Step-by-step explanation:

Pythagorean theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

c^2 = a^2 + b^2

15^2 = a^2 + b^2

a^2 = 15^2 - 7^2 = 225 - 49 = 176

The equation y^(2)-x+10=0 has no symmetry.

Symmetry is when one part of an equation is the mirror image of another part. In this case, there is no symmetry because the equation cannot be mirrored on any axis.

To check for symmetry with respect to the y-axis, we can replace x with -x and see if the equation is still true. In this case, y^(2)-(-x)+10=0 is not the same as the original equation, so there is no symmetry with respect to the y-axis.

Similarly, to check for symmetry with respect to the x-axis, we can replace y with -y and see if the equation is still true. In this case, (-y)^(2)-x+10=0 is not the same as the original equation, so there is no symmetry with respect to the x-axis.

Finally, to check for symmetry with respect to the origin, we can replace x with -x and y with -y and see if the equation is still true. In this case, (-y)^(2)-(-x)+10=0 is not the same as the original equation, so there is no symmetry with respect to the origin.

Therefore, the equation y^(2)-x+10=0 has no symmetry.

Option D is correct, the total purchase price is $111.65.

percentage, a relative value indicating hundredth parts of any quantity.

Lets find the price of each item

Inflatable shark: $12.99

8 gallons of chlorine at $1.99 each: 8 x $1.99 = $15.92

2 gallons of algaecide at $7.99 each: 2 x $7.99 = $15.98

1 thermometer for $12.99: $12.99

2 sets of fins at $22.99 each: 2 x $22.99 = $45.98

Now add the costs of all the items:

$12.99 + $15.92 + $15.98 + $12.99 + $45.98 = $103.86

we multiply the total cost by the tax rate to find the sales tax.

$103.86 x 0.075 = $7.79

Finally, we add the sales tax to the total cost to get the final purchase price:

The expression of one hundred twenty rupees and five paise in rupees is equals to the rupees 120.05.

We have, 120 rupees and 5 paise and we will express as rupees using decimals.

We have been given 5 paise. As we see 120 rupees so it's remain as it but we have to change 5 paise in rupees. Using the conversation factor, as we know that 100 paise = rupee 1

=> 1 paisa = Rs. 1/100

so, here conversation factor is = 1/100

The required value is obtained by multiplying the observed values by conversion factor. Therefore,

5 paise = Rs. (5×1/100)

Answer:

962.084375 meters² or 306.25π

Step-by-step explanation:

A diameter is a line that goes straight through the center of the circle. Since it goes through the center, it creates 2 radii. This splits the diameter into 2 separate parts, and since the diameter is 25 meters, that means that the radius will be 25/2 = 17.5 meters.

The formula for the area of a circle is pi • r²

Since we know the radius (17.5), we can solve this expression:

pi • 17.5²

pi • 306.25

If we use 3.1415 for pi, we get962.084375 meters²

The standard form for the circle x² - 10x + y² + 14y - 7 = 0 is (x - 5)² + (y + 7)² = 81. The correct answer is D.

To find the standard form of the given circle, we must complete the square by rearranging the equation and adding constants to both sides of the equation to create perfect squares. Here are the steps:

1. Rearrange the equation so that the x and y terms are together:
x² - 10x + y² + 14y = 7

2. Complete the square for the x terms by adding (10/2)² = 25 to both sides of the equation:
x² - 10x + 25 + y² + 14y = 7 + 25

3. Complete the square for the y terms by adding (14/2)² = 49 to both sides of the equation:
x² - 10x + 25 + y² + 14y + 49 = 7 + 25 + 49

4. Simplify the equation by factoring the perfect squares:
(x² - 10x + 25) + (y² + 14y + 49) = 7 + 25 + 49

(x - 5)² + (y + 7)² = 81

Answer: m=2

Step-by-step explanation: First convert the equation to slope-intercept form; y=mx+b. This new equation would be 3y=6x-12. Because y must be singular, each side must be divided by 3, to isolate the variable y. After doing this, the equation is y=2x-4. In terms of y=mx+b, m is attached to x, making the slope of this equation 2.

Mrs Sheperd was going  7.5 miles per hour

Let us assume that d represents the distance covered by Mrs Shepard, 't' represents the time required and 's' represents the speed of her bike.

