Answer:

[tex]y=\pm i \sqrt{7}[/tex]

Step-by-step explanation:

Given equation is [tex]\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{3^2}{(y^2-16)}[/tex]

Factor denominators then solve by making denominators equal

[tex]\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{3^2}{(y^2-16)}[/tex]

[tex]\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{9}{(y+4)\left(y-4\right)}[/tex]

[tex]\frac{y\left(y+4\right)-4\left(y-4\right)}{\left(y-4\right)\left(y+4\right)}=\frac{9}{(y+4)\left(y-4\right)}[/tex]

[tex]y\left(y+4\right)-4\left(y-4\right)=9[/tex]

[tex]y^2+4y-4y+16=9[/tex]

[tex]y^2=9-16[/tex]

[tex]y^2=-7[/tex]

take squar root of both sides

[tex]y=\pm \sqrt{-7}[/tex]

[tex]y=\pm i \sqrt{7}[/tex]

Hence final answer is [tex]y=\pm i \sqrt{7}[/tex].

Answer: hypothesis

Step-by-step explanation:

Answer:

The correct word is hypothesis.

Step-by-step explanation:

If a conditional statement is true and its HYPOTHESIS is true, then the conclusion is true.

The conditional statement is written in the following form -

If p is true, then q is true.

Here p is the hypothesis and q is the conclusion.

The opposite can be defined as - if the hypothesis is true and the conclusion is false, then the conditional statement is false.

Answer:

The maximum possible area of the triangle is 36 units²

Step-by-step explanation:

Let

x, y the legs of the right triangle

Applying the Pythagoras Theorem

[tex]12^{2}=x^{2}+y^{2}\\\\144=x^{2}+y^{2}[/tex]

[tex]y=\sqrt{144-x^{2}}[/tex] ----> equation A

The area of the right triangle is equal to

[tex]A=\frac{1}{2}xy[/tex] ----> equation B

substitute equation A in equation B

[tex]A=\frac{1}{2}x(\sqrt{144-x^{2}})[/tex]

Using a graphing tool

The vertex of the graph is a maximum

That means

The x-coordinate of the vertex is the value of x for the maximum possible area of the triangle

The y-coordinate of the vertex is the maximum possible area of the triangle

The vertex is the point (8.485,36)

see the attached figure

therefore

The maximum possible area of the triangle is 36 units²

pretty much by simply solving for "y".

Answer:

y = -3/2 x +3

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

3x+2y = 6

Subtract 3x from each side

3x-3x+2y = -3x+6

2y = -3x+6

Divide each side by 2

2y/2 = -3x/2 +6/2

y = -3/2 x +3

This is in slope intercept form where the slope is -3/2 and the y intercept is 3

Answer:

16cm

Step-by-step explanation:

To find the diameter we must first find the radius and multiply by 2.

The isosceles triangle that has the length of a leg to be 8cm and a vertex angle of [tex]120\degree[/tex] that has been circumscribed is shown in the attachment.

We draw a line from the vertex of the isosceles triangle that bisects the base through the center O of the circle.

This implies that [tex]m\angle OAC=60\degree[/tex].

Based on this [tex]m\angle ACO=60\degree[/tex] because the two radii are equal.

It follows that:[tex]m\angle AOC=60\degree[/tex] because sum of angles in a triangle must be 180 degrees.

This means that, triangle AOC is an equilateral triangle, hence all sides are equal.

One side of this equilateral triangle happens to be the side of the leg of the isosceles triangle which is 8cm.

It follows that, the radius of the circle is 8cm.

Therefore the diameter of the circle is 16cm

Answer: g(3)= -2

ANSWER

g(3)=-2

EXPLANATION

The given function is

[tex]g(r) = - 5r + 13[/tex]

We want to find g(3).

We substitute r=3 into the given function to obtain:

[tex]g(3) = - 5 \times 3 + 13[/tex]

Multiply out the first term

[tex]g(3) = - 15 + 13[/tex]

Simplify the result to obtain:

[tex]g(3) = -2[/tex]

284,000

(You would round up one because the number right before the thousands place is the hundred, which in our case, is above 4. As such, we are going to round up to 284,000.)

Hope I could help! :)

When rounding 283,657 to the nearest thousand, we look at the hundreds digit which is 6. Since it is greater than 5, we round up, resulting in a final rounded number of 284,000.

To round 283,657 to the nearest thousand, we look at the hundreds place to decide whether to round up or down. Since the hundreds digit is a '6' (which is greater than 5), we round up to the next thousand. Therefore, 283,657 rounded to the nearest thousand is 284,000.

Rounding rules dictate that if the digit to the right of the target rounding place is 5 or greater, we round up the target digit by one. In this case, we're rounding to the nearest thousand, so we look at the hundreds place which is a 6. Since it is greater than 5, we add one to the thousands place, changing 283,000 to 284,000, and set all the following digits to zero, giving us our final rounded number.

Answer: The answer to your question is C. (7*5) - (7*3)

Step-by-step explanation: because when you have an expression or equation in parentheses, you apply the distributive property to get rid of the parentheses:

The problem will now look like this:

[tex]7(5-3)= (7*5) - (7*3)[/tex]

And if they asked you for the answer in a whole number, it would be 14 because

7*5=35 and 7*3=21

35-21=14

So, therefore, the expanded form would be (7*5) - (7*3)

Answer:

Tj should write 5.75 hours on her time card.

