Find two positive integers that satisfy the requirement.

Answer:

The two positive integers that satisfy the requirement are 21 and 23

Step-by-step explanation:

Let

x ----> the first consecutive odd integer

x+2 ---> the second consecutive odd integer

we know that

x(x+2)=483

Apply distributive property left side

x^2+2x=483

x^2+2x-483=0

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^2+2x-483=0

so

a=1\\b=2\\c=-483

substitute in the formula

x=\frac{-2(+/-)\sqrt{2^{2}-4(1)(-483)}} {2(1)}

x=\frac{-2(+/-)\sqrt{1,936}} {2)}

x=\frac{-2(+/-)44} {2)}

x=\frac{-2(+)44} {2)}=21

x=\frac{-2(-)44} {2)}=-23

so

x=21

x+2=23

therefore

The two positive integers that satisfy the requirement are 21 and 23

On the coordinate plane below, Point P is located at (2,-3), and point Q is located at (-4,4).
Semenov [28]

Answer:

Approximately 9 units.

Step-by-step explanation:

To find the distance between two ordered pairs, we can use the distance formula. The distance formula is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Let (2,-3) be x₁ and y₁ respectively, and let (-4,4) be x₂ and y₂, respectively.

d=\sqrt{(-4-2)^2+(4--3)^2} \\d=\sqrt{(-6)^2+(7)^2} \\d=\sqrt{36+49} \\d=\sqrt{85}\approx9

Hi, please help me me by demonstrating how to solve these 2 questions step by step :)
myrzilka [38]

The given height of the shape is calculated to be 1,895.04 inches.

<h3>How to solve for the height</h3>

We have the following details required to solve this problem

The distance b1 = 800 m

The angle of elevation β1 = 50°

distance b2 = 1450 m

- The new angle of elevation  α = 33°

We first have to find the height of h1

800 x tan 50 degrees

= 953.40

The height of h2

1450 x tan 33

= 941.641

The height of the shape is the sum of the heights of h1 and h2

953.40 + 941.641

= 1,895.04

Hence the height of the shape is given as 1,895.04 inches.

In a family, each brother has as many sisters as broth, but
irina [24]

Answer: 4 brothers and 3 sisters for a total of 7 siblings

Step-by-step explanation:

Let No. of boys = x

Let No. of girls = y

<u>Each boy has as many brothers as sisters</u>

Hence, (x - 1) = y

Rearranging we get,

x - y = 1 ……….(1)

<u>Now, each girl has twice as many brothers as that of sisters</u>

Hence, 2 * (y - 1) = x

Solving the bracket we get, 2y - 2 = x

Rearranging we get,

-x + 2y = 2 ……….(2)

Adding (1) and (2) using the elimination method, we get

x - y = 1

-x + 2y = 2

<u>y = 3</u>

Substituting value of Y in equation (1),

x - 3 = 1

Solving this we get,

x = 4

Thus, No. of Boys = 4, No. of Girls = 3 and No. of Siblings in the family = 7
