A student has a savings account earning 3% simple interest. She must pay $1200 for first-semester tuition by September 1 and $1200 for second-semester tuition by January 1. How
much must she earn in the summer (by September 1) to pay the first-semester bill on time and still have the remainder of her summer earnings grow to $1200 between September 1
and January 1? (Round your answer to the nearest cent.)
Using simple interest, it is found that she needs to earn $2,391.07 during the summer.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
A(t) = A(0)(1 + rt)
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.For this problem, the objective is to have $1200 in 3 months = 0.25 years, hence the parameters are given as follows:
A(0.25) = 1200, t = 0.25, r = 0.03.
Hence we have to solve for A(0):
A(0)(1 + 0.03 x 0.25) = 1200
A(0) = 1200/(1 + 0.03 x 0.25)
A(0) = $1,191.07.
She also needs to earn $1,200 to pay the first-semester bill on time, hence:
1200 + 1191.07 = $2,391.07.
She needs to earn $2,391.07 during the summer.

Rajesh is in charge of equipment for the complex. The last shipment of ping-pong balls was normally distributed with a mean weight of 2.7 grams and a standard deviation of 0.1 gram. The 100-pound weights he orders from the manufacturer for the fitness center are normally distributed with mean weight 100.2 pounds and standard deviation 0.1 pound.
A) Which distribution has the larger standard deviation?
B) Which distribution is more dispersed? Explain.
The standard deviation of the fitness center is larger than the standard deviation of the last shipment
Which distribution has the larger standard deviation?The given parameters are:
Distribution: Normal distribution
The last shipment
Mean weight = 2.7 grams
Standard deviation = 0.1 gram.
Fitness center
Mean weight = 100.2 pounds
Standard deviation = 0.1 pound
In the above parameters, we can see that the fitness center has a larger mean weight than the last shipment, while they both have the same standard deviation
This means that the standard deviation of the fitness center is larger than the standard deviation of the last shipment
And so, the distribution of the fitness center is more dispersed

Triangle DHS has the coordinates D(-5, 1), H(-4, 5) and S(-1, 2). What are the coordinates of D'H'S' if DHS is translated 2 units right and 1 unit down?
The new coordinates after translating 2 units right and 1 unit down are D'(-3,0), H'(-2,4) and S'(1,1) respectively.
Given, triangle DHS has the coordinates D(-5, 1), H(-4, 5) and S(-1, 2). Now, we have to find the coordinates of D'H'S' if DHS is translated 2 units right and 1 unit down.
A translation is a transformation that occurs when a figure is moved from one location to another location without changing its size, shape or orientation. In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved.
To translate the point P(x,y), 'a' units right and 'b' units down, use P′(x+a,y-b).
Now, let's proceed to solve the question according to above listed points accordingly.
D(-5, 1), H(-4, 5) and S(-1, 2), these coordinates are translated 2 units right and 1 unit down. So, we will simply add 2 to the x-coordinate of the points and will subtract 1 from the y-coordinate.
Let's translate D, H and S accordingly into D', H' and S'.
D(-5,1)⇒ D(-5+2, 1-1)⇒ D'(-3,0)
H(-4,5)⇒ H(-4+2, 5-1)⇒ H'(-2,4)
S(-1,2)⇒ S(-1+2, 2-1)⇒ S'(1,1)
Therefore, the new coordinates after translation are D'(-3,0), H'(-2,4) and S'(1,1) respectively.

Find the following given the function f(x)=
Answer:
The function f defined by the formula f(x) = 2x +1 can be expressed as: f(4) = 9; f(-5) = - 9, f(0) = 1,
The function of a function defines and explains the relationship between two different variables. From the given information, we are meant to replace x with the following given options and solve for the value of x.
f(4) = 2(4) + 1
f(4) = 8 + 1
f(4) = 9
f(-5) = 2(-5) + 1
f(-5) = -10 + 1
f(-5) = - 9
f(0) = 2(0) + 1
f(0) = 0 + 1
f(0) = 1
Step-by-step explanation:
Basically first you have to check what the f(x) fits into what category.
The picture shows different equations based on what the f(x) is.
In this case, f(x) is 7. So first check is 7 greater than 5, YES. But check with the next one too. Is 7 less than or equal to 5, NOPE
So your equation your going to be substituting with is x squared-x
Little bit stuck still? Here:

