Answer: C) [tex]B= 500(1.101)^{12t}[/tex]

Step-by-step explanation:

Given : The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years.

For monthly interest , Rate = [tex]\dfrac{r}{12}[/tex]

Time = 12 t  [ 1 year = 12 months ]

As r = 0.13 , so rate = [tex]\dfrac{0.13}{12}\approx0.010[/tex]

Now, the equation will be :

[tex]B=500 (1+0.101)^{12t}[/tex]

[tex]\Rightarrow\ B= 500(1.101)^{12t}[/tex]

Correct option : C) [tex]B= 500(1.101)^{12t}[/tex]

Answer:

x=37

y=125

Step-by-step explanation:

97+28+x+18=180 (sum of the interior angles of a triangle is 180)

143+x=180

x=180-143

x=37

y+x+18=180 (sum of the angles on a straight line is 180°)

y+37+18=180

y+55=180

y=180-55

y=125

or

y=97+28(exterior angle of a triangle= 2 interior opposite angles)

y= 125

Answer:

∠ D = 110°

Step-by-step explanation:

Assuming the quadrilateral is a parallelogram.

• Consecutive angles sum to 180° , then

∠ B + ∠ C = 180 , that is

5x + 3x + 4 = 180

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22

Then

∠ B = 5x = 5 × 22 = 110°

• Opposite angles are congruent

∠ D = ∠ B = 110°

Answer:

  follow directions. h represents a horizontal shift, + shifts to the right. k represents a vertical shift, + shifts up.

Step-by-step explanation:

Modern math instruction often tends toward giving you a task that is intended to help you discover for yourself particular mathematical relationships. This is one such task.

Here, you're intended to follow the instructions: using the technology provided (a graphing tool at the link) to discover the effect of changing the values of h and k in the function.

__

The first attachment shows plots from my graphing tool for different values of h. The red curve shows h=-2, the blue curve shows h=0, and the green curve shows h=1. If you look for the marked upward zero crossing, you see that it is unshifted for h=0, shifted left 2 units for h=-2, and shifted right 1 unit for h=1.

You are intended to conclude that the value of h represents the amount by which the function is shifted to the right.

__

The second attachment shows plots from my graphing tool for different values of k. As before, the red curve shows k=-2, the blue curve shows k=0, and the green curve shows k=1. Again, the upward zero crossing has been marked to show the effect. For k=-2, the curve is shifted down 2 units; for k=1, it is shifted up 1 unit. There is no shift when k=0.

You are intended to conclude that the value of k represents the amount by which the function is shifted upward.

__

If you do what the problem tells you to do, you can see these effects in real time, watching changes as they occur. You are expected to describe them. Only you know what the "vocabulary from 9/21-922" is.

Additional comment

Math instruction builds on previously seen concepts. This is not a subject in which you can be successful adopting the strategy of "test and forget." You're better off with a strategy of "learn it thoroughly and remember," working as many problems as necessary to keep it fresh in your mind.

Answer:

G. [tex] C = 25(p - 2) + 439 [/tex]

Step-by-step explanation:

Amount paid by customer to fly to California if carrying 2 pieces or less than 2 pieces of luggage for which they won't be charged for = $439

Fee for additional luggage = $25

Fee for additional luggage if an individual carries p luggages = 25(p - 2)

Total amount (C) if p pieces of luggage were carried by a customer travelling = fee for additional p pieces of luggage + $439

The function for this would be:

[tex] C = 25(p - 2) + 439 [/tex]

Answer:

Step-by-step explanation:

Answer:

4x - 9x + 11 = -24

-5x + 11 = - 24

-5x = -24 - 11

-5x = -35

-5x/-5 = -35/-5

x = 7

Answer:

The answer is 7

Step-by-step explanation:

Firstly, you have to subtract 11 from -24, which is -35. Then, add the values with x. Which is -5. -35 divided by -5 equals 7. You can check the answer by doing (4*7)-(9*7)+11=-24

Answer:

Exact volume = 30,000 + 5,000pi cubic mm

Approximate volume = 45,700 cubic mm

========================================================

Explanation:

Break the figure into two pieces.

