Step-by-step explanation:

An individual saves $5000 in a bank account at the beginning of each year for 10 years.
No further savings or withdrawals are made from the account. Determine the total amount saved if the annual interest rate is 8% compounded:
(a) annually;
(b) semi-annually.

Answers

Answer:

a) Amount saved if the interest is compounded annually is $5832

b) Amount saved if the interest is compounded semi-annually is $5849.5

Step-by-step explanation:

Principal Amount P = 5000

Time t = 10 years

Annual interest i = 8% = 0.08

We need to find amount saved if interest is compounded a) annually b) semi-annually

a) Amount saved if the interest is compounded annually

If interest compounded annually, n= 1

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

Putting values:

[tex]A=P(1+\frac{r}{n})^{nt} \\A=5000(1+\frac{0.08}{1})^{1*2}\\A=5000(1+0.08)^2\\A=5000(1.08)^2\\A=5000(1.1664)\\A=5832[/tex]

So, Amount saved if the interest is compounded annually is $5832

b) Amount saved if the interest is compounded semi-annually

If interest compounded semi-annually, n= 2

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

Putting values:

[tex]A=P(1+\frac{r}{n})^{nt} \\A=5000(1+\frac{0.08}{2})^{2*2}\\A=5000(1+0.04)^4\\A=5000(1.04)^4\\A=5000(1.1699)\\A=5849.5[/tex]

So, Amount saved if the interest is compounded semi-annually is $5849.5

(a). When compounded annually, the amount will be [tex]\$ 10,794.6[/tex]

(b). When compounded semi-annually, the amount will be [tex]\$ 10,955.6[/tex]

Compound interest:

It is given that, an individual saves $5000 in a bank account at the beginning of each year for 10 years.

[tex]Principal(P)=5,000, t=10 years, rate(r)=8\%[/tex]

As we know that,

               [tex]Amount=P(1+\frac{r}{100} )^{t} \\\\Amount=5,000(1+\frac{8}{100})^{10} \\\\Amount=5,000*(\frac{108}{100})^{10}\\\\Amount=\$ 10,794.6[/tex]

When interest is compounded semi-annually;

[tex]r=8/2=4\%, t=10*2=20[/tex]

             [tex]Amount=5,000(1+\frac{4}{100})^{20} \\\\Amount=5,000*(\frac{104}{100})^{20}\\\\Amount=\$ 10,955.6[/tex]

Answers

Answer:

Mick can run farther in less time if that's the question

Step-by-step explanation:

Mick's speed is faster.

What is speed?

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Carlos can run 5 miles in 45 minutes.

45 minutes = 45/60 = 0.75 hours

Speed.

= 5/0.75

= 6.66 miles per hour.

Kelly can run 10 miles in 80 minutes.

80 minutes = 1.33 hours

Speed.

= 10/1.33

= 7.5 miles per hour.

Mick can run 30 miles in 170 minutes

170 minutes = 2.8 hours

Speed.

= 30/2.8

= 10.7 miles per hour

Thus,

Mick's speed is faster.

Emma and her children went into a restaurant where they sell hotdogs for $4 each and drinks for $1.50 each. Emma has $30 to spend and must buy no less than 9 hotdogs and drinks altogether. If xx represents the number of hotdogs purchased and yy represents the number of drinks purchased, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

6 hotdogs and 4 drinks

Step-by-step explanation:

4x + 1.50y = 30

For questions like this, you can do the equation that represents the price of the products first.

x + y  [tex]\geq[/tex] 9

After that, you can write the equation that represents the quantities.

Now, you just have to graph it to find the solution. When you're graphing, make sure that y is alone on one side. Here's how you rearrange the equations:

The first equation:

4x + 1.50y =30

*Subtract 4x from both sides, which leads to:

1.50 y = -4x + 30

*Divide by 1.50 on both sides, which leads to:

y = -2.66x + 20

The second equation:

x + y  [tex]\geq[/tex] 9

*Subtract x from both sides, which leads to:

y  [tex]\geq[/tex] -1x + 9

Now, use any graphing calculator (I prefer Desmos) to graph these two equations. In fact, you can just graph it on paper, too.

Here is the graph: (it is attached as a file)

You can look for any points that are on the red line but are also shaded blue. Make sure you look only in Quadrant 1- don't go into the negatives! One good point to choose would be (6,4)- this means that you buy 6 hotdogs and 4 drinks.

y=-16x^2+275x+127

Answers

Answer:

1308.6 feet

Step-by-step explanation:

Given is the quadratic equation

y= -16x^2 + 275x + 127

It has the maximum height at its vertex, x-coordinate of which is calculated by the formula:

x = -b/2ax = -275/2(-16) = 8.6 rounded to the nearest tenths

Calculating the highest point:

y = -16(8.6)^2 + 275(8.6) + 127 = 1308.6 feet rounded to the nearest tenths

Step-by-step explanation:

The value of the exponential equation is y = 3ˣ and the graph is plotted

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

y = 3ˣ   be equation (1)

Now , the y intercept of the equation is when x = 0

So , when x = 0

y = 3⁰

y = 1

Now , when y₁ = 3^1.2

The value of y₁ = 3.7

Therefore , the y intercept of the equation is 1 and the graph is plotted

Hence , the exponential equation is y = 3ˣ

A and B start toward each other at the same time from points 150 miles apart.
If A went at the rate of 20 miles an hour, at what rate must B travel if they
meet in 5 hours?

Answers

Answer:

B must travel at the rate of 10 miles per hour.

The speed at which B should travel is 10 mph

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the distance between A and B be D = 150 miles

Now , the equation will be

The speed of A = 20 mph

Let the speed of B be = B

The time required T = 5 hours

From the equation , Distance = Speed x Time

Substituting the values in the equation , we get

150 = ( A x T ) + ( B x T )

20 x 5 + ( B x 5 ) = 150

On simplifying the equation , we get

100 + 5B = 150

Subtracting 50 on both sides of the equation , we get

5B = 50

Divide by 5 on both sides of the equation , we get

B = 10 mph

Therefore , the value of B is 10 mph

Hence , the speed of B is 10 mph

A) random distribution pattern

B) uniform distribution pattern

C) logistic distribution pattern

D) clumped distribution pattern

Answer:

D: Clumped Distribution Pattern

Step-by-step explanation:

Looking at the options, the correct option is Clumped distribution pattern.

This is because in density and dispersion phenomenon, Clumped patterns will normally occur when resources get concentrated in small areas within a larger habitat or due to individuals that form social groups. However,on large spatial scales, majority of organisms will likely have clumped distributions mainly because their habitats are not distributed uniformly over wide areas.
