The formula for interior angle of any polygon is (n-2) x 180 / n where n is the number of sides.

An octagon has 8 sides:

Part A.
interior angle = (8-2) x 180 /8

Interior angle = 135 degrees

Part B.
3x -57 = 135

Add 57 to both sides:

3x = 192

Divide both sides by 3:

X = 64

The vertex of g(x) = [tex]\rm 3x^2 - 12x + 7[/tex] is (2, -5), the correct option is C.

The vertex of a parabola is the highest or lowest point, also known as the maximum or minimum of a parabola.

The standard equation of the vertex of the parabola is;

[tex]\rm a(x - h)^2 + k[/tex]

Where h and k are the coordinates of the vertex of the parabola.

The given expression is;

[tex]\rm =3x^2 - 12x + 7\\\\= 3(x^2 - 4x) + 7\\\\ = 3[ (x - 2)^2 - 4)] + 7\\\\= 3(x - 2)^2 - 12 + 7\\\\= 3(x - 2)^2 - 5[/tex]

On comparing with the standard form of vertex of the parabola

h = 2 and k = -5

Hence, the vertex of g(x) = [tex]\rm 3x^2 - 12x + 7[/tex] is (2, -5).

The equation that can be used to solve for n, the smaller of the two numbers would be n² + n - 210 = 0.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

If we use n to be the smaller number of two integer numbers, then the next consecutive number is n + 1.

The product of those two numbers would become n × (n + 1) = n (n + 1).

Half of that product is n (n + 1) / 2.

And the question states that the equation is equal to 105, so the equation becomes,

n (n + 1) / 2 = 105

Now we have to simplify that equation until we get an expression equal to one of the choices,

Multiply both sides by 2

n (n + 1) = 210

n² + n = 210

Subtract 210 from both sides

n² + n - 210 = 0

Thus, the equation formed is the quadratic equation.

Step-by-step explanation:

[tex]-24 + 12d= 2(d-3)+22\\\\\implies -24 +12d = 2d-6 +22\\\\\implies 12d-2d-24+6-22 = 0\\\\\implies 10d -40=0 \\\\\implies d = \dfrac{40}{10} = 4\\\\[/tex]

Answer:

Step-by-step explanation:

In order to solve this equation, you must isolate it on one side of the equation.

Use the distributive property.

Distributive property:

⇒ -24+12d=2(d-3)+22

Multiply.

⇒ 2(d-3)+22

⇒ 2d-2*3

⇒ 2*3=6

⇒ 2d-6

Rewrite the problem down.

⇒ 2d-6+22

⇒ -6+22=16

⇒ 2d+16

⇒ -24+12d=2d+16

Then, you add by 24 from both sides.

⇒ -24+12d+24=2d+16+24

Solve.

⇒ 12d=2d+40

Subtract by 2d from both sides.

⇒ 12d-2d=2d+40-2d

Solve.

⇒ 12d-2d=10d

⇒ 10d=40

Divide by 10 from both sides.

⇒ 10d/10=40/10

Solve.

Divide the numbers from left to right.

⇒ 40/10=4

The ellipse with the equation stated above is:
Position I (Option C )

An ellipse is a circle that has been extended in one direction such that it is no longer a circle but an oval.

Solution

In order to determine the position of the ellipse with the above equation, we can start by simplifying the equation.

Hence, 9x² + 16y = 144 becomes

x²/16 + y²/9 =  1 (We arrive at this by dividing both sides of the equation by 144);

The x-axis is the major axis because the biggest denominator is under the x² term.

Thus the coordinates of the vertices are as follows:

(± a, 0); (0, ± b)

Hence:

a² = 16 → a = 4

b² = 4 → b = 2

Hence the coordinates are:

(± 4, 0); (0, ± 2)

Given the above, the eccentricity is given as:

e = √(1 - (3/4)^2 = (√7)/4 = 0.6614378

Hence the ellipse is: 0.66

Step-by-step explanation:

first, we need to divide 600 by 50, to get them organized for the best packages. 600/50 = 12.

then, we multiply that (the 12) by the cost ($12/ea) so 12*12 which is $144 if they use the bundling.

Answer:

[tex]a_{n}[/tex] = 11 [tex](2)^{n-1}[/tex]

Step-by-step explanation:

the nth term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

given a₁ = 11 and a₄ = 88 , then

11 r³ = 88 ( divide both sides by 8 )

r³ = 8 ( take cube root of both sides )

r = [tex]\sqrt[3]{8}[/tex] = 2 , then the nth term is

[tex]a_{n}[/tex] = 11 [tex](2)^{n-1}[/tex]

2 cats were adopted.

Step-by-step explanation:

When finding a percentage of something, heres a trick. Just take the number you taking the perccentage of, and mutiply it by the percentage. In this case, 24*12.

24*12 = 288.

Now take that new number and divide it by 100. Now you have your answer. In this case,

288/100 = 2.88.

Becuase these are cats, we can't have or adopt half of one XD. You can't adopt half of a cat, so we round it down to 2. Meaning, 2 cats were adopted.