The line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8).
The equation of a line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8) is 2y - 5x = 0.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's suppose the equation of that line as the slope-intercept form is
y = mx + c
Where m is the slope while c is the y-intercept.
Now this line is parallel to a line that passes through points (8, 3) and
(10, 8) thus meaning the slope of both lines must be the same.
So,
Slope associated with points (8, 3) and (10, 8) ⇒
m = difference in y's coordinate / difference in x's coordinate
m = (8 - 3)/(10 - 3)
m = 5/7
So our equation will be y = (5/7)x + c
Since it is passing through the origin or (0,0) so it will satisfy the coordinate.
Therefore,
0 = (5/7)0 + c ⇒ c = 0
It means y = (5/7)x ⇒ 7y - 5x = 0 will be the equation.
Hence "The equation of a line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8) is 2y - 5x = 0".

Answer:
y -2 = 3/7(x +8)
Step-by-step explanation:
You want a point-slope equation of the line through points (-8, 2) and (6, 8).
SlopeThe slope of the line is given by the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . where (x1, y1) and (x2, y2) are points on the line
Using the given points, we find the slope to be ...
m = (8 -2)/(6 -(-8)) = 6/14 = 3/7
Point-slope equationThe equation of a line with slope m through point (h, k) is written in point-slope form as ...
y -k = m(x -h)
Here, we have m=3/7, and (h, k) = (-8, 2). This means the equation of the line is ...
y -2 = 3/7(x +8)

Step-by-step explanation:
Bank A charges a monthly service fee of $5.00 and a per-check fee of $0.15,
B while Bank B charges a monthly service fee of $2.50 and a per-check fee of
$0.35. Which of these numbers of monthly checks will cause Bank A to
charge less in fees than Bank B?
for 5 monthly checks, both banks charge the same amount.
for x < 5, Bank B charges less.
for x > 5, Bank A charges less.
For what numbers of monthly checks will Bank A charge less than Bank B?Bank A charges a fixed fee of $5.00 plus $0.15 per-check fee.
So, if you do x monthly checks, Bank A will charge you:
A(x) = $5.00 + $0.15*x
Bank B charges a service fee (fixed) of $2.50 plus $0.35 per check, then for x monthly checks they charge:
B(x) = $2.50 + $0.35*x
Both banks will charge the same amount when:
A(x)= B(x)
So we need to solve the linear equation:
$5.00 + $0.15*x = $2.50 + $0.35*x
$5.00 - $2.50 = $0.35*x + $0.15*x
$2.50 = $0.50*x
$2.50/$0.50 = x = 5
So, for 5 monthly checks, both banks charge the same amount.
for x < 5, Bank B charges less.
for x > 5, Bank A charges less.

Answer:
B
Step-by-step explanation:
x - y = 0 ( add y to both sides )
x = y → (1)
6x + 5y = - 22 → (2)
substitute x = y into (2)
6y + 5y = - 22
11y = - 22 ( divide both sides by 11 (
y = - 2
since x = y then x = - 2

Find an equation for the tangent line to the graph of f at x= 11.
Tangent line: y = ??
The equation of the line tangent to the curve at x = 11 is y = (5 / 432) · x - 43 / 432.
What is the equation of the line tangent to a given curve?
Herein we have a rational function, of which we must derive the equation of the line tangent to the curve at a given point. First, find the first derivative of the function by derivative rules:
f'(x) = [(6 · x + 6) - 6 · (x - 9)] / (6 · x + 6)²
f'(x) = 60 / (6 · x + 6)²
Second, evaluate the first derivative of the function:
f'(11) = 60 / (6 · 11 + 6)²
f'(11) = 5 / 432
This value represents the slope of the tangent line.
Third, calculate the y-value of the curve:
f(11) = (11 - 9) / (6 · 11 + 6)
f(11) = 1 / 36
Fourth, determine the intercept of the tangent line:
b = 1 / 36 - (5 / 432) · (11)
b = - 43 / 432
The equation of the line tangent to the curve at x = 11 is y = (5 / 432) · x - 43 / 432.
