Its surface area serves as a fair guide of its total size. The environment is considered when calculating the right triangle squared. Everything's overall size is determined by its surface area. The volume of water inside a cuboid is equal to the sum of the contents from each of its twelve vertical sides. To determine the box's dimensions, use the formula below: 2lh, 2lw, and 2hW symbolise the area (SA). The full surface area of the flexible shape serves as the area's representation.

Here,

The area of the door is:

Area = height x width

Area = 7 ft x 4 ft

Area = 28 sq ft

The cost per square foot is $5.09, so the total cost of the new door would be:

Cost = Area x cost per square foot

Cost = 28 sq ft x $5.09/sq ft

Cost = $142.52

Therefore, a new bedroom door would cost $142.52 in total.

Period, which is a measure of how long an oscillation lasts, is constant. With L being the pendulum's length and g being the acceleration brought on by gravity, the formula for calculating a pendulum's period is T = 2π √L/g,

A simple pendulum is a machine whose point mass is suspended from a fixed support by a light, inextensible string. When a pendulum is displaced sideways from its resting position due to gravity, the equilibrium position is subjected to a restoring force that will accelerate it back toward the equilibrium position.

Only the length of the string affects a pendulum's period; the mass of the ball has no bearing. When two pendula are the same length but have different masses, their periods will be the same. The pendulum with the longer string will have a longer period if there are two of them, but their periods will differ.

Step-by-step explanation:

REMEMBER: for a right triangle  sin (30) = opposite LEG/ hypotenuse

  so sin 30 =  4 / hypotenuse         now, with a calculator sin 30 = 1/2

            1/2   = 4 / hypotenuse      so hypotenuse = 8

Now it is a right triangle so Pythagorean theorem applies

  hyp ^2 = 4 ^2   +   BM^2

   8^2 = 4^2 + BM^2

      48 = BM^2     so  BM = sqrt (48 ) = 4 sqrt 3

Finally, all of the internal angles of ANY triangle sum to 180 °

   so angle x = 180 - 90 - 30 = 60°

The vertex form of a quadratic function is given by:

f(x) = a(x - h)^2 + k

where (h, k) is the vertex of the parabola.

Since the graph of f(x) = x^2 was translated 6 units to the left to create the graph of g, the vertex of g is at the point (h - 6, k).

The vertex of f(x) = x^2 is at (0, 0), so the vertex of g is at (-6, 0).

Since the vertex is at (-6, 0), the equation of g in vertex form is:

g(x) = a(x + 6)^2 + 0

We can find the value of "a" by using another point on the parabola. For example, if we know that g(-3) = 9, then we can substitute these values into the equation and solve for "a":

9 = a(-3 + 6)^2

9 = 9a

a = 1

So the equation of g in vertex form is:

g(x) = (x + 6)^2

The Correct answer will be B. f(x) is shifted π/4 units to the left.

The general equation for a sine and cosine curve is y = A sin ⁡ ( x − h ) + k and y = A cos ⁡ ( x − h ) + k , respectively. Similar to other function transformations, is the horizontal shift (also called a phase shift), and is the vertical shift.Changes to the amplitude, period, and midline are called transformations of the basic sine and cosine graphs. Changing the midline shifts the graph vertically. The graph is stretched or compressed vertically depending on the amplitude. The graph is stretched or compressed horizontally depending on the era.

AS per the measurement, the value of 5'2 in meters is 1.5748 meters.

One common unit of measurement is the foot, which is often used to measure height. However, in some scientific fields, the meter is the preferred unit of measurement.

To convert 5'2 into meters, we first need to understand the relationship between feet and meters. One foot is equal to 0.3048 meters, which means that we can convert 5 feet to meters by multiplying 5 by 0.3048. This gives us 1.524 meters.

But what about the additional 2 inches? We can convert inches to meters by dividing the number of inches by 39.37 (the number of inches in a meter). In this case, 2 inches divided by 39.37 equals 0.0508 meters.

To get the total measurement in meters, we simply add the two values: 1.524 + 0.0508 = 1.5748 meters.

Therefore, 5'2 is equivalent to 1.5748 meters.

ABCD is a kite, therefore, ΔAEC is a right Δ

Step-by-step explanation:

Look at ΔABD and ΔACD, they both have the same side AD, AB = AC while BD = CD. Therefore ΔABD and ΔACD are congruent or basically the same triangle.

Both ΔABD and ΔACD will form a quadrilateral, which can be called a kite.

Definition: A kite is a quadrilateral with two pairs of adjacent sides, congruent.

Therefore, a kite has perpendicular diagonals, where one bisects the other.

So AD is perpendicular to BC

so the angles AEC, ABD, DEC, DEB are all right angles.

It should be noted that point C is located at (2.6, 1.8).

