Mrs. Battle is designing a brick walkway to install in her front yard. How many square feet of bricks will be needed for the walkway?

The Geometric Mean of a Leg Theorem, or the Geometric Mean Theorem, is related to right triangles and their altitude.

The Geometric Mean of a Leg Theorem states that " In a right triangle, the length of the altitude to the hypotenuse is the geometric mean of the lengths of the two segments of the hypotenuse created by the altitude."

It can be proven by assuming you have a right  triangle ABC, where angle BAC is the right angle, BC is the hypotenuse, AD is the altitude, and BD and DC are the two segments of the hypotenuse created by the altitude.

This shows the proof of the Geometric Mean of a Leg Theorem.

Slope = ∆y/∆x

slope = ( -5_1 ) / ( 3_-3 )

slope = -6 / 6

slope = -1

Evaluate 9 to the power of -1/2

=> 0.05

The equivalent expression of ''9 to the power of -1/2'' would be 1/3.

Used the concept of the square root of a number that states that,

The square root of a number is the number that, when multiplied by itself, gives the original number.

Given that,

The expression is 9 to the power of -1/2.

Now, it can be written as,

9 to the power of -1/2

\(= 9^{- 1/2}\)

\(= \dfrac{1}{9^{1/2} }\)

\(= \dfrac{1}{(3^2)^{1/2} }\)

x = 147 / 0.5446 ≈ 270.2 ft

To find the length of the guy wire for a radio transmission tower, trigonometry concepts are applied. Given a tower height of 160 feet, with the wire attached 13 feet from the top and making an angle of 29° with the ground, we can solve for the length of the guy wire, represented by x.

Using the Pythagorean theorem and considering the right triangle formed by the tower height, the wire attachment point, and the ground, we can set up the equation:

x = √((160 - 13)² + x²)

Next, we apply the tangent function to the given angle:

tan(29°) = (160 - 13) / x

Simplifying, we have:

0.5446 = 147 / x

To solve for x, we rearrange the equation:

x = 147 / 0.5446 ≈ 270.2 ft

Rounding to the nearest tenth of a foot, the length of the guy wire required is approximately 270.2 feet. This wire is attached 13 feet from the top of the tower and makes a 29° angle with the ground.

The possible values of ∠K are approximately 19.0° and 341.0° to the nearest tenth of a degree.

To find the measure of angle K, we can use the law of cosines

cos(K) = (k² + m² - 2km cos(M)) / (2km)

Substituting the given values:

cos(K) = (94² + 79² - 29479cos(161°)) / (294*79)

cos(K) ≈ 0.4824

Taking the inverse cosine of both sides, we get

K ≈ 60.3° or K ≈ 299.7°

Since the triangle is a plane figure, the sum of its angles must be 180°. Since we know that ∠M = 161°, we can determine the possible values of ∠K by subtracting ∠M from 180°

∠K = 180° - ∠M = 180° - 161° = 19°

or

∠K = 180° + ∠M = 180° + 161° = 341°

The repeating decimal 0.8 as a geometric series 0.8 = 8/10 + (8/10)^2 + (8/10)^3 + ...

To express the repeating decimal 0.8 as a geometric series, we can start by observing the repeating pattern. In this case, the digit 8 repeats indefinitely. We can write 0.8 as follows:

0.8 = 0.8888...

To convert this into a geometric series, we need to identify a common ratio that will generate each subsequent term. In this case, the common ratio can be obtained by dividing the repeating digit by 10, which represents the shifting of the decimal point to the right. Thus, the common ratio is 8/10, which simplifies to 4/5.

Now we can express the repeating decimal 0.8 as a geometric series using the formula for an infinite geometric series:

0.8 = 8/10 + (8/10)^2 + (8/10)^3 + ...

In general, the nth term of the series is given by (8/10)^n. Since the repeating decimal has an infinite number of terms, we have successfully represented 0.8 as a geometric series.

Option C is correct.

The function can be defined as an expression that defines a relationship between one independent variable with another dependent variable.

The given function is \(f(x) = x^2-6x+1\).

The function needed more unit tiles to add so that it becomes a complete square.

The given function is an order 2 function, the side of the square will be order 1. Let's consider an order 1 function ax+b to be the side of the square. Also, consider that t number of tiles added to the order 2 function so that it can become the perfect square.

\(f(x) + t = (ax+b)^2\)

\(x^2 -6x + 1 + t = a^2x^2 + 2abx + b^2\)

By comparing the integers of both sides of orders, we get

\(a^2=1, \;2ab = -6, \; b^2 = 1+t\)

Putting the value of a to get the value of b,

Step-by-step explanation:

A tip of 18% was given to the restaurant after the meal and tax to the nearest percentage.

Cost of the food = $25.30

Tax on the food cost = 8%

Tax amount

= 8% of 25.30

= 0.08  × 25.30

= 2.204

Total cost of food before tip = 25.30 + 2.204 = $27.504

Tip given = 32.24 - 27.504 = 5.036

Tip percentage

= 5.036 / 27.504 × 100%

= 18.31%

≈ 18%

Hence a tip of 18% was given to the restaurant after the meal and tax to the nearest percentage.

If a woman pays $2.78 for some bananas and eggs. If each banana costs $0.69 and each egg costs $0.35, then she bought 4 bananas and 6 eggs.

Let's assume the woman bought x bananas and y eggs.

According to the problem, each banana costs $0.69 and each egg costs $0.35.

So the cost of x bananas would be 0.69x and the cost of y eggs would be 0.35y.

The total cost of the bananas and eggs is given as $2.78. So we can write the equation:

0.69x + 0.35y = 2.78

Now we need to solve for x and y.

We can start by multiplying the entire equation by 100 to get rid of the decimals:

69x + 35y = 278

We can also simplify the equation by dividing both sides by 1 (which doesn't change the equation):

69x/1 + 35y/1 = 278/1

Now we can use a system of equations to solve for x and y.

Let's solve for y in terms of x by isolating y on one side of the equation:

35y = 278 - 69x

y = (278 - 69x)/35

Now we can substitute this expression for y into the original equation:

0.69x + 0.35((278 - 69x)/35) = 2.78

Simplifying this equation, we get:

0.69x + 8 - 2x = 2.78

Solving for x, we get:

0.69x - 2x = 2.78 - 8

-1.31x = -5.22

x = 4

So the woman bought 4 bananas.

Now we can substitute this value for x into the expression we derived for y:

y = (278 - 69(4))/35

y = 6

So the woman bought 6 eggs.

Therefore, the woman bought 4 bananas and 6 eggs.
