex]\(\sqrt{3}\)[/tex].

The hypotenuse has length (2).

Step 2: Identify the correct ratio between the legs:

The ratio of the shortest leg to the longer leg is [tex]\(1:\sqrt{3}\)[/tex].

Now, let's analyze the given options:

A. [tex]\(\sqrt{2} : \sqrt{2}\)[/tex]: This ratio simplifies to (1:1), which is incorrect for a [tex]\(30^\circ\)-\(60^\circ\)-\(90^\circ\)[/tex] triangle.

B. [tex]\(\sqrt{3} : \sqrt{3}\)[/tex]: This ratio simplifies to (1:1), which is incorrect for a [tex](30^\circ\)-\(60^\circ\)-\(90^\circ\)[/tex] triangle.

C. [tex]\(1 : \sqrt{2}\)[/tex]: This does not match the ratio [tex]\(1 : \sqrt{3}\)[/tex].

D. [tex]\(\sqrt{2} : \sqrt{3}\)[/tex]: This does not match the ratio [tex]\(1 : \sqrt{3}\)[/tex].

E. [tex]\(1 : \sqrt{3}\)[/tex]: This matches the correct ratio [tex]\(1 : \sqrt{3}\)[/tex].

F. [tex]\(\sqrt{3} : 3\)[/tex]: This does not match the ratio [tex]\(1 : \sqrt{3}\)[/tex].

Thus, the only correct options are: E. [tex]\(1 : \sqrt{3}\)[/tex] and F. [tex]\(\sqrt{3} : 3\)[/tex]

A pet store owner set the price of a bag of cat food at 50% above the cost. When it did not sell, the price was reduced by 20%, to $12.00. What was the original cost?

Answers

Answer:

60

Step-by-step explanation:

Answer:

$10.

Step-by-step explanation:

Let x represent the original cost of bag of cat food.

We have been given that a pet store owner set the price of a bag of cat food at 50% above the cost. So the cost of cat food would be x plus 50% of x.

[tex]x+\frac{50}{100}*x\rightarrow x+0.5x=1.5x[/tex]

We are further told that the price was reduced by 20%, when it did not sell. So price of cat food after reduction would be [tex]1.5x[/tex] minus 20 percent of [tex]1.5x[/tex].

[tex]1.5x-(\frac{20}{100}\times 1.5x)[/tex]

[tex]1.5x-(0.20\times 1.5x)[/tex]

[tex]1.5x-(0.3x)[/tex]

[tex]1.2x[/tex]

Since price after reduction was $12, so we will equate [tex]1.2x[/tex] with 12 as:

[tex]1.2x=12[/tex]

[tex]\frac{1.2x}{1.2}=\frac{12}{1.2}[/tex]

[tex]x=10[/tex]

Therefore, the original cost of cat food was $10.

If f(x) = 4 - x^2and g(x) = 6x, which expression is equivalent to (g-f)(3)?

Answers

Answer:

(g-f)(3) = 23

Step-by-step explanation:

f(x) = 4-x^2

g(x) = 6x

we need to find g-f(3)

Put the value of x = 3 in g(x) and f(x) and subtract f(x) from g(x) i.e

(g-f)(3) = g(3) - f(3)

(g-f)(3) = 6(3) - {4-(3)^2}

(g-f) (3)=18-(4-9)

(g-f)(3) = 18-(-5)

(g-f)(3) = 18+5

(g-f)(3) = 23

so, (g-f)(3) = 23

Answer:

23

Step-by-step explanation:

(g-f)(3)=g(3)-f(3)

So we need to find g(3) and f(3). Then subtract.

g(3)=6(3)=18.

f(3)=4-(3)^2=4-9=-5.

(g-f)(3)=g(3)-f(3)=18-(-5)=18+5=23

Answers

The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2

Where the center point of the circle is (h,k) and r is the radius.

