In its simplest radical form, the area of the right triangle is 8sqrt(3) square feet.

How is area determined?

The length of the other leg of the right triangle can be determined using the Pythagorean theorem:

[tex]a^2 + b^2 = c^2[/tex]

where the hypotenuse is c and the triangle's legs are a and b.

We are aware that the hypotenuse c is 8 feet long and that leg an is 4 feet long. Let's work out the answer for the opposite leg's length, b:

[tex]b^2 = c^2 - a^2\sb^2 = 8^2 - 4^2\sb^2 = 64 - 16\sb[/tex]

[tex]sqrt(48) = 4sqrt(3) foot where 2 = 48 b[/tex]

Given that we know the lengths of both legs, we can use the following formula to get the triangle's area:

[tex](1/2) * Base * Height = Area[/tex]

We may use the 4 ft leg as the base and the 4sqrt(3) ft leg as the height since one leg is 4 ft and the other is 4sqrt(3) ft:

Area: (1/2) * 4 feet * 4 square feet (3)

= 8sqrt(3) square feet

The streetlight is approximately 16.41 feet tall, and the length of its shadow is approximately 27.35 feet.

What is the proportion?

A proportion is a statement that two ratios are equal. In other words, a proportion is an equation that shows that two fractions or two ratios are equivalent. A proportion can be written in the form of:

a/b = c/d

We can use the properties of similar triangles to solve this problem. Let's call the height of the streetlight h, and the length of the shadow cast by the streetlight x. We can set up the following proportion:

(height of person) / (length of person's shadow) = (height of streetlight) / (length of streetlight's shadow)

or

6 / 10 = h / x

Simplifying this proportion, we get:

x = (10h) / 6

We also know that the person is standing 18 feet from the streetlight, and that the length of the person's shadow is 10 feet. Using the Pythagorean theorem, we can set up the following equation:

6^2 + 10^2 = (18 + x)^2

Simplifying and substituting x, we get:

36 + 100 = (18 + (10h/6))^2

136 = (18 + (10h/6))^2

Taking the square root of both sides, we get:

√136 = 18 + (10h/6)

Simplifying, we get:

√136 - 18 = (10h/6)

Multiplying both sides by 6, we get:

6(√136 - 18) = 10h

Simplifying, we get:

h ≈ 16.41 feet

Now, we can substitute this value of h into the expression for x that we derived earlier:

x = (10h) / 6 ≈ 27.35 feet

Therefore, the streetlight is approximately 16.41 feet tall, and the length of its shadow is approximately 27.35 feet.

The solutions to the quadratic equation x^(2)=2x+8 are x=4 and x=-2.

To solve the quadratic equation x^(2)=2x+8 by factoring, we need to rearrange the equation to make it equal to zero and then factor the trinomial.

Step 1: Rearrange the equation to make it equal to zero.
x^(2)-2x-8=0

Step 2: Factor the trinomial using the "AC Method."

The "AC Method" involves finding two numbers that multiply to the product of the coefficient of the x^(2) term (a) and the constant term (c), and add to the coefficient of the x term (b).

In this case, a=1, b=-2, and c=-8.
The product of a and c is (1)(-8)=-8.
The two numbers that multiply to -8 and add to -2 are -4 and 2.

Step 3: Rewrite the equation using the two numbers found in Step 2.
x^(2)-4x+2x-8=0

Step 4: Factor by grouping.
(x^(2)-4x)+(2x-8)=0
x(x-4)+2(x-4)=0

Step 5: Factor out the common factor (x-4).
(x-4)(x+2)=0

Step 6: Set each factor equal to zero and solve for x.
x-4=0  or  x+2=0
x=4  or  x=-2

Therefore, the solutions to the quadratic equation x^(2)=2x+8 are x=4 and x=-2.

Area of the triangle ≈ 7.5 (to the nearest tenth).

To find the area of the triangle given its side lengths, we will use Heron's formula:

s =(a + b + c)/2

A = sqrt(s(s-a)(s-b)(s-c))

where s is the semiperimeter of the triangle, and A is the area of the triangle.

For the given triangle, we have:

a = 3

b = 5

c = 6

The semiperimeter s can be calculated as:

s = (a + b + c) / 2 = (3 + 5 + 6) / 2 = 7

Using this value of s, we can apply Heron's formula to find the area A:

A = √(s(s-a)(s-b)(s-c))

= √(7(7-3)(7-5)(7-6))

For two vectors to be orthogonal, their dot product should be zero.

(a) The dot product of u and v is k+21k=22k. For u and v to be orthogonal, 22k=0, which means k=0.

