$2322.2 more the account be worth after 9 years by calculating interest compounded quarterly versus calculating simple interest.

Given that, principal = $1700, rate of interest = 2.7% and time period = 9 years.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.

Here, simple interest = (1700×2.7×9)/100

= 41310/100

= $413.10

Amount = Principal + Simple interest

= 1700+413.10

= $2113.1

Compound interest:

[tex]Amount=P(1+\frac{R}{100} )^{nt}[/tex]

[tex]=1700(1+\frac{2.7}{100} )^{4\times9}[/tex]

[tex]=1700(1.027)^{36}[/tex]

= 1700×2.609

= $4435.3

Now, 4435.3-2113.1=$2322.2

Therefore, $2322.2 more the account be worth after 9 years by calculating interest compounded quarterly versus calculating simple interest.

Answer:

a. -1 + (-3)

b. -9 + 5

Step-by-step explanation:

the sum of two numbers = -4

a.

two addends have the same sign

Since the sum is negative, then both addends must be negative.

Answer: -1 + (-3) =

b.

two addends have different signs

One addend is positive, and one addend is negative. Since the sum is negative, then the addend with the greater absolute value must be negative.

3x - 2 (2.3x + 2.5)  = -1.6x-5 are equivalent expressions while 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3 are not equivalent expressions

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s)

Given: 3x - 2 (2.3x + 2.5) = -1.6x -5 and 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3

For 3x - 2 (2.3x + 2.5):

First, clear the parenthesis by using -2 to multiply what's in the parenthesis. Then add/subtract like terms:    

3x - 2 (2.3x + 2.5) =  3x-4.6x- 5 = -1.6x-5          

For 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3:

First, clear the parenthesis by using -3 to multiply what's in the parenthesis. Then add/subtract like terms:  

5 - 3 (-1.6x - 2.1) = 5 + 4.8x + 6.3  = 4.8x + 11.3

Since 3x - 2 (2.3x + 2.5) is equal to  -1.6x-5 and  5 - 3 (-1.6x - 2.1) is not equal to 4.8x - 1.3.

Therefore, 3x - 2 (2.3x + 2.5)  = -1.6x-5 are equivalent expressions and 5 - 3 (-1.6x - 2.1) = 4.8x - 1.3 are not equivalent expressions

What is linear polynomial equation?

Any polynomial written as the equation p(x) = ax + b, with a and b being real numbers and a 0, is referred to as a linear polynomial. The largest exponent of the variable in a linear polynomial, or one, is known as the degree of the variable.

If n elements are given and x element is subtracted from the n elements, hence the remaining element is y,  then expression can be expressed by n- x = y.

We have,

             (9x - 10)

             (4x + 5)          

Initially Presley has (9x - 10) bracelets and she sells (4x + 5), hence we have to calculate the remaining bracelets.

Therefore,

                         (9x - 10) - (4x + 5)      

By simplifying the above equation we get,

= 9x - 10 - 4x + 5

= 5x -5

x = 5 / 5

∴ x = 1

Hence, the Presley have 1 bracelets left.

The highest value you would still hold the stock is $23.97

From the question, the given parameters about the distribution are

Mean value of the set of data = $26.94

Standard deviation value of the set of data = $3.54

Proportion = Highest 20%

This means that the p value is

p = 20%

Express as decimal

p = 0.2

At a p value of 0.2, the z-score is

z = -0.84

The z-score of the data value is calculated using the following formula

z = (x - mean value)/standard deviation

Substitute the given parameters in the above equation

-0.84 = (x - 26.94)/3.54

Cross multiply in the above equation

So, we have

x - 26.94 = -0.84 * 3.54

Evaluate the products

x - 26.94 = -2.97

Add 26.94 to both sides of the equation

So, we have the following representation

x = 26.94 -2.97

Evaluate the difference

x = 23.97

Hence, the highest value is 23.97

The factor of the difference of two squares (x + 2)² - (y - 2)² is (x + y)(x - y + 4).

If for any two squares say a² and b², then their difference a² - b² = (a + b)(a - b).

