The range of the function N(t) is [20.25, ∞). The correct option is D.

A function's range is the set of possible output values. For example, the range of the function f(x)=x² on the domain of all real numbers (xR) is the non-negative real numbers, which can be written as f(x)0 (or [0,] in interval notation).

In this question, we have been given that an online streaming service that offers TV shows, documentaries, and movies charges an initial fee of $ 20.25 and an additional monthly membership fee of $3.75.

The total cost, N(t), for a member after t months can be expressed with the function N(t) = 3.75t + 20.25

As t is the number of months, t can take values from 0 to infinity.

For t = 0 years,

N(0) = 3.75(0) + 17.25

N(0) = 0 + 17.25

N(0) = $17.25

For x tends to ∞, the value of function would be ∞. The range will be (20.25,∞).

2. You can use the commutative property to write an equivalent expression : 1/2 + y

3. z cubed and 3z isn't equivalent expressions, because 3z is 3 times z, and z cubed is z times itself, 3 times.

4 and 5. The expressions 3(y+1) and 3y + 3 are equivalent for any values as they are the exact same expression.

(Break the bracket of 3(y+1), we get : 3(y+1) = 3.y + 3.1 = 3y +3)

6. 2(r+3) = 2.r + 2.3 = 2r + 6

Answer:

a = h/2 would be the answer.

Step;-

Find slope:-

m = rise/run = (16-8)/(8-4) = 8/4 = 2

Now,

y = mx + b

or, 8 = 2(4) + b

so, b = 0

So,

y = mx + b

or, h = 2a + 0

so, h = 2a

hence,a = h/2.

The sea sponges's height grows 2cm every 1 year, so you can write an equation to find the height at any age \(a = \frac{h}{2}\)

To convert 95 pounds to kilograms, you need to know the conversion factor between the two units. One kilogram is equal to approximately 2.205 pounds.

When measuring weight, there are different units of measurement that can be used such as pounds (lbs) and kilograms (kg). Pounds (lbs) are commonly used in the imperial system, which is primarily used in the United States, whereas kilograms (kg) are part of the metric system which is widely used in many countries around the world. To convert 95 pounds to kilograms, you would divide 95 by 2.205. So 95 pounds is roughly equal to 43.09 kg.

It's important to keep in mind that when converting measurements, it's important to be precise and use accurate conversion factors. Additionally, it's also important to consider the level of precision required for the task at hand. In general, pounds are mostly used in the US and the UK, while kilograms are primarily used in other countries. And is important to use the right unit of measurement depending on the context of the task or situation.

The temperature of the steam is 441.7 K.

A 1-m³ tank contains 2.1085 kg of steam at 0.6 MPa.

The gas constant, critical pressure, and critical temperature of steam are

R = 0.4615 kPa.m³/kg.K,

TCr = 647.1 K, and

PCr = 22.06 MPa.

Using data from the steam tables, let's find the temperature of the steam.

According to the steam table, the specific volume of the steam is 0.194 m³/kg at 0.6 MPa and 393.71 K. Since 1 m³ tank contains 2.1085 kg of steam, the total volume of steam is:

V = m/v

= (2.1085 kg)/(0.194 m³/kg)

= 10.8665 m³

The ideal gas equation of state is:

Pv = mRTor

T = PV/mR

Substituting the values we get:

T = (0.6 MPa)(10.8665 m³)/(2.1085 kg)(0.4615 kPa.m³/kg.K)

T = 441.7 K

Therefore, the temperature of the steam is 441.7 K.

Step-by-step explanation:

because of a formula i forgot what called w^2 is 9x21=189

sqrt of 189 is 13.75

The solution for question a is 0.7636. The solution for question b is 12.09 hours. The solution for question c is 0.9842. We can show the working in the following manner.

(a) To find the probability that a household views television between 5 and 11 hours a day, we need to find the area under the normal distribution curve between those two values.

We can do this by standardizing the values using the formula z = (x - μ) / σ, where x is the value we're interested in, μ is the mean, and σ is the standard deviation. Then we can use a standard normal distribution table or calculator to find the area.