Step-by-step explanation:

We have been given, Tj worked for 5 hours and 45 minutes.

We will convert 45 minutes to hours by dividing 45 by 60 as one hour has 60 minutes.

[tex]\frac{45 minutes }{60} \times\frac{hour}{minutes}[/tex]

=0.75 hours

Hence, Tj should write 5.75 hours on her time card.

Answer: [tex](2g+h)[/tex] and [tex](2g-h)[/tex]

Step-by-step explanation:

The area of a rectangle is obtained by multiplying its lenght by its width.

You know that the area of this rectangle is [tex]4g^2- h^2[/tex], then you need to apply the Difference of squares to find the dimensions of this rectangle.

Remember that the Difference of squares is:

[tex]a^2-b^2=(a+b)(a-b)[/tex]

Then, applying this, you get:

 [tex]4g^2- h^2=(2g+h)(2g-h)[/tex]

Therefore, now you know that the dimensions are:

[tex](2g+h)[/tex] and [tex](2g-h)[/tex]

the length and breadth of rectangle are [tex]2g - h[/tex] and [tex]2g + h[/tex] respectively

The given expression for the area of the rectangle is [tex]4g^2 - h^2[/tex]

This expression is a difference of squares, which can be factored using the formula: [tex]a^2 - b^2 = (a - b)(a + b)[/tex]

Now by comparing both equations we can factor as follows:

[tex]4g^2 - h^2 = (2g)^2 - h^2\\\\4g^2 - h^2 = (2g+h)(2g-h)[/tex]

We know that area of a rectangle is a product of its length and breadth so we can say that:

Length: 2g - h

Breadth: 2g + h

So, the length and breadth of rectangle are [tex]2g - h[/tex] and [tex]2g + h[/tex] respectively

well, the assumption is that is a rectangle, namely it has two equal pairs, so we can just find the length of one of the pairs to get the dimensions.

Answer:

16.4 ft

Step-by-step explanation:

We are given that Yvette measured the length of her driveway to be 5 meters long.

We have to find that which is equivalent to  given length in given options.

Measurement of length = 5 m

We know that 1 meter =3.28 foot

1 meter=1.09 yard

1 meter =39.37 inches

5 m= [tex]5\times 3.28=16.4  ft[/tex]

5 m=[tex]5\times .109=5.45 yard[/tex]

5 m=[tex]5\times 39.37=196.85 inches[/tex]

Hence, measurement of length =5 m =16.4 ft

Answer:

2(5+7)

Step-by-step explanation:

2 times any equation is 2(equation) and our equation is the sum of 5 and 7 which means 5 plus 7, therefore our equation is 2(5+7)

Answer

(5 + 7) · 2

Step-by-step explanation

If we take a look at PEMDAS or BEDMAS whichever one you were taught, multiplication comes before addition. (And unless you are in 2nd grade, you will know that "times" means multiplication, and sum is the result of an addition problem.)

P = Parentheses {|} B = Brackets/Parentheses

That means that anything in parentheses or brackets comes first, no matter what type of problem it is. So, if we add 5 and 7 and then multiply it by two and just rephrase that, we get 2 times the sum of 5 and 7.

Answer:

Step-by-step explanation:

mid point of hypotenuse of right angled isosceles triangle is equidistant from three vertices.

length of altitude=16/2=8

The question is incomplete, here is a complete question.

Triangle FGH is an isosceles right triangle with a hypotenuse that measures 16 units. An altitude, GJ, is drawn from the right angle to the hypotenuse.

What is the length of GJ?

A. 2 units

B. 4 units

C. 6 units

D. 8 units

Answer : The correct option is, (D) 8 units

Step-by-step explanation :

Given:

Length FH = 16 unit

As we know that a altitude between the two equal legs of an isosceles triangle creates right angles is a angle and opposite side bisector.

Thus,

Length FJ = Length HJ = [tex]\frac{16}{2}[/tex] = 8 units

As, the triangle is an isosceles. So, length GF = length GH = x unit

First we have to determine the value of 'x'.

Using Pythagoras theorem in ΔFGH :

[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]

[tex](FH)^2=(GF)^2+(GH)^2[/tex]

Now put all the values in the above expression, we get :

[tex](16)^2=(x)^2+(x)^2[/tex]

[tex]256=2x^2[/tex]

[tex]x^2=128[/tex]

[tex]x=8\sqrt{2}[/tex]

Thus, length GF = length GH = x unit = [tex]8\sqrt{2}[/tex]

Now we have to determine the length GJ.

Using Pythagoras theorem in ΔGJH :

[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]

[tex](GH)^2=(GJ)^2+(HJ)^2[/tex]

Now put all the values in the above expression, we get :

[tex](8\sqrt{2})^2=(GJ)^2+(8)^2[/tex]

[tex]128=(GJ)^2+64[/tex]

[tex](GJ)^2=128-64[/tex]

[tex](GJ)^2=64[/tex]

[tex]GJ=\sqrt{64}[/tex]

[tex]GJ=8[/tex]

Thus, the length of GJ is, 8 units.