Given the two squares (x + 2)² and (y - 2)²

then their difference will yeild the factors derived as follows;

(x + 2)² - (y - 2)² = [(x + 2) + (y - 2)][(x + 2) - (y - 2)]

open brackets

(x + 2)² - (y - 2)² = (x + 2 + y - 2)(x + 2 - y + 2)

collect like terms

(x + 2)² - (y - 2)² = (x + y + 2 - 2)(x - y + 2+ 2)

so

(x + 2)² - (y - 2)² = (x + y)(x - y + 4)

Thus, by application of the rule of difference of two squares, we have the factors of (x + 2)² - (y - 2)² to be (x + y 2 - 2) and (x - y + 2+ 2).

The greatest number of cans each stack can have is 10.

What is Greatest Common Divisor (GCD)?

The number that divides two or more numbers most precisely by itself is said to be the greatest common divisor (GCD) of those numbers. It is also defined as the highest common factor (HCF).

If a and b are two numbers then the greatest common divisor of both numbers is denoted by GCD(a, b).

Given, Total number of cola cans = 150

            Total number of fruit juice cans = 260

According to the question condition, we need to find GCD (150,260)

Now, the prime factorization of 150 and 260 are:

150= 2 x 3 x 5 x 5

260 = 2 x 2 x 5 x  13

So, common factor = 2 x 5 = 10

Then, GCD (150,260) = 10

Hence, the greatest number of cans in each stack can have 10.

The graph of the linear equation for question 12 can be seen in the image at the end of the answer.

If we have a linear equation with a slope m and a point (h, k=, the point-slope form of that linear equation is:

y = m*(x - h) + k

Here the slope is m = -7/4 and the point is (2, -6)

Then the linear equation is:

y = (-7/4)*(x - 2) - 6

To graph the linear equation we need two points on it, and we already know one, so we need to find the other.

To do so we can evaluate in some value of x.

If we use x = -2 we will get:

y = (-7/4)*(-2 - 2) - 6

y = (-7/4)*(-4) - 6

y = 7 - 6 = 1

So we also have the point (-2, 1)

Now we just need to graph the two given points and connect them with a line.

What is parabola and zeroes of parabola?

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

The equation of parabola can be expressed in two different ways, such as the standard form and the vertex form. The standard form of parabola equation is expressed as follows:

f(x) = y= ax2 + bx + c

To find zeroes of parabola

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

Given equation is

f(x) = [tex]x^{2} +6x+5[/tex]

a = 1, b = 6, c = 5

x = -6 ±[tex]\sqrt{36-4(5)}[/tex]/2

x = -6 ±[tex]\sqrt{16} /2[/tex]

x = -6 ± 4 /2

The pairs of events, A and B, that are disjoint include option A and B.

It should be noted that disjoint events simony means the events that are mutually exclusive as they can't occur at the same time.

For option A, because a person can be either male or female but not both, events A and B are disjoint.

For B, because the person already earns more than $100,000, events A and B are not disjoint.

For C, because the sum of two dice cannot be three when one die is three, events A and B are disjoint.

You want the value of f(2) for the graphed function.

The value of the function f(a) is the y-coordinate of the point that has 'a' as its x-coordinate.

Finding the function value requires you locate x=a on the horizontal axis. Where the graph crosses that vertical line, the y-coordinate is the function value.

Here, the vertical line x=2 meets the function graph at the dot with coordinates (2, 3). The y-value there is 3, so ...

  f(2) = 3

Answer:  [D]:  " 3 " ;  [that is; f(2) = 3 ].
____
We are asked to:

Evaluate the given function for f(2) ; within the given image.

By examination of the graph, we can verify that the graph is, in fact, a function—by using the vertical line test.
  We find that no value for x shares more than one y-value; which means that the graph is a function.

Note that for a function:   f(x) = y .

Note:  f(2)  =  the "[ y - coordinate/corresponding value for y ]" ;

Then the fraction of the students taking the test exceeded your score will be given as,

z = (625 - 550) / 85

z = 75 / 85

z = 0.8824

Then the fraction is given as,