For 5 hours of viewing: z = (5 - 8.35) / 2.5 = -1.34

For 11 hours of viewing: z = (11 - 8.35) / 2.5 = 1.06

Using a standard normal distribution table, we find that the area to the left of -1.34 is 0.0918, and the area to the left of 1.06 is 0.8554. So the area between -1.34 and 1.06 is:

0.8554 - 0.0918 = 0.7636

Therefore, the probability that a household views television between 5 and 11 hours a day is 0.7636.

(b) To find the number of hours of television viewing that a household must have in order to be in the top 3% of all television viewing households, we need to find the z-score that corresponds to the top 3% of the distribution. We can then use the formula z = (x - μ) / σ to solve for x.

Using a standard normal distribution table, we find that the z-score that corresponds to the top 3% of the distribution is approximately 1.88. Therefore:

1.88 = (x - 8.35) / 2.5

Solving for x, we get:

x = 1.88 * 2.5 + 8.35 = 12.09

Therefore, a household must view at least 12.09 hours of television per day to be in the top 3% of all television viewing households.

(c) To find the probability that a household views television more than 3 hours a day, we need to find the area under the normal distribution curve to the right of 3. We can use the same formula as in part (a) to standardize the value and then use a standard normal distribution table or calculator to find the area.

For 3 hours of viewing: z = (3 - 8.35) / 2.5 = -2.14

Using a standard normal distribution table, we find that the area to the left of -2.14 is 0.0158. So the area to the right of 3 is:

1 - 0.0158 = 0.9842

Therefore, the probability that a household views television more than 3 hours a day is 0.9842.

The length of the ribbon to the nearest tenth is 50.3 inches.

To find the length of the ribbon that surrounds the edge of a circular hat that has a radius of 8 inches, we can use the formula for the circumference of a circle.

The formula for the circumference of a circle is given by the following:

C = 2πr

Where C represents the circumference of the circle, π represents the constant value of pi which is approximately equal to 3.14, and r represents the radius of the circle.

Given that the circular hat has a radius of 8 inches, we can use this value to find the circumference of the circle.

Hence, we have: r = 8 inches

C = 2πr

C = 2π(8)C = 16π

The length of the ribbon that surrounds the edge of the circular hat is equal to the circumference of the circle. Therefore, the length of the ribbon is:16π ≈ 50.3 inches (to the nearest tenth)

ΔABC ~ ΔQPR by the Angle-Angle (AA) similarity theorem of two triangles

Step-by-step explanation:

The coordinates of the vertices are given as follows;

A = (1, 2), B =(9, 8), C = (1, 8)

P= (5, -3), Q = (-7, 6), R = (-7, -3)

The given dimensions of AB and PQ are 10, and 15 respectively

The, l lengths of the sides of triangles are found as follows;

\(l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}\)

For segment BC, we have;

B =(9, 8), C = (1, 8)

(x₁, y₁) = (9, 8), (x₂, y₂) = (1, 8), substituting gives;

Length BC = 8

For length CA, C = (1, 8) A = (1, 2)

(x₁, y₁) = (1, 8)

(x₂, y₂) = (1, 2)

The length found by substituting the values for (x₁, y₁), (x₂, y₂) in the length equation gives; Length CA = 6

Given that length  CA² + BC² = 8² + 6² = 64 + 36 = 100 = BA², we have by Pythagoras theorem, we have ΔABC is a right triangle

Similarly, for ΔQPR, we have;

Length QR, Q = (-7, 6), R = (-7, -3) = 9

Length PR, P= (5, -3), R = (-7, -3) = 12

QR² + PR² = 9² + 12² = 225 = 15² = PQ²

∴ ΔQPR is a right triangle

By comparing the ratio of the sides, we have;

cos(θ) = PR/PQ = 12/15 = 4/5, θ = cos⁻¹(4/5) = 36.9°

∠RPQ = 36.9°

sin(θ) = QR/PQ = 9/15 = 3/5

Similarly in triangle ΔABC, we have;

cos(θ) = BC/AB = 8/10 = 4/5

∠CBA = 36.9°

Therefore, ∠CBA ≅ ∠RPQ = 36.9°

Also ∠PRQ ≅ ∠BCA = 90° (Angle opposite hypotenuse side of right triangle

Therefore, ΔABC and ΔQPR are similar triangles by the Angle-Angle (AA) similarity theorem of two triangles.
