If you are going to use the ASA postulate to prove these triangles congruent what additional information do you need?

Answer:

[tex]2x^\frac{5}{3} - 4y^\frac{3}{4}[/tex]

Step-by-step explanation:

Given equation:

[tex]\sqrt[3]{8x^5} - \sqrt[4]{256y^3}[/tex]

([tex](8x^5)^\frac{1}{3} - (256y^3)^\frac{1}{4} \\ (8^\frac{1}{3}  . x^\frac{5}{3} ) - (256^\frac{1}{4}. y^\frac{3}{4})\\ 2x^\frac{5}{3} - 4y^\frac{3}{4}[/tex] !

The initial equations of (3√8x^5) and (4√256y^3) are first changed to exponential form and then simplified to final forms of 6x^2√x and 64y respectively. The final simplified form of the entire equation therefore becomes 6x^2√x - 64y.

The given expression is (3√8x^5) - (4√256y^3). Lets breakdown and simplify each component firstly.

The first expression, 3√8x^5, can be written as 3*(8x^5)^(1/2). The number 8 can be expressed as 2^3 and x^5 as (x^2)^(5/2). So, 3√(8x^5) simplifies to 3*2x^2*√(x) = 6x^2√x.

For the second expression, 4√256y^3, can be written as 4*(256y^3)^(1/2). The number 256 can be expressed as 2^8 and y^3 as (y^2)^(3/2). So, 4√(256y^3) simplifies to 4*16y = 64y.

Now, putting these values back into the original equation, we get: 6x^2√x - 64y

25.8/1=593.4/23

593.4 is the answer

Final answer:

To find out how many miles a minivan will travel on 23 gallons of gas with an average of 25.8 miles per gallon, multiply the gallons by the mpg to get 593.4 miles.

Explanation:

To calculate the distance a minivan will travel on 23 gallons of gas when it averages 25.8 miles per gallon, we simply multiply the number of gallons by the miles per gallon (mpg).

The formula to use is:

Distance = Number of Gallons × Average Miles per Gallon

Using the given values:

Distance = 23 gallons × 25.8 mpg

We calculate:

Distance = 593.4 miles

Therefore, the minivan can travel 593.4 miles on 23 gallons of gas, assuming it maintains the average fuel economy of 25.8 miles per gallon.

Answer:

Angle 3 and angle 4 are linear pair

Step-by-step explanation:

* Lets revise the types of angles

- If two line intersected at a point, there are two types of

pairs of angles

- Two vertically opposite angles equal in measure

- Linear pair of angles their sum is 180°

* Now lets solve the problem

- There are two lines intersect each other at a point

- They formed between them 4 angles

- Angle 2 and angle 4 are vertical opposite angles, equal in measure

- Angle 1 and angle 3 are vertical opposite angles, equal in measure

∴ m∠2 = m∠4

∴ m∠1 = m∠3

- Angle 1 and angle 2 formed a line

∴ They are linear pair of angles

- Angle 3 and angle 4 formed a line

∴ They are linear pair, of angles

∵ m∠1 + m∠2 = 180°

∴ m∠3 + m∠4 = 180°

Step-by-step explanation:

Answer:

Yes, (0,4) is a solution

Step-by-step explanation:

We have to plug in 0 in x and 4 in y IN BOTH THE INEQUALITIES.

IF BOTH ARE TRUE, then the system of inequalities is TRUE.

Let's check:

y ≤ -3x+4

4 ≤ -3(0)+4

4 ≤ 4

Is 4 less than OR equal to 4? Yes. THis is satisfied.

Now, checking 2nd one:

y > x^2 + 3x - 2

4 > (0)^2 + 3(0) - 2

4 > -2

Is 4 greater than -2? Yes, it is. So this is satisfied as well.

Hence, (0,4) is a solution to the system of inequalities shown.

Answer:

Yes, it is the solution

Step-by-step explanation:

You are given the system of two inequalities

[tex]\left\{\begin{array}{l}y\le -3x+4\\ \\y>x^2+3x-2\end{array}\right.[/tex]

To check whether point (0,4) is the solution to this system, substitute x=0 and y=4 into each inequality:

1.

