The cost to charge an electric car's home battery charger is $3.355 (to the nearest penny).

The cost to charge an electric car's home battery charger can be calculated using the following equation:

Cost = (kW x hours x rate)

Where kW stands for kilowatts, hrs stands for hours and rate stands for the rate per kilowatt-hour.

In this case, we have: kW = 6.1, hrs = 11 and rate = $0.05

Therefore, Cost = (6.1 x 11 x 0.05) = $3.355

Therefore, it will cost $3.35(to the nearest penny) to charge the car's battery.

To calculate this cost, we first multiply the kW (6.1) by the hours (11) to get the total kWh used (67.1). We then multiply this number by the rate ($0.05) to get the total cost of charging the battery ($3.355). This cost is to the nearest penny as we rounded up to the nearest cent when multiplying the kWh by the rate.

The linear approximation of [tex]f(x) = x^2 at x = 3.5 is f(3.5)[/tex]  ≈ 9.5.

To write a linear approximation (equation of the tangent) and use it to approximate the value of a function, we can follow these steps:

Choose a point on the function where you want to approximate the value.

Let's call this point (a, f(a)).

Find the slope of the tangent line at that point using the derivative of the function at that point.

The slope of the tangent line is equal to the derivative of the function at that point, which is denoted by f'(a).

Write the equation of the tangent line using the point-slope form, which is given by: y - f(a) = f'(a)(x - a)

Use this equation to approximate the value of the function at a nearby point.

Plug in the value of x that is close to a into the equation and solve for y. The resulting y-value will be an approximation of the value of the function at the nearby point.

For example, suppose we want to approximate the value of [tex]f(x) = x^2 at x = 3.[/tex]

We can follow these steps:

Choose the point (3, f(3)) = (3, 9) on the function.

Find the slope of the tangent line at x = 3 using the derivative: f'(x) = 2x, so f'(3) = 6.

Write the equation of the tangent line using the point-slope form: y - 9 = 6(x - 3), which simplifies to y = 6x - 9.

Use this equation to approximate the value of f(x) at x = 3.5: f(3.5) ≈ 6(3.5) - 9 = 9.5.

Hello and Greetings Brainly users.

This is an exercise in "Equation of the line that passes through two points". The equation of a line is a mathematical formula used to describe a straight line in a Cartesian plane.

To find the equation of a line that passes through two points, you must first calculate the slope using the formula: m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the given points. Then, the point-slope form of the equation of the line is used to obtain the equation of the line: y - y₁ = m(x - x₁).

By solving this equation, we can obtain the equation of the line that passes through two points. If the slope of the line is zero, as in the case of two points lying on the same horizontal line, then the equation of the line is simply a horizontal line at y = k, where k is the y-coordinate of the points.

Applying the following formula:

m = (y₂ - y₁) / (x₂ - x₁)

where m is the slope of the line.

We find that the points are:

x₁ = 6 ,   y₁ = 4

x₂ = -5 , y₂ = 4

We substitute the data in the formula and solve:

m = (y₂ - y₁) / (x₂ - x₁)

m = (4 - 4)/(-5-6)

m = 0/-11

m = 0

Now, we can use the point-slope form of the equation of the line to obtain the equation of the line:

Where m = 0 and (x₁, y₁) is one of the two given points. We can choose any of the two points, but for this we will choose (6,4).

So, substituting the values we have, we have:

y - 4 = 0(x - 6)

Simplifying, we arrive at:

y - 4 = 0

y = 4

The equation of the line that passes through the points (6,4) and (-5,4) is y = 4 , since it is a horizontal straight line through the values of y = 4.

Step-by-step explanation:

There are many possible algebraic expressions involving c and d that are worth 24, but two possibilities are:

Two angles are coterminal if they share the same terminal side when drawn in standard position. In other words, coterminal angles differ by an integer multiple of 360 degrees.

To see if 90 degrees and -270 degrees are coterminal, we can add 360 degrees to the smaller angle (-270 degrees) and see if we get the other angle:

-270 + 360 = 90

The total revenue between the two companies is $3,200

To find the Nash Equilibrium, we need to look for a situation where neither firm has an incentive to change their strategy. This occurs when both firms are charging a price of $8 per month and each has 200 customers, resulting in total revenue of $3,200.

At this price and quantity, neither firm can increase their revenue by changing their strategy. If Netflix were to increase its price above $8, some of its customers would switch to Flixbuster, and Netflix's revenue would decrease. Similarly, if Flixbuster were to decrease its price below $8, it would gain customers from Netflix, but its revenue would still decrease.

Therefore, the Nash Equilibrium in this scenario is a price of $8 and 200 customers for each firm, resulting in total revenue of $3,200 between the two companies.

In mathematical terms, the Nash Equilibrium is a solution to the following system of equations:

Qn = 300 - P

Qf = 300 - P

TRn = P(Qn)

TRf = P(Qf)

where Qn and Qf are the quantities demanded by Netflix and Flixbuster, respectively, P is the price, and TRn and TRf are the total revenues earned by Netflix and Flixbuster, respectively. Solving this system of equations, we get P = 8 and Qn = Qf = 200, which results in total revenue of $3,200.

The speed of boat is 5/6 meter per second and height of boat is 50[tex]\sqrt{3}[/tex] meter.

An angle is a shape created by two rays or lines that meet at the same terminal. The Latin word "angulus" (which means "corner") is where the term "angle" first appeared. The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle. It is not necessary for the angle to be in Euclidean space if it lies in the plane. Angles are referred to as dihedral angles if they are created by the intersection of two planes in a space other than Euclidean. The sign "" is used to denote angles. The Greek letter,,, etc. can be used to represent the angle between the two beams.

