Bill Jensen deposits $8500 with Bank of America in an investment paying 5% compounded semiannually. Find the interest in 6 years

Answers

Amount deposited = $8500

Rate = 5%

time for interest = 6years

Compounded semiannually

The formula for semiannually is

[tex]A=P(1+\frac{r}{100n})^{nt}[/tex]

From the given information

P = $8500

r = 5

t = 6

Since the investment was compounded semiannually then

n = 2

Substitute the values into the formula

This gives

[tex]A=8500(1+\frac{5}{100\times2})^{6\times2}[/tex]

Solve for A

The table represents a linear function.What is the slope of the function?y08-2.04х-4-2-112-10-14-22-26O 2O 5

Answers

Answer

Option B is correct.

The slope of this function = -4

Explanation

For a linear function, the slope of the line can be obtained when the coordinates of two points on the line or the values of the linear function (y) at different values of x are known. If the two points are described as (x₁, y₁) and (x₂, y₂), the slope is given as

[tex]Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1}[/tex]

Using the two extreme points, (x₁, y₁) and (x₂, y₂) are (-4, -2) and (2, -26).

x₁ = -4

y₁ = -2

x₂ = 2

y₂ = -26

[tex]\text{Slope = }\frac{-26-(-2)}{2-(-4)}=\frac{-26+2}{2+4}=\frac{-24}{6}=-4[/tex]

Let d and s be the cost of a double and single- occupancy room, respectively. Since a double-occupancy room cost $20 more than a single room, we can write

[tex]d=s+20\ldots(A)[/tex]

On the other hand, we know that 15 double-rooms and 26 single-rooms give $3088, then, we can write

[tex]15d+26s=3088\ldots(B)[/tex]

Solving by substitution method.

In order to solve the above system, we can substitute equation (A) into equation (B) and get

[tex]15(s+20)+26s=3088[/tex]

By distributing the number 15 into the parentheses, we have

[tex]15s+300+26s=3088[/tex]

By collecting similar terms, it yields,

[tex]41s+300=3088[/tex]

Now, by substracting 300 to both sides, we obtain

[tex]41s=2788[/tex]

then, s is given by

[tex]s=\frac{2788}{41}=68[/tex]

In order to find d, we can substitute the above result into equation (A) and get

[tex]\begin{gathered} d=68+20 \\ d=88 \end{gathered}[/tex]

Therefore, the answer is:

[tex]\begin{gathered} \text{ double occupancy room costs: \$88} \\ \text{ single occupancy room costs: \$68} \end{gathered}[/tex]

Charlene and Gary want to make perfume. In order to get the right balance of ingredients for their tastes they bought 2ounces of rose oil at $4.36 per ounce, 5 ounces of ginger essence for $2.15 per ounce, and 4 ounces of black currant essence for $2.27 per ounce. Determine the cost per ounce of the perfume.

Answers

First, lets calculate how much the expended in the perfume:

[tex]2\times(4.36)+5\times(2.15)_{}+4\times(2.27)=28.55[/tex]

So, for 11 ounces of perfume, they need $28.55, so the minimum that the perfume need to cost per ounce is:

[tex]\frac{28.55}{11}=2.5954\cong2.6[/tex]

So, about $2.6 per ounce of perfume.

Answers

By solving the equations, we can conclude that the two numbers are 4 and 6.

What are equations?An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values. As in 3x + 5 = 15, for example. There are many different types of equations, including linear, quadratic, cubic, and others. The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, the two numbers are:

Let the 2nd number be 'x'.Then, the 1st number will be '4x - 20'.

The equation will be:

4x - 20 + x = 10

Now, solve this equation for 'x' as follows:

4x - 20 + x = 105x = 10 + 205x = 30x = 6

Now, 4x - 20:

4(6) - 2024 - 204

Therefore, by solving the equations, we can conclude that the two numbers are 4 and 6.

In the question ;

it is given that

the inequality -3(2x-5)<5(2-x)

on solving this inequality further , we get

-3(2x-5)<5(2-x)

-6x+15<10-5x

which is option (c) .

Further solving

Subtracting 15 from both the sides of the inequality  , we get

-6x + 15 -15 < 10 -5x -15

-6x < -5 -5x

-6x +5x < -5

-x < -5

So first of all let's take:

Then we get:

The next step would be operate with the inequalities and the equation so we end up having only the term y at the left side of each:

[tex]\begin{gathered} \text{Min}z=1.5x+2y \\ 1.5x+2y=\text{Min}z \\ 2y=\text{Min}z-1.5x \\ y=\frac{\text{Min}z}{2}-0.75x \end{gathered}[/tex][tex]\begin{gathered} x+y\ge300 \\ y\ge300-x \end{gathered}[/tex][tex]\begin{gathered} 2x+y\ge400 \\ y\ge400-2x \end{gathered}[/tex][tex]\begin{gathered} 2x+5y\leq750 \\ y\leq150-\frac{2}{5}x \end{gathered}[/tex]

So now we have the following inequalities and equality:

[tex]\begin{gathered} y=\frac{\text{Min}z}{2}-0.75x \\ y\ge300-x \\ y\ge400-2x \\ y\leq150-\frac{2}{5}x \end{gathered}[/tex]

If we take the three inequalities and replace their symbols by "=' we'll have three equations of a line:

[tex]\begin{gathered} y=300-x \\ y=400-2x \\ y=150-\frac{2}{5}x \end{gathered}[/tex]

The following step is graphing these three lines and delimitating a zone in the grid that meets the inequalities:

Where the blue area is under the graph of y=150-(2/5)x which means that it meets:

[tex]y\leq150-\frac{2}{5}x[/tex]

And it is also above the x-axis, y=400-2x and y=300-x which means that it also meets:

[tex]\begin{gathered} x\ge0 \\ y\ge0 \\ y\ge400-2x \\ y\ge300-x \end{gathered}[/tex]

All of this means that the values of x and y that give us the correct minimum of z are given by the coordinates of a point inside the blue area. The next thing to do is take the four possible values for Min(z) and use them to graph four lines using this equation:

[tex]y=\frac{\text{Min}z}{2}-0.75x[/tex]

Then we have four equations of a line:

[tex]\begin{gathered} y=\frac{450}{2}-0.75x \\ y=\frac{780}{2}-0.75x \\ y=\frac{647}{2}-0.75x \\ y=\frac{354}{2}-0.75x \end{gathered}[/tex]

The line that has more points inside the blue area is the one made with the closest value to Min(z). Then we have the following graph:

As you can see there are two lines that have points inside the blue area. These are:

[tex]\begin{gathered} y=-\frac{3}{4}x+\frac{450}{2} \\ y=-\frac{3}{4}x+\frac{354}{2} \end{gathered}[/tex]

That where made using:

[tex]\begin{gathered} \text{Min }z=450 \\ \text{Min }z=354 \end{gathered}[/tex]

Taking a closer look you can see that the part of the orange line inside the blue area is larger than that of the red line. Then the value used to make the orange line would be a better aproximation for the Min z. The orange line is -(3/4)x+450/2 which means that the answer to this problem is the first option, 450.

It is a quadrilateral, meaning the two lengths are equal. Like wise the two widths are equal.

length PQ = length SR = 2

Length QR = length PS = 4

Scale factor = 3/4

Scale factor = corresponding side of new image/ corresponding side of original image

PQRS = original image, P'Q'R'S' = new image

3/4 = P'Q'/PQ

3/4 = P'Q'/2

P'Q' = 2(3/4) = 6/4 = 3/2

Since P'Q' = S'R'

S'R' = 3/2

3/4 = Q'R'/QR

3/4 = Q'R'/4

Q'R' = 3/4 (4) = 12/4 = 3

Since Q'R' = P'S

P (5, 5), Q (3, 5), R (3, 1), S (5, 1)

PQRS to P'Q'R'S' = 3/4(

P' = 3/4 (5, 5) = (15/4, 15/4)

Q' = 3/4 (3, 5) = (9/4, 15/4)

Answers

Let A be the event "person under 18" and B be the event "employed part-time". So, we need to find the following probability

[tex]P(A\text{ or B) =P(A}\cup B)[/tex]

which is given by

[tex]P(A\text{ or B) =P(A}\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

Since the total number od people in the table is equal to n=4089, we have that

[tex]P(A)=\frac{28+174+395}{4089}=\frac{597}{4089}[/tex]

and

[tex]P(B)=\frac{174+194+71+179+173}{4089}=\frac{791}{{4089}}[/tex]

and

[tex]P(A\cap B)=\frac{174}{4089}[/tex]

we have that

[tex]P(A\text{ or B) =}\frac{597}{4089}+\frac{791}{{4089}}-\frac{174}{4089}[/tex]

which gives

[tex]P(A\text{ or B) =}\frac{597+791-174}{4089}=\frac{1214}{4089}=0.29689[/tex]

Therefore, the answer the searched probability is: 0.296

A local road has a grade of 5%. The grade of a road is its slope expressed as a percent. What is the slope? What is the rise? What is the run?

Answers

[tex]\begin{gathered} a)\text{ }\frac{1}{20} \\ b)\text{ Rise:1 ft, Run: 20ft} \end{gathered}[/tex]

a) Since the grade is given by the slope, and the grade has a 5%.

We can rewrite it as a fraction, like this:

[tex]\frac{5}{100}=\frac{1}{20}[/tex]

Note that we have simplified this to 1/20 by dividing the numerator and the denominator (bottom number) by 5

So, the slope is:

[tex]\frac{1}{20}[/tex]

b) The "rise" is the difference between two coordinates on the y-axis and the "run" is the subtraction between two coordinates on the x-axis. Let's remember the slope formula and the Cartesian plane:

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{1}{20}[/tex]

So the "rise" for this grade is 1 foot and the run is 20 feet.

3) Hence, the answers are:

[tex]\begin{gathered} a)\text{ }\frac{1}{20} \\ b)\text{ }Rise\colon\text{ }1\text{ Run: 20} \end{gathered}[/tex]

Given

[tex]-16t^2+v_0t+h_0[/tex]

initial velocity = 60 feet per second

initial height = 95 feet

Find

Maximum height attained by the ball

Explanation

we have given

[tex]\begin{gathered} h(t)=-16t^2+60t+95 \\ h^{\prime}(t)=-32t+60 \end{gathered}[/tex]

put h'(t) = 0

[tex]\begin{gathered} -32t+60=0 \\ -32t=-60 \\ t=\frac{60}{32}=1.875sec \end{gathered}[/tex]

to find the maximum height find the value of h(1.875)

[tex]\begin{gathered} h(1.875)=-16(1.875)^2+60(1.875)+95 \\ h(1.875)=-56.25+112.5+95 \\ h(1.875)=-56.25+207.5 \\ h(1.875)=151.25 \end{gathered}[/tex]

Final Answer

Therefore , the maximum height attained by the ball is 151.25 feet
