Faye’s bank charges her a $2.25 service fee every time she uses an out-of-network ATM. If Faye uses an out-of-network ATM twice a week, how much money does she pay in service fees every year?
a.
$240.25
b.
$225.00
c.
$200.75
d.
$234.00
The amount of money that is being paid by Faye as service fee every year is: d. $234.00.
Given the following data:
Service fee = $2.25Number of times = 2Time = 1 yearTo determine the amount of money that is being paid by Faye as service fee every year:
How to solve a world problem.First of all, we would calculate the amount of money she pays for the service in a week as follows:
[tex]Cost = 2.25 \times 2[/tex]
Cost per week = $4.50
Note: There are 52 weeks in a year.
Thus, we would multiply the cost per week by 52:
[tex]Total \;cost = 52 \times 4.5[/tex]
Total cost = $234.00

Which shows the factored form of M^2+ 40m + 400
The factored form of the given quadratic equation M² + 40M + 400 is (M + 20)², achieved by noticing that the equation is a perfect square trinomial.
Explanation:The question asks you to find the factored form of the polynomial equation M² + 40M + 400. We can factor this equation by grouping. Factoring is the process of breaking down a complex equation into its simplest terms or variables.
Factoring the Equation
The first step to factoring is to look for a common factor among all the terms. In this case, we don't have one, so we move to the next step: factoring quadratics. A quadratic is an equation where the highest exponent is 2.
The equation given, M² + 40M + 400, it is a perfect square trinomial because 20² equals 400. Factored form of perfect square trinomial (a + b)² = a² + 2ab + b².
Setting a=M and b=20 (since (20)²=400), hence this polynomial factors to be (M + 20².

What is the maximum number of consecutive positive integers that can be added together to create a sum less than 400?
To find the maximum number of consecutive positive integers that sum to less than 400, solve the inequality n(n+1)/2 < 400. The largest integer n that satisfies the inequality is 28, meaning up to 28 consecutive integers can be used.
Explanation:To solve the question on the maximum number of consecutive positive integers that can be added together to create a sum less than 400, we can use the formula for the sum of an arithmetic series. The sum of the first n integers is n(n+1)/2. We want this sum to be less than 400, so we need to solve the inequality n(n+1)/2 < 400 for n.
The inequality simplifies to n^2 + n - 800 < 0. The roots of the equation n^2 + n - 800 = 0 can be found using the quadratic formula or by factoring when possible. The largest integer n that satisfies the inequality will give us the answer. Upon solving, we can find that n = 28 will be the largest integer before the sum exceeds 400. Therefore, we can add up to 28 consecutive positive integers to stay under the limit of 400.

A ball is thrown vertically upward from the top of a 200 foot tower, with an initial velocity of 5 ft/sec. Its position function is s(t) = –16t2 + 5t + 200. What is its velocity in ft/sec when t = 3 seconds?
Answer:
The velocity would be - 91 ft/sec.
Step-by-step explanation:
Given,
The function that shows the position of the ball after t seconds,
[tex]s(t) = -16t^2 + 5t + 200[/tex]
Since, velocity is the changes in position with respect to time,
That is, if v(t) is the velocity of the ball after t second,
[tex]\implies v(t)=\frac{d}{dt}(s(t))[/tex]
[tex]=\frac{d}{dt}(-16t^2 + 5t + 200)[/tex]
[tex]=-32t+5[/tex]
Hence, the velocity after 3 seconds is,
[tex]v(3)=-32(3)+5=-96+5=-91\text{ ft per seconds}[/tex]

Use the square root property of equality to solve (x – 3)2 = –4. The solutions are a. -1 or 7 b. 1 or 5 c. 3+- 2i d. 3+-4i
Answer:
The solution is 3 ± 2i . The correct option is C.
Step-by-step explanation:
using the square root property of equality to solve (x - 3)² = -4
we have;
(x - 3)² = -4
Take the square root of both-side
√(x - 3)² = ±√-4
x - 3 = ±√4 × √-1
Not that square root of -1 is i
x - 3 = ±2i
Add 3 to both-side of the equation
x -3 + 3 = 3 ± 2i
x = 3 ± 2i
Therefore, the solution are 3 ± 2i
Jessica is stacking items on a shelf. She has large books that weigh 5 pounds each and medium books that weigh 3 pounds each. The shelf should hold at most 50 pounds. Let x represent the number of large books. Let y represent the number of medium books. Which inequality represents this situation?
Answer:
5x + 3y ≤ 50
Step-by-step explanation:
Given,
The weight of each large book = 5 pounds,
And, the weight of each medium book = 3 pounds,
Thus,
The total weight in pounds of x large books and y medium books = x × weight of each large book + y × weight of each medium book
= 5x + 3y
According to the question,
Total weight ≤ 50 pounds
( Note : at most = less than equal )
⇒ 5x + 3y ≤ 50
Which is the required inequality.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the population be = x
Let the number of years be time = t
Let the percentage of increase be = 5 %
Now , dx / dt = rate of increase of population per change in time
Here, ( dx/dt ) ∝ x
where , x is the population at any time t
Then ( dx/dt ) = Ax
where A is the proportionality constant.
Now , the equation is dx / x= A dt
On , Integrating with respect to x , we get
ln x = At + c
where c is the integration constant
So , on simplifying the equation , we get
Taking exponents on both sides of the equation ,
[tex]x=e^{rt + c}[/tex]
Let [tex]k=e^{c}[/tex]
So , the equation is
[tex]x= ke^{rt}[/tex]
Now , r is the rate of increase, and k is the initial population be x₀
And to find the time t taken to attain double population, so x = 2x₀
[tex]x= ke^{rt}[/tex]
Substituting the values in the equation , we get
[tex]2x_{0} =x_{0} e^{0.05t}[/tex]
[tex]2 = e^{0.05t}[/tex]
Taking logarithm on both sides,
[tex]ln 2=ln ( e^{0.05t} )[/tex]
0.69314=0.05t
t = 0.69317 / 0.05
t = 13.86294 years
Therefore , it takes 13.86294 years to double population
And , 13.86294 ≈ 14 years
Hence , The population of the country will double its population in approximately 14 years at a rate of 5 % growth rate every year

The money saved by Natalie if, Natalie uses a 15% off coupon when she buys a camera, The original price of the camera is $45.00, is $6.75.
What is percentage?The percentage is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
Given:

Calculate the money saved by Natalie as shown below,
The money saved by the Natalie = 15% of the original price
The money saved by the Natalie = 15 / 100 × 45
The money saved by the Natalie = 0.15 × 45
The money saved by the Natalie = 6.75

The 100-meter race times at a state track meet are normally distributed with a mean of 14.62 seconds and a standard deviation of 2.13 seconds. Using the Standard Normal Probabilities table, what is the approximate probability that a runner chosen at random will have a 100-meter time less than 15.5 seconds? a.0.1894
b. 0.3409
c. 0.6591
d. 0.7910
e. 0.8106
To solve this problem, we use the t statistic. The formula for z score is:
z = (x – u) / s
where x is the sample value = 15.5 seconds or below, u is the sample mean = 14.62 seconds, s is standard dev = 2.13 seconds
z = (15.5 – 14.62) / 2.13
z = 0.41
Using standard distribution tables at z = 0.41, the value of P is:
P = 0.6591 = 65.91%
Hence there is a 65.91% chance the runner will have less than 15.5 seconds of time
