Which exponential function is graphed here.

A) y= 5x

B) y= 5e^x

C) y= 5^x+1

D) y=5^x+1

C. 700 units.

The formula for the surface area of a rectangular prism is: 2 ((Width × Length) + (Height × Length) + (Height × Width))

(14 × 12) + (7 × 12) + (7 × 14)

168 + 84 + 98 = 350

Now do 350 × 2 = 700

700 units squared.

Answer:

Step-by-step explanation:

12)

we are told that ∠ABD = 61°

then we also know that ∠ADB = 61° b/c there are the equal legs of an isosceles triangle.

and we know by inspection that the ΔBCD is identical to ΔABD so it also has 61° angles so

∠ABC = 61 + 61 =122°

Answer:

La población de bacterias después de tres horas es de [tex]2^{14}[/tex] bacterias.

Step-by-step explanation:

En este enunciado observamos un caso de progresión geométrica, en donde la población de bacterias se duplica cada treinta minutos, es decir:

[tex]\frac{p(n\cdot\Delta t)}{p(0)} = 2^{n}[/tex] (1)

Donde:

[tex]\Delta t[/tex] - Intervalo de tiempo requerido para el incremento geométrico de la población, en minutos.

[tex]n[/tex] - Número de períodos para incremento geométrico, sin unidad.

Sabemos que la población inicial de bacterias es 256 y que 3 horas son 6 veces 30 minutos. Entonces, tenemos la siguiente razón:

[tex]\frac{p(6\cdot \Delta t)}{p(0)} = 2^{6}[/tex] (2)

Si sabemos que [tex]p(0) = 256[/tex], entonces [tex]p(6\cdot \Delta t)[/tex] es:

[tex]p(6\cdot \Delta t) = 2^{6}\cdot p(0)[/tex]

[tex]p(6\cdot \Delta t) = 2^{6}\cdot (256)[/tex]

[tex]p(6\cdot \Delta t) = 2^{6}\cdot 2^{8}[/tex]

[tex]p(6\cdot \Delta t) = 2^{14}[/tex]

La población de bacterias después de tres horas es de [tex]2^{14}[/tex] bacterias.

Answer:

The difference in the interest that the account will have earned at the end of 10 years is of:

D. $3.01.

The amount of interest earned, in compound interest, after t years, is given by:

[tex]I(t) = P\left(1 + \frac{r}{n}\right)^{nt} - P[/tex]

In which the variables are listed as follows:

In the context of this problem, these parameters are given as follows:

P = 250, r = 0.016, n = 12, t = 10.

Hence the interest earned by account 1 is:

[tex]I(10) = 250\left(1 + \frac{0.016}{12}\right)^{12 \times 10} - 250 = 43.35[/tex]

For simple interest, the amount of interest earned is:

I(t) = Prt.

Hence:

I(10) = 250 x 0.016 x 10 = 40.

Hence the difference is:

43.35 - 40 = $3.35.

Which is closest to option D.

Step-by-step explanation:

STEP 1:

Equation at the end of step 1

 (22x2 -  36x) +  32  = 0

STEP 2:

STEP 3: Pulling out like terms

3.1     Pull out like factors :

  4x2 - 36x + 32  =   4 • (x2 - 9x + 8)

Trying to factor by splitting the middle term

3.2     Factoring  x2 - 9x + 8

The first term is,  x2  its coefficient is  1 .

The middle term is,  -9x  its coefficient is  -9 .

The last term, "the constant", is  +8

Step-1 : Multiply the coefficient of the first term by the constant   1 • 8 = 8

Step-2 : Find two factors of  8  whose sum equals the coefficient of the middle term, which is   -9 .

     -8    +    -1    =    -9    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -8  and  -1

                    x2 - 8x - 1x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-8)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-8)

Step-5 : Add up the four terms of step 4 :

                   (x-1)  •  (x-8)

            Which is the desired factorization

Equation at the end of step

 4 • (x - 1) • (x - 8)  = 0

Theory - Roots of a product

4.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Equations which are never true:

4.2      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.3      Solve  :    x-1 = 0

Add  1  to both sides of the equation :

                     x = 1

Solving a Single Variable Equation:

4.4      Solve  :    x-8 = 0

Add  8  to both sides of the equation :

                     x = 8

Supplement : Solving Quadratic Equation Directly

Solving    x2-9x+8  = 0   directly

Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula

Parabola, Finding the Vertex:

5.1      Find the Vertex of   y = x2-9x+8

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 1 , is positive (greater than zero).

