if you invest $10,000 at 10% interest account compounded monthly, how much money you will have in 20 years?

Answers

Answer:

$73280.74

Step-by-step explanation:

We will use the compound interest formula to find the answer

A = P (1 + r/n)^(nt)

Where A is the total amount of money, P is the principal investment amount (how much you put in initially), R is the interest rate, N is the number of times interest is applied per period and T is the number of time periods elapsed.

$10,000 would be the principal investment amount

10% would be the interest rate

12 would be the number of times interest is applied per period (since it is paid monthly)

and 20 would be the number of time periods (as it's the number of years)

A = 10000(1+0.1/12)^(12*20)

A = 10000(7.3280736)

A = 73280.74

Step-by-step explanation:

The line rises 1 unit for each 1 unit it goes to the right. The slope is ...

  m = rise/run = 1/1 = 1

The line intersects the y-axis at y=6, so the y-intercept is ...

  b = 6

Answer: Compute the probability of drawing two aces from a standard deck of 52 cards. Round your answer to four decimal places. Answer:

Answers

It’s 110 because you add two 52

The 0.0588 = 5.88% probability of drawing two clubs from a standard deck of 52 cards.

0.0498 = 4.98% probability of drawing two faces from a standard deck of 52 cards.

0.0045 = 0.45% probability of drawing two aces from a standard deck of 52 cards

What is the probability?

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

We know standard deck has 52 cards.

And 13 cards are for clubs.

(a).

The probability,

= number of favorable outcomes / number of outcomes

= 13 x 12 / 52 x 51

= 0.0588

0.0588 = 5.88% probability of drawing two clubs from a standard deck of 52 cards.

(b). 12 faces in a deck.

The probability,

= number of favorable outcomes / number of outcomes

= 12 x 11 / 52 x 51

= 0.04977

= 0.0498

0.0498 = 4.98% probability of drawing two faces from a standard deck of 52 cards.

(c). There are 4 aces in the deck.

The probability,

= number of favorable outcomes / number of outcomes

= 4 x 3 / 52 x 51

= 0.0045

0.0045 = 0.45% probability of drawing two aces from a standard deck of 52 cards.

Therefore, the probabilities are 0.0588, 0.0498 and 0.0045.

For the function y=x+1 what is the range if the domain is 0,1,2

Answers

Step-by-step explanation:

the domain is the interval or set of the valid values of x.

the range is the interval or set of the valid values of y.

the domain here is 0, 1 and 2.

to find the range we just have to try all 3 values of x and check the results :

x = 0

y = 0 + 1 = 1

x = 1

y = 1 + 1 = 2

x = 2

y = 2 + 1 = 3

The responses are;

First Part: A repeated-measures design is appropriate for; A researcher would like to study the effect of advanced training on sales figures.

Second Part: An independent-measures design is one in which; Different participants perform in each condition.

Reasons:

First Part:

investigation that makes use of the same group or sample set, but taking

measurement of the members of the set under two different conditions or

at two different times.

Therefore;

A repeated-measures design would be appropriate in the situation where; A researcher would like to study the effect of advanced training on sales figures.

Second Part:

An independent-measures design is one that compares the properties

within two samples, such that the information in the population is not

required. It is a between-groups design, such that different participants

are used for the different conditions of the independent variable.

Therefore;

The option that is an independent-measures design is; Different participants perform in each condition.

Hi if anyone could help I would very much appreciate it thx ,Enter values to write the function that matches the graph shown.

Answers

Answer:

v(x) = (2x+8)(-2x+-2)

Step-by-step explanation:

Graph the equation and the functions will be the same.

Answer:

See below

Step-by-step explanation:

We can observe that:

The x- intercepts are - 4 and  - 1The y- intercept is - 16Graph opens down, the leading coefficient is negative

According to observations, the function is:

f(x) = a(x - (-4))(x - (-1)) = a(x + 4)(x + 1)

Find the value of a, using the y - intercept:

- 16 = a(0 + 4)(0 + 1)- 16 = 4aa = -16/4a = - 4

The function is:

f(x) = - 4(x + 4)(x + 1)

In standard form it is:

f(x) = - 4(x² + 5x + 4) = - 4x² - 20x - 16

Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs k(x)=(300+10x)(5-0.2x)

Answers

The value of [tex]x[/tex] associated to the extreme value of the quadratic equation [tex]k(x) = (300+10\cdot x)\cdot (5-0.2\cdot x)[/tex]. The extreme value is [tex]k\left(-\frac{5}{2} \right) = \frac{3025}{2}[/tex].

First, we need to expand the polynomial as follows:

[tex]k(x) = (300+10\cdot x)\cdot (5-0.2\cdot x)[/tex]

[tex]k(x) = 300\cdot (5-0.2\cdot x)+10\cdot x\cdot (5-0.2\cdot x)[/tex]

[tex]k(x) = 1500-60\cdot x +50\cdot x -2\cdot x^{2}[/tex]

[tex]k(x) = -2\cdot x^{2}-10\cdot x +1500[/tex]

[tex]-2\cdot x^{2}-10\cdot x +[1500-k(x)] = 0[/tex]

By the quadratic formula, we know that a value of [tex]x[/tex] pass through the axis of symmetry of the parabola if and only if the discriminant is zero:

[tex]-100-4\cdot (-2)\cdot [1500-k(x)] = 0[/tex]

And the value of [tex]x[/tex] is:

[tex]x = -\frac{(-10)}{2\cdot (-2)}[/tex]

[tex]x = -\frac{5}{2}[/tex]

And the extreme value is:

[tex]k\left(-\frac{5}{2} \right) = -2\cdot \left(-\frac{5}{2} \right)^{2}-10\cdot \left(-\frac{5}{2} \right) + 1500[/tex]

[tex]k\left(-\frac{5}{2} \right) = \frac{3025}{2}[/tex]

The value of [tex]x[/tex] associated to the extreme value of the quadratic equation [tex]k(x) = (300+10\cdot x)\cdot (5-0.2\cdot x)[/tex]. The extreme value is [tex]k\left(-\frac{5}{2} \right) = \frac{3025}{2}[/tex].

In the diagram, AABC = AWRS. What is the
perimeter of AWRS?

10 units
11 units
12 units
13 units

Answers

Answer:

12 units

Step-by-step explanation:

Both triangles have the same perimeter, so we can figure out 1 and have the answer for both.

The legs of triangle AABC are 3 and 4, so we can use the Pythagorean Theorem to figure out the other side.

3² + 4² =

9 + 16 = 25

√25 = 5

To find the perimeter, just add the three sides.

3 + 4 + 5 = 12 units

The perimeter of the triangle WRS is 12 units, Option C is correct.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

As we observe the two triangles ABC and WRS

The given triangles are similar triangles.

So if we find the perimeter of any triangle then it will be equal to other triangle.

From the triangle ABC

AB =3 units

BC =4 units

By pythagoras theorem let us find AC

AB²+BC²=AC²

3²+4²=AC²

9+16=AC²
25=AC²

Take square root on both sides

AC=5 units

To find the perimeter we need to add the three sides.

3 + 4 + 5 = 12 units

Hence, the perimeter of the triangle WRS is 12 units, Option C is correct.
