The measure of the angle of refraction is 22 degress, the correct option is A.

The angle made by a refracted ray with a perpendicular to the refracting surface.

Given

An incident ray of light strikes water at an angle of 30°.

The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.

In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.

The angle of the refraction is given by;

\(\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22\)

Hence, the measure of the angle of refraction is 22 degress.

Answer:

Step-by-step explanation:

Answer: HI = 5.3 cm

Let HI = x

GH = 2cm

m< H = 68 degrees

to find HI, we will need to apply the SOH CAH TOA RULE

HI = hypotenus

GH = adjacent

Cos 68 = adjacent / hypotenus

Cos 68 = 2 / x

Cross multiply

2 = x * cos 68

cos 68 = 0.3746

2 = x * 0.3746

Isolate x

x = 2/0.3746

x = 5.3cm

Therefore, HI is 5.3cm

The optimal price considering the fixed costs of $2,500 per night and the variable cost of $0.70 per hamburger.

To find the price of a hamburger that will maximize the nightly hamburger profit, we need to consider the fixed costs, variable costs, and price per hamburger.

Step 1: Identify the fixed and variable costs.
Fixed costs: $2,500 per night
Variable cost: $0.70 per hamburger

Step 2: Define the profit function.
Profit = (Price per hamburger * Number of hamburgers sold) - (Fixed costs + Variable costs * Number of hamburgers sold)

Step 3: Find the price elasticity of demand (PED).
To maximize profit, we need to find the price where PED = -1, meaning that a 1% change in price results in a 1% change in quantity demanded. Unfortunately, without further information on the demand function, it is not possible to determine the exact price that will result in PED = -1.

In summary, to find the price of a hamburger that will maximize the nightly hamburger profit, we need more information on the demand function to determine the price elasticity of demand. With that information, we can find the optimal price considering the fixed costs of $2,500 per night and the variable cost of $0.70 per hamburger.

From the provided data, we have

number of meatloafs = 5

Here we have need the cup measurements the number of meatloafs made per recipe and the net weight of canister.

net weight of the contents of 1 canister = 15 ounces

1 cup = 8 ounces

1.25 cups = 10 ounces

10 ounces of breadcrumbs makes 1 meatoafs.

but we made 5 meatloafs so, for 5 meatloaf needed breadcrumbs = 5×10

If we consider 4 canisters then

15ounces × 4 canisters = 60 ounces which are 10 more than the needed ( > 50 ounces.

and if we are consider 3 canisters then

15 ounces × 3 canisters = 45 ounces which is not enough.

So, we need 4 canisters of breadcrumbs and we will have 2/3 of a canister left over.

Step-by-step explanation:

Lets call the symbols Girl, Diamond, and Chest.

The second line has Diamond/Chest = 0

You can NEVER have zero on the bottom of a fraction. NEVER divide by 0. So this statement shows us that Diamond = 0

Now, look at the first statement.

Girl - Diamond = 5/7

Girl - 0 = 5/7

Girl = 5/7

We could use the third statement to find what the Chest equals. But let's skip it and save it to check our answer.

Look at the fourth statement.

Chest = 9/7 + Diamond

Chest = 9/7 + 0

Chest = 9/7

So far we found

Girl is 5/7 and

Chest is 9/7.

Do a check with the third statement.

2=Girl+Chest

2=5/7 + 9/7

2= 14/7

2= 2 That checks.

Lastly,

Chest - Girl = ?

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The given road rises 3 yards for every 16 yards measured on the surface of the road. We have to determine how far does a car travel horizontally when it travels 3.5 miles along the road. 1 mile = 1760 yards Therefore, 3.5 miles

= 3.5 × 1760 yards

= 6160 yards

A road rises 3 yards for every 16 yards measured on the surface of the road.We need to find the distance a car travels horizontally

=\((distance\,travelled\,horizontally)^2 + (distance\,travelled\,vertically)^2

= (distance\,travelled)^2\)Let the distance a car travels horizontally

= x

We know, the road rises 3 yards for every 16 yards measured  on the surface of the road. Therefore, the distance a car travels vertically

= \(\frac{3}{16}\) × distance a car travels horizontally

= \(\frac{3x}{16}\)

Using the Pythagorean Theorem,

=\(x^2 + \left(\frac{3x}{16}\right)^2

= (6160)^2\)\(x^2 + \frac{9x^2}{256}

= (6160)^2\)\(\frac{265x^2}{256}

= (6160)^2\)x²

= \(\frac{256 × 6160^2}{265}\)x

= \(\sqrt{\frac{256 × 6160^2}{265}}\)x

= 8926.03 yards

Therefore, the car travels 8926.03 yards horizontally when it travels 3.5 miles along the road. 1 yard = 0.000568182 miles

Therefore, the distance a car travels horizontally = 8926.03 × 0.000568182= 5.0761 miles (rounded to four decimal places) Hence, the car travels 5.0761 miles horizontally when it travels 3.5 miles along the road.

