Answer:

P = 8x + 4

Step-by-step explanation:

P = 2(l + w)

P = 2(5 + 4x - 3)

P = 2(4x + 2)

P = 8x + 4

Answer:

D.) x2 + (y + 1)2 = 1

Step-by-step explanation:

No explanation needed just need to say something here.

Answer:

x2 + (y + 1)2 = 1

Step-by-step explanation:

Answer:

y=2x-1

Step-by-step explanation:

1. 7-3/4-2=2 so the slope would be 2

2. substitute (4,7) in y=mx+b which gets b=-1

3. so this means that the equation is y=2x-1

Answer: [tex]2514.28\ cm^3[/tex]

Step-by-step explanation:

Given

The height of the cylinder is [tex]h=8\ cm[/tex]

Circumference of the base is [tex]20\pi \ cm[/tex]

suppose 'r' is the radius of the cylinder

[tex]\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm[/tex]

The volume of a cylinder is [tex]V=\pi r^2h[/tex]

[tex]\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3[/tex]

Answer:√40 to be the square root of 40, and can investigate between which two whole numbers it lies. The number 40 lies between 36 and 49 hence √40 lies between 6 and 7.

Between 6 and 7

Step-by-step explanation:

40 lies between 36 and 49

find square root of each (6 and 7)

Answer:

P.y = [tex]4^{x}[/tex]

Step-by-step explanation:

From the given question, since Jesse sends the email to 4 people and the 4 people rebroadcast it to another 4 persons each. And this process continues for a required or given round x, then this is an example of an exponential function.

Thus, the number of emails sent for a given round can be expressed as;

                    y = [tex]4^{x}[/tex]

Therefore, the appropriate answer is y = [tex]4^{x}[/tex].

So that for four rounds (x = 4), the number of emails sent can be determined as;

y = [tex]4^{x}[/tex]

  = [tex]4^{4}[/tex]

y = 256

Answer: y=4^x

Answer:

The answer would be -3.

Step-by-step explanation:

If you follow PEMDAS, the first set of parenthesis, (-4)(2), would equal -8. The next set of parenthesis, (10/2), would equal 5. Adding -8 and 5 together gives you -3.

Answer:

8

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Calculating the Least Common Multiple :

3.1    Find the Least Common Multiple

     The left denominator is :       9

     The right denominator is :       18

       Number of times each prime factor

       appears in the factorization of:

Prime

Factor   Left

Denominator   Right

Denominator   L.C.M = Max

{Left,Right}

3 2 2 2

2 0 1 1

Product of all

Prime Factors  9 18 18

     Least Common Multiple:

     18

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 2

  Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      4 • 2

  ——————————————————  =   —————

        L.C.M              18  

  R. Mult. • R. Num.       x

  ——————————————————  =   ——

        L.C.M             18

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4 • 2 - (x)     8 - x

———————————  =  —————

    18           18  

Equation at the end of step

:

 8 - x

 —————  = 0

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 8-x

 ——— • 18 = 0 • 18

 18

Now, on the left hand side, the  18  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  8-x  = 0

Solving a Single Variable Equation:

4.2      Solve  :    -x+8 = 0

Subtract  8  from both sides of the equation :

                     -x = -8

Multiply both sides of the equation by (-1) :  x = 8

One solution was found :

x = 8
