Find the circumstance of a circle with the diameter of 13 meters use 3.14 as an approximation

Answers

Answer 1

Answer:

okay so the circumference is 40.82m

[tex]circumference = 2\pi \: \times r \\ = 2 \times 3.14 \times 6.5 \\ = 40.82m[/tex]

Answer:

Slope formula:

        ____________________________________

RUN: x2(second x-coordinate) - x1(first x-coordinate)

y2 - y1 / x2 - x1

Plug in what we have in the order given in the formula:-

 12 - 6           6

______ = ______, which simplifies to 2.

  7 - 4            3

Therefore, 2 is the slope of this equation.

Answer:

Slope: 2

Step-by-step explanation:

Given points:

(4, 6)(7, 12)

Slope formula: (y₂ - y₁)/(x₂ - x₁)

1. Substitue the coordinates of the points in the formula, which will determine the slope of the two points:

[Formula] Slope = (y₂ - y₁)/(x₂ - x₁)[Substitute] Slope = (12 - 6)/(7 - 4)

2. Simplify the fraction. The quotient will be the slope of the line.

[Simplify] Slope = (6)/(3) = 2

Thus, the slope of the line is 2.

Grandma baked 96 cookies and gave them to her grandchildren. One of the grandchildren, Cindy, received c fewer cookies than she would have received had all of the cookies been evenly divided among the 8 grandchildren.How many cookies did Cindy receive? Write your answer as an expression.

Answers

Answer: 29 cookies.

Step-by-step explanation: 96/8=32       32-3=29        boom. maths.

The number of cookies baked by Grandma= 96

If she divides them evenly amount 8 children, then by division operation the number of cookies received by each child = (number of cookies) ÷ (number of children)

= (96) ÷ (8) = 12

Since, Cindy, received c fewer cookies than she would have received had all of the cookies been evenly divided among the 8 grandchildren.

Hence, the number of cookies received by Cindy = 12-c

How to analyze second order polynomials graphically

Graphically speaking, second order polynomials are represented by parabolas. In this question we must interpret the graphs to find all the required information.

Question 1

The solutions to the graph are those values of x such that the graph goes through the x-axis and the axis of symmetry is a line that goes through the vertex ot the parabola and is perpendicular to the width of the curve.

Thus, the solutions to the graph are x = 2 and x = 4 and the axis of symmetry is x = 3. [tex]\blacksquare[/tex]

Question 3

The vertex is the extreme point of a parabola, which may be a minimum or a maximum, but never both. The vertex of the parabola is located at (x, y) = (-3, 5). [tex]\blacksquare[/tex]

Question 4

A parabola cannot have both a minimum and maximum point because it is only bounded by its vertex. [tex]\blacksquare[/tex]

Question 5

The domain of the function is defined by the set of x-values such that the function exists. Thus, the domain of the quadratic function is [tex]x \in \mathbb{R}[/tex]. [tex]\blacksquare[/tex]

Question 6

The range of the function is defined by the set of y-values such that the function exists. Thus, the range of the quadratic function is [tex]y \in [-5, + \infty)[/tex].  [tex]\blacksquare[/tex]

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.

We need to find the product of 296 and 2.423

296 x 2.423 = 717.20

Answer:

a) (2x + 1)(3x - 4)

b) 546

Step-by-step explanation:

a)

We need to try to factor the polynomial.

6(-4) = -24

6x² - 8x + 3x - 4 = 2x(3x - 4) + 1(3x - 4) =

= (2x + 1)(3x - 4)

b)

6(10)² - 5(10) - 4 = 600 - 50 - 4 = 546

Answer:

(a) when x = 2:    width = 2 units   and     length = 5 units

(b) 546 units²

Step-by-step explanation:

Given expression:

[tex]6x^2-5x-4[/tex]

Part (a)

To factor a quadratic in the form [tex]ax^2+bx+c[/tex]

Find 2 two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]

Two numbers that multiply to -24 and sum to -5:  -8 and 3

Rewrite [tex]b[/tex] as the sum of these 2 numbers:

[tex]\implies 6x^2+3x-8x-4[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies 3x(2x+1)-4(2x+1)[/tex]

Factor out the common term [tex](2x+1)[/tex]:

[tex]\implies (3x-4)(2x+1)[/tex]

Therefore:

[tex]\implies x=\dfrac{4}{3}, \: x=-\dfrac{1}{2}[/tex]