In the given equation 16 = r^2

To find r take the square root of both sides:

r = √16

r = 4

The answer is A.

Answer: OPTION A.

Step-by-step explanation:

The equation of a circle in center-radius form  is:

[tex](x - h)^2 + (y- k)^2 = r^2[/tex]

Where the center is at the point (h,k) and "r" is the radius.

Then, given the equation of the circle:

[tex](x - 3)^2 + (y + 1)^2 = 16[/tex]

You can idenfity that:

[tex]r^2=16[/tex]

Therefore, in order to find the radius, you need to solve for "r".

Give an example of a rational function that has a horizontal asymptote at y = 1 and a vertical asymptote at x = 4.

Answers

Answer:

Possibility 1: [tex]\frac{(x+1)(x+1)}{(x-4)(x+5)}[/tex]

Possibility 2: [tex]\frac{(x+1)(x+3)(x-3)}{x(x-4)(x+5)}[/tex]

Possibility 3: [tex]\frac{-4(x-4)(x+1)}{-4(x-4)(x-4)}[/tex]

There are infinitely many more possibilities.

Step-by-step explanation:

So we are looking for a fraction in terms of x.

We have a horizontal asymptote so that means the degree of the top has to equal to degree of the bottom. It is also at y=1 which means the coefficient of the leading term on top and bottom must be the same (but not zero) since the same number divided by the same number is 1.  

Now we also have a vertical asymptote at x=4 which means we need a factor of x-4 on bottom.

So there is a lot of possibilities. Here are a few:

Possibility 1: [tex]\frac{(x+1)(x+1)}{(x-4)(x+5)}[/tex]

You have the degrees are the same on top and bottom and the leading coefficients are the same.  You also have that factor of (x-4) on bottom.

Possibility 2: [tex]\frac{(x+1)(x+3)(x-3)}{x(x-4)(x+5)}[/tex]

Possibility 3: [tex]\frac{-4(x-4)(x+1)}{-4(x-4)(x-4)}[/tex]

Now a factor of (x-4) can be canceled here but you still have a factor of (x-4) left on bottom so you still have the vertical asymptote. You also still have the same leading coefficient on top and bottom (-4 in this case) and the same degree.

y = 3x - 1

Slope intercept form is written in this format:
y=mx+b

m represents the slope
b represents the y intercept

You can clearly see that line intercepts the y axis at -1 so if you substitute that in:

y = mx - 1

You can easily find the slope by following this simple formula: rise/run

If you start at (0, -1) and try to get to (1, 2) then you go up 3 units and across 1 unit so the slope is 3/1 or 3. It’s not a negative slope since the line goes upwards and not downwards.

If you substitute the slope and y intercept you get:

y = 3x - 1

~~hope this helps~~

For this case we have that the equation of a line of the slope-intersection form is given by:[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut-off point with the y axis

To find the slope we look for two points through which the line passes:

We have to:

[tex](x1, y1) :( 1,2)\\(x2, y2): (- 1, -4)[/tex]

Thus, the slope is:

[tex]m = \frac {-4-2} {- 1-1} = \frac {-6} {- 2} = 3[/tex]

We have then:

[tex]y = 3x + b[/tex]

Substituting a point in the equation to find b:

[tex]2 = 3 (1) + b\\2 = 3 + b\\b = 2-3\\b = -1[/tex]

Lu-yin predicts that 80% of the people she invites to her party will come. If she wants to have at least 20 guests, how many people should she invite to her party?

Answers

Answer:

25

Step-by-step explanation:

Since she predicts that 80% of the invited people come, she needs to invite a number greater than 20, so that 80% of that number is 20.

Let the number of invited people be x.

80% of x must be 20.

80% * x = 20

0.8x = 20

Divide both sides by 0.8

x = 25

Answer: She should invite 25 people.

Check: Let's find 20% of 25. If it is 20, then 25 is correct.

