Answer:

  A = 1000·1.04^5

Step-by-step explanation:

When 4% of the amount in the account is added to the amount in the account, the result is that amount is multiplied by 1.04:

  amount + 0.04×amount = amount×(1 + .04) = 1.04×amount

The account is multiplied this way for each of 5 years. An exponent is used to signify repeated multiplication, so we can write the account balance as ...

  A = ((((1000×1.04)×1.04)×1.04)×1.04)×1.04 = 1000×1.04^5

The exponential equation that represents the value of the account, ( A ), after five years is [tex]\[ A = 1000 \times (1.04)^5 \][/tex]

To determine the value of Maria's savings account after five years with annual compounding interest, we use the formula for compound interest:

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

Given:

( P = 1000 ) dollars (initial investment)

( r = 0.04 ) (4% interest rate per year)

( n = 1 ) (compounded annually)

( t = 5 ) years

Now, substitute these values into the formula:

[tex]\[ A = 1000 \left(1 + \frac{0.04}{1}\right)^{1 \cdot 5} \][/tex]

[tex]\[ A = 1000 \left(1 + 0.04\right)^5 \][/tex]

[tex]\[ A = 1000 \times (1.04)^5 \][/tex]

Calculate [tex]\( (1.04)^5 \)[/tex]:

[tex]\[ (1.04)^5 \approx 1.21665 \][/tex]

Now multiply by 1000:

[tex]\[ A \approx 1000 \times 1.21665 \][/tex]

[tex]\[ A \approx 1216.65 \][/tex]

Therefore, the value of Maria's savings account at the end of five years, with annual compounding interest at 4%, is approximately [tex]\( \$1216.65 \)[/tex].

To summarize, the exponential equation that represents the value of the account, ( A ), after five years is:

[tex]\[ A = 1000 \times (1.04)^5 \][/tex]

Answer:

  175 hot dogs

Step-by-step explanation:

The new price will be $3.85 + 0.55 = $4.40. Since the price has increased by a factor of 4.40/3.85 = 8/7, the number of hot dogs sold, which is inversely proportional, will be ...

  (7/8)·200 = 175 . . . hot dogs sold at the higher price

The vendor can expect to sell approximately 233 hot dogs if the price is increased by 55 cents.

To determine how many hot dogs the vendor can expect to sell if the price is increased by 55 cents, we can use the inverse proportionality relationship between the number of hot dogs sold and the price charged.

First, let's set up a proportion with the initial price and number of hot dogs sold:

$3.85 / 200 = (new price + $0.55) / x

Next, we can cross multiply and solve for x:

x = (200 * ($3.85 + $0.55)) / $3.85

Calculating this expression gives us a value of x ≈ 233.77.

Since the number of hot dogs sold must be a whole number, we round down to the nearest whole number, giving us an estimated value of 233 hot dogs.

Answer:

t = 20.3 years

Step-by-step explanation:

I am assuming that this amount of money invested is compounding annually, so I am going to use the formula that goes along with that assumption:

[tex]A(t)=P(1+r)^t[/tex]

where A(t) is the amount at the end of compounding, P is the initial investment, r is the interest rate in decimal form, and t is the time in years.  We are solving for t.  Right now it is the exponent, but we have to get it down from that position in order to solve for it.  The only way we can do that is to eventually take the natural log of both sides.  But let's write the equation first and then do some simplifying to make things a bit easier mathematically:

[tex]19,700=5,500(1+.065)^t[/tex] and

[tex]19,700=5,500(1.065)^t[/tex]

We will divide both sides by 5,500:

[tex]3.58181818=(1.065)^t[/tex]

Taking the natural log of both sides gives us:

[tex]ln(3.58181818)=ln(1.065)^t[/tex]

The power rule for logs (both common and natural) tells us that once we take the log or ln of a base, the exponent comes down out front:

ln(3.58181818) = t ln(1.065)

Now we can divide both sides by ln(1.065) and do the math on our calculators to find that

t = 20.2600 or, to the tenth of a year,

t = 20.3 years

It will take for $5500 to grow to $19700 at a 6.5% interest rate, approximately 19.7 years for the account to reach.

The question involves calculating the amount of time it takes for an investment to grow to a certain value given a fixed annual interest rate. This is a common problem in personal finance and uses the concept of compound interest. To find the time needed for an initial investment of $5500 to grow to $19700 at an annual interest rate of 6.5%, we can use the formula for compound interest:

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

Where:

A is the amount of money accumulated after n years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (decimal).

n is the number of times that interest is compounded per year.

t is the time in years.

