Step-by-step explanation:

21.

1, 2, 4, 8, 16, 31, ... , ....

by using the formula, we can find :

T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =

(2401 - 2058 + 1127 - 126 +24) / 24 =

1368/ 24 = 57

T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =

(4096-3072+1472-144+24)/24 =

2376/ 24 = 99

Resposta:

Explicação:

[tex] \sin 20^\circ = \dfrac{1,83~m}{x} [/tex]

[tex] x = \dfrac{1,83~m}{\sin 20^\circ} [/tex]

Answer:

add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate

Answer:

147

Step-by-step explanation:

If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Step-by-step explanation:

Given:

To find h(g(f(x))) first find g(f(x)), substitute x with f(x):

Since g(x) = x², the value of g(2x + 5) is:

Now, the next step:

Answer:

Step-by-step explanation:

a) Number = x

Multiply it by 3 = 3*x = 3x

Now add 4 to it: 3x + 4

Equation:  

3x +4 = 22

b)

3x + 4 = 22

Subtract 4 from both sides

3x + 4 -4 = 22 - 4

        3x = 18

Divide both sides by 3

3x/3 = 18/3

x = 6

Answer:

Below in bold.

Step-by-step explanation:

The equation is

3x + 4 = 22

3x = 22 - 4 = 18

x = 18/3

x = 6.

Answer:

7 quaters and 19 dimes

Step-by-step explanation:

Let say x the numbers of quaters,

2*x+5 the numbers of dimes

In cents,: 25*x+10*(2x+5)=365

25x+20x+50=365

45x=365-50

45x=315

x=7

Number of quaters: 7

Number of dimes: 2*7+5=19

Proof:

7*25+10*19=365

Answer:

the awnser of this question is 3,5,8

Answer:

number is 3

Step-by-step explanation:

let the number be n then the product of 3 and the number is 3n , so

16 = 7 + 3n ( subtract 7 from both sides )

9 = 3n ( divide both sides by 3 )

3 = n

That is the number is 3

Answer:

I Kg = 1000 g

3 Kg = 3000 Kg

Step-by-step explanation:

Kg - Hg - Dag - g

1 Kg - 10 Hg - 100 Dag - 1000 g

So, 1 Kg = 1000 g

3 Kg = 3(1000)g = 3000 g

Answer:

[tex]x_{1} =\frac{-17- \sqrt{129}}{2}, x_{2} =\frac{-17+ \sqrt{129}}{2} [/tex]

Step-by-step explanation:

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} = \frac{5}{2} [/tex]

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} = \frac{5}{2} [/tex]

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} - \frac{5}{2} = 0[/tex]

[tex] \frac{2(x + 2 {)}^{2} + 2(x + 3) \times (x - 3) - 5(x + 3) \times (x + 2) }{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] \frac{2(x + 2 {)}^{2} + 2( {x}^{2} - 9) + ( - 15x - 15) \times (x + 2) }{2(x + 3) \times (x + 2)} = 0 [/tex]

[tex] \frac{2( {x}^{2} + 4x + 4) - 3 {x}^{2} - 48 - 25x}{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] \frac{2 {x}^{2} + 8x + 8 - 3 {x}^{2} - 48 - 25x }{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] \frac{ - {x}^{2} - 17x - 40 }{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] {x}^{2} + 17x + 40 = 0[/tex]

[tex]x = \frac{ - 17± \sqrt{ {17}^{2} - 4 \times 1 \times 40 } }{2 \times 1} [/tex]

[tex]x = \frac{ - 17± \sqrt{289 - 160} }{2} [/tex]

[tex]x = \frac{ - 17± \sqrt{129} }{2} [/tex]

[tex]x_{1} =\frac{-17- \sqrt{129}}{2}, x_{2} =\frac{-17+ \sqrt{129}}{2} [/tex]

Answer:

This equation is in y=mx + b form. Just plug in the point to get N, which is also B.

Whatever is in f(x) is your x. So x = 9; This means...

4 = 2/3(9) + n

Solving for n gets you -2.

Now we plug in -3 and also substitute N now that we solved for it.

f(-3) = 2/3(-3) - 2

f(-3) = -4

Answer:

The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.

Step-by-step explanation:

To check whether the sequence proves that shape I is similar to shape IV, check whether the given sequence of transformations maps shape I onto shape IV.

1. Dilate shape I by a scale factor of 2.

2. Then, reflect the dilated shape across the x-axis.

3. Finally, translate the reflected shape 1 unit left.