The distance traveled by the particle from t=0 to t=2 is e^2 - 1 units.

The particle moves in a straight line with velocity v(t) = e^t. To find the distance traveled by the particle from t=0 to t=2, we need to find the displacement of the particle in that time interval.

The displacement of the particle is given by the integral of the velocity function from t=0 to t=2:

∫v(t)dt = ∫e^tdt

Using the fundamental theorem of calculus, we can find the antiderivative of the velocity function and evaluate it at t=2 and t=0:

∫e^tdt = e^t |^2_0 = e^2 - e^0

The displacement of the particle from t=0 to t=2 is e^2 - e^0 = e^2 - 1.

Therefore, the distance traveled by the particle from t=0 to t=2 is e^2 - 1 units.

Here is an example of an answer using Hooke's law to determine the work done by a variable force in a spring problem: A force of 250 newtons stretches a spring 30 centimeters. How much work is done in stretching the spring from 10 centimeters to 40 centimeters?

The formula for Hooke's law is

F = kx

where, F is the force applied, x is the extension or compression of the spring from its equilibrium position, and k is the spring constant.

To determine the spring constant, we can rearrange the formula as follows:

k = F/x

We know that a force of 250 newtons stretches a spring 30 centimeters, so the spring constant is:

k = 250/30

  = 8.33 N/cm

To calculate the work done in stretching the spring from 10 centimeters to 40 centimeters, we can use the formula for work done by a variable force, which is given by the following formula:

W = 1/2k(x2^2 - x1^2)

where, W is the work done, k is the spring constant, x1 is the initial extension or compression of the spring, and x2 is the final extension or compression of the spring. In this case, x1 = 10 cm and x2 = 40 cm.

Therefore, the work done in stretching the spring from 10 centimeters to 40 centimeters is:

W = 1/2(8.33)(40^2 - 10^2)W  

   = 1/2(8.33)(1500)W

   = 6247.5 N-cm

Therefore, the work done in stretching the spring from 10 centimeters to 40 centimeters is 6247.5 N-cm.

To find the proportion of adjustable/ fixed ratios, you will need to divide the number of adjustable items by the total number of items. For example, if you have 8 adjustable items and 10 total items, the proportion of adjustable items is 8/10, or 0.8.

To find the proportion of adjustable/fixed ratios, you need to follow these steps:

1. Identify the adjustable and fixed ratios in the question.
2. Convert the adjustable and fixed ratios into fractions.
3. Find the common denominator of the two fractions.
4. Multiply both the numerator and denominator of each fraction by the common denominator.
5. Subtract the numerator of the fixed ratio fraction from the numerator of the adjustable ratio fraction.
6. Simplify the resulting fraction if necessary.

For example, if you have an adjustable ratio of 2:3 and a fixed ratio of 1:4, you would first convert these ratios into fractions, 2/3 and 1/4. Next, you would find the common denominator, which is 12. You would then multiply both the numerator and denominator of each fraction by 12, resulting in 8/12 and 3/12. Finally, you would subtract 3 from 8 to get 5, and simplify the resulting fraction to 5/12. Therefore, the proportion of the adjustable/fixed ratios is 5/12.

Answer:

A. y = -1/4x + 1 1/2

B. The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)

Step-by-step explanation:

A. Your equation is 2x + 8y = 12

so solve this for y like any other other question. Start by subtracting 2x from both sides: 8y = -2x + 12

then divide both sides by 8 to isolate y: y = -2/8x + 12/8

simplify your equation: y = -1/4x + 3/2

turn 3/2 into a mixed fraction: y = -1/4x + 1 1/2

The solution to the equation ϕ(n) = 42 is n = 42.

To solve the equation ϕ(n) = 42, where ϕ(n) represents Euler's totient function, we need to find the value of n. The totient function ϕ(n) gives the count of positive integers less than or equal to n that are coprime with n.

To find the value of n, we can start by understanding the properties of the totient function. The totient function ϕ(n) is multiplicative, which means that for two coprime positive integers a and b, ϕ(a * b) = ϕ(a) * ϕ(b). Additionally, for any prime number p, ϕ(p) = p - 1.

Since we need to find the value of n such that ϕ(n) = 42, we can try to express 42 as a product of distinct prime factors. 42 can be written as 2 * 3 * 7.

Now, let's consider the prime factors and their corresponding values of ϕ(p) - 1:
ϕ(2) = 2 - 1 = 1
ϕ(3) = 3 - 1 = 2
ϕ(7) = 7 - 1 = 6

To get ϕ(n) = 42, we need to combine the prime factors in such a way that the values of ϕ(p) - 1 multiply to give 42. One possible solution is n = 2 * 3 * 7 = 42.
