Answer:

Step-by-step explanation:

The expression in standard form that represents the area of the square with side length s is given by:

A = s^2

However, if you want to substitute the value of s with the expression 5y+3, then the area expression becomes:

A = (5y+3)^2

Expanding the expression, we get:

A = 25y^2 + 30y + 9

Therefore, the expression in standard form that represents the area of the square with side length 5y+3 is 25y^2 + 30y + 9.

Answer:

[tex]16-(6.25+2*2.25)[/tex]

Step-by-step explanation:

To find the amount of money she has left, you want to subtract the price of the ticket and the price of the two snacks from the amount of money she starts with.

So we want to subtract 6.25 once and subtract 2.25 twice (because she bought two snacks) from 16

16-6.25-2*2.25

Or you can also do this by adding up the monetary value of the ticket and the snacks and subtract that from the initial amount of money that Parvati has

16-(6.25+2*2.25)

(I am assuming that the "2.2.25" is supposed to say [tex]2*2.25[/tex])

Answer:

f(x) = - [tex]\frac{1}{2}[/tex] x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 0 ) , x- intercept and (x₂. y₂ ) = (0, - 4) , y- intercept

m = [tex]\frac{-4-0}{0-2}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

to find c substitute (- 4, 7 ) into the partial equation

7 = - [tex]\frac{1}{2}[/tex] (- 4) + c = 2 + c ( subtract 2 from both sides )

5 = c

y = f(x) = - [tex]\frac{1}{2}[/tex] x + 5 ← equation of function

Answer:

Saanvi recorded the number of math problems she did for homework each night for 10 days.

Step-by-step explanation:

The perimeter of the circle formed by bending the rectangular wire will be equal to the length of the wire.

Perimeter of the circle = Length of the wire

2πr = 2(l+b) where r is the radius of the circle, l is the length of the wire, and b is the breadth of the wire.

Substituting the given values, we get:

2 x 3.14 x r = 2(32 + 12)

6.28r = 88

r = 14 cm

Therefore, the radius of the circle is 14 cm.

Answer:

14.01 cm

Step-by-step explanation:

The length of the wire is equal to the perimeter of the rectangle. So, the length of the wire is:

When this wire is bent into a circle, its length becomes equal to the circumference of the circle. The formula for the circumference of a circle is:

(let r = radius)

So, we can write:

Solving for r, we get:

So, the exact value of the radius of the circle formed by bending this rectangular wire is 14.01 cm.

The relation is not a function, but rather a circle with center at the origin and radius 2.

Given the relation in the question;

x² + y² = 4.

First, lets solve for y.

x² + y² = 4

Subtract x² from both sides

x² - x² + y² = 4 - x²

y² =  4 - x²

Take the squre root of both sides

y = ±√( 4 - x² )

This shows that for a given value of x, there are two possible values of y. One positive and one negative, that satisfy the equation.

Therefore, the relation is not a function.

We know that Ryan can install 144 square feet of flooring in 3 hours.

So, if we take 144 square feet, and divide by 3 hours, 144 / 3, we end up with 48, meaning Ryan can install 48 square feet of flooring every hour.

Then, simply multiply 48 by 18, 48 x 18, and you end up with 864.

Meaning, in 18 hours, Ryan can install 864 square feet of flooring.

Answer: 864 square feet.

Option D. The approximate surface area of the drum is 2744 1/7 in². The surface area of a cylinder can be calculated using the formula:

A = 2πr² + 2πrh

where r is the radius of the base, h is the height of the cylinder, and π is the mathematical constant pi, which we can approximate as 3.14.

Plugging in the given values, we get:

A = 2 x 3.14 x 13² + 2 x 3.14 x 13 x 20.5

= 1060.04 + 1684.06

≈ 2744.1

Rounding this to the nearest 1/7, we get:

2744 1/7 in²

Pythagoras - Has a theorem named after him

Thales - Contributed to the five basic theorems of geometry

Pythagoras was a Greek philosopher, mathematician, and founder of the Pythagorean school of philosophy. He lived in the 6th century BCE on the Greek island of Samos and is known for his contributions to mathematics, geometry, music, and philosophy.