The top part is a half-cylinder with radius r = 20/2 = 10 mm and height h = 100 mm.

The volume of this half-cylinder is

V = 0.5*(full cylinder volume)

V = 0.5*pi*r^2*h

V = 0.5*pi*10^2*100

V = 5000pi

This is exact in terms of pi.

The lower part is a 20 mm by 100 mm by 15 mm rectangular block. It has volume of length*width*height = 20*100*15 = 30,000 cubic mm.

---------

We'll add the two volumes found earlier to get the overall volume.

The total exact volume is 30,000+5,000pi cubic mm.

To get an approximation, you can use something like pi = 3.14

30000+5000pi = 30000+5000*3.14 = 45,700 cubic mm is the approximate volume when using pi = 3.14

Answer: The salesperson must sell 20 memberships to make the same amount of money under both plans.

Step-by-step explanation:

Let x be the number of memberships.

In first plan,

Weekly salary of $300 plus a commission of $15 for each membership sold.

i.e. Earning (weekly) = 300+15x

In second plan,

The other plan offers no salary but pays $30 commission on each membership sold.

i.e. earning = 30x

According to the question, when [tex]300+15x=30x[/tex]

[tex]\Rightarrow\ 300=30x-15x\\\\\Rightarrow\ 300=15x\\\\\Rightarrow\ x=\dfrac{300}{15}\\\\\Rightarrow\ x=20[/tex]

Hence, the salesperson must sell 20 memberships to make the same amount of money under both plans.

Utilizando el teorema, veremos que la altura de la torre es 7 metros.

El teorema de Tales nos dice que para triangulos similares, la razon entre los catetos debe ser igual.

Esto significa que la razon entre la altura y el largo de la sombra de un objeto debe ser una constante.

Sabemos que Kevin tiene una estatura de 1.75m y proyecta una sombra de 3.5m

El cociente es:

3.5m/1.75m = 2

Es decir, la sombra tiene una longitud de dos veces la altura.

Entonces si la sombra de la torre es de 14m y la altura es h, tendremos:

14m/h = 2

h = 14m/2 = 7m

La altura de la torre es de 7 metros.

D. the product of x and a factor not depending on x

Step-by-step explanation:

The equation for the given expression is:

[tex]x (2y+7z)^{2}[/tex]

According to the expression, there are two factors:

the first factor is x, and

the second factor is [tex](2y+7z)^{2}[/tex]

Since, the second factor do not contain x, therefore it is independent of x.

Hence, the expression for the given equation will be the product of x and a factor not depending on x.

El decimal siempre va a la izquierda.

0.053

Step-by-step explanation:

Proof using Discrimant:

[tex]3 { x}^{2} - 2x + \frac{1}{3} = 0[/tex]

The discrimant is

[tex] \sqrt{ {b}^{2} - 4ac} [/tex]

B is -2, A is 3 and C is 1/3 so we get

[tex] \sqrt{ {2}^{2} - 4( 3)( \frac{1}{3}) } [/tex]

[tex] \sqrt{4 - 4} [/tex]

[tex] \sqrt{0 } = 0[/tex]

Since the discrimant equal zero, there is one real distinct zero.

This zero will also have a multiplicity of 2, so the zero is technically equal to each other.

To get better at solving, let solve for zero.

[tex]3 {x}^{2} - 2x + \frac{1}{3} = 0[/tex]

[tex]3( {x}^{2} - \frac{2}{3} x + \frac{1}{9} )[/tex]

[tex]3( x - \frac{1}{3} )(x - \frac{1}{3} )[/tex]

[tex]3(x - \frac{1}{3} ) {}^{2} = 0[/tex]

[tex]x = \frac{1}{3} [/tex]

That zero is 1/3,1/3

It is an equation because it has an equal sign and it must solve for the variable which is "n".
