The quadratic equation that has the roots 3 + i and 3 - i is x² - 6x + 10 = 0.

The general form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are constants.

The roots of the quadratic equation are the values of x that make the equation equal to zero.

Therefore, if a quadratic equation has the roots 3 + i and 3 - i, it can be written in the factored form as (x - (3 + i))(x - (3 - i)) = 0. Expanding this product yields x² - (3 + i + 3 - i)x + (3 + i)(3 - i) = 0.

Simplifying this expression further results in the quadratic equation x² - 6x + 10 = 0.

The quadratic equation that has the roots 3 + i and 3 - i is x² - 6x + 10 = 0.

The calculated age of the sample is 2865 years. Since this is less than 5,000 years, the scientist's hypothesis that the tree bark is over 5,000 years old is incorrect.

To determine if the scientist's hypothesis is correct, we can use the concept of half-life and the given information.

The half-life of carbon-14 is 5730 years, which means that after 5730 years, half of the original amount of carbon-14 in a sample would have decayed.

In this case, the fossilized tree bark is thought to be over 5,000 years old. If the sample contains 75% of the original amount of carbon-14, it means that 25% of the carbon-14 has decayed.

Let's calculate the number of half-lives that have passed:

(100% - 75%) / 50% = 0.25 / 0.5 = 0.5

So, 0.5 half-lives have passed.

Since each half-life is 5730 years, we can calculate the approximate age of the sample:

0.5 half-lives × 5730 years per half-life = 2865 years

The calculated age of the sample is 2865 years. Since this is less than 5,000 years, the scientist's hypothesis that the tree bark is over 5,000 years old is incorrect.

To discover the finest range of applications that may in shape in the truck, we want to calculate the volume of the truck and divide it by using the quantity of every cube-formed bundle.

The quantity of the truck is given with the aid of the method:

Volume = Length x Width x Height

Volume = 8 ft x 61 ft x 71 ft

Volume = 34,808 cubic toes

The volume of every cube-shaped bundle is given with the aid of the method:

Volume = Side [tex]Length^3[/tex]

Volume = 1 [tex]ft^3[/tex]

Number of packages = Volume of truck / Volume of each package

Number of packages = 34,808 ft^3 / 1 ft^3

Number of packages = 34,808

Thus, the greatest number of packages that can fit in the truck is 34,808.

Volume of the part of the truck being filled = Number of packages x Volume of each package

Volume of the part of the truck being filled = 34,808 x 1 ft^3

Volume of the part of the truck being filled = 34,808 ft^3

Step-by-step explanation:

Given quadratic number pattern:

To find the equation for the nth term, we can use the general form of a quadratic equation:

[tex]\boxed{T_n=an^2 + bn + c}[/tex]

where n is the position of the term.

Let's substitute the values of T₁, T₂ and T₄ into the quadratic equation: to create three equations:

[tex]\begin{aligned}T_1=a(1)^2+b(1)+c&=-1\\a+b+c&=-1\end{aligned}[/tex]

[tex]\begin{aligned}T_2=a(2)^2+b(2)+c&=5\\4a+2b+c&=5\end{aligned}[/tex]

[tex]\begin{aligned}T_4=a(4)^2+b(4)+c&=35\\16a+4b+c&=35\end{aligned}[/tex]

Rearrange the first equation to isolate c:

[tex]c=-a-b-1[/tex]

Substitute this into the second and third equations:

[tex]\begin{aligned}4a+2b+(-a-b-1)&=5\\3a+b&=6\end{ailgned}[/tex]

[tex]\begin{aligned}16a+4b+(-a-b-1)&=35\\15a+3b&=36\end{ailgned}[/tex]

Solve the equations simultaneously by rearranged the first equation to isolate b and substituting this into the second equation and solving for a:

[tex]b=-3a+6[/tex]

[tex]\begin{aligned}15a+3(-3a+6)&=36 \\15a-9a+18&=36\\6a&=18\\a&=3 \end{aligned}[/tex]

Substitute the found value of a into the equation for b and solve for b:

[tex]\begin{aligned}b&=-3a+6\\&=-3(3)+6\\&=-9+6\\&=-3\end{aligned}[/tex]

Finally, substitute the found values of a and b into the equation for c and solve for c:

[tex]\begin{aligned}c&=-a-b-1\\&=-3-(-3)-1\\&=-3+3-1\\&=-1\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\boxed{T_n=3n^2-3n-1}[/tex]

The value of x is the 3rd term. Therefore, to find the value of x, substitute n = 3 into the equation for the nth term:

[tex]\begin{aligned}T_3&=3(3)^2-3(3)-1\\&=3(9)-3(3)-1\\&=27-9-1\\&=18-1\\&=17\end{aligned}[/tex]

Therefore, the value of x is 17.

[tex]\hrulefill[/tex]

Given quadratic number pattern:

To find the equation for the nth term, we can use the general form of a quadratic equation:

[tex]\boxed{T_n=an^2 + bn + c}[/tex]

where n is the position of the term.