[tex]4\le -3\cdot 0+4\\ \\4\le 4 \ [\text{true}][/tex]

2.

[tex]4>0^2+3\cdot 0-2\\ \\4>0+0-2\\ \\4>-2\ [\text{true}][/tex]

Since the coordinates of the point (0,4) satisfy both inequalities, the point (0,4) is the solution to the system

Answer:

and

[tex]y=2x+1[/tex]

We equate both equations to get:

[tex]x^2-5x+7=2x+1[/tex]

[tex]x^2-5x-2x+7-1=0[/tex]

[tex]x^2-7x+6=0[/tex]

We split the middle term to get:

[tex]x^2-6x-x+6=0[/tex]

[tex]x(x-6)-1(x-6)=0[/tex]

[tex](x-6)(x-1)=0[/tex]

[tex](x-6)=0,(x-1)=0[/tex]

[tex]x=6,x=1[/tex]

When x=1, y=2(1)+1=3

The solutions are (6,13) and (1,3)

Answer:

a° = 80° , b° = 40° , c° = 40° , d° = 100°

Step-by-step explanation:

* Lets study the information in the question to solve it

- There is a circle and two chords of it are parallel

∵ The two chords are parallel

- The measure of b° is the same with the angle of measure 40°

   because they are alternate angles

∴ b° = 40°

- The vertex of the angle of measure 40° is on the circle

∴ This angle is inscribed angle subtended by the arc of measure a°

- There is a relation between the inscribed angle and its subtended arc,

 the measure of the arc is twice the measure of the angle

∵ The measure of the angle is 40°

∴ a = 40° × 2 = 80°

∴ a° = 80°

- In the circle any two inscribed angles subtended by the same arc

 are equal in measure

∵ The angle of measure 40° and the angle of measure c° are

  inscribed angles subtended by the same arc of measure a°

∴ c° = 40°

- The sum of the measures of the interior angles in any triangles is 180°

∴ b° + c° + d° = 180° ⇒ interior angles of a Δ

∵ b° = 40° , c° = 40°

∴ 40° + 40° + d° = 180° ⇒ add

∴ 80° + d° = 180° ⇒ subtract 80 from both sides

∴ d° = 100°

Answer:

19) sin 48° ≅ 0.7431

20) sin 38° ≅ 0.6157

21) cos 61° ≅ 0.4848

22) cos 51° ≅ 0.6293

Step-by-step explanation:

* Lets explain the meaning of trigonometry ratio

- In any right angle triangle:

# The side opposite to the right angle is called the hypotenuse

# The other two sides are called the legs of the right angle

* If the name of the triangle is ABC, where B is the right angle

∴ The hypotenuse is AC

∴ AB and BC are the legs of the right angle

- ∠A and ∠C are two acute angles

- For angle A

# sin(A) = opposite/hypotenuse

∴ sin(A) is the ratio between the opposite side of ∠A and the hypotenuse

# cos(A) = adjacent/hypotenuse

∴ cos(A) is the ratio between the adjacent side of ∠A and the hypotenuse

# tan(A) = opposite/adjacent

∴ tan(A) is the ratio between the opposite side of ∠A and the

  adjacent side of A

# The approximation to the nearest ten-thousandth, means look to

  the fifth number before the decimal point if its 5 or greater than 5

  ignore it and add the fourth number (ten-thousandth) by 1 if it is

 smaller than 5 ignore it and keep the fourth number as it

* Now lets solve the problems

19) sin 48° is the ratio between the side opposite to the angle of

    measure 48° and the hypotenuse of the triangle

∴ sin 48° = 0.74314 ≅ 0.7431 ⇒ to the nearest ten-thousandth

20) sin 38° is the ratio between the side opposite to the angle of

    measure 38° and the hypotenuse of the triangle

∴ sin 38° = 0.61566 ≅ 0.6157 ⇒ to the nearest ten-thousandth

21) cos 61° is the ratio between the side adjacent to the angle of

    measure 61° and the hypotenuse of the triangle

∴ cos 61° = 0.48480 ≅ 0.4848 ⇒ to the nearest ten-thousandth

22) cos 51° is the ratio between the side adjacent to the angle of

    measure 51° and the hypotenuse of the triangle

∴ cos 51° = 0.62932 ≅ 0.6293 ⇒ to the nearest ten-thousandth

Answer:

16 m < P < 19 m

Step-by-step explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x----> the length of the third side

Applying the triangle inequality theorem

1) 3+8 > c

11 > c

c < 11 m

2) c+3 > 8

c> 5 m

so

the measure of the third side must be

5 m < c < 8 m

therefore

The perimeter of the triangle is equal to

P=3+8+c

P=11+c

The inequality is equal to

(11+5) m < P < (11+8) m

16 m < P < 19 m

Answer:

Its diagonals are perpendicular, then it is a rhombus

Step-by-step explanation:

* Lets revise the properties of the parallelogram and the rhombus

- In the parallelogram each two opposite sides are parallel

- In the parallelogram each two opposite sides are equal in length

- In the parallelogram the diagonals bisect each other

- In the rhombus each two opposite sides are parallel

- In the rhombus all the sides are equal in length

- In The rhombus the diagonals are perpendicular to each other

- Parallelogram is a rhombus if two adjacent sides are equal in length

- Parallelogram is a rhombus if its two diagonals are perpendicular

* Now lets solve the problem

∵ The vertices of the parallelogram are

   A(-3 , 2) , B(-2 , 6) , C (2 , 7) , D (1 , 3)

- The slope of the line which passes through points (x1 , y1) and (x2 , y2)

  is m = (y2 - y1)/(x2 - x1)

* lets find the slopes of the sides and the diagonals

∵ The slope of AB = (6 - 2)/(-2 - -3) = 4/1 = 4

∵ The slope of BC = (7 - 6)/(2 - -2) = 1/4 = 1/4

∵ The slope of CD = (3 - 7)/(1 - 2) = -4/-1 = 4

∵ The slope of DA = (2 - 3)/(-3 - 1) = -1/-4 = 1/4

- The product of the slopes of the perpendicular line is -1

∵ AB and BC are two adjacent sides and the product of their slopes

  = 4 × 1/4 = 1 ≠ -1

∴ AB and BC are not perpendicular

∴ The parallelogram can not be a rectangle

- Lets check the slopes of the diagonals

∵ The diagonals of the parallelogram are AC and BD

∵ The slope of AC = (7 - 2)/(2 - -3) = 5/5 = 1

∵ The slope of BD = (3 - 6)/(1 - -2) = -3/3 = -1

∵ The product of the slopes of AC and BD = 1 × -1 = -1

∴ AC and BD are perpendicular

∴ ABCD is a rhombus

Answer:

x = -1.

Step-by-step explanation:

√(x + 10) - 4 = x

√(x + 10) = x + 4

Squaring both sides:

x + 10 = x^2 + 8x + 16

x^2 + 8x - x + 6 = 0

x^2 + 7x + 6 = 0

(x + 6)(x + 1) = 0

x = -6, -1.

Check for any extraneous roots:

√(x + 10) - 4 = x

Try x = -6:

√(-6 + 10) - 4 = 2 - 4 = -2.

but we found x = -6  , so -6 is not a root.

Try x = -1:

√(-1 + 10) - 4 = 3 - 4 = -1. So x = -1 is a root.

x=-1

Step-by-step explanation:

sqrt(x+10) -4= x

sqrt(x+10) = x+4

square each side

x+10=(x+4)^2

x+10= x^2+8x+16

subtract x+10 from each side

x^2+7x+6=0

(x+6)(x+1)=0

x=-6 x=-1

Then we plug both back into the equation.

sqrt(-1+10) -4= -1

sqrt(9) -4= -1

3-4 = -1

-1=-1. this works out.

sqrt(-6+10) -4 = -6

sqrt(4) -4= -6

2-4= -6

-2= -6. this does not work so the only solution is x=-1

Answer:

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

x ----> the area of the enlarged garden

y ----> the area of the original garden

[tex]z^{2}=\frac{x}{y}[/tex]

we have that

If Tessa multiplies each dimension by 2, then the scale factor equals 2.

