The line plot shows the different lengths of nails in your toolbox. If you take all the nails
sukhopar [10]
The nails less than 2 inches long are the ones that are 1/2”, 1”, and 1 1/2”, if I am reading the table correctly.

4 x 1/2” = 2”
2 x 1” = 2”
2 x 1 1/2” = 3”
2 + 2 + 3 = 7 inches

You have a wire that is 29 cm long. you wish to cut it into two pieces. one piece will be bent into the shape of a square. the o
Nostrana [21]
C = circumference of circle
p = perimeter of square
c + p = 29
p = 29 - c

side of square = (29 - c)/4
radius of circle = c/(2pi)

a = side^2 + (pi)r^2

a = ((29 - c)/4)^2 + pi * (c/(2pi))^2

a = (1/16)(841 - 58c + c^2) + (c^2/(4pi^2)) * pi

a = 52.5625 - 3.625c + c^2/16 + c^2/(4pi)

Since the 2nd degree term has a positive coefficient is positive, this has a graph that is a parabola opening up. It has a minimum value.

We take the derivative of the area expression and set equal to zero to find the minimum circumference.

da/dc = -3.625 + c/8 + (c/(2pi)) = 0

c = 12.76

Answer: 12.76 cm

On a coordinate grid the coordinates of vertices p and q for polygon pars are p(5,4) and q(-2,4) what is the length of side pq?
Mariulka [41]

Answer:

pq = 7

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = p(5, 4) and (x₂, y₂ ) = q(- 2, 4)

pq = \sqrt{(-2-5)^2+(4-4)^2}

     = \sqrt{(-7)^2+0^2}

     = \sqrt{49}

     = 7

Write a quadratic equation in standard form that has 5 3 and 7 3 as its roots. A) 9x2 − 36x + 35 = 0 B) 9x2 + 36x − 35 = 0 C) 9x
Serggg [28]

Answer:

Option A)

9x^2 - 36x + 35 = 0

Step-by-step explanation:

We are given the following in the question:

Roots of quadratic equation are:

\alpha = \dfrac{5}{3}, \beta = \dfrac{7}{3}

The sum of the roots and the product of the roots can be calculated as:

\alpha + \beta = \dfrac{5+7}{3} = 4\\\\\alpha\beta = \dfrac{5}{3}\times \dfrac{7}{3} = \dfrac{5}{9}

Standard form of quadratic equation:

x^2-(\alpha + \beta)x+\alpha\beta = 0

Putting values, we get,

x^2 - 4x + \dfrac{35}{9} = 0\\\\9x^2 - 36x + 35 = 0

is the required quadratic equation.

Thus, the correct answer is

Option A)

9x^2 - 36x + 35 = 0
