The value of Emma's deposit after 3 years, including simple interest, is $90 + $10.80 = $100.80.

Simple Interest = Principal x Rate x Time

In this case, the Principal is $90 (the initial deposit), the Rate is 4% (0.04 as a decimal), and the Time is 3 years.

Step 1: Calculate the simple interest.
Simple Interest = $90 x 0.04 x 3
Simple Interest = $10.80

Step 2: Add the simple interest to the initial deposit.
Total Value = Principal + Simple Interest
Total Value = $90 + $10.80
Total Value = $100.80

So, the value of Emma's deposit after 3 years is $100.80.

Grass Seed Area = L - 20 1/8

To help Warren determine the area of his lawn where grass seed is needed, we first need to know the total area of his lawn.

Unfortunately, you have not provided the dimensions of the entire lawn. However, I can guide you through the process using the information given about the pool.

First, let's find the area of the pool. The dimensions are 5 3/4m by 3 1/2m. To find the area, multiply the length by the width:
Area = (5 3/4) * (3 1/2)
Convert the mixed numbers to improper fractions:
Area = (23/4) * (7/2)
Multiply the fractions:
Area = (23*7) / (4*2) = 161/8

Now convert the improper fraction back to a mixed number:
Area = 20 1/8 square meters
This is the area of the pool. To find the area where grass seed is needed, subtract the pool's area from the total area of the lawn. Assuming the total area of the lawn is "L" square meters, the area to be covered with grass seed would be:
Grass Seed Area = L - 20 1/8

Once you provide the dimensions of the entire lawn, you can follow these steps to find the area where grass seed is needed.

Given AB and AC are lines that are tangent to the circle with the measure of angle BAC = 40°, ∠BDC is 140°.

A tangent to a circle is a line that intersects the circle at a single point. The point at which the tangent intersects the circle is known as the point of tangency. The tangent is perpendicular to the circle's radius, with which it meets.

You've been handed two tangent lines. You will also be handed a four-sided figure. All four-sided figures have 360 degrees of rotation. At 90 degrees, a radius meets a tangent.

∠BDA = 90°

∠DCA = 90°

∠BCA = 40°

All the angles in total make 360°, so:

∠BDA + ∠DCA + ∠BCA + ∠BDC = 360

90 + 90 + 40 + ∠BDC = 360

220 + ∠BDC = 360

∠BDC = 360 - 220

Using the composition of functions, if the two functions are inverses of each other, therefore, we cannot conclude if f(x) and g(x) are inverses of each other.

To check if the two functions f(x) and g(x) are inverses of each other, we need to verify if their composition f(g(x)) and g(f(x)) results in the identity function f(x) = x.

Let's first find the composition f(g(x)):

f(g(x)) = f(x^2 - 4)

= sqrt(x^2 - 4) + 4

Now, let's find the composition g(f(x)):

g(f(x)) = g(sqrt(x) + 4)

= (sqrt(x) + 4)^2 - 4

= x + 16 + 8sqrt(x)

To check if f(x) and g(x) are inverses of each other, we need to check if f(g(x)) = x and g(f(x)) = x for all x in the domain of the functions.

For f(g(x)):

f(g(x)) = sqrt(x^2 - 4) + 4

This function is only defined for x > 2, since the square root of a negative number is not real. Therefore, the domain of f(g(x)) is (2, infinity).

For g(f(x)):

g(f(x)) = x + 16 + 8sqrt(x)

This function is only defined for x >= 0, since the square root of a negative number is not real. Therefore, the domain of g(f(x)) is [0, infinity).

Since the domains of f(g(x)) and g(f(x)) do not overlap, we cannot check if they are inverses of each other. Therefore, we cannot conclude if f(x) and g(x) are inverses of each other.

The mass of the lamina that occupies the region D is 31/2 units and the center of mass is located at (1/2, 2/e).

