Answer:

[tex]T_n = 2n -3[/tex]

Step-by-step explanation:

Given

[tex]S_n = n^2- 2n[/tex]

[tex]T_n = S_n - S_{n-1[/tex]

Required

Find [tex]T_n[/tex]

[tex]S_n = n^2- 2n[/tex]

Calculate [tex]S_{n-1[/tex]

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

[tex]S_{n-1} = n^2-2n+1- 2n+2[/tex]

[tex]S_{n-1} = n^2-2n- 2n+1+2[/tex]

[tex]S_{n-1} = n^2-4n+3[/tex]

[tex]T_n = S_n - S_{n-1[/tex] becomes

[tex]T_n = n^2 - 2n - (n^2 - 4n +3)[/tex]

[tex]T_n = n^2 - 2n - n^2 + 4n -3[/tex]

[tex]T_n = n^2 - n^2- 2n + 4n -3[/tex]

[tex]T_n = 2n -3[/tex]

Answer:

the answer is D

Step-by-step explanation:

55-23=32

Answer:

16

Step-by-step explanation:

shorter piece measures x  

longer piece measures x +23

Together they measure 55 ft

x + (x+23)  =  55

2x + 23 =  55

      -23 = -23

Answer:

The answer is y = 2.

Step-by-step explanation:

1) Add 5 to both sides.

[tex]6y = 7 + 5[/tex]

2) Simplify 7 + 5 to 12.

[tex]6y = 12[/tex]

3) Divide both sides by 6.

[tex]y = \frac{12}{6} [/tex]

4) Simplify 12/6 to 2.

[tex]y = 2[/tex]

Thus, the answer is y = 2.

The value of y in 6y-5=7 is 2.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

6y-5=7

Now, solving for y

Add 5 both side

6y-5 + 5=7 +5

6y= 12

Now, divide both side by 6

6y/6 = 12/6

y= 2

Hence, the value of y is 2.

( -3, -5)

Step-by-step explanation:

6x + 13 = 2x + 1

6x -2x = 1-13

4x = -12

x = -12/4 = -3

y = 6x + 13

y = 6(-3) +13 = -18+13 = -5

(x, y) = (-3,-5)

Answer: (x-4) is not a factor of the given polynomial.

===================================================

Explanation:

Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).

In this case, we have k = 4 and we can find that:

p(x) = 2x^4-9x^3-20x^2+147x-180

p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180

p(4) = 24

The result we get is not zero, so that means (x-4) is not a factor of p(x).

Answer:

The right solution is "-8.25".

Step-by-step explanation:

The given values are:

Sampled people,

n = 150

Null and alternative hypotheses will be:

[tex]H_0:p=0.53[/tex]

[tex]Ha:p\neq 0.53[/tex]

The z-statistics will be:

⇒ [tex]z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }[/tex]

On substituting the values, we get

⇒    [tex]=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }[/tex]

⇒    [tex]=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }[/tex]

⇒    [tex]=\frac{-0.33}{0.04}[/tex]

⇒    [tex]=-8.25[/tex]

Answer:

x=29

Step-by-step explanation:

The sum of angles in a triangle is 180deg.

We know this is a right triangle, so the third angle is 90deg, leaving us with 90deg for the other two.

(2x-2) + (x+5) = 90

3x + 3 = 90

3x = 87

x = 29

Answer:

11 shots

Step-by-step explanation:

60% of 18 = 10.8

10.8 rounded = 11

Why we did this:

Owen made 60% of the shots he made, and he made 18 shots in total. Therefore, we would take 60% of 18.

The answer we get is 10.8, but we can't have a part of a shot. That wouldn't make sense. Therefore, we have to round up to 11 shots.