Let's substitute the values of T₁, T₂ and T₄ into the quadratic equation: to create three equations:

[tex]\begin{aligned}T_4=a(4)^2+b(4)+c&=37\\16a+4b+c&=37\end{aligned}[/tex]

Rearrange the first equation to isolate c:

[tex]c=-a-b+4[/tex]

Substitute this into the second and third equations:

[tex]\begin{aligned}4a+2b+(-a-b+4)&=9\\3a+b&=5\end{ailgned}[/tex]

[tex]\begin{aligned}16a+4b+(-a-b+4)&=37\\15a+3b&=33\end{ailgned}[/tex]

Solve the equations simultaneously by rearranged the first equation to isolate b and substituting this into the second equation and solving for a:

[tex]b=-3a+5[/tex]

[tex]\begin{aligned}15a+3(-3a+5)&=33 \\15a-9a+15&=33\\6a&=18\\a&=3 \end{aligned}[/tex]

Substitute the found value of a into the equation for b and solve for b:

[tex]\begin{aligned}b&=-3a+5\\&=-3(3)+5\\&=-9+5\\&=-4\end{aligned}[/tex]

Finally, substitute the found values of a and b into the equation for c and solve for c:

[tex]\begin{aligned}c&=-a-b+4\\&=-3-(-4)+4\\&=-3+4+4\\&=5\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\boxed{T_n=3n^2-4n+5}[/tex]

The value of x is the 3rd term. Therefore, to find the value of x, substitute n = 3 into the equation for the nth term:

[tex]\begin{aligned}T_3&=3(3)^2-4(3)+5\\&=3(9)-4(3)+5\\&=27-12+5\\&=15+5\\&=20\end{aligned}[/tex]

The area of the shaded region is (133π/9) square feet.

Given that the radius (r) is 4 ft, the area of the entire circle is:

A = π(4)² = 16π ft²

To find the area of the sector, we need to calculate the fraction of the circle that the central angle represents.

The fraction is determined by dividing the measure of the central angle (110°) by the total angle in a circle (360°).

Fraction of the circle represented by the sector = 110° / 360° = 11/36

To find the area of the sector, we multiply the fraction by the area of the entire circle:

Area of the sector = (11/36) × (16π)

= (11π/9) ft²

Finally, to find the area of the shaded region, we subtract the area of the sector from the area of the entire circle:

Area of shaded region = Area of entire circle - Area of sector

Area of shaded region = 16π - (11π/9)

Area = Length × Width

= (3n + 2) × n

= 3n^2 + 2n

Therefore, the area of the rectangle, in terms of n, is 3n^2 + 2n.

Answer:

  4

Step-by-step explanation:

You want the product of terms (n+1)/n for integers n from 1 to 3.

When there are only 3 terms, we can write out the product:

  (1 +1)/1 × (2 +1)/2 × (3 +1)/3 = 2 × 3/2 × 4/3 = 4

The product is 4.

Additional comment

You will notice the first term has a denominator of 1. In each pair of terms, the numerator of a term cancels the denominator of the next term. This means the product of k terms will always be (k+1). For 3 terms, the product is 3+1 = 4.

To determine how the surface area of a rectangular prism changes when all dimensions are quadrupled, we need to compare the original surface area to the new surface area.

The original surface area of the rectangular prism is given by:

SA_original = 2lw + 2lh + 2wh

where l, w, and h represent the length, width, and height of the prism, respectively.

In this case, the dimensions of the original box are:

Length (l) = 3 ft

Width (w) = 6 ft

Height (h) = 5 ft

Substituting these values into the formula, we have:

SA_original = 2(3)(6) + 2(3)(5) + 2(6)(5)

            = 36 + 30 + 60

            = 126 square feet

Now, if we quadruple all the dimensions of the box, the new dimensions would be:

Length (l_new) = 4(3) = 12 ft

Width (w_new) = 4(6) = 24 ft

Height (h_new) = 4(5) = 20 ft

The new surface area of the enlarged box is given by:

SA_new = 2(l_new)(w_new) + 2(l_new)(h_new) + 2(w_new)(h_new)

       = 2(12)(24) + 2(12)(20) + 2(24)(20)

       = 576 + 480 + 960

       = 2016 square feet

Comparing the original surface area (SA_original = 126 sq ft) to the new surface area (SA_new = 2016 sq ft), we can see that SA_new is 16 times greater than SA_original.

Therefore, the correct answer is:

1. The new surface area would be 16 times the original surface area.

Using trigonometric identities sin(x)/[1 - cos(x)] - sin(x)cos(x)/[1 + cos(x)] = csc (x)(1 + cos² (x)),

Trigonometric identities are equations that contain trigonometric ratios.

To verify the trigonometric identity

sin(x)/[1 - cos(x)] - sin(x)cos(x)/[1 + cos(x)] = csc (x)(1 + cos² (x)), we need to show that Left Hand Side, L.H.S equals Right Hand Side R.H.S. We proceed as follows.

L.H.S = sin(x)/[1 - cos(x)] - sin(x)cos(x)/[1 + cos(x)]

Taking the L.C.M, we have that

{sin(x)[1 + cos(x)] - sin(x)cos(x)[1 - cos(x)]}/[1 - cos(x)][1 + cos(x)]

Expanding the brackets, we have that

{sin(x) + sin(x)cos(x)] - sin(x)cos(x) + sin(x)cos²(x)]}/[1 - cos(x)][1 + cos(x)]

Simplifying, we have that

= {sin(x) + 0 + sin(x)cos²(x)]}/[1 - cos²(x)] Since ([1 - cos(x)][1 + cos(x)] = [1 - cos²(x)]

= {sin(x) + sin(x)cos²(x)]}/sin²(x)  [since sin²(x) = 1 - cos²(x)]

Factorizing out sinx in the equation, we have that

= {sin(x)(1 + cos²(x)]}/sin²(x)

= (1 + cos²(x)]}/sin(x)

= cosec(x)(1 + cos²(x)]}  (since cosec(x) = 1/sin(x))

= R.H.S

Since L.H.S = R.H.S, we have that

sin(x)/[1 - cos(x)] - sin(x)cos(x)/[1 + cos(x)] = csc (x)(1 + cos² (x))