As distance is positive, [tex]x > \dfrac{4}{3}[/tex]

Let [tex]x=2[/tex]

[tex]\implies (3(2)-4)(2(2)+1)[/tex]

[tex]\implies (2)(5)[/tex]

Therefore, possible dimensions of the rectangle are:

width = 2 units

length = 5 units

Part (b)

Substitute [tex]x=10[/tex] into the equation:

[tex]\begin{aligned}\implies 6(10)^2-5(10)-4&=600-50-4\\&=546\end{aligned}[/tex]

The formula for calculating the area of a rectangle is expressed as:

A  = length * width

Let the length be 51 and the width be 102 yd such that:

Area of the grass = 51 * 102
Area of the grass = 5202 square yard

If it costs $.25 per square yard to seed an area of grass, the price fror the area inside the track is:

Victoria is at an elevation of 150 feet. She hikes down to an elevation of 120 feet in 40 minutes.
Then she hikes down to an
elevation of 100 feet in 30 minutes.

What is her average rate of descent, in feet per minute, from 150 feet to 120 feet?

Answers

The Victoria's average rate of descent by hiking down from an elevation of 150 feet to an elevation of 120 feet in 40 minutes is equal to 0.75 feet per minute.

How to determine the average rate of descent of a hiker

Geometrically speaking, the average rate of descent (r), in feet per minute, is represented by a secant line, which represents in this case the change in elevation (Δz), in feet, divided by the change in time (Δt). A mathematical description of the formula is shown below:

r = Δz/Δt     (1)

If we know that Δz = 30 ft and Δt = 40 min, then the average rate of descent is:

r = 30 ft/40 min = 0.75 ft/min

The Victoria's average rate of descent by hiking down from an elevation of 150 feet to an elevation of 120 feet in 40 minutes is equal to 0.75 feet per minute. [tex]\blacksquare[/tex]

IM NOT. NNOT SURE BUT I THINK... the area may be 177? if i did it right, please check my equations though!

Step-by-step explanation:

so we first have to find the area of alllll the rectangles/squares in that weird squiggly shape

lets do the top

the width is 15 ft and the length is 5ft

so to find the area you have to do length times with so

A = lw

A = 15(5)

A = 75

so the first shape is 75

now lets do something real quick (im sorry this is all messed up infromation i have a dba (call) in like 16 mins and i gotta hurry. but illl come back if you need more explinations)

let first shape be f

let second shape be s

let third shape be t

let R be the area of the total shape

f + t + s = R

75 + t + s = R

now to find t

so the width would be 9ft and the length would be 8ft

A = lw

A = 9(8)

A = 72

75 + 72 + s = R

now to find s

the width is 5fth and the length is 6ft

A = lw

A = 6(5)

A = 30

now i think we add?

75 + 72 + 30 = R

75 + 102 = R

177 = R

i think the area is 177? (if i remeber how to do this correctly)

btw I will come back later and upload a pic of how i did it if you like. i must go now cause my teacher is gonna ask me civics questions and im so bad at that subject!!!!

Area of trapezium - 12
Finally add both area of square and area of trapezium.
Total area= 12+16=28 cm^2

A = 28 cm²

Step-by-step explanation:

area of square = 4 × 4 = 16 cm²

area of trapezium = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the height and b₁ , b₂ the parallel bases

here h = 2 , b₁ = 8 , b₂ = 4

e)  y = (x + 6)² - 7

f)  y = (x - 2)² + 5

Step-by-step explanation:

Parent equation:  y = x²

Transformed equation:  y = (x - h)² + k

h translates the parabola horizontally

If h > 0 then the translation is h units to the right.

If h < 0 then the translation is h units to the left.

If h = 0 then there is no horizontal translation.

k translates the parabola vertically

If k > 0 then the translation is k units up.

If k < 0 then the translation is k units down.

If k = 0 then there is no vertical translation.

a) The parabola moves 3 units to the right:  

⇒ y = (x - 3)² + 0

⇒ y = (x - 3)²

b) The parabola moves 4 units down:

⇒ y = (x - 0)² - 4

⇒ y = x² - 4

c) The parabola moves 2 units left:  

⇒ y = (x + 2)² + 0

⇒ y = (x + 2)²

d) The parabola moves 5 units up:  

⇒ y = (x - 0)² + 5

⇒ y = x² + 5

e) The parabola moves 7 units down and 6 units left:  

⇒ y = (x + 6)² - 7