We can find the mass of the lamina by integrating the density function over the region D:

m = ∫∫D p(x,y) dA

where dA is the area element in polar coordinates, which is equal to r dr dθ. The region D can be described as 0 ≤ x ≤ 1 and 0 ≤ y ≤ e, so the integral becomes:

m = ∫0^1 ∫0^e 31y dy dx

Solving the integral, we get:

m = 31/2

To find the center of mass, we need to find the x-coordinate and y-coordinate separately:

x = (1/m) ∫∫D x p(x,y) dA

y = (1/m) ∫∫D y p(x,y) dA

For the x-coordinate, we have:

x = (1/m) ∫0^1 ∫0^e x(31y) dy dx

Simplifying, we get:

x = (1/m) ∫0^1 31/2 x dx

x = 1/2

For the y-coordinate, we have:

y = (1/m) ∫0^1 ∫0^e y(31y) dy dx

Simplifying, we get:

y = (1/m) ∫0^1 31/3 e^3 dx

y = (2/e)

Since f''(x) is always 0, f(x) is not concave upward on any interval.

On what interval is f concave upward?

The first derivative of f(x) is f'(x) = 6.
The second derivative of f(x) is f''(x) = 0.
The interval on which f(x) is increasing is when f'(x) > 0, which is when x is in the interval (-2,-5) U (1,60).
The interval on which f(x) is decreasing is when f'(x) < 0, which is when x is in the interval (-5,1).
The interval on which f(x) is concave downward is when f''(x) < 0, which is all values of x.
The interval on which f(x) is concave upward is when f''(x) > 0, which is no values of x.

To find the first derivative of f(x), we need to take the derivative of each term separately. The derivative of 3 is 0, the derivative of 6x is 6, and the derivative of -153 +3.2 is 0. Adding these up gives us f'(x) = 6.

To find the second derivative of f(x), we need to take the derivative of f'(x), which is a constant function. The derivative of a constant function is always 0, so f''(x) = 0.

To determine where f(x) is increasing, we need to find the values of x where f'(x) > 0. Since f'(x) is a constant function, it is always positive, so f(x) is increasing on the interval (-2,-5) U (1,60).

To determine where f(x) is decreasing, we need to find the values of x where f'(x) < 0. Since f'(x) is a constant function, it is always positive, so f(x) is decreasing on the interval (-5,1).

To determine where f(x) is concave downward, we need to find the values of x where f''(x) < 0. Since f''(x) is always 0, f(x) is concave downward on all values of x.

To determine where f(x) is concave upward, we need to find the values of x where f''(x) > 0. Since f''(x) is always 0, f(x) is not concave upward on any interval.

The possible dimensions of the rectangular prism are (2x + 3) cm, (x + 4) cm, and 4 cm, or (2x + 3) cm, 4 cm, and (x + 4) cm, where x is a measure in centimeters.

The polynomial 8x² + 44x + 48 represents the volume of a rectangular prism in cubic centimeters, where x is a measure in centimeters.

To find the possible dimensions of the box, we need to factor the polynomial into three factors that represent the length, width, and height of the rectangular prism.

First, we can factor out the greatest common factor of the polynomial, which is 4:

8x² + 44x + 48 = 4(2x² + 11x + 12)

Next, we can factor the quadratic expression inside the parentheses:

2x² + 11x + 12 = (2x + 3)(x + 4)

Therefore, the polynomial can be factored as:

8x² + 44x + 48 = 4(2x + 3)(x + 4)

To find the cube of a semimajor axis length (A), we need to raise the value to the third power, which is simply multiplying it by itself three times. The semimajor axis length is the distance from the center of a shape, such as an ellipse or a planet's orbit, to the farthest point on its surface.

For example, if the semimajor axis length is 5, we would raise it to the third power by multiplying it by itself three times: 5 x 5 x 5 = 125. So the cube of a semimajor axis length of 5 is 125.

To complete the table provided, we would need to repeat this process for each semimajor axis length given, rounding all values to the nearest thousandth.

(a) A vector v parallel to the line of intersection L is v = <1, 1, -2>. (b) The cartesian equation of the plane is -7x + 10y - 3z = -1

(a) To find a vector v parallel to the line of intersection L, we need to take the cross product of the normal vectors to the two given planes. The normal vectors are the coefficients of x, y, and z in the equations of the planes.

