Neal opened a savings account 11 years ago with a deposit of $2,335.69. The account has an interest rate of 4.3% compounded daily. How much interest has Neal earned? (3 points)

$1,412.52

$2,436.12

$1,375.75

$3,748.21

Answers

Answer: $1,412.52

Step-by-step explanation:

Formula to calculate the accumulated amount if P principal invested for t years at a rate of interest r that compounded daily is given by:-

[tex]A=P(1+\dfrac{r}{365})^{365t}[/tex]

Given: P= $2,335.69

r= 4.3%= 0.043

t= 11 years

Then,

[tex]A=2335.69(1+\dfrac{0.043}{365})^{365\times11}\\\\=2335.69(1+0.000117808219178)^{4015}\\\\=2335.69(1.000117808219178)^{4015}\\\\= 2335.69(1.6047566747)\\\\=3748.09044309\approx3748.21\\\\\Rightarrow\ A=\$3748.21[/tex]

Interest earned = A-P

= $3748.21- 2335.69.

= $1412.52

Hence, Neal earned $1,412.52 as interest.

Kevin mowed 12 lawns and earned a total of $60.
Which rate represents the amount of money earned per lawn?

Answers

Answer:

$5

Step-by-step explanation:

$60 earned for moving 12 lawns

Amount of money per lawn is:

$60/12= $5

Answer is amount per lawn is $5

Answer:

$5

or

$5 / 1 lawn

Step-by-step explanation:

The process is quite simple - especially since you already have half of the answer.  The question says money per lawn.  The creator of the problem gave away a lot of the answer.  They already tell us the rate.  Now all ou have to do is plug the numbers in:

Money per lawn

Money / lawns (The slash is used to represent per)

What is the money? $60. So plug that in:

$60 / lawns

How many lawns? 12.  Plug that in:

$60 / 12 lawns

Now, all you have to do is either simplify the fraction or divide the denominator by the numerator - whichever one you prefer.  In that case, the rate can be any of the following:

$5

$5 / 1 lawn

Use the figure to the right to find the value of PT. T is the midpoint of PQ PT=7x+9 and TQ=9x-5

7x + 9 = 9x - 5\\

9 + 5 = 9x - 7x\\

H0: p H1: p
Use the following codes to enter the following symbols: ? enter >= ? enter <= ? enter ! =

Answers

Answer:

H0 : p = 0.75  against    H1: p > 0.75  One tailed test.

Step-by-step explanation:

We state our null and alternative hypotheses as

H0 : p = 0.75  against    H1: p > 0.75  One tailed test.

In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.

The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.

As H0 is supposed to be less than we choose H1 to be greater than equality.

Approximating to the nearest hundredth implies that, only to digits after the decimal point is needed

This is:

191._ _

The third digit after the decimal point will approximated using the approximation rule;

Since, the third digit after the decimal point (3) is not up to 5, it'll be approximated to 0 and added to the second digit (6)

So, we have:

The next digit is calculated as 6 + 0 = 6

flying against the wind, a jet travels 4600 miles in 5 hours. flying with the wind, the same jet travels 4200 miles in 3 hours. what is the rate of the jet in still air and what is the rate of the wind?

Answers

Answer:

The rate of the jet in still wind is 1160 MPH and the rate of the wind is 240 MPH.

Step-by-step explanation:

Distance equals rate times time (d = rt)

Against the wind, the rate is:

4600 = r * 5

r = 4600/5 = 920 MPH

With the wind, the rate is:

4200 = r * 3

r = 4200/3 = 1400 MPH

Let W be the rate of the wind in MPH. We know that:

(rate of the jet against the wind) + (rate of the wind) = (rate of the jet with the wind ) - (rate of the wind), so:

920 + W = 1400 - W

2W = 480

W = 240 MPH

And the speed of the jet in still air would be:

1400 - 240 = 1160 MPH

State the trigonometric substitution you would use to find the indefinite integral. Do not integrate. (25 + x2)−6 dx x(θ) =

Answers

Answer:

x(θ) = 5 tan θ

Step-by-step explanation:

Given that:

[tex]\int (25+x^2)^{-6} \ dx[/tex]

we are to state the trigonometric substitution to be used to find the indefinite integral.

Suppose u is the variable and a is the constant

u = x

a = 5

So; (a² + x²)ⁿ

which is a trigonometric substitution for x = a tanθ

Then,

x(θ) = 5 tan θ

In this exercise we have to use the knowledge of trigonometric substitution to calculate the indefinite integral, so we have that this is:

[tex]x(\theta) = 5 tan \theta[/tex]

Knowing that the indefinite integral corresponds to:

[tex]\int\limits {(25+x^2)^{-6}} \, dx[/tex]

we are to state the trigonometric substitution to be used to find the indefinite integral. Suppose u is the variable and a is the constant:

[tex]u = x\\a = 5\\(a^2 + x^2)^n[/tex]

Which is a trigonometric substitution for:

[tex]x = a tan\theta\\x(\theta) = 5 tan \theta[/tex]