In this case, interest is compounded annually so n = 1. We rearrange the formula to solve for t:

t = log(A/P) / (n*log(1 + r/n))

Where log is the logarithm function. We substitute our known values:

t = log(19700/5500) / (1*log(1 + 0.065/1))

Calculating this gives:

t ≈ log(3.5818) / log(1.065)

t ≈ 19.7

Answer:

(9,5)

Step-by-step explanation:

Linear combination (also known as elimination) is trying to somehow combine the equations together so that it eliminates one variable in order to solve for the other one.

So you have

-4x+9y=9

  x-3y =-6

In elimination, you want the equations to be in the same form which they are here in this case.  You want one of the columns to contain opposites or sames.

If opposites, you add the equations.

If sames, you subtract the equations.

We have neither opposites or sames in either of the first two variable columns which is where we want one of these columns to be.

So I'm going to multiply the bottom equation by 3.  This is not the only way. This is the way I'm going to do it. You could decide to multiply the bottom equation by 4 or -4 or -3 instead.  

So anyways multiply bottom equation by 3. This is what my system looks like now:

 -4x+9y=9

  3x-9y=-18

  ----------------Now we get to add this equations because the 2nd column,

                     the y column, we have opposites.

------------------------adding now

 -1x+0y=-9                  -4+3=1 and -9+9=0  and 9+-18=0      

  -x      =-9                    -1x=-1*x=-x     and 0y=0*y=0

   x      =9                       Take opposite of both sides

Now once we find one variable we must obtain the other variable by replacing x with 9 and solving for y in one of the equations (don't use both-just choose one- doesn't matter which)

x-3y=-6 was the second equation before manipulation

Plug in 9 for x

9-3y=-6

Subtract 9 on both sides

 -3y=-6-9

  -3y=-15  

Divide both sides by -3

    y=5

So the solution is (x,y)=(9,5)

[tex]\sqrt{(x2 - x1)^{2}  + (y2 - y1)^{2} }= \\ \\\sqrt{(-4 - (-1))^{2}  + (-1 - 4)^{2} }= \\\\\sqrt{-3^{2}  + -5^{2} }= \\\\\sqrt{9  + 25 }=\\\sqrt{34 }=\\5.83[/tex]

Distance between each pair of points is: 5.83

The distance formula, derived from the Pythagorean theorem, is used to find the distance between two points. You subtract and square the x-coordinates, do the same with the y-coordinates, sum those results, and take the square root of the sum to get the distance.

The distance formula in mathematics is used to determine the distance between two points in a coordinate plane. The formula is derived from the Pythagorean theorem and is represented as D = √[(x2-x1)² + (y2-y1)²]. Let's say we have two points A1(x1, y1) and A2(x2, y2).

The final result gives you the distance between the two points in the cartesian plane.

To write an equation to determine how many miles Marcus biked, we can use the given information. Let's assume that the number of miles Marcus biked is represented by the variable 'm'. According to the problem, Jenny biked 3 miles less than twice the number of miles Marcus biked. So, we can write the equation as: 2m - 3 = 4.

To solve this equation, we need to isolate the variable 'm'. Adding 3 to both sides of the equation, we get: 2m = 7. Finally, dividing both sides by 2, we find that Marcus biked 3.5 miles.

The students that take both: [tex]\rm n(C\cap F) = 4[/tex]

Total Students: n(S) = 80

Students that take Consumer, French, or both:

[tex]\rm n(C\cup F) = n(F) + n(C) - n(C\cap F)[/tex]

Since we want to find when they are equal, set them equal to each other:

15+0.02m=4.69+0.08m

simplifying this equation gives

10.31+0.02m=0.08m

subtract 0.02m from both sides

10.31=0.06m

divide both sides by 0.06

  10.31 = 0.06 m . . . . . subtract 4.69+0.02m

  10.31/0.06 = m = 171.8333... ≈ 172 . . . . minutes at equal cost

There are 60 minutes in an hour, so ...

  172 minutes = 120 minutes + 52 minutes = 2 hours + 52 minutes

Plan A will cost the same as Plan B for 2 h 52 min of usage.

Area=[tex]\pi *5^2=3.14*5^2=78.5ft^2\\\\=79ft^2[/tex]

Answer:

[tex]y-12=-\frac{3}{4}(x+4)[/tex]

Step-by-step explanation:

we know that

The equation of the line into slope point form is equal to

[tex]y-y1=m(x-x1)[/tex]

In this problem we have

[tex](x1,y1)=(-4,12)[/tex]

[tex]m=-\frac{3}{4}[/tex]

substitute

[tex]y-12=-\frac{3}{4}(x+4)[/tex]