The length of horizontal side = (xB − xA) = 4 units

length of vertical side = (yB − yA) = 2 units

To find the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3, first convert the ratio between the parts into the fraction of the sum that the first part is equal to:    a/a+b= 2/2+3= 2/5

Multiply the length of the horizontal side by the fraction, and then add the result to the x-coordinate of point A:  Xc= Xa  + (a/a+b) (Xb - Xa) = 1+ (2/5 x 4) = 2.6

Multiply the length of the vertical side by the fraction, and then add the result to the y-coordinate of point A:  Yc= Ya  + (a/a+b) (Yb - Ya) = 1+ (2/5 x 2) = 1.8

It follows that point C is located at (2.6, 1.8).

a) The simple interest earned is $810. b) The annual interest rate paid by the credit union is 5.4%. c) It will take about 12.81 years for Mr. Adams' investment to be doubled at the same rate of interest.

a) To find the simple interest earned, we can use the formula:

Simple interest = Principal x Interest rate x Time

Where the principal is $5,000, the time is 3 years, and the total amount received at the end of 3 years is $5,810. We can rearrange the formula to solve for the interest rate:

Simple interest = $5,810 - $5,000 = $810

Interest rate = Simple interest / (Principal x Time)

Interest rate = $810 / ($5,000 x 3)

Interest rate = 0.054 or 5.4%

b) The annual interest rate paid by the credit union is 5.4%.

c) To find the length of time it will take for Mr. Adams' investment to be doubled at the same rate of interest, we can use the formula:

Doubling time = ln(2) / ln(1 + r)

Where r is the interest rate as a decimal. Plugging in the values:

Doubling time = ln(2) / ln(1 + 0.054)

Doubling time ≈ 12.81 years

Therefore, it will take about 12.81 years for Mr. Adams' investment to be doubled at the same rate of interest.

Therefore, the value of the car after three years is approximately $9,484.

Percent is a term used to represent a fraction of 100. It is denoted by the symbol "%". Percentages are commonly used to express proportions, ratios or fractions in terms of parts per hundred. The word "percent" comes from the Latin phrase "per centum," which means "by the hundred." Percentages are commonly used in everyday life, such as in calculating taxes, discounts, interest rates, and in comparing statistics, among others.

Here,

The exponential decay model for the value of the car after ⁿ years can be written as:

v = 22500 * (0.75)ⁿ

where 22500 is the initial value of the car, and (0.75)ⁿ represents the value after ⁿ years with a 25% annual decrease.

To find the value of the car after three years, we can substitute n = 3 into the equation:

v = 22500 * (0.75)³

The value of the equation f(x)=-3x+5 at f(-2) is 11.

An equal sign ("=") links two expressions together to form an equation. The two expressions on either side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation. The right side of an equation is typically assumed to be zero. As we can balance this by deducting the expression on the right from the expressions on both sides, this won't reduce the generality.

The given equation is f(x)=-3x+5.

Substitute the value of x = -2 in the equation to find f(-2).

f(x)=-3x+5

f(-2) = -3(-2) + 5

f(-2) = 6 + 5

As per the arithmetic sequence, the farmer have 21 cows in his first year on the farm

An arithmetic sequence is a sequence of numbers in which each successive number is obtained by adding a fixed number to the previous number.

To determine the common difference, we can take the difference between any two consecutive terms in the sequence.

The difference between the 2nd and 5th years is 9 cows

=> (39 - 30 = 9).

Now that we know the common difference is 9, we can use it to find the first term of the sequence. To do this, we can take the second term (30 cows) and subtract the common difference from it.

This would give us the first term of the sequence, which is 21 cows.

Therefore, the farmer had 21 cows in his first year on the farm.

the parabola has an equation of y = (-1/8)x² + (1/2)x - 1/2, its vertex is at (2, 0), and it opens to the left with a focus at (0, -2) and a directrix at x=2.

Since the directrix of the parabola is a vertical line x=2, the axis of the parabola is horizontal, and its vertex is the point of intersection between the axis and the directrix, which is (2, 0). The focus is located at (0, -2), which is two units below the vertex, so the distance between the focus and the vertex is |p| = 2, where p is the distance between the vertex and the directrix. Since the directrix is to the right of the vertex, the parabola opens to the left. Therefore, its equation can be written in the form:

(x - h)² = -4p(y - k)

where (h, k) is the vertex. Plugging in the values we have, we get:

(x - 2)² = -8(y - 0)

Simplifying, we get:

x² - 4x + 4 = -8y or

y = (-1/8)x² + (1/2)x - 1/2

Therefore, the parabola has an equation of y = (-1/8)x² + (1/2)x - 1/2, its vertex is at (2, 0), and it opens to the left with a focus at (0, -2) and a directrix at x=2.
