Answer:

The lum sum that must be deposited today is $12,506.25 to have a future value of $25,000 in 9 years if the funds carn 8%, compounded annually.

Step-by-step explanation:

We are given:

Future value (A)=$25,000

Rate r =8% (0.08%)

Time t = 9

Compounded Annually n =1

We need to find:

Principal Amount (P) = ?

The formula used will be:

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

Putting values and finding Principal Amount (P)

[tex]A=P(1+\frac{r}{n})^{nt}\\25000=P(1+\frac{0.08}{1})^{9*1} \\25000=P(1+0.08)^{9} \\25000=P(1.08)^{9} \\25000=P(1+0.08)^{9} \\25000=P(1.9990)\\P=\frac{25000}{1.9990}\\\mathbf{P=12506.25 }[/tex]

So, The lum sum that must be deposited today is $12,506.25 to have a future value of $25,000 in 9 years if the funds carn 8%, compounded annually.

Step-by-step explanation:

Answer:

The line has a slope of zero which means the line is a horizontal line.

Step-by-step explanation:

Given that:

The two points are (-3,2) and (4,2)

Slope of a line is given by the formula,

[tex]m = \frac{Rise}{Run} = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Here,

[tex]x_{1}=-3,\ y_{1}=2\\x_{2}=4,\ y_{2}=2[/tex]

Putting these values in formula;

[tex]m=\frac{2-2}{4-(-3)} \\m = \frac{0}{4+3}\\m = \frac{0}{7} = 0[/tex]

Hence,

The line has a slope of zero which means the line is a horizontal line.

Answer: Peak Point offers the better deal.

Step-by-step explanation:

To find which has the best price, we need to know the cost for one day at each mountain. To do this, we would divide the cost of each pack by the number of days it pays for, so

$275.60/5 days

and $174.75/3 days.

Peak Point costs $55.12 per day while Grand mountain costs $58.25 for each day. This shows that Peak Point clearly has the better deal, costing $3.13 less for every day included in the pack.

Mixed number: 6 1/100

Improper Fraction: 601/100

Step-by-step explanation:

Hope this helps!

Answer:

Mixed number: [tex]6\frac{1}{100}[/tex]

Improper fraction: [tex]\frac{601}{100}[/tex]

Step-by-step explanation:

A mixed number is a fraction that contains an integer and fraction part. An improper fraction is a fraction where the numerator is larger than the denominator.

[tex]6.01[/tex] can be written in the from [tex]\frac{601}{100}[/tex]. This is an improper fraction since the numerator is greater than the denominator.

The mixed number is [tex]6\frac{1}{100}[/tex] since [tex]100[/tex] goes into [tex]601[/tex] six full times with [tex]1[/tex] as the remainder.

Hope this helps :)

Answer:

(2).

Step-by-step explanation:

We have the expression:

[tex]\displaystye{\ln(\displaystyle{\frac{\sqrt{e}}{y^3})}[/tex]

First, we can use the difference property of logarithms:

[tex]\ln(x/y)=\ln(x)-\ln(y)[/tex]

Hence, this is equivalent to:

[tex]=\ln(\sqrt{e})-\ln(y^3)[/tex]

We can rewrite the left as:

[tex]=\ln(e^\frac{1}{2})-\ln(y^3)[/tex]

Now, we can use the power property:

[tex]\ln(a^b)=b\ln(a)[/tex]

Essentially, we move the exponent to the front.

Hence, this yields:

[tex]=\frac{1}{2}\ln(e)-3\ln(y)[/tex]

The natural log of e is simply 1. Hence:

[tex]=\frac{1}{2}-3\ln(y)[/tex]

Combine fractions:

[tex]\displaystyle{=\frac{1}{2}-\frac{6\ln(y)}{2} \\ =\frac{1-6\ln(y)}{2}}[/tex]

Hence, our answer is (2).

Answer:

x = 46

Step-by-step explanation:

This is basic trigonometry, so we can apply this procedure...

- The total sum of all angles in a triangle is 180 (no angle should be more than 180, this is the limit) and we only need to know just one angle labeled as x, this is represented as:

130 + 96 + x = 180

x = 130 + 96 - 180

- Now we just need to obtain x:

x = 130 + 96 - 180

x = 226 - 180

x = 46

Answer:

Step-by-step explanation:

[tex]y=-x^2+4x+5\quad \implies\quad a=-1\,,\ b=4\,,\ c=5\\\\h=\dfrac{-b}{2a}=\dfrac{-4}{2(-1)}=2\\\\k=c-\dfrac{b^2}{4a}=5-\dfrac{4^2}{4(-1)}=5-\dfrac{16}{-4}=5+4=9[/tex]

