Answer:

Only Hiroki

Step-by-step explanation:

His formula makes the most sense to the sequence.

Given that the recursive formula for a sequence is [tex]a_n=a_{n-1}+2n[/tex]

The first term of the sequence is [tex]a_1=4[/tex]

We need to determine the first four terms of the sequence.

Second term:

The second term of the sequence can be determined by substituting n = 2 in the recursive formula.

Thus, we have;

[tex]a_2=a_{2-1}+2(2)[/tex]

[tex]a_2=a_{1}+2(2)[/tex]

[tex]a_2=4+4[/tex]

[tex]a_2=8[/tex]

Thus, the second term of the sequence is 8.

Third term:

The third term of the sequence can be determined by substituting n = 3 in the recursive formula.

Thus, we have;

[tex]a_3=a_{3-1}+2(3)[/tex]

[tex]a_3=a_{2}+2(3)[/tex]

[tex]a_3=8+6[/tex]

[tex]a_3=14[/tex]

Thus, the third term of the sequence is 14.

Fourth term:

The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.

Thus, we have;

[tex]a_4=a_{4-1}+2(4)[/tex]

[tex]a_4=a_{3}+2(4)[/tex]

[tex]a_4=14+8[/tex]

[tex]a_4=22[/tex]

Thus, the fourth term of the sequence is 22.

Hence, the first four terms of the sequence is 4, 8, 14, 22.

To create an arithmetic sequence using the given functions, we add the functions together and substitute the desired term. The 31st term of the arithmetic sequence is -49.

To combine the functions f(n) = 11 and g(n) = -2(n - 1) into an arithmetic sequence, we need to find the common difference between the terms. The common difference between the terms in an arithmetic sequence is obtained by subtracting one term from the previous term. In this case, the common difference is g(n). So, the arithmetic sequence can be expressed as an = f(n) + g(n).

For the 31st term, we substitute n = 31 into the equation and calculate:

a31 = f(31) + g(31)

a31 = 11 + [-2(31 - 1)]

a31 = 11 + [-2(30)]

a31 = 11 + [-60]

a31 = -49

Therefore, the 31st term of the arithmetic sequence an is -49.

1) f(0)= -6 , f(2)=  -12, f(-1)=  0, f(6)= 0

2) f(0)= -12 , f(2)= -8 , f(-1)= -14 , f(6)= 168

3) f(0)= 5 , f(2)=  20, f(-1)= 2.5 , f(6)= 320

Step-by-step explanation:

1) The given function is f(x) = x² – 5x – 6.

To find the values of  f(0) , f(2),  f(-1),  f(6) :

Substitute x=0 in f(x) = x² – 5x – 6

f(0) = -6

Therefore, f(0) = -6

Substitute x=2 in f(x) = x² – 5x – 6

f(2)  = (2)² -5(2)-6

⇒ 4-10-6

⇒ 4-16

⇒ -12

Therefore, f(2) = -12

Substitute x= -1 in f(x) = x² – 5x – 6

f(-1)  = (-1)² - 5(-1) -6

⇒  1+5-6

⇒ 6-6

⇒ 0

Therefore, f(-1)  = 0

Substitute x= 6 in f(x) = x² – 5x – 6

f(6) = (6)² - 5(6) -6

⇒ 36 -30 -6

⇒ 36-36

⇒ 0

Therefore, f(6) = 0

2) The given function is f(x) = x³– x²–12.

To find the values of  f(0) , f(2),  f(-1),  f(6) :

Substitute x=0 in f(x) = x³– x²–12

f(0) = -`12

Therefore, f(0) = -12

Substitute x= 2 in f(x) = x³– x²–12

f(2)  = (2)³ - (2)² -12

⇒ 8-4-12

⇒ 8-16

⇒ -8

Therefore, f(2)  = -8

Substitute x= -1 in f(x) = x³– x²–12

f(-1)  = (-1)³ - (-1)² -12

⇒  -1-1-12

⇒ -14

Therefore, f(-1)  = -14

Substitute x= 6 in f(x) =  x³– x²–12

f(6) = (6)³ - (6)² -12

⇒ 216 -36 -12

⇒ 216-48

⇒ 168

Therefore, f(6) = 168

3) The given function is f(x) = [tex]5.24^{x}[/tex]

To find the values of  f(0) , f(2),  f(-1),  f(6) :

Substitute x=0 in f(x) = [tex]5.2^{x}[/tex]

f(0) = 5 × [tex]2^{0}[/tex]

Any number with power zero is 1.

f(0) = 5

Therefore, f(0) = 5

Substitute x=2 in f(x) = [tex]5.2^{x}[/tex]

f(2) = 5 × 2²

⇒ 5×4

⇒ 20

Therefore, f(2) = 20

Substitute x= -1 in f(x) = [tex]5.2{x}[/tex]

f(-1)  = [tex]5\times2^{-1}[/tex]

⇒ 5 × 1/2

⇒ 5 × 0.5

⇒ 2.5

Therefore, f(-1)  = 2.5

Substitute x= 6 in f(x) =  [tex]5.2^{x}[/tex]

f(6) = [tex]5\times 2^{6}[/tex]

⇒ 5 × 64

⇒ 320

Therefore, f(6) = 320

Answer:

a = -3

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.

Divide -8 from both sides:

(-8a)/-8 = (24)/-8

a = 24/-8

a = -3

a = -3 is your answer.

