What is the area of this polygon?

40 cm2
18 cm2
16 cm2
24 cm2

Answer:

2(x+1)²-3

Step-by-step explanation:

Using the vertex formula we can write the follwoing equation

y=a(x+1)²-3

We need to solve for a

we know that when x= 2 y = 15

So we can write

15=a(2+1)²-3

15=9a-3

18=9a

a=2

Which means our final equation is

2(x+1)²-3

in standard form (just in case)

2x²+4x-1

Answer:

[tex] x = \dfrac{3+\sqrt{29}}{2},\dfrac{3-\sqrt{29}}{2}[/tex]

Step-by-step explanation:

This kinda Questions can be easily done using the Quadratic formula or Shreedhacharya's Formula . Which is used to find the roots of a quadratic equation in Standard form of ax² + bx +c = 0 .

Wrt . Standard form ,

[tex]\implies x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\implies x = \dfrac{-3\pm \sqrt{3^2-4(1)(5)}}{2(1)}\\\\\implies x = \dfrac{-3\pm \sqrt{9+20}}{2} \\\\\implies \boxed{\boxed{ x = \dfrac{3+\sqrt{29}}{2},\dfrac{3-\sqrt{29}}{2}}}[/tex]

This is our required answer.

Answer:

Ten Peaches and five bananas.

Step-by-step explanation

To solve the problem increase the cost by adding more peaches and less by adding more bananas

7 peaches = 3.50

8 bananas = 3.20 + 3.50 = 6.70

We need 30 more cents so add three more peaches

10 peaches = 5

5 x 0.4 = 2

2 + 5 = 7

Answer:

Number 2 is C. 7

Step-by-step explanation:

You have to multiply 5 and 3 you will get 15 then take 15 from 43 you will get 28 then dived 28 by 4 you will get 7.

Answer: C

Step-by-step explanation: a^2 + b^2 = c^2

A. 6^2 + 8^2 = 10^2

B. 12^2 + 35^2 = 37^2

C. 4^2 + 6^2 does not equal 10^2.....(16 + 36 = 52   10^2 = 100)

D. 10^2 + 24^2 = 26^2

The measures of the triangles 4 cm, 6 cm, and 10 cm do not represent a right angle triangle because it does not follow the Pythagoras theorem option (C) is correct.

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

For the triangle sides:

6 cm, 8 cm, and 10 cm

From the Pythagoras theorem:

[tex]10^2=8^2+6^2[/tex]

100 = 100

These sides satisfy the Pythagoras formula.

For the triangle sides:

12 cm, 35 cm, and 37 cm

From the Pythagoras theorem:

[tex]37^2=35^2+12^2[/tex]

1369 = 1369

These sides satisfy the Pythagoras formula.

For the triangle sides:

4 cm, 6 cm, and 10 cm

From the Pythagoras theorem:

[tex]10^2=6^2+4^2[/tex]

100 ≠ 52

These sides do not satisfy the Pythagoras formula.

For the triangle sides:

10 cm, 24 cm, and 26 cm

From the Pythagoras theorem:

[tex]26^2=24^2+10^2[/tex]

676 =  676

These sides satisfy the Pythagoras formula.

Thus, the measures of the triangles 4 cm, 6 cm, and 10 cm do not represent a right angle triangle because it does not follow the Pythagoras theorem option (C) is correct.

Step-by-step explanation:

Answer:

The values of x and y are 23.83 and 31.1.

Step-by-step explanation:

Given that,

Perpendicular = 20 units

Angle, [tex]\theta=40^{\circ}[/tex]

We need to find the values of x and y.

Using trigonometry,

[tex]\tan(40)=\dfrac{20}{x}\\\\x=\dfrac{20}{\tan(40)}\\\\x=23.83[/tex]

To find y use Pythagoras theorem,

[tex]y^2=23.83^2+20^2\\\\y=31.1[/tex]

So, the values of x and y are 23.83 and 31.1.

Answer:

see explanation

Step-by-step explanation:

step 2 : 4x + 4 - 2x = - 6x + 6 + 14

Simplify both sides by collecting like terms ← what was done

step 3 : 2x + 4 = - 6x + 20

------------------------------------------

step 4 : 8x + 4 = 20

Subtract 4 from both sides ← what was done

8x = 16

Answer: 53 cm

Step-by-step explanation:

Answer: 53 cm

Step-by-step explanation:

Answer:

First angle = x

Second angle = x - 32

We know that, complementary angles form => 90°

So,

[tex]x + x - 32= 90 \\ 2x = 90 + 32 \\ 2x = 122 \\ x = \frac{122}{2} \\ x = 61[/tex]

First angle,

=> x = 61°

Second angle

[tex]x - 32 \\ = 61 - 32 \\ = 29[/tex]

Second angle,

=> 29°

Answer:

The radius is the line from the center of the circle to the side of the circle

Step-by-step explanation:

Answer:

Count lines of symmetry

Step-by-step explanation:

To find a line of symmetry, look for two halves of the shape that are mirror images of each other. The right half of the shape is the mirror image of the left half. So, the vertical line that passes through the middle is a line of symmetry. A figure has rotational symmetry if it can be rotated by an angle between 0° and 360° so that the image coincides with the preimage. The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself.

Radius

A radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

Answer:

El orden es;

1) Cuadrilátero, 2) Rombo, 3) Paralelogramo, 4) Rectángulo, 5) Cuadrado

Step-by-step explanation:

Los términos dados son;

Cuadrilátero; Una forma con cuatro lados

Rombo; Un cuadrilátero con cuatro lados iguales

Cuadrado; Un cuadrilátero con cuatro lados iguales y cuatro ángulos iguales y dos lados paralelos opuestos

Rectángulo; Un cuadrilátero con cuatro ángulos rectos y dos lados paralelos opuestos

Paralelogramo; Un cuadrilátero con un par de lados paralelos opuestos

Observamos que todos los términos son cuadriláteros, por lo tanto, el cuadrilátero es el primer término

Por lo tanto, tenemos,

La primera forma es el cuadrilátero,

El cuadrilátero se transforma en un rombo (un cuadrilátero con lados iguales)

El ángulo del rombo se ajusta para dar un paralelogramo

El ángulo de paralelogramo dado cuatro ángulos iguales de 90 ° para dar un rectángulo

El rectángulo se ajusta para dar un cuadrado con todos los lados iguales