(b) The dot product of u and v is -2k^2+5k^2+k^2=4k^2. For u and v to be orthogonal, 4k^2=0, which means k=0.

Therefore, in both cases, the vectors are orthogonal when k=0.

Let AB and AC be vectors joining the points A(0,-1), B(1,-2), and C(4,1), respectively. Then,

AB = (1-0, -2-(-1)) = (1,-1)

The coordinates of point L are (s/2, s√3/2). If we know the value of s, we can determine the specific coordinates of point L.

To determine the coordinates of point L in an equilateral triangle with vertices J and K, we first need to know the location of J and K.

Since the triangle is equilateral, the distance from J to K is the same as the distance from J to L or from K to L. Let's assume that the side length of the equilateral triangle is s. Then, the distance from J to K is also s. We can assume that J is located at the origin (0,0), and K is located at (s,0).

To find the coordinates of point L, we can use some trigonometry. Let's draw a line from point K to point L, and let the angle between this line and the x-axis be θ. Since the triangle is equilateral, this angle is 60 degrees.

The x-coordinate of point L is then given by s cos θ. Since cos 60 = 1/2, the x-coordinate of point L is s/2.

The y-coordinate of point L is given by s sin θ. Since sin 60 = √3/2, the y-coordinate of point L is s√3/2.

The ordered pair that is NOT a solution of y > 3x + 4 is (-2, 1). Hence, the answer is (E) (-2, 1).

A relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.

The given inequality is y > 3x + 4. To check which ordered pair is not a solution of this inequality, we need to substitute the values of x and y from each ordered pair into the inequality and check whether the inequality holds or not.

Checking the ordered pairs one by one, we have:

(2, 12): y = 12 and x = 2, so 12 > 3(2) + 4 is true. Therefore, (2, 12) is a solution of the inequality.

(0, 5): y = 5 and x = 0, so 5 > 3(0) + 4 is true. Therefore, (0, 5) is a solution of the inequality.

(-2, 1): y = 1 and x = -2, so 1 > 3(-2) + 4 is false. Therefore, (-2, 1) is not a solution of the inequality.

(1, 7): y = 7 and x = 1, so 7 > 3(1) + 4 is true. Therefore, (1, 7) is a solution of the inequality.

These are the x-coordinates of the points where the graph intersects the x-axis. We can use these points to sketch the curve of the function.

An equation is a mathematical statement that indicates the equality of two expressions. It consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is equivalent to the expression on the right side. Equations can have one or more variables, which are usually represented by letters such as x, y, or z. The goal in solving an equation is to determine the value(s) of the variable(s) that make the equation true. This involves manipulating the expressions on both sides of the equal sign using algebraic operations such as addition, subtraction, multiplication, and division, to isolate the variable on one side of the equation. Equations are used in many areas of mathematics and science to represent relationships between variables and to solve problems. They are also used in various fields such as engineering, physics, and economics to model real-world situations and make predictions based on mathematical analysis.

The function ƒ(x) = −x³ + 4x² − 2 is a cubic function, which means that it is a polynomial of degree 3. The general form of a cubic function is:

ƒ(x) = ax³ + bx² + cx + d

where a, b, c, and d are constants. In the given function, we have:

a = -1

b = 4

c = 0

d = -2

Therefore, we can rewrite the function as:

ƒ(x) = -x³ + 4x² - 2

This function can be graphed to show the shape of the curve it creates. The graph of a cubic function is a curve that can either be concave up or concave down, depending on the sign of the leading coefficient. In this case, the leading coefficient is negative, so the graph will be concave down. The function has a y-intercept of -2, which means that it intersects the y-axis at the point (0, -2). To find the x-intercepts, we can set ƒ(x) equal to zero and solve for x:

ƒ(x) = -x³ + 4x² - 2 = 0

We can use factoring or the quadratic formula to solve for x, but in this case, the equation can be simplified by factoring out a common factor of x²:

The value of v is 8.83.

A rational equation is an equation that includes one or more fractions with polynomials. It can be solved by cancelling common factors between the numerator and the denominator, and then solving the resulting equation. It is important to note that when cancelling common factors, one must always check that the original equation is still satisfied.

To solve this rational equation that simplifies to linear, you need to solve for v. To do this, first multiply both sides by the denominator:

6(v-8) = 5

Then add 8 to both sides to get rid of the variable in the denominator:

6v - 48 = 5

Finally, add 48 to both sides to isolate the variable v:

6v = 53

Finally, divide both sides by 6 to solve for v:
