Now use the expression found in Part C for the distance between your eyes and the object at point O, and find the ratio of the apparent distance to the real distance, d/D. Remember that the apparent distance is the distance calculated by your eyes using the angle θa instead of the angle θw. Since we are dealing with small angles, you may use the approximation sin(x)≈x and asin(x)≈x.

Hello your question is incomplete attached below is the missing part of the  question

answer :  ( d / D )  =  [tex]n_{a}[/tex]

                                 [tex]n_{w}[/tex]

Step-by-step explanation:

Given data:

Apparent distance = distance calculated using angle ∅a

also applying the approximation ; sin(x) ≈ x  and  asin(x) ≈ x

Find the ratio of apparent distance to real distance (d / D )

Using the given data in the question the ratio of apparent distance to real distance ( d / D )  =  [tex]n_{a}[/tex]

                                 [tex]n_{w}[/tex]

where [tex]n_{a}[/tex] = index of refraction ( air )

           [tex]n_{w}[/tex] = index of refraction ( water )

Solve for x. (3x + 17) (8x - 46)​

Answers

Answer:-15

Step-by-step explanation:

The value of x in the given expression (3x + 17) (8x - 46)​ is -17/3 or 23/4

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, (3x + 17)(8x - 46)​, we need to find the value of x,

(3x + 17)(8x - 46)​

To find the value of x, equate the expression to 0,

(3x + 17)(8x - 46)​ = 0

3x+17 = 0

x = -17/3

or

8x-46 = 0

8x = 46

x = 23/4

Hence, the value of x is -17/3 or 23/4

The unit rate for peaches is $2.00 per pound. The unit rate for grapes is $2.50 per
pound. If you had $10 to spend, would you be able to buy a greater weight of
peaches or of grapes? Explain your answer.

Answers

Answer: A greater weight of peaches will be bought

Step-by-step explanation:

The unit rate for peaches = $2.00 per pound.

The unit rate for grapes = $2.50 per

pound.

Amount to spend = $10

Weight of peaches to buy with $10 = $10 / $2.00

= 5 pounds

Weight of grapes to buy with $10 = $10 / $2.50

= 4 pounds

Therefore, a greater weight of peaches will be bought as 5 pounds will be bought instead of 4 pounds for grape.

Step-by-step explanation:

First, we need to get this in y=mx+b form.

m=slope

b=y axis intercept

8x+6y+1=0

8x+6y=-1

6y=-8x-1

[tex]y=-\frac{4}{3}x-\frac{1}{6}[/tex]

now that we have it in y=mx+b form, we know the slope. For the new equation, the slope will be the same and the only thing we don't know is the y axis intercept, so we'll have to solve for it.

Answers

Answer:

3a² + 3b² - 20ab

Step-by-step explanation:

Sum of 12ab-10b²-18a² and 9ab+12b²+14a²

12ab - 10b² - 18a² + 9ab + 12b² + 14a²

= 14a² - 18a² + 12b² - 10b² + 12ab + 9ab

= -4a² + 2b² + 21ab

Sum of ab + 2b² and 3b²- a²

= ab + 2b² + 3b²- a²

= -a² + 2b² + 3b² + ab

= -a² + 5b² + ab

Subtract

-a² + 5b² + ab - (-4a² + 2b² + 21ab

A grocery store sells a bag of 7 oranges for $2.80. What is the unit cost?

Answers

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

The sum of the interior angles of each polygon is 360°. In the diagram ABCD=HGEF find the values of x and y look at photo below

Answers

Answer:

x = 3

y = 60°

Step-by-step explanation:

The given parameters of the figures are;

The sum of the interior angles of each polygon (quadrilaterals) = 360°

Quadrilateral ABCD = Quadrilateral HGEF

∴ ABCD ≅ HGEF

Therefore;

Segment AB ≅ Segment HG, by Corresponding Sides of congruent polygons are congruent

∴ The length of segment AB = 3 ft. = The length of segment HG = x ft.

∴ 3 ft. = x ft.

x = 3

Similarly, we have;

∠A + ∠B + ∠C + ∠D = 360° Given

∠B = 100°, and ∠D = 70° Given

∴ ∠A + ∠C = 360° - (∠B + ∠D) = 360° - (100° + 70°) = 190°

∠A + ∠C = 190°

∠A ≅ ∠G and ∠C ≅ ∠E Corresponding angles of congruent polygons are congruent

∴ ∠A = ∠G and ∠C = ∠E By definition of congruency

∴ ∠A + ∠C = ∠G + ∠E = 190° by transitive property

∠G = (2·y + 2)°, and ∠E = (y + 8)° Given

∴ ∠G + ∠E = (2·y + 2)° + (y + 8)° = (3·y + 10)° = 190°

3·y = 190° - 10° = 180°

y = 180°/3 = 60°

y = 60°

The value of x and y are 3 feet and 72 degrees respectively

Angle in a quadrilateral.

From the given quadrilaterals, the sum of adjacent angles is 180 degrees.

Hence from figure;

m<E + m<F = 180m<B = m<F = 100

y + 8 + 100 = 180

y + 108 = 180

y = 180 - 108

y = 72degrees

Similarly;

m<D = mG = 70 degrees.

AB = GH = 3 feet

Hence the value of x and y are 3 feet and 72 degrees respectively

b. The two numbers are 8 and 10.

What is an integer ?

An integer is a number which has no decimal value.

According to the given question we have to write an equation representing the fact the product of two consecutive even integers is 80.

Let us represent the smaller integer x and the greater integer by (x+2).

As even numbers comes after every 2 digits.

∴ x(x+2) = 80

x² + 2x = 80

x² + 2x - 80 = 0

x² + 10x - 8x - 80 = 0

x(x+10) - 8(x+10) = 0

(x+10) = 0 OR (x-8) = 0

x = -10 OR x = 8.   ( x = 8 is the valid option as it satisfies the given equation)

The two integers are 8 and 10.
