Answer:

  2

Step-by-step explanation:

We assume your recursive formula is ...

  [tex]a_1=2\\a_n=a_{n-1}^2-2[/tex]

Using this to find a4, we get ...

  [tex]a_2=a_1^2-2=2^2-2=2\\a_3=a_2^2-2=2^2-2=2\\a_4=a_3^2-2=2^2-2=2\\\\\boxed{a_4=2}[/tex]

Answer:

If you were to fully simplify it would technically be 1/2 as 4/8 is correct but can be further rounded down

Step-by-step explanation:

1/8 x 4 = 4/8

4/8 ÷ 4 = 1/2

Solve inequality:

Highlight the points to the right from -5

Answer:

[tex]n>-5[/tex]

Step-by-step explanation:

−105<−7(5−2n)

Divide both sides by −7. Since −7 is negative, the inequality direction is changed.

[tex]\frac{-105}{-7}[/tex] > 5−2n

Divide −105 by −7 to get 15.

15>5−2n

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

5−2n<15

Subtract 5 from both sides.

−2n<15−5

Subtract 5 from 15 to get 10.

−2n<10

Divide both sides by −2. Since −2 is negative, the inequality direction is changed.

n>[tex]\frac{10}{-2}[/tex]

Divide 10 by −2 to get −5.

n>−5

The correct statement is the point (1, 4) means the 1st term of the sequence is 4. The point (2,3) means the 2nd term and so on

Given the function that represents a given given graph a f(x) = -x + 5

For the first term of the sequence, x = 1. Substitute into the function;

f(1) = -1 + 5

f(1) = 4

This shows that the point (1.4) means the 1st term of the sequence is 4.

For the second term, x = 2

f(2) = -2 + 5

f(2) = 3

This shows that the point (2, 3) means the 2nd term of the sequence is 3.

Are they a system or separate inequalities? I'm not sure but either way I will solve each:

[tex]\begin{bmatrix}-3x+5>20\\ \frac{1}{2}x-12<6\end{bmatrix}[/tex]

[tex]-3x+5>20,\\-3x>15,\\x<-5[/tex]

[tex]\frac{1}{2}x-12<6,\\\frac{1}{2}x<18,\\x<36[/tex]

Now if it were a system, the solution would be x<-5, since x<36 is the restriction. Otherwise just take x<-5 and x<36 independent of each other.

Answer:

x< -5, x<36

Step-by-step explanation:

[tex]-3x+5>20} \atop {\frac{1}{2}x-12<6 }} \right. \\[/tex]

Start with the first equation and solve for x

-3x+5>20

     -5   -5

-3x>15

/-3    /-3

x< -5

Do the second:

[tex]\frac{1}{2}x-12<6[/tex]

     +12    +12

[tex]\frac{1}{2}x[/tex]<18

Answer:

Step-by-step explanation:

Answer:

x = 2±sqrt(2)

Step-by-step explanation:

4x^2 -16 x + 8=0

Move the 8 to the right side by subtracting 8 from each side

4x^2 -16 x + 8-8=0-8

4x^2 -16 x =- 8

Get the x^2 term to have a coefficient of 1 by dividing each term by 4

x^2 -4x = -2

Take the coefficient of x and divide by 2 and then square it

-4/2 = -2    

(-2 )^2 = 4

Add this to each side

x^2 - 4x +4  = -2 +4

Factor the right side into ( x +b/2)^2  where b is the coefficient of x

(x-2)^2 = 2

Take the square root of each side

x-2 = ±sqrt(2)

Add 2 to each side

x = 2±sqrt(2)

Answer:

Perimeter =  28·√2 + 24 feet

Step-by-step explanation:

The dimensions of the initial sheet of plywood are;

The length of the sheet of plywood = 25 ft.

The width of the sheet of plywood = 14 ft.

The shape cut from each corner of the sheet of plywood  = A right triangle

The leg length of each of the cut out right triangles = 7 ft.

The number of leg lengths of the right triangle cut from the length side of the initial sheet of plywood = 2

The length of the parallel sides of the remaining hexagonal piece of plywood = Initial length of the plywood - 2 × The leg length of the cut out right triangle

∴ The length of the parallel sides of the remaining hexagonal piece of plywood = 26 ft. - 2 × 7 ft.  = 12 ft.

The other side length of the remaining hexagonal piece of plywood = The hypotenuse side of the cut out right triangle

The hypotenuse side of the cut out right triangle = √((7 ft.)² + (7 ft.)²) = 7·√2 ft.

∴ The other side length of the remaining hexagonal piece of plywood = 7·√2

The number of side lengths in the remaining hexagonal piece of plywood = 4

The perimeter of the remaining hexagonal piece of plywood = 2 × The length of the parallel sides + 4 × The other side lengths

∴ The perimeter of the remaining hexagonal piece of plywood = 2 × 12 ft. + 4 × 7·√2 = (28·√2 + 24) ft.

The perimeter of the remaining hexagonal piece of plywood = (28·√2 + 24) feet

Answer:

35 sweets

Step-by-step explanation:

Ratio of blue to green sweets is 2:7 Ration of green to red sweets is 3:1 There are less than 140 sweets in the bag Greatest amount of red sweets

Ration of green to red sweets is 3:1

Total Proportion = 3 + 1 = 4

Total number of sweet = > 140 sweets

The greatest amount of red sweets =

1/4 × 140 = 35 sweets

Answer:

$512.5

Step-by-step explanation:

Given data

P= $500

R=2.5%

T= 1 year

The compound interest formula is

A=P(1+r)^t

substitute

A=500(1+0.025)^1

A=500(1.025)

A=500*1.025

A=$512.5

Hence the balance is $512.5

Answer:

$5.94

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...

  0.10d + 0.25(23 -d) = 4.70

  -0.15d + 5.75 = 4.70

  1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides

  7 = d . . . . . . . . . . . . . . divide by 0.15

There were 7 dimes in the change purse.

There were 23-7 = 16 quarters.

Answer:

The answer is 100ft2 I think

Answer:

A) 24

B) 24

Step-by-step explanation:

A) equilateral triangle means that all sides are equal

so each side is = 24 because the perimeter = 72

72/3= 24

B) 1 side = 24 and they gave you that 10+7h = 24

so h = 2

so hight of triangle = 2

Area = 1/2(b)(h)

so 24(2)(0.5) = 24
