The amount of money in the account in 35 years to the nearest cent is $1629.25.

The compound interest formula is expressed as;

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

Where A is accrued amount, P is principal, r is rate,  and t is time.

Given that;

Plug the given values into the compound interest formula and solve for A.

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

A = $100( 1 + 0.08/12)^( 12 × 35)

A = $100( 1 + 0.08/12)⁴²⁰

A = $1629.25

Therefore, the accrued amount is $1,629.25.

Answer:

first you didn't tell us how much money eliana saves. you just said about Lana's saving.

The rocket reaches its maximum height at 2.25 second(s) after launch

The maximum height reached by the object is 88 feet.

The function is given as

h(t) = -16t² + 72t + 7

Differentiate the above function

So, we have the following representation

h'(t) = -32t + 72

Set to 0

-32t + 72 = 0

So, we have

32t = 72

Divide by 32

t = 2.25

Hence, the time is 2.25 seconds

In (a), we have

t = 2.25

Substitute t = 2.25 in h(t) = -16t² + 72t + 7

h(2.25) = -16(2.25)² + 72(2.25) + 7

Evaluate

h(2.25) = 88

Hence, the maximum height is 88 feet

The correct option for the given function is (D) g(-13) = 20.

Given that:

The function g has domain -20 ≤ x ≤ 5, range -5 ≤ g(x) ≤ 45, g(0) = -2, g(-9) = 6.

Let's analyze each option to see if it fits the given domain.

A. g(7) = -1

At the beginning of the problem, it is said that the domain is restricted to the range [-20, 5]. The input x = 7 here is outside this domain. That is, it cannot be true for function g without being in the domain. So g(7) is not possible.

B. g(-4) = -11

Similarly, it is said that the domain is restricted to the range [-20, 5]. The input x = -4 here is outside this domain. That is, it cannot be true for function g without being in the domain.

C. g(0) = 2

We know in the question that g(0) = -2. So, this is also the wrong option.

D. g(-13) = 20

Unlike the other options, x= -13 is in the range of -20 to 5. g(-13) = 20 is also in the range of -5 to 45. Option D is true for a function g.

x= -13 is in range and 20 is also in range. So this applies to g.

The amount in Mrs. Piazza's account after 4 years is 8960 dollars.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same, unlike compound interest where we add the interest of previous years principal to calculate the interest of the next year.

Principal(P) = 8000

time(T) = 4 years

rate(R) = 3%

simple interest = PRT/100

Simple interest = 8000 x 3 x 4 / 100

simple interest is 960 dollars

Amount after 4 years = principal + interest

                                    = 8000 + 960

                                    = 8960 dollars

Probability that the sample mean would differ from the true mean by more than 162 dollars if a sample of 71 persons is randomly selected is 50%

Normal probability distribution:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean  and standard deviation 805 , the zscore of a measure X is given by:

Z = (X - μ)/σ

s = σ/√n

In this problem, we have that:

μ = 21053, n = 71, σ = 805

s = 805/√71 = 95.53

Eiher it differs by 162 or less dollars, or it differs by more than 162 dollars. The sum of the probabilities of these events is decimal 1. So

Probability it differs by 160 or less dollars.

pvalue of Z when X = 21053 + 162 = 21215 subtracted by the pvalue of Z when X = 21053 - 162 = 20891.

X = 21215

Z = (X-μ)/σ

Z = (21215-21053)/95.53

Z = 1.69

has a pvalue of 0.091

X = 21568

Z = (X-μ)/σ

Z = (21215-21053)/95.53

Z = 1.69

has a pvalue of 0.041

0.091 -  0.041 = 0.05098

p + 0.50 = 1

The x- and y-intercepts of the graph of x +6y= 10 is 10 and 5/3.

In the given question we have to find the x- and y-intercepts of the graph of x +6y= 10.

The given equation is x +6y= 10.

To find the x intercept we have to put y=o and to find the y intercept we have to put x=0.

Firstly finding the x intercept by putting y=0 in the equation.

x +6×0= 10

x+0=10

x=10

Now finding the y intercept by putting x=0 in the equation.

0 +6y= 10

6y = 10

Divide by 6 on both side

6/6 y =10/6

y=5/3

Answer:

Table B

Step-by-step explanation:

To determine whether or not something is linear, we find the slope between two different coordinates and see if that slope remains consistent throughout the data. To find the slope between two points, use the equation (y2-y1)/(x2-x1)

Table A -->  (-1-5)/(3-2) = -6/1 = -6

Now we have to see if the slope remains consistent in "Table A" by finding the slope using two other coordinates:

(6-3)/(5-4) = 3/1 = 3

We see that the slope is not consistent in Table A, so we repeat the same steps with the other Tables to find one with a consistent slope.

Table B --> (0- -3)/(5-3) = 3/2

                  (6-3)/(9-7) = 3/2

Table B's data creates a consistent slope, so Table B represents a linear function.

The formula for the arithmetic sequence that contains a(8) = 12 and a(16) = 22 is a(n) = 13 / 4 + (5 / 4) · (n - 1).

In this problem we must derive the formula behind the arithmetic series. Arithmetic series are sets of numbers generated by expression of the form:

a(n) = a' + r · (n - 1)

Where:

If we know that a(8) = 12 and a(16) = 22, then the formula for the arithmetic formula is:

12 = a' + 7 · r

22 = a' + 15 · r

Now we find a system of two linear equations with two variables, whose solution is found by using numerical methods:

(a', r) = (13 / 4, 5 / 4)

We know that once we have the formula we extract the Raised data:

[tex] \sf \red{c {}^{2}} = \blue{(20cm) {}^{2} + (18cm) {}^{2} }[/tex]

Having the Raised data, we will add as a power and we know that:

[tex] \sf \red{20 {}^{2} } = \orange{400}[/tex]

[tex] \sf \red{18 {}^{2}} = \orange{324}[/tex]

So, to solve a power we must multiply squared and then get our result, in this case I added and then increased it by 0

[tex] \sf \red{c {}^{2} }= \blue{400cm {}^{2} + 324cm {}^{2} }[/tex]

We have the results, once that is done we will add.

[tex] \sf \red{400 + 324 }= \blue{724}[/tex]

So, we have the result we just have to put it like this:

[tex] \sf\red{c {}^{2} } = \blue{724cm {}^{2} }[/tex]

Once we have our result, we must take the square root, then the (square "²") automatically disappears.

[tex] \sf \red{c =} \green{ \sqrt{724cm} }[/tex]

There are 792 different ways for all 5 selected calculators to be non-defective.

Given, that a box contains 17 calculators, 5 of which are defective.

So, there are 12 non-defective calculators.

Now, five calculators are selected randomly from the box.

We are asked the number of ways in which all the selected calculators are defective.

So, the number of ways in which all selected 5 calculators be defective is,

C(5 , 5) i.e. we only select 5 defective calculators.

C(5 , 5) = 1.

So, there is only 1 way for all 5 selected calculators to be defective.

Now, we are asked the number of ways in which all the selected calculators are non-defective.

So, the number of ways in which all selected 5 calculators be non-defective is,

C(12 , 5) i.e. we select 5 calculators from the 12 non-defective calculators.

C(12 , 5) = (12×11×10×9×8)/(5×4×3×2×1)

C(12 , 5) = 792

So, there are 792 different ways for all 5 selected calculators to be non-defective.

Hence, there is only 1 way for all 5 selected calculators to be defective.

There are 792 different ways for all 5 selected calculators to be non-defective.
