Among the three students the weight of Darren at birth was the lowest with 8.25 pounds.

What is weight?

Weight gauges how much gravity is pulling on a body.

The weight formula is provided by -

w = mg

Since weight is a force, it has the same SI unit as a force, which is Newton (N).

The students from lightest to heaviest weight at birth are -

Darren (8.25 pounds) < Joel (8.34 pounds) < Rebecca (8.388 pounds)

This is because 8.25 is less than 8.34, and 8.34 is less than 8.388. In other words, Darren weighed the least at birth, followed by Joel, and then Rebecca weighed the most.

It's important to note that the differences in weight between the students are relatively small, and all three weights are within a narrow range.

However, when comparing weights, even small differences can be significant.

Therefore, the lowest weight was of Darren (8.25 pounds).

To solve 5(98) =___(100-2) using the distributive property, we can distribute the 5 to both the 100 and the -2:

5(98) = 5(100 - 2)

Now, we can use the distributive property to simplify the right side:

5(98) = 5(100) - 5(2)

Multiplying, we get:

490 = 500 - 10

Simplifying further, we get:

490 = 490

Therefore, the equation is true, and we have verified the distributive property.

What is right angle triangle?

The term "right-angled triangle" refers to any triangle with an internal angle that is either a right angle or 90 degrees in value. The right triangle or the 90-degree triangle are other names for this triangle because of this. Right triangles have "opposite" and "adjacent" sides, which refer to the sides that are across from and next to respective angles, respectively. When a right triangle is formed, the hypotenuse is its longest side.

We can consider the flagpole, the ground, and the rope as forming a right triangle. The angle between the flagpole and the rope is 90 degrees, and the angle between the rope and the ground is 35 degrees. Therefore, the angle between the flagpole and the ground is 90 - 35 = 55 degrees.

Let's call the length of the rope "r". We can use the trigonometric function tangent to find r:

tan(35°) = opposite/adjacent = r/20

Multiplying both sides by 20, we get:

r = 20 tan(35°)

Using a calculator, we get:

r ≈ 11.9 feet

Therefore, the length of the rope is approximately 11.9 feet.

Rewriting each explicit formula in function form given below:

[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]

[tex]f(n) = 4 * (1/3)^(^n^-^1^)[/tex]

To convert an explicit formula into a function form, one must denote the variable 'n' as its respective input and represent the formula with that of a function.

Listed below are the steps required:

Original formulas:

[tex]g n = -3.(1_2)n- 1g[/tex]

[tex]n = 4.(1_3)n-1[/tex]

In order to transform the original expression to function format, follow these instructions for each individual formula:

- Step 1: Establish both the name of the function and the input parameter it accepts, denoted respectively by 'g', or 'n'.

- Step 2: Alter the specified representation; replace "g n" with "g(n)".

- Step 3: Substitute the hyphen sign '_' with a division symbol '/'.

Subsequently, applying this method specifically on equation g n = -3 * (1_2)n - 1g generates:

[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]

Thus, the rewritten version in function format is displayed as priorly referred:

[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]

To implement the same procedure on another given formula, where it states n = 4 * (1_3)n - 1:

- Step 1: Uncover the variables' identity with regards to the name of the function and the current parameters utilized, therefore establishing a new function label 'f' while preserving the relative input, just like previously conducted during the initial steps.  

- Step 2: Adapt your notation appropriately utilizing the newly established variables mentioned in Step 1.

- Step 3: Substitute the underscore designation '*' present within the term with a forward slash '/'.

As a result, following the process will create the convenient formulation of the certain algebraic formula as f(n) = [tex]4 * (1/3)^(^n^-^1^).[/tex]

Thus, the final draft written in functional form is presented as:

What is a parabola?

A parabola is a mirror-symmetrical, nearly U-shaped planar curve in mathematics. It corresponds to a number of seemingly dissimilar mathematical descriptions, all of which can be shown to define the same curves.

We are given a function as f(x) = - (x+3) (x + 1).

Now, on simplifying the equation, we get

⇒ f(x) = - (x+3) (x + 1)

⇒ f(x) = - ([tex]x^{2}[/tex] + x + 3x + 3)

⇒ f(x) = - ([tex]x^{2}[/tex] + 4x + 3)

Answer:

$15000 was invested in CDs, $50000 was invested in bonds, and $30000 was invested in stocks.

Step-by-step explanation:

Let x be the amount invested in CDs. Then, the amount invested in bonds is x + 35000. The remaining amount invested in stocks is 95000 - (x + x + 35000) = 25000 - x.

The annual income from CDs is 0.0475x dollars. The annual income from bonds is 0.042(x + 35000) dollars. The annual income from stocks is 0.112(25000 - x) dollars.

The total annual income from all three investments is $6845: 0.0475x + 0.042(x + 35000) + 0.112(25000 - x) = 6845

Solving for x gives: x = $15000

Therefore, $15000 was invested in CDs, $50000 was invested in bonds, and $30000 was invested in stocks.

The cost of painting the entire surface area of the pyramid, including its square base, is approximately $85.44.

What is the cost of painting?

The Great Pyramid of Giza has a square base, so the surface area of the base is simply the area of a square with side length 1.6 meters:

Area of base = (1.6 m)² = 2.56 m²

To find the surface area of the rest of the pyramid, we need to find the area of each of the four triangular faces. Each face is a right triangle with one leg equal to the slant height of the pyramid (which we can find using the Pythagorean theorem) and the other leg equal to half the length of one side of the base.