Answer:

a = -3 to find this answer divide both sides by -8

What is Linear Function? - Equation, Graph, Definition

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.

Answer:

340 degrees

Step-by-step explanation:

So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).

So the circumference of a circle = 2pi(r)

This means:

6 = 2pi(r)

Which means that

r = 6/2pi or r = 3/pi

Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:

Arc length is defined by: length = θr

Where θ is our angle value.

So lets plug in:

[tex]\frac{17}{3} = (angle)\frac{3}{\pi }[/tex]

Multiply by pi to get:

[tex]\frac{17\pi }{3} = 3(angle)[/tex]

Divide by 3 to get that:

θ = 17pi/9

So if we convert that from radians to degrees we get 340 degrees.

(A) The prism could be a cube with a side length of 10 mm.

(B) It is possible for the length to be 1,000 mm.

(D) It is possible that the length is 2.5 mm.

Explanation:

Volume = l×w×h

where l is the length, w is the width and h is the height

It is possible that the length is 2.5 mm

Then volume = 2.5 × 10 ×40 = 1000 mm³

It is possible for length to be 1000 mm

Then volume = 1000 × 0.1 × 10 = 1000 mm³

The prism could be a cube of length 10 mm

Then volume = 10 × 10 × 10 = 1000 mm³

Step-by-step explanation:

To simplify 2/√(10), multiply the numerator and denominator by √(10) to get √(10)/5. This process removes the square root from the denominator.

To simplify the expression 2/√(10), we rationalize the denominator. This involves removing the square root from the denominator by multiplying the numerator and the denominator by the square root of 10.

So, the simplified form of 2/√(10) is √(10)/5.

Answer:

Step-by-step explanation:first round the fractions then add decide if it goes to 0,1/2,or 1

The best estimate for the sum of 5/6 and 3/7 by rounding to the nearest 0, 1/2, or 1 is 1.5 or 3/2.

To estimate the sum of 5/6 and 3/7, we round each addend to the nearest of the given values: 0, 1/2 (0.5), or 1. Five-sixths is closer to 1 than it is to 1/2 or 0. So, we round 5/6 to 1.

Three-sevenths is closer to 1/2 than to 1 or 0. So, we round 3/7 to 1/2. After rounding, our new equation for estimation is 1 + 1/2.

The best estimate for the sum thus becomes 1 + 1/2 which equals 1.5 or 3/2. This is a quick way to find a rough estimate of the sum without finding a common denominator or adding the actual fractions.

[tex]\:a\:\times \:b\:\times \:\pi[/tex]

The major axis of an ellipse = 25 inches

The minor axis of an ellipse = 4 inches

Thus

The area of the ellipse:

Answer:

D) 5

Step-by-step explanation:

If we multiply 5 and an odd number, the end value will not be 0, 1, and 3. For example,

5 × 1 = 5

5 × 9 = 45

Therefore, in both the product, the end value is 5 and not 0, 1, and 3.

Therefore, option D is correct.

If we multiply 5 by any of the odd number, we can get the end value of 5. The following examples are the valid reasons why we will get 5.

5 × 3 = 15

5 × 5 = 25

So, option A, B, and C are wrong.

Answer:

The perimeter of the polygon are

PQ = 5

RS = 5

PR = √74 = 8.60

QS = √74 = 8.60

QR = 7

Step-by-step explanation:

To calculate the perimeter of a polygon, polygon is like a coordinate with points, to find the length, we use this formula

d = √(x _2 - x_1)^2 + (y_2 - y_1)^2

Let's start from the first two vertices P ( 0 , 4) and Q(5 , 4)

x_1 = 0

y_1 = 4

x_2 = 5

y_2 = 4

PQ = √ ( 5 - 0)^2 + ( 4 - 4)^2

= √ 5^2 + 0^2

= √ 25

= 5

Between R( 5 , -3) and S ( 0 , -3)

x_1 = 5

y_1 = -3

x_2 = 0

y_2 = -3

RS = √ ( 0 - 5)^2 + ( -3 - (-3))^2

= √( -5)^2 + ( -3 + 3)^2

= √ 25 + 0

= √ 25

= 5

Between P( 0 , 4) and R (5 , -3)

x_1 = 0

y_1 = 4

x_2 = 5

y_2 = -3

PR = √( 5 - 0)^2 + ( -3 - 4)^2

= √ 5^2 + (-7)^2

= √ 25 + 49

= √ 74

= 8.60

Between Q ( 5 , 4) and S(0 ,-3)

x_1 = 5

y_1 = 4

x_2 = 0

y_2 = -3

QS = √ ( 0 - 5)^2 + ( -3 - 4)^2

= √ -5^2 + -7^2

= √ 25 + 49

= √ 74

= 8.60

Between Q( 5,4) and R(5 , -3)

x_1 = 5

y_1 = 4

x_2 = 5

y_2 = -3

QR = √ (5 - 5)^2 + ( -3 - 4)^2

= √ 0^2 + (-7)^2

= √ 0 + 49

The sale price of 3 pepper plants after a 20% discount is $12.

To figure out the sale price of 3 pepper plants after a 20% discount, we first calculate 20% of the regular price. The regular price of one pepper plant is $5, so 20% of $5 is $1. Therefore, the sale price of one pepper plant is $5 - $1 = $4. As Wes wants to buy 3 plants, we multiply this sale price by 3, so the total price after discount for 3 plants is $4 * 3 = $12.

So, the sale price of 3 pepper plants after a 20% discount is $12.