Or by completing the square:

[tex]y=-x^2+4x+5\\\\y=-(x^2-4x)+5\\\\y=-(\underline{x^2-2\cdot x\cdot 2+2^2}-2^2)+5\\\\y=-\left((x-2)^2-4\right)+5\\\\y=-(x-2)^2+4+5\\\\y=-(x-2)^2+9\quad\implies\quad h=2\,,\ k=9[/tex]

Answer:

Matching the population trend to a contributing factor:

Contributing Factors                                                 Population Trends

government-sponsored family control programs    Low birth rate

agricultural economies                                              increase in food supply

medical advancements                                             low death rate

Industrial Revolution                                                 high birth rate

Step-by-step explanation:

a) Contributing factors are some negative or positive factors that influence or cause a single event or chain of events that result to the incident.

b) Defining population trends:

1) High birth rate: the industrial revolution triggered high birth rate, following increased food supply and medical advancements.

2) Low death rate: medical advancements brought about low death rate as better healthcare is provided to the sick.

3) Increase in food supply: large-scale agricultural economies ensured increasing food production and supply.

4) Low birth rate: when governments started sponsoring family control programs, the resulting effect was low birth rate.

Answer: 7 3/4

Step-by-step explanation:

From the question, we are informed that Steven has 10 1/4 pages of homework and that he finishes 2 1/2 pages every ten minutes.

The number of pages that Steven will have left after 10 minutes will be:

= 10 1/4 - 2 1/2

= 7 3/4

He'll have 7 3/4 pages left

Step-by-step explanation:

44 = 2 * h * 11

44 = 22 * h

divide 22 on both sides, and you get the answer

2 = h

A = 2h(B + b)

Disregard my first reply.

Here is the math work.

44 = 2h(2 + 9)

44 = 4h + 18h

44 = h(4 + 18)

44/(4 + 18) = h

44/22 = h

Divide top and bottom by 11.

4/2 = h

2 = h

Done!

Answer:

when dividing fractions folow these steps:

first, you need to switch the denom and num of the second fraction:

3/4 ÷ 1/3---> 3/4 ÷ 3/1

Next you just switch the sign of the negative to a multiplication sign and multiply:

3/4 ÷ 3/1---> 3/4 x 3/1

3/4 x 3/1 -----> 9/4

9/4, 2 1/4 - these are your answers. Either are correct

Answer:

[tex]\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=\frac{27}{4x^9y^8}[/tex]

Step-by-step explanation:

Given the expression

[tex]\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}[/tex]

solving the expression

[tex]\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=4\cdot \:\frac{\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}[/tex]

             [tex]=4\:\frac{27x^3y^{12}}{16x^{12}y^{20}}[/tex]

              [tex]=4\cdot \frac{3^3}{2^4x^9y^8}[/tex]

The multiply fractions are defined as

[tex]\:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]

so the expression becomes

                [tex]=\frac{3^3\cdot \:4}{2^4x^9y^8}[/tex]

                [tex]=\frac{3^3\cdot \:2^2}{2^4x^9y^8}[/tex]

                [tex]=\frac{3^3}{2^2x^9y^8}[/tex]

Refining

                 [tex]=\frac{27}{4x^9y^8}[/tex]

Therefore,

[tex]\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=\frac{27}{4x^9y^8}[/tex]

Answer: B) No, every x-value does not have exactly one y-value

Explanation:

We have the input x = 3 map to the outputs y = 2 and y = 8 at the same time. A function is only possible if any given x value goes to exactly one y value.

Put another way, if x repeats itself, then we don't have a function. This assumes we don't repeat the same y value when we repeat the x value.

Answer: y = -1*x^2 - 4

Step-by-step explanation:

A generic quadratic equation is written as:

y = a*x^2 + b*x + c

we need to find the values of a, b, and c

We have the table:

x     y = f(x)

-4     -20

-3       -13

-2        -8

-1         -5

0         -4

1          -5

In the table we can see two things:

y(0) = a*0^2 + b*0 + c = c = -4

Then we know that:

y(x) = a*x^2 + b*x - 4

Now we only need to find a and b.

We also can see that we have symmetry around the point x = 0, this means that x = 0 is the vertex of the quadratic equation, and for a general case the vertex is at:

x = -b/2a

and this is equal to zero:

-b/2a = 0

then we must have b = 0.

So for now, the equation is:

y = a*x^2 -4

Now we can just replace the values of any of the points to find the value of a, for example we can use the point (1, -5)

this means that:

y = -5 = a*1^2 - 4

    -5 = a - 4

    -5 + 4 = a

        -1 = a

Then the quadratic equation is:

y = -1*x^2 - 4