The slant height can be found using the Pythagorean theorem:

slant height = √((height)² + (1/2 × base)²)

slant height = √((2.4)² + (0.8)²) ≈ 2.53 meters

Then, the area of one triangular face is:

Area of triangular face = (1/2)baseheight

Area of triangular face = (1/2)(1.6 m)(2.53 m) ≈ 2.03 m²

Since there are four triangular faces, the total surface area of the pyramid is:

Total surface area = 4 × (Area of triangular face) + (Area of base)

Total surface area = 4 × (2.03 m²) + 2.56 m²

Total surface area ≈ 10.68 m²

Therefore, the cost of painting the entire surface area of the pyramid at a rate of $8 per square meter is approximately:

Cost = Total surface area × Cost per m²

Cost = 10.68 m² × $8/m²

Cost ≈ $85.44

So, the cost of painting the entire surface area of the pyramid, including its square base, is approximately $85.44.

we would expect about 36 students to score between Sally's score and the mean on the IQ test.

What is frequency distribution?

The gathered data is arranged in tables based on frequency distribution. The information could consist of test results, local weather information, volleyball match results, student grades, etc. Data must be presented meaningfully for understanding after data gathering. A frequency distribution graph is a different approach to displaying data that has been represented graphically.

We can use the normal distribution formula to calculate the number of students who would be expected to score between Sally's score and the mean:

z = (x - μ) / σ

where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.

First, we need to calculate the z-score for Sally's score:

z = (114 - 100) / 12 = 1.17

To find the number of students who would be expected to score in this range, we multiply this proportion by the total number of students:

Answer:

Algebraic expression:

y - 3 - (5y - 6)

Simplified: -4y + 3

Step-by-step explanation:

"Subtract 5y−6 from y−3" means the 5y-6 is being taken away from the y-3.

y-3 up front and then minus 5y-6. Use parenthesis to keep things organized.

(y-3) - (5y-6)

This is the algebraic expression.

well, tbh, we don't really need the first set of parenthesis.

y-3 - (5y-6)

This is good enough.

Then, to simplify use distributive property. That minus that we wrote in the middle, it has to go to both the 5y and also to the -6.

y-3 - 5y - -6

= y - 3 - 5y + 6

combine like terms

The hyperbola equation centered at the origin with the vertices is x²/(t² + 22) - y²/(t² - 27) = 1

Because the hyperbola is centered at the origin, its standard form equation is:

(x²/a²) - (y²/b²) = 1

Where a denotes the distance between the center and the vertices and b denotes the distance between the center and the co-vertices.

Because the distance between the center and each vertex is √(t² + 72),

We get:

√(t² + 72) = a√(c² - a²) is the distance between the center and each focus, where c is the distance between the center and each focus.

We know that the distance between the center and each focus is √(27),

Thus we can calculate:

√(27 - a²) = √(27 - (t² + 72))

When we simplify, we get:

27 - a² = 27 - t² - 49

a² = t² + 22

When a² is substituted, we get:

(x²/(t² + 22)) - (y²/b²) = 1

Now we must locate b.

Because the distance between the center and each co-vertex is b, we get:

√(a² - 72) = b

√(t² + 22 - 49) = b

√(t² - 27) = b

When b² is substituted, we get:

(x²/(t² + 22)) - (y²/(t² - 27)) = 1

As a result, the hyperbola equation is: x²/(t² + 22) - y²/(t² - 27) = 1

Part a: x intercepts are (4.414, 0) and (1.586,0) and y intercept = (0, 7).

Part b: From the graph, vertex = (3, -2).

In mathematics, a quadratic equation is a second-degree polynomial with the conventional form ax² + bx + c = 0, where a, b, and c are mathematical coefficients and a 0. Second degree refers to an equation where at least one term has been raised to a power of two. The value of the variable x in a quadratic equation is unknown, so we must discover the answer.

Given quadratic function for the macroeconomic variable

Q(x) = x² − 6x + 7.

Part a: x and y intercept:

x-intercept occurs when the function becomes zero.

Put Q(x) = 0

0 = x² − 6x + 7.

Find the factors:

x² − 6x + 7 = 0

a = 1 , b = -6 , c = 7 using the quadratic formula.

x = [-b ± √(b² - 4ac)]/ 2a

x = [6 ± √(36 - 4*1*7)]/ 2*1

x = 3 ± √2

Now,

x = 3 + √2

x = 4.414

and x = 3 - √2 = 1.586

Thus, x intercepts are (4.414, 0) and (1.586,0)

Y-intercept, when x = 0

Q(x) = 0² − 6(0) + 7.

Q(x) = 7

y intercept = (0, 7)

Step-by-step explanation:

First you need to see how much London even practices in one week. So we will divide the total minutes (t) 525 from the total weeks (w) 3:

t / 3 = m

where m equals the amount of minutes London practices in 1 week.

1) rewrite:

t / 3 = m

2) plug in variables:

525 / 3 = m

3) divide:

525 / 3 = 175

Therefore every week, London practices for 175 minutes.

Secondly, we are going to add 1 more week (175) to the total minutes London spent practicing for the 3 weeks (525).

t = m + m

Where t = total minutes altogether (4 weeks) and m equals the minutes of the 3 weeks and the minutes of 1 week.

1) rewrite:

t = m + m

2) plug in:

t = 525 + 175

2) add:

t = 700

Therefore, London would practice 700 minutes in 4 weeks if she practices the same amount every week.