The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

The speed of the boat from point C to point B is approximately 10.82 meters per second.

What is speed ?

Speed is a measure of how fast an object is moving. It is the rate at which an object covers distance.

We can use trigonometry to solve for h and the speed of the boat. Let's start with h:

From the right triangle CLB, we have:

tan 30° = h / CB

where CB is the distance between points C and B, which is given as 50 meters. Solving for h, we get:

h = CB * tan 30° = 50 * tan 30° ≈ 28.87 meters

So the height of the lighthouse is approximately 28.87 meters.

Now let's find the speed of the boat. We know that the boat travels from point C to point B in 1 minute, which is equivalent to 60 seconds. Let's define the speed of the boat as v, in meters per second. Then we have:

v = CB / t

where t is the time it takes for the boat to travel from point C to point B. We can find t using the distance formula:

[tex]CB = \sqrt{(x_B - x_C)^2 + (y_B - y_C)^2[/tex]

where x and y are the coordinates of each point. From the diagram, we can see that:

[tex]x_C = 0[/tex]

[tex]y_C = 0[/tex]

[tex]x_B = BL * cos \theta[/tex]

[tex]y_B = BL * sin \theta[/tex]

where BL is the distance from point B to the foot of the lighthouse, which is equal to h / tan θ. Therefore:

CB [tex]= \sqrt{((BL * cos \theta)^2 + (BL * sin \theta)^2)[/tex]

     [tex]= \sqrt{(BL^2 * (cos^2 \theta + sin^2 \theta))[/tex]

     [tex]= BL = h / tan \theta[/tex]

Substituting the values we have found, we get:

v = CB / t = (h / tan θ) / 60 ≈ 10.82 meters per second

Therefore, the speed of the boat from point C to point B is approximately 10.82 meters per second.

Given that the time between arrivals of vehicles at a particular intersection follows an exponential probability distribution with a mean of 14 seconds.

We know that the exponential probability distribution function is given by

f(x) = λ e^(-λx)

Where λ is the rate parameter of the distribution and is equal to 1/mean in this case. So, λ = 1/14.

Now, we need to find the probability that the arrival time between vehicles is 12 seconds or less. Mathematically, we can express this as:

P(X ≤ 12) = [tex]\int\limits^{12}_0[/tex] λ e^(-λx) dx

Integrating this expression, we get:

P(X ≤ 12) = [-e^(-λx)]_[0,12] = -e^(-λ12) + e^(-λ0)

Since e^(-λ×0) is equal to 1, we have:

P(X ≤ 12) = 1 - e^(-λ×12)

Substituting the value of λ, we get:

P(X ≤ 12) = 1 - e^(-12/14)

Answer:

10 oranges

Step-by-step explanation:

We Know

A grocery store sells a bag of 6 oranges for $4.80

4.80 / 6 = $0.80 for one orange

If Austin spent $8.00 on oranges, how many did he buy?

We Take

8 / 0.80 = 10 oranges

So, he bought 10 oranges.

Answer: Either 58 or 85

Step-by-step explanation:

5 + 8 = 13
8 + 5 = 13

5 x 8 = 40

8 x 5 = 40

Answer:

To the nearest hundredth of a percent, an interest rate of 6.68% would be required for Deondra to end up with $82,000 after 5 years of compounding interest.

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where:

A = the final amount (in this case, $82,000)

P = the principal (the initial investment, in this case, $64,000)

r = the interest rate (what we're trying to find)

n = the number of times the interest is compounded per year (in this case, 4, since it's compounded quarterly)

t = the number of years (in this case, 5)

Plugging in the values we know and solving for r, we get:

$82,000 = $64,000(1 + r/4)^(4*5)

$82,000/$64,000 = (1 + r/4)^20

1.28125 = (1 + r/4)^20

Taking the 20th root of both sides, we get:

(1.28125)^(1/20) = 1 + r/4

0.0167 = r/4

r = 0.0668 (rounded to four decimal places)

Therefore, to the nearest hundredth of a percent, an interest rate of 6.68% would be required for Deondra to end up with $82,000 after 5 years of compounding interest.

The correct equations for x = - 2 and x = 2 are,

⇒ x = ± 2

⇒ x² = - 4

⇒ x = ±2i

⇒ 3x² + 12 = 0

⇒ x² + 4 = 0

⇒ x = ±2i

⇒ 4x² = 16

⇒ x² = 4

⇒ x = ±2

⇒ 2 (x - 2)² = 0

⇒ (x - 2)² = 0

⇒ x = 2, 2

Thus, The correct equations for x = - 2 and x = 2 are,

⇒ x² - 4 = 0

⇒ 4x² = 16

The surface area of the prism is 78 square units, which corresponds to option A.

You provided three dimensions: 5 units, 3 units, and 3 units. I assume these are the dimensions of a rectangular prism.

Let's label the dimensions: length (l) = 5 units, width (w) = 3 units, and height (h) = 3 units.

There are two bases, and their areas are equal:

Base Area = l * w = 5 * 3 = 15 square units

There are also three pairs of lateral faces. The areas of the lateral faces are:

Two faces with dimensions l and h: 2 * (l * h) = 2 * (5 * 3) = 30 square units

Two faces with dimensions w and h: 2 * (w * h) = 2 * (3 * 3) = 18 square units

Now, add the areas of all the faces together:

Surface Area = Base Area * 2 + Lateral Area = 15 * 2 + 30 + 18 = 30 + 30 + 18 = 78 square units

So, the surface area of the prism is 78 square units, which corresponds to option A.