For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   4.5000  

Plugging into the parabola formula   4.5000  for  x  we can calculate the  y -coordinate :

 y = 1.0 * 4.50 * 4.50 - 9.0 * 4.50 + 8.0

or   y = -12.250

Parabola, Graphing Vertex and X-Intercepts :

Root plot for :  y = x2-9x+8

Axis of Symmetry (dashed)  {x}={ 4.50}

Vertex at  {x,y} = { 4.50,-12.25}

x -Intercepts (Roots) :

Root 1 at  {x,y} = { 1.00, 0.00}

Root 2 at  {x,y} = { 8.00, 0.00}

Solve Quadratic Equation by Completing The Square

5.2     Solving   x2-9x+8 = 0 by Completing The Square .

Subtract  8  from both side of the equation :

  x2-9x = -8

Now the clever bit: Take the coefficient of  x , which is  9 , divide by two, giving  9/2 , and finally square it giving  81/4

Add  81/4  to both sides of the equation :

 On the right hand side we have :

  -8  +  81/4    or,  (-8/1)+(81/4)

 The common denominator of the two fractions is  4   Adding  (-32/4)+(81/4)  gives  49/4

 So adding to both sides we finally get :

  x2-9x+(81/4) = 49/4

Adding  81/4  has completed the left hand side into a perfect square :

  x2-9x+(81/4)  =

  (x-(9/2)) • (x-(9/2))  =

 (x-(9/2))2

Things which are equal to the same thing are also equal to one another. Since

  x2-9x+(81/4) = 49/4 and

  x2-9x+(81/4) = (x-(9/2))2

then, according to the law of transitivity,

  (x-(9/2))2 = 49/4

We'll refer to this Equation as  Eq. #5.2.1  

The Square Root Principle says that When two things are equal, their square roots are equal.

Note that the square root of

  (x-(9/2))2   is

  (x-(9/2))2/2 =

 (x-(9/2))1 =

  x-(9/2)

Now, applying the Square Root Principle to  Eq. #5.2.1  we get:

  x-(9/2) = √ 49/4

Add  9/2  to both sides to obtain:

  x = 9/2 + √ 49/4

Since a square root has two values, one positive and the other negative

  x2 - 9x + 8 = 0

  has two solutions:

 x = 9/2 + √ 49/4

  or

 x = 9/2 - √ 49/4

Note that  √ 49/4 can be written as

 √ 49  / √ 4   which is 7 / 2

Solve Quadratic Equation using the Quadratic Formula

5.3     Solving    x2-9x+8 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     1

                     B   =    -9

                     C   =   8

Accordingly,  B2  -  4AC   =

                    81 - 32 =

                    49

Applying the quadratic formula :

              9 ± √ 49

  x  =    —————

                   2

Can  √ 49 be simplified ?

Yes!   The prime factorization of  49   is

  7•7

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 49   =  √ 7•7   =

               ±  7 • √ 1   =

               ±  7

So now we are looking at:

          x  =  ( 9 ± 7) / 2

Two real solutions:

x =(9+√49)/2=(9+7)/2= 8.000

or:

x =(9-√49)/2=(9-7)/2= 1.000

Two solutions were found :

x = 8

x = 1

We can write the the area of the circle as 110.25π square centimeter.

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -

V = ∫∫F(x, y) dx dy

Given is a circle whose diameter is 21 cm​.

It is asked to find the area of a circle whose diameter is 21 cm​.

It is given that the diameter of the circle is -

d = 21 cm

r = d/2 = 21/2

r = 10.5 cm

We know that the area of the circle as -

Area = πr²

Area = π x 10.5 x 10.5

Area = 110.25π

So, it can be concluded that the area of the circle is 110.25π square centimeter.

Therefore, we can write the the area of the circle as 110.25π square centimeter.