[tex]z=2[/tex]

substitute

[tex]2^{2}=\frac{x}{y}[/tex]

[tex]4=\frac{x}{y}[/tex]

[tex]x=4y[/tex]

The area of the enlarged garden will be equal 4 times the area of the original garden

so

If Tessa wanted to have twice as much surface, she must multiply each dimension by a square root of 2.

therefore

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two.

Answer: No, his prediction is unreasonable. After 5 minutes, the number of cells would be 400, not 32. See the explanation below for details.

-------

Remember:

-------

Identify the given information.

[tex]a_{1}[/tex] = 25

[tex]r[/tex] = 2

Use the explicit formula for geometric sequences.

[tex]a_{n} = a_{1} r^{n - 1}[/tex]

Substitute the given values.

[tex]a_{n} = (25)(2)^{n - 1}[/tex]

Substitute in 5 for [tex]n[/tex] to find out how many cells there would be after 5 minutes.

[tex]a_{5} = (25)(2)^{5 - 1} \\\\a_{5} = (25)(2)^{4} \\\\a_{5} = (25)(16)\\\\a_{5} = 400[/tex]

Final answer:

The doctor's prediction of 32 cells after 5 minutes is not reasonable, because based on exponential growth of doubling every minute, 25 initial cells should grow to 800 cells in that time period.

Explanation:

The given question involves the calculation of cell numbers in a growing population, which relates to the field of exponential growth. Using the information provided that the number of cells doubles every minute, we can apply the formula for exponential growth, which is [tex]2^{n}[/tex], where 'n' is the number of generations or minutes in this case.

Starting with 25 cells, after 5 minutes, the expected number of cells would be calculated by multiplying 25 by 25 (since the cells double every minute). This calculation gives us 25 * 32, which equals to 800 cells after 5 minutes. Therefore, the doctor's prediction that there would only be 32 cells after 5 minutes is not reasonable, as the correct calculation suggests the number should be much higher.

Answer:

C. 17.3

Step-by-step explanation:

Using Pythagoras theorem

Divide the triangle into half

c^2=a^2+b^2

20^2=a^2+10^2

400=a^2+100

400-100=a^2

300=a^2

17.32=a^2

The height of the equilateral triangle to the nearest tenth is 17.3

Given that:

An equilateral triangle has sides of length 20.

Equilateral triangles are the type of triangles which has all the sides equal to each other.

That is, three sides will have equal length.

So all the side of the triangle is 20.

The height of the triangle is the perpendicular line drawn from any of these vertices.

Since this is an equilateral triangle, the height divides the base into equal lengths.

So each half will be 20/2 = 10.

Here, a right angle is formed.

Using Pythagoras theorem,

h = √(20² - 10²)

  = √(400 - 100)

  = √300

  = 17.3

Hence the correct option is C.

From the diagram, we can note that the diagonal of the tray represents the hypotenuse of a right-angled triangle having legs 9.5 in and 13 in

Therefore, to get the length of the hypotenuse, we can use the Pythagorean equation which is as follows:

c² = a² + b²

where c is the length of the hypotenuse and a and b are the length of the two legs

Substitute with the givens in the above equation to get the length of the hypotenuse as follows:

c² = (9.5)² + (13)² = 259.25

c = 16.1 in which is approximately 16 in

From the above, we can conclude that:

The longest bread stick that can be fit straight along the diagonal of the tray is approximately 16 in

Answer: 100mL

Step-by-step explanation:

A 15% alcohol solution contains 15mL alcohol in 100mL solution

In 400ml there will be 400mL·15/100 = 6,000mL/100 = 60mL alcohol

Let the volume of pure alcohol to be added V.

In the new solution there will be (60 + V)mL  alcohol

And the total volume will be (400 + V)mL

Concentration required 32% = 0.32

Concentration = (60 + V)mL/(400 + V)mL = 0.32

60mL + VmL = 0.32(400 + V)mL

60mL + VmL = 128mL + V·*0.32mL

VmL - V·0.32mL = 128mL - 60mL = 68mL

V(1 - 0.32)mL = 68mL

V·0.68mL = 68mL

VmL = 68mL/0.68 = 100mL ►  alcohol volume to be added

Answer : 100mL

Verification

New solution

There will be  400mL + 100mL = 500mL total volume