80% of 25 = 0.8 * 25 = 20

Since 80% of 25 is 20, the answer, 25, is correct.

There are infinite numbers that added or multiplied will give the same answer. But, if the require this two numbers to be the same, then we need to solve the following equation to see what we found out:

x + y = x * y

Given that we want the numbers to be equal, then y=x.

x + x = x * x

2x = x^2

x^2 - 2x = 0

x(x-2) = 0

We find that NOT only x=2 meets this requirement but also x=0.

Therefore, there is another number that when added, multiplied or squared gives the same result. The other number is zero!

Answers

Answer:

The answer is C) 13.

Step-by-step explanation:

To find the hypotenuse (longest side) of a right triangle, you need to use the Pythagorean Theorem. The formula for the hypotenuse is a^2 + b^2 = c^2.

5^2 (five squared) equals 25, and 12^2 (twelve squared) equals 144.

25 + 144 = 169

Next, find the square root of 169. It is 13. 13 is the length of the hypotenuse.

I hope this helped! :)

In the right triangle ABC, the length of the AC is equal to [tex]13[/tex] units.

What is the right triangle?

" Right triangle is defined as a triangle with one of the interior angles with measure equals to [tex]90[/tex] degrees."

Pythagoras theorem,

(Hypotenuse)² = ( adjacent side)² + (opposite side)²

According to the question,

In the right triangle ABC,

Adjacent side 'BC' [tex]= 12[/tex] units

'AC' represents the hypotenuse of the right triangle

Substitute the value in the Pythagoras theorem we get,

C)The range but not the domain of the transformed function is the same as that of the parent function.
D)The domain but not the range of the transformed function is the same as that of the parent function.

Answers

Answer:

The domain but not the range of the transformed function is the same as that of the parent function ⇒ answer D

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) translated horizontally to the right  by h units,

 then the new function g(x) = f(x - h)

- The domain of a function is set of the values of x which make

  the function defined

- The range is the set values of y that corresponding with the domain

- The domain of the function f(x) = IxI is the set of all real numbers

∴ The domain of f(x) is {x : x ∈ R}

- The range of  the function f(x) = IxI is the set of all real numbers

  greater than or equal 0

∴ The range f(x) = {y : y ≥ 0}

∵ f(x) reflected across the x-axis, then it will be change to g(x) = -IxI

∴ All the y-coordinates of the point on the function will be change

  from positive values to negative values

∵ The rang of f(x) is {y : y ≥ 0}

∴ The range of g(x) is {y : y ≤ 0}

∵ After the reflection the function translated 6 units to the right

∴ The x will change to x - 6

∴ The function will be h(x) = -Ix - 6I

- There is no values of x make h(x) undefined, then its domain is

  set of all real number

∴ The domain of h(x) is {x : x ∈ R}

∵ The domain of f(x) is {x : x ∈ R}

∵ The range of h(x) is the same the range of g(x)

∴ The range of h(x) is {y : y ≤ 0}

- f(x) and h(x) have same domains and different ranges

∴ The correct statement is: The domain but not the range of the

   transformed function is the same as that of the parent function

Break the middle term:

First multiply the coefficient of first term by the constant.

4*5=20

Now find any two numbers whose product = 20 and whose sum is equal to the middle term.

20*1 = 20

20-1 = 19

Now break the middle term:

4x^2+20x-x-5

Now group the first two terms and last two terms:

(4x^2+20x)-(x+5)

Now take the common from each group.

4x(x+5)-1(x+5)

(4x-1)(x+5).

Thus the factors are (4x-1)(x+5).....

How many subsets does the set A have? A={-3,-2,-1,0,1,2,3}

Answers

Answer:

128

Step-by-step explanation:

You find the number of subsets of a set by using the formula [tex]2^{\text{ number of elements}[/tex].

We have 7 elements so that means we have [tex]2^{7}=128[/tex] subsets.

Final answer:

A set with 7 elements can have 128 subsets, as calculated using the equation 2^n, where n is the number of elements in the set.

