Answer:

angle a = 74 degrees

angle b = 106 degrees

angle c = 106 degrees

angle d = 65 degrees

angle e = 65 degrees

Step-by-step explanation:

Angle a:

the Alternate Interior Angles Theorem makes angle a equal to 74 degrees

Angle b:

First find angle c, and angle b is equal to angle c because angle b and c are Corresponding angles

Angle c:

angle c = 180 degrees - 74 degrees

angle c = 106 degrees

Angle d:

angle d corresponds with 65 degrees, therefore the are the same.

Angle e:

angle d and e are opposite angles, therefore they are the same.

If ∠EFH and ∠HFI are complementary angles,∠EFH = (2x + 2)°  and ∠HFI= (x+1), the measure of x will be 29°.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that, ∠EFH and ∠HFI are complementary angles,∠EFH = (2x + 2)°  and ∠HFI= (x+1),

Complementary angles are those where the sum of the two angles is 90 degrees. In other words, two angles are considered complementary if they combine to form a right angle. The two angles are said to complement one another in this context.

Since ∠EFH and ∠HFI are complementary angles,

∠EFH + ∠HFI = 90

(2x + 2)+ (x+1) =90

3x+3=90

x+1=30

x=29°

Thus, if ∠EFH and ∠HFI are complementary angles,∠EFH = (2x + 2)°  and ∠HFI= (x+1),the measure of x will be 29°.

What do you mean by algebraic expression?

In mathematics, an algebraic expression is an expression composed of integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by exponents that are rational numbers).

Algebraic equations are equations that contain only algebraic expressions.

Algebraic expression is the idea of ​​using letters or alphabets to represent numbers without specifying the actual value. Algebra Basics taught us how to use letters like x, y, and z to represent unknown values. These characters are called variables here.

It is given that Chang pays a monthly fee of $27, and he pays an additional $0.07 per minute of use.

Let m be the additional minutes

Then charge for additional minutes is $0.07m

Now , it is also given that least he has been charged in a month is

$121.71.

⇒ 0.07m + 27 = 121.71

⇒ 0.07m = 121.71 - 27

⇒ 0.07m = 94.71

⇒ m = 94.71/0.07 = 1353

Therefore, 1353 numbers of minutes he has used his phone in a month.

In the tenth week, the runner will run 17.5 miles.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, A runner is training for a marathon.

The first​ week, she runs 4 miles during each training session.

Here a₁ = 4.

Each​ week, she increases her distance by 1.5 miles.

d = 1.5

We know the nth term of an AP is aₙ = a₁ + (n - 1)d.

∴ In tenth week which is a₁₀ the runner will run,

a₁₀ = a₁ + (10 - 1)×1.5

a₁₀ = 4 + 9(1.5).

The statement that best compares the graph of G(x) with the graph of F(x) is the graph of G(x) is the graph of F(x) compressed vertically, flipped over the x-axis, and shifted 7 units to the left.

According to the question,

We have the following information:

F(x) = x² and G(x) = -1/4 (x+7)²

Now, the graph of G(x) will be the graph of F(x) but there will be certain changes in the graph according to its function.

Now, in this function, 7 is added to x then it means that it will shift 7 units to left.

There is a negative sign before the function which says that is flipped over the x-axis.

Now, the factor 1/4 in the multiplication says that it has been compressed.

The correct answer is:  " 4096 x⁶ " .

Step-by-step explanation:

Given:   [(4x)³] ² ;  Simplify.

Method 1)
Note the following multiplication property of exponents:
    ⇒ (aᵇ)ᶜ  = a⁽ᵇ*ᶜ⁾  ;

As such:

   [ [(4x)³] ²  = (4x)⁽²ˣ³⁾ = (4x)⁶ ;

Now; note the following property of exponents:
   (ab)ᶜ  = aᶜ * bᶜ  ;

As such:  (4x)⁶ = 4⁶ * x⁶ ;

Now; we can simplify 4⁶  ;  by using a calculator:
  →  4⁶  = 4096 ;

Or:  4⁶  =  4 * 4 * 4 * 4 * 4 * 4 ;

            =  (4 * 4) * 4 * 4 * 4 * 4 ;

            = 16 * 4 * 4 * 4 * 4 * ) ;

            = (16 * 4) * 4 * 4 * 4 ;

            =  64 * 4 * 4 * 4 ;  

            =   (64 * 4) * 4 * 4 ;

            =   (126 * 4) * 4    

            =  (256) * 4 ;

            =  4096 .
_______

or:   4⁶  = 4 * 4 * 4 * 4 * 4 * 4 ;

             =  (4 * 4) * (4 * 4) * (4 * 4) ;

             = 16 * 16 * 16 ;

             =  (16 * 16) * 16 ;

             = (256) * 16 ,   =  4096.

_______
So:       [(4x)³] ²  =  4⁶  *  x⁶  =  4096 x⁶ ;
_______
Method 2) Given: [(4x)³] ² ;

 (4x)³     =  4x * 4x * 4x ;

 [(4x)³]²  =  (4x * 4x * 4x)²

              = (4x * 4x * 4x) * (4x * 4x * 4x) ;

              =    (4 * 4 * 4 * x * x * x * 4 * 4 * 4 * x * x * x ;

              =   4 * 4 * 4 * 4 * 4 * 4 * x * x * x * x * x * x ;

 ⇒ (4 * 4 * 4 * 4 * 4 * 4)  = 4⁶  = 4096 ; (see Method 1 above).
 ⇒ (x * x *  x * x * x * x)  = x⁶ ;

                      ⇒  [(4x)³] ² =  4⁶ * x⁶ =  4096 x⁶ ;
_______
Method 3)
 [(4x)³] ²  = (4x)⁽²ˣ³⁾  = (4x)⁶ ;

      (4x)⁶ = 4x * 4x * 4x * 4x * 4x * 4x ;

              = 4 * 4 * 4 * 4 * 4 * 4 * x * x * x * x * x * x ;

              = (4 * 4 * 4 * 4 * 4 * 4) * (x * x * x * x * x * x) ;

⇒ (4 * 4 * 4 * 4 * 4 * 4) = 4⁶ = 4096 ; [see Method 1 above].
⇒  (x * x * x * x * x * x)  = x⁶ ;

                      ⇒   [(4x)³] ² =  4⁶ * x⁶ =  4096 x⁶ .

The lengths of the sides of the rectangular field in order to minimize the cost will be length = 6000 feet and width = 4000 feet  .

In the question ,

it is given that ,

the area that farmer need to fence = 24 million square feet

let the length of  field be [tex]=[/tex]"x"   and

let the width  of rectangular field be  [tex]=[/tex]"y"  .

So , the area of the rectangular field = x.y = 24

So , y = 24/x  .

given that the field is divided into half ,

So , the required fencing will be

S = 2x + 3y

Substituting y = 24/x in the equation,

we get ,

S = 2x + 3(24/x)

S = 2 + 72/x

Differentiating the equation "S [tex]=[/tex] 2 [tex]+[/tex] 72/x" with respect to "x" ,

dS/dx = 2 - 72/x²

to minimize the cost of fencing , we equate ds/dx to 0 ,

we get

2 - 72/x² = 0

x² = 36 million feet

x² = 36000000

x = 6000 feet

and y = 24/x = 24million/6000

= 24000000/6000

= 4000 feet

Therefore , The length of the rectangular field is 6000 feet and the width of the rectangular field is 4000 feet .
