Problem 1
Answer: Arithmetic, common difference = -4-------------------
Explanation:
Pick any term of the sequence, and subtract off the previous term to find that,
term2 - term1 = -12 - (-8) = -12 + 8 = -4term3 - term2 = -16 - (-12) = -16 + 12 = -4term4 - term3 = -20 - (-16) = -20 + 16 = -4Each time we get the same result, so that means we have an arithmetic sequence with common difference -4
This indicates that adding -4 to each term, or subtracting 4 from each term, will generate the next one.
Eg: term2 = term1 - 4 = -8-4 = -12.
==========================================================
Problem 2
Answer: Arithmetic, common difference = 5-------------------
Explanation:
Similar to problem 1, this sequence is also arithmetic because we add on 5 to each term to get the next one
-6+5 = -1-1+5 = 44+5 = 9Or you could subtract adjacent terms as done in problem 1, to find that the common difference is 5.
==========================================================
Problem 3
Answer: Not arithmetic-------------------
Explanation:
Unlike the previous two problems, this sequence is not arithmetic.
We can see that
term2 - term1 = 12 - 3 = 9term3 - term2 = 48 - 12 = 36The gaps of 9 and 36 aren't the same. We need the same common difference between any adjacent terms to have an arithmetic sequence.
This sequence is instead geometric because
term2/term1 = 12/3 = 4term3/term2 = 48/12 = 4term4/term3 = 192/48 = 4Each quotient is 4, showing the common ratio is 4. To find the next term, we multiply the current term by 4. So the next term after 192 would be 4*192 = 768, then 4*768 = 3072 is next, and so on.

The area of the square is 27 inch².
What is Area?The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.
We have side of square is √27 inches.
So, the Area of Square
= side x side
= √27 x √27
= 27 inches²
Thus, the Required Area is 27 inch².

Circuit Training If sin0 =1 and 0 <0< π find 0.
Answer:
[tex]\theta = \frac{\pi}{2}[/tex]
Step-by-step explanation:
Given
[tex]\sin(\theta) = 1[/tex]
[tex]0 < \theta < \pi[/tex]
Required
Find [tex]\theta[/tex]
[tex]0 < \theta < \pi[/tex] implies that [tex]\theta[/tex] is between 0 and 180 degrees
[tex]\sin(\theta) = 1[/tex]
Take arcsin of both sides
[tex]\theta = sin^{-1}(1)[/tex]
This gives:
[tex]\theta = \frac{\pi}{2}[/tex]
Convert to degrees
[tex]\theta = \frac{\pi}{2} * \frac{180}{\pi}[/tex]
[tex]\theta = 90[/tex]
We have:
[tex]0 < \theta < \pi[/tex] or [tex]0 < \theta < 180[/tex]
To get other values of [tex]\theta[/tex]
We use:
[tex]\sin(\theta) = \sin(180 - \theta)[/tex]
Substitute: [tex]\theta = 90[/tex]
[tex]\sin(90) = \sin(180 - 90)[/tex]
[tex]\sin(90) = \sin(90)[/tex]
This means that there are no other values of [tex]\theta[/tex] in the given range

Find the perimeter of the shaded region. Keep answer in exact form. rectangle with two semi circles within it. Semi circle have a diameter of 6 and regtangle has a lenght of 13
Answer:
31.16
Step-by-step explanation:
Perimeter of the shaded portion = Perimeter of the rectangle - Perimeter of the 2 circles
Length of rectangle = 13
Width = 2d
d is the diameter of the circle = 2(6) = 12
Perimeter of the rectangle = 2(L+W)
Perimeter of the rectangle = 2(13+12)
Perimeter of the rectangle = 2(25)
Perimeter of the rectangle = 50
Perimeter of the semi-circle = πd/2
Perimeter of the circle = 3.14(6)/2
Perimeter of the circle = 18.84/2
Perimeter of the 2 circles = 2(18.84)/2
Perimeter of the 2 circles = 18.84
Perimeter of the shaded portion = 50 - 18.84
Perimeter of the shaded portion = 31.16

At a cake sale, David bought 3 cakes and paid $10.50. At the same price, Lisa bought 4 cakes and 8 cookies and paid $14.80. What was the price of a cake and the price of a cookie
Price of a Cake
10.5/3= 3.5
1 Cake = $3 and 5 cents, 3.5
Price of a cookie
3.5*4=14
14 out of 14.80 was the cost of 4 cakes
Which leaves us with 0.8
8/0.8= 0.1
The Price of 1 cookie is 0.1
1 Cake: 3.5

¿En què situaciones usamos los nùmeros enteros positivos y negativos, escribe 2 ejemplos de cada uno? Por favor para ahora hocino me jalan :(
Respuesta:
Los enteros positivos, o números enteros, se utilizan de muchas maneras durante la vida diaria. Los números de carretera se contabilizan junto con los límites de velocidad de la carretera. Los enteros se utilizan para comprender qué velocidad conducir en una carretera determinada. Los números en los relojes se utilizan para entender la hora y para configurar las alarmas del reloj. Hay números en edificios y casas para identificar direcciones y números para los niveles de piso dentro de los edificios. Los mapas utilizan enteros para proporcionar dirección e información. Los enteros negativos pueden ser menos obvios para su uso en la vida cotidiana. Algunos ejemplos de uso negativo de enteros incluyen las lecturas del termómetro, manteniendo la puntuación en un juego de hockey, altitud y bancos. Aunque todos estos ejemplos utilizan enteros positivos, también utilizan enteros negativos. Un termómetro utiliza negativo enteros para representar temperaturas por debajo de cero. En hockey, cuando el otro equipo anota en la línea del primer equipo, es un menos, pero cuando el primer equipo anota, es un plus. La altitud que está por debajo del nivel del mar está representada con números negativos. Los bancos y las cooperativas de crédito representan débitos con enteros negativos y créditos con enteros positivos.

Find the area of the figure to the nearest hundredth.
Step by step please!
Answer:
[tex] \approx 31.63 \: {ft}^{2} [/tex]
Step-by-step explanation:
Area of the figure = 2 times the area of one semicircle with radius (5/2 = 2.5) 2.5 ft + Area of triangle with base 6 ft and height 4 ft.
[tex] = 2 \times \frac{1}{2} \pi {r}^{2} + \frac{1}{2} bh \\ \\ = 3.14 \times {(2.5)}^{2} + \frac{1}{2} \times 6 \times 4 \\ \\ = 3.14 \times 6.25 + 3 \times 4 \\ \\ = 19.625 + 12 \\ \\ = 31.625 \\ \\ \approx 31.63 \: {ft}^{2} [/tex]