Explanation:

In Mathematics, a subset is a portion of a set, including the empty set and the set itself. The number of subsets a set can have is calculated using the equation 2^n, where 'n' is the number of elements in the set. In this case, the set A includes 7 elements, therefore applying the equation we get: 2^7=128 subsets, which is the answer to your question.

For example, {-3, -1, 0} would be a subset of set A, as would {0, 1, 2}, {-2, 0, 2}, and so on. The complete set ({-3,-2,-1,0,1,2,3}) is also a subset, as is the empty set ({}).

Step-by-step explanation:

The parent function [tex]\sqrt[3]{x}[/tex] looks like the first image attached.

Using knowledge of transformations, numbers outside the radical move the graph up or down (vertically). A positive number moves the graph up; a negative number moves the graph down.

Numbers inside the radical move the graph left or right (horizontally). A positive number moves the graph left; a negative number moves the graph right.

In the first transformation [tex]\sqrt[3]{x} -3[/tex] the number is outside of the radical, meaning that the graph will move vertically. The 3 is negative, so the graph will move 3 units down.

The first transformation moves the parent graph 3 units down.

In the second transformation [tex]\sqrt[3]{x-3}[/tex] the number is inside the radical so the graph will move horizontally. The 3 is negative so the graph will move 3 units to the right.

The second transformation moves the parent graph 3 units right.

c)They will loose $215.

Step-by-step explanation:

From the question you should understand that;

The charge is $35 per lawnThe rental cost for aerating machine is $215The funds raised is the amount gained after aeration work minus the cost of renting the machine.

The equation that relates the fund raised and number of lawns aerated during a day is;

Let number of lawns aerated that day be l

The cost to aerate one lawn per day is $35

Cost to rent the aeration machine is $215

a)The equation is ;

[tex]=(l*35)-215[/tex]

=  $35l-$215

b)Money raised

number of lawns,l=26

Substitute in the equation

Amount=$35l-$215

=$(35×26)-$215

=$910-$215=$695

c)If the team were unable to aerate due to weather condition, they will incur a loss to to renting of the aeration machine.They will lose $215.This can be avoided by not renting the aeration machine when the weather conditions seems unfavorable for working.

If pentagon OPQRS is dilated by a scale factor of seven over four from the origin to create O'P'Q'R'S', what is the ordered pair of point P'?

Answers

Answer:

The ordered pair of P'=(-8.75, 5.25)

Step-by-step explanation:

To get the ordered pair of point P' you simply have to multiply the coordinates of P by scale factor of 7/4

P:(-5,3)

P'(x,y)= (-5* 7/4, 3*7/4)

P'(x,y) = (-35/4 , 21/4)

P'(x,y) = (-8.75, 5.25)..

Thus the ordered pair of P'=(-8.75, 5.25)....

Answer:

(−5.25, −3.5)

x = 40

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the triangle on the left and calculate the third angle

Subtract the sum of the 2 angles from 180

third angle = 180° - (75 + 50)° = 180° - 125° = 55°

Consider the triangle on the right

The third angle = 55° ( vertical angles )

Subtract the sum of the 2 angles from 180

x = 180 - (55 + 85) = 180 - 140 = 40

The only beverages with higher sales are carbonated soft drinks. Recent news stories have highlighted the fact that most bottled water comes from municipal water supplies (the same source as your tap water), although it may undergo an extra purification step called reverse osmosis. Imagine two tanks that are separated by a membrane that is permeable to water, but not to the dissolved minerals present in the water. Tank A contains tap water and tank B contains the purified water. In the reverse osmosis process, pressure is applied to the tap water tank to force the water molecules across the membrane into the pure water tank. Suppose that while the reverse osmosis system is running tank B becomes contaminated with salt water such that it ends up with a higher salt concentration than tank A. What would happen if the reverse osmosis system was turned off?