Here, d = 5.25 miles

t = 0.7 hours

We know that the formula of speed is speed = distance/time

Using this formula we calculate the speed (s) of Mrs Shepard's bike.

speed = distance/time

⇒ s = d/t

⇒ s = 5.25/0.7

⇒s = 7.5 miles per hour

Answer:

   ∠e = 32°

   ∠d = 69°

   ∠f = 79°

Step-by-step explanation:

       Angle e and 32° are vertical angles, so this means that ∠e = 32° because vertical angles are congruent.

       Next, a straight line is equal to 180°, and angle e is equal to 32°, so we can write the following equation to solve for angle f:

69° + e + f = 180° ➜ 69° + 32° + f = 180° ➜ 101° + f = 180° ➜ f = 79°

       Lastly, angle d and 69° are also vertical angles, so this means that ∠d = 69° because vertical angles are congruent.

Answer:

Step-by-step explanation:

Since tangent is negative and is equal to the ratio of opposite over adjacent, we can assume that the angle theta lies in either the third or the fourth quadrant, where the x and y coordinates have opposite signs.

In the third quadrant, sine is positive and cosine is negative. Therefore, we have:

tangent theta = opposite/adjacent = -1

sine theta = opposite/hypotenuse > 0

cosine theta = adjacent/hypotenuse < 0

Using the Pythagorean identity, we have:

sin² theta + cos² theta = 1

=> opposite²/hypotenuse² + adjacent²/hypotenuse² = 1

=> opposite² + adjacent² = hypotenuse²

Since we are given that 3π/2 < theta < 2π, we can place the triangle in the third quadrant with a reference angle of π/2. This means that the opposite side is equal to the absolute value of the adjacent side. Let's assume that the hypotenuse is equal to 1, then we have:

opposite/adjacent = -1

=> opposite = -adjacent

opposite² + adjacent² = hypotenuse²

=> adjacent² + (-adjacent)² = 1

=> 2adjacent² = 1

=> adjacent = ±1/√2

Since cosine is negative in the third quadrant, we have:

cosine theta = adjacent/hypotenuse = -1/√2

Finally, we can use the reciprocal identity to find secant:

secant theta = 1/cosine theta = -√2

Therefore, the answer is A. Negative StartRoot 2 EndRoot.

Now, we can multiply the two fractions as follows:
(13)/(15) * (10)/(7) = (13*10)/(15*7) = (130)/(105)

Next, we need to simplify the fraction by finding the greatest common factor (GCF) of the numerator and denominator.The GCF of 130 and 105 is 5. So, we can divide both the numerator and denominator by 5 to get the simplest form of the fraction:

The concept of area is used in many areas of mathematics and in a wide range of real-world applications, including architecture, engineering, physics, and geography. The ability to calculate the area of a shape is an important skill in many fields and is a fundamental concept in geometry.

Here,

To solve this problem, we need to find the number of packages of paper that can fit on the warehouse shelf by dividing the total shelf area by the area of each package.

First, we need to convert the height of the shelf from feet and inches to inches:

1 foot = 12 inches

1' 5" = 1 * 12 + 5 = 17 inches

Next, we need to convert the length of the shelf from yards to inches:

1 yard = 36 inches

2 yards = 2 * 36 = 72 inches

Now we can find the area of the warehouse shelf:

Area = length * height

Area = 72 inches * 17 inches

Area = 1224 square inches

The area of each package of paper is:

Area = height * width

Area = 2 inches * 1.5 inches

Area = 3 square inches

According to the Pythagorean Theorem, the square of the length of the hypotenuse in a right triangle equals the total of the squares of the lengths of the other two sides. The hypotenuse is the side that faces the right angle. In mathematics, it can be expressed as:

c² = a² + b²

where the lengths of the other two sides (the legs) of the right - angled triangle are a and b, and c is the length of the hypotenuse. Pythagoras, an ancient Greek mathematician, is attributed with discovering and proving this theorem, so it bears his name. Geometry, algebra, and other fields of mathematics and science all make extensive use of the Pythagorean Theorem.

The Pythagorean formula can be used to determine side C.

C² = A² + B²
