Answer:

50°

Step-by-step explanation:

The blue lines form a Right-angled triangle.

*Such triangles have one angle equal to 90°.*

*Property*

Sum of all angles in a triangle = 180°

To find :

Value of x – an angle of the right-angled triangle.

Solution:

==> 90 + 40 + x = 180

==> 130 + x = 180

isolating x

==> x = 180 - 130

==> x = 50°

The perimeter of the rectangle in yards is; 46 1/3 yards

The perimeter of a rectangle is the sum of the lengths of all its sides as follows;

Perimeter of a rectangle = 2(width + length

P = 2(10 1/3 + 12 5/6)

P = 2(31/3 + 77/6)

P = 2(139/6)

P = 46 1/3 yards.

Therefore, the perimeter of the rectangle in yards is 46 1/3 yards

Explanation:

If x+2 is a factor of the other polynomial mentioned, then x = -2 is a root of that polynomial.

This means plugging x = -2 into the cubic expression will have it result in zero.

x^3- kx^2 +3x+7k = y

(-2)^3- k*(-2)^2 +3*(-2)+7k = 0

-8 - 4k - 6 + 7k = 0

3k - 14 = 0

3k = 14

k = 14/3

[tex]{x,y} = {2,-3}[/tex]

Step-by-step explanation:

[tex]x - y = 5 \\\\[2] 3x - 2y = 12[/tex]    <----------- Linear equations given

Graphic Representation of the Equations: PICTURE

[tex]y + x = 5 \\-2y + 3x = 12[/tex]
Solve by Substitution :

// Solve equation [1] for the variable  [tex]x[/tex]

[tex][1] x = y + 5[/tex]

// Plug this in for variable  [tex]x[/tex]  in equation[tex][2][/tex]

[tex][2] 3*(y +5) - 2y = 12 \\ [2] y = -3[/tex]

// Solve equation [tex][2][/tex] for the variable [tex]y[/tex]

[tex][2] y = - 3[/tex]

// By now we know this much :

[tex]x = y+5 \\ y = -3[/tex]

[tex]\\ \tt\hookrightarrow a_n=ar^{n-1}[/tex]

[tex]\\ \tt\hookrightarrow a_n=32(3/2)^{n-1}[/tex]

Answer:

[tex]a_n=32 \cdot \left(\dfrac32 \right)^{n-1}[/tex]

Step-by-step explanation:

The difference between each term in the sequence is not the same, therefore the sequence is a geometric sequence.

Geometric sequence formula:  [tex]a_n=a r^{n-1}[/tex]

where [tex]a[/tex] is the start term and [tex]r[/tex] is the common ratio

Given [tex]a = 32[/tex]

To calculate [tex]r[/tex], divide one term by its previous term:

[tex]\implies r=\dfrac{a_4}{a_3}=\dfrac{108}{72}=\dfrac32[/tex]

Therefore, [tex]a_n=32 \cdot \left(\dfrac32 \right)^{n-1}[/tex]

The number 6.38×10⁻⁵ written in ordinary form is 1/638000.

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in scientific form in a compact manner.

Given, A number in scientific form as 6.38×10⁻⁵.

Now, We know an exponent must be written as a positive value.

Therefore,

6.38×10⁻⁵.

= 1/ 6.38×10⁵.

Now, The ordinary form of the number is when we write without the exponent.

So,

1/ 6.38×10⁵ is,

= 1/638000.

x>8 and x<2 are the two possible inequalities of |x - 5| > 3

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Let x be the number

|x - 5| > 3

Now solve for x.

Suppose x - 5 is positive.  Then

x - 5 > 3

x > 8

Suppose x - 5 is negative.  Then |x - 5| = -(x - 5) = 5 - x

5-x>3

5-3>x

2>x

x<2

Hence, x>8 and x<2 are the two possible inequalities of |x - 5| > 3