In this case, the equations of the planes are:

x + y - 2z = 1

4x + y + 3z = 4

The normal vectors to these planes are <1, 1, -2> and <4, 1, 3>, respectively. Since the line of intersection is parallel to both planes, a vector parallel to the line must be perpendicular to both normal vectors.

We can find such a vector by taking the cross product of the two normal vectors, which gives us: <1, 1, -2> × <4, 1, 3> = <-7, 10, -3>

Therefore, a vector v = <1, 1, -2>.

(b) To find the equation of the plane through the point (2, -1, 3) and perpendicular to L, we need to find a normal vector to the plane that is also parallel to L.

We can find such a vector by taking the cross product of the normal vectors to the two given planes. The normal vectors are <1, 1, -2> and <4, 1, 3>, so the cross product is: <1, 1, -2> × <4, 1, 3> = <-7, 10, -3>

This vector is parallel to L, so it can serve as the normal vector to the desired plane. The equation of the plane can be written in point-normal form as: -7(x - 2) + 10(y + 1) - 3(z - 3) = 0

Simplifying, we get:

-7x + 10y - 3z = -1

Therefore, the cartesian equation of the plane is -7x + 10y - 3z = -1, and it passes through the point (2, -1, 3) and is perpendicular to the line of intersection between the given planes.

The original price can be defined as the cost price of an item or a service. The decrease in the original price of a product or service is called the discount offered to the buyer. Generally, this discount is expressed as a percentage.

Original Sale Price means the price at which the current Owner purchased the Property (not including commissions, loan origination fees, appraisals fees, title insurance premiums and other similar transaction costs).

To calculate this, we need to find 6% of the original price and add it to the original price:

6% of 139.99 = 0.06 x 139.99 = 8.3994

Adding this to the original price gives:

139.99 + 8.3994 = 148.3894

Rounding to the nearest cent gives $148.39.

Distance time speed of different animals are:

Lion = 60 km/h  Sailfish = 130 km/h Peregrine Falcon  = 389 km/h Cheetah = 120 km/h  Springbok = 100 km/h Golden Eagle  = 320 km/h.

Here are the answers for each one:

1. Lion: The lion traveled a distance of 30 kilometers in a time of 30 minutes. To find the lion's speed, we can use the formula: speed = distance ÷ time. So, the lion's speed was 30 km ÷ 0.5 hours = 60 km/h.

2. Sailfish: The sailfish traveled a distance of 195 kilometers in a time of 1 hour and 30 minutes, which is the same as 1.5 hours. To find the sailfish's speed, we can again use the formula: speed = distance ÷ time. So, the sailfish's speed was 195 km ÷ 1.5 hours = 130 km/h.

3. Peregrine Falcon: The peregrine falcon traveled a distance of 778 kilometers in a time of 120 minutes, which is the same as 2 hours. To find the peregrine falcon's speed, we can once again use the formula: speed = distance ÷ time. So, the peregrine falcon's speed was 778 km ÷ 2 hours = 389 km/h.

4. Cheetah: The cheetah traveled a distance of 30 kilometers in a time of 15 minutes, which is the same as 0.25 hours. To find the cheetah's speed, we can use the formula: speed = distance ÷ time. So, the cheetah's speed was 30 km ÷ 0.25 hours = 120 km/h.

5. Springbok: The springbok traveled a distance of 10 kilometers in a time of 6 minutes, which is the same as 0.1 hours. To find the springbok's speed, we can use the formula: speed = distance ÷ time. So, the springbok's speed was 10 km ÷ 0.1 hours = 100 km/h.

6. Golden Eagle: The golden eagle traveled a distance of 240 kilometers in a time of 45 minutes, which is the same as 0.75 hours. To find the golden eagle's speed, we can use the formula: speed = distance ÷ time. So, the golden eagle's speed was 240 km ÷ 0.75 hours = 320 km/h.