Pythagoras is most famous for the theorem that bears his name, the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem is fundamental to the study of geometry and has applications in many fields, from architecture to physics.

The function f(x) = 81 − x2 is increasing on the interval (−∞, 9) and decreasing on the interval (9, ∞).

Parabola is a type of curve which is defined by the quadratic equation. It has a distinct "U" shape, with the vertex of the curve being the highest or lowest point.

The point x = 9 is the vertex of the parabola, which marks the point at which the function changes from increasing to decreasing.

Since the function is a parabola, it is also a polynomial of degree 2, and it is always decreasing for points greater than the vertex, and increasing for points less than the vertex.

This means that the function is increasing on the interval (−∞, 9) and decreasing on the interval (9, ∞).

We can cut 6 pieces of rope measuring 5/8 of a foot from a rope of 4 3/8 feet, with some rope left over.

Area is a measurement of the size of a surface or a region in a two-dimensional space. It is expressed in square units, such as square inches (in²), square meters (m²), or square feet (ft²). To find the area of a shape, you need to multiply its length by its width, or use an appropriate formula depending on the shape. For example, the formula for the area of a rectangle is A = l × w, where A is the area, l is the length, and w is the width.

To find the number of pieces of rope measuring 5/8 of a foot that can be cut from a rope of 4 3/8 feet, we need to divide the length of the rope by the length of each piece of rope:

4 3/8 feet = 4 + 3/8 feet = 4 feet + (3/8) x 12 inches = 4 feet + 3 inches = 51 inches

Each piece of rope measures 5/8 of a foot, which is equivalent to 5/8 x 12 inches = 7.5 inches.

Now we can divide the length of the rope (in inches) by the length of each piece of rope (in inches) to find the number of pieces:

51 inches ÷ 7.5 inches ≈ 6.8

Therefore, we can cut 6 pieces of rope measuring 5/8 of a foot from a rope of 4 3/8 feet, with some rope left over.

According to the solving $310 money you have in savings after 26 weeks, we can use either the recursive or explicit formula:

The explicit equations for L-functions are Riemann's relations between sums over an L-function's complex number zeroes and sums over prime powers for the Riemann zeta function.

a) Recursive formula:

Let S(n) be the amount of money in savings after n weeks. Then:

S(0) = 50 (initial amount)

S(n) = S(n-1) + 10 (deposit of $10 per week)

b) Explicit formula:

The explicit formula for this sequence is:

S(n) = 50 + 10n, where n is the number of weeks.

c) To find how much money you have in savings after 26 weeks, we can use either the recursive or explicit formula:

Using the recursive formula:

S(0) = 50 (initial amount)

S(1) = S(0) + 10 = 50 + 10 = 60

S(2) = S(1) + 10 = 60 + 10 = 70

S(3) = S(2) + 10 = 70 + 10 = 80

and so on, until:

S(26) = S(25) + 10 = 310

Therefore, after 26 weeks, you have $310 in savings.

Using the explicit formula:

S(26) = 50 + 10(26) = 50 + 260 = 310

after 26 weeks, you have $310 in savings.

The solution will be b=4, the number b such that the average rate of change of f on the interval [2, b] is - 1/18 if the provided assertion is correct.

For instance, a range between 0 and 10 would include all of the integers between them, not just 1, 2, 3, 4, 5, 6, 7, 8, and 9. These would additionally incorporate fractional numbers like 1.3 and components like 1/10. We therefore have the job. We must determine b to the extent that the interval [2, b]'s average percentage of change or slope is -1/8. Discover f first(2).

f(2) = 1/(2) = 1/2

So, we have the point (2, 1/2)

At point b, f(b) = 1/b.

Let's plug this into the slope formula

We simply have to figure out b now. Let's start by multiplying the divisor and fraction by b.

Now, cross multiply.

Solve for b. Use the factors -4 and -2 to multiply.

Thus, b=4 or b=2.

However, b=2 cannot be the answer because the range [2,2] has no significance. Thus, b=4.
