Answer:

An equation for the nth term of the arithmetic sequence.

[tex]a_n=3n-1[/tex]

Step-by-step explanation:

Given the sequence

2,5,8,11,...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

here

computing the differences of all the adjacent terms

Using the nth term formula

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting a₁ = 2, d = 3

[tex]a_n=2+\left(n-1\right)3[/tex]

     [tex]=2+3n-3[/tex]

     [tex]=3n-1[/tex]

Thus, an equation for the nth term of the arithmetic sequence.

[tex]a_n=3n-1[/tex]

(–5)(–6) = 30

NEW EQUATION: 5z – 4 + 15z + 30

COMBINE your LIKE TERMS

Complete question :

You can spend up to $35 on a shopping trip.

a. You want to buy a shirt that costs $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt.

b. You notice that the shirt is on sale for %30 off. How does this change the inequality?

c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.

Answer:

x ≤ 21

x ≤ 25.2

Yes

Step-by-step explanation:

Cost of shirt = $14

Total Amount to spend ≤ $35

After shirt purchase :

Let amount left = x

x + 14 ≤ 35

x ≤ 35 - 14

x ≤ $21

B.) discount on shirt sale = 30%

(100% - 30%) of $14 = 0.7 * $14 = $9.8

x ≤ 35 - 9.8

x ≤ 25.2

C.)

Cost of Jean = 23

25.2 > 23

Hence, there is enough money

Answer:

208

Step-by-step explanation:

169/65%=260= the original number

260 x 80% = 208

Answer:

208 is 80% of that number

Step-by-step explanation:

to find the number, take 65/100 (or 65%), and set it equal to 169/x (because x is the number that 169 is 65% of, so we need to find x)=> 65/100=169/x

Next, cross multiply to get 16900=65x

Divide both sides of the equation by 65 to get 260=x, which means that 260 is the mystery number that the question speaks of. Then, to get 80% of 260, set 80/100 equal to x/260=> 80/100=x/260

cross multiply to get 20800=100x

divide both sides by 100 to get 208

Therefore, the answer is 208

Answer:

= − 7 /1 1  in fraction form

Step-by-step explanation:

STEP 1: Multiply by 1

1 + 1 0 + 2 5 = 1 8

+ 1 0 + 2 5 = 1 8                                                                                                                               STEP 2: Combine like terms

+ 1 0 + 2 5 = 1 8

1 1 + 2 5 = 1 8                                                                                                                       STEP 3: Subtract  2 5   from both sides of the equation

11x+25=18

1 1 + 2 5 − 2 5 = 1 8 − 2 5

STEP 4: Simplify  by subtracting the numbers

1 1 + 2 5 − 2 5 = 1 8 − 2 5

11x+25−25=18−25                                                                                                   1 1 = 1 8 − 2 5                                                                                                                                   1 1 =  -7

STEP 5: Divide both sides of the equation by the same term                                                     1 1 = − 7                                                                                                                         11x/ 11x = −7/ 1 1 (set up as a fraction)                                                                       STEP 6: Cancel terms that are in both the numerator and denominator

=  − 7 /1 1                                                                                                                      SOLUTION

=  − 7 /1 1

Answer:

Frequency = 8 Hz ; Period = 0.125 s

Step-by-step explanation:

The amplitude of a wave is simply regarded as the maximum displacement experienced by a vibrating both from its equlibrum position.

The Displacement marked A in th picture is tbe Amplitude of the wave

The wavelength refers to the a complete cycle moved by a wave, that is the distance from a crest to another (maximum upward Displacement) or a trough to another (maximum downward Displacement).

2.)

Given that :

Velocity (V) of wave = 20 m/s

Wavelength (λ) = 2.5 m

The frequency (f) of the wave ;

f = v /λ

f = (20 m/s) ÷ 2.5m

f = 8 Hz

The period T of the wave :

T = 1 /f

T = 1 / 8

T = 0.125 seconds

This is the correct solution for your question

Answer:

The given equation will have two roots as +5i and -5i

Step-by-step explanation:

Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function

The given equation is [tex]x^2+25 =0[/tex]

This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots

[tex]x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\[/tex]

[tex]x = i\sqrt{25}[/tex]

x = ± 5i

It will be false to say that -5i will be the only complex root to this equation.

The given equation will have +5i and -5i as its roots.

Lets verify

x = +5i

[tex](5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0[/tex]

x = -5i

[tex](-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0[/tex]

Step-by-step explanation:

f(2)=18-2=16
