Which scenario could be modeled with an exponential function?
Please select one of this:
The amount of money in a certificate of deposit earns 4.3% interest each year.
The amount of money in Avery's wallet increases and decreases by a different amount each week.
The amount of money in Jaylon's savings account where $125 is deducted each month.
Tim adds $10 to his savings account each week.
The scenario that could be modelled with an exponential function is when Tim adds $10 to his savings account each week.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As we know that a continuous compounding function is an exponential function. Therefore, we need to find the situation where the principal amount is invested for an infinitely long time.
A.) Since the amount is invested and a certificate of deposit is taken the amount will be invested for a fixed period of time. Thus, this is not a continuous compound function.
B.) The amount put into the account and taken out of the account varies for each term. Thus, this is not a continuous function.
C.) As in Jaylon's account the money is reduced by $125 every month, therefore, at a certain point, it will become zero. Thus, this is not a continuous compound function.
D.) As Tim adds $10 to his saving account every month, and there is no time specified, also the account will be always positive. Thus, this is a continuous compound function.
Hence, the scenario that could be modelled with an exponential function is when Tim adds $10 to his savings account each week.

Linear programming problems can also be solved using a graphing calculator. The following instructions will work for most commonly used graphing calculators, but note that they might vary slightly based on calculator model. Now that you’ve learned how to use a graphing calculator to solve linear programming problems, solve the following problems.
Part A
Consider the given system
{2x+y ≤20
{3x+2y ≤30
{x,y ≥0
Graph the inequalities on your graphing calculator, and find the vertex points of this system
Part B
In part A, you obtained the vertex points of the given system. Test these vertex points in the objective function, f(z)=4x+6y using a graphing calculator. Find the maximum point.
Answer:
A. see below for a graph
B. f(x, y) = f(0, 15) = 90 is the maximum point
Step-by-step explanation:
A. See below for a graph. The vertices are those defined by the second inequality, since it is completely enclosed by the first inequality: (0, 0), (0, 15), (10, 0)
__
B. For f(x, y) = 4x +6y, we have ...
f(0, 0) = 0
f(0, 15) = 6·15 = 90 . . . . . the maximum point
f(10, 0) = 4·10 = 40
_____
Comment on evaluating the objective function
I find it convenient to draw the line f(x, y) = 0 on the graph and then visually choose the vertex point that will put that line as far as possible from the origin. Here, the objective function is less steep than the feasible region boundary, so vertices toward the top of the graph will maximize the objective function.
The vertex points of this system are (0, 0), (0, 15) and (10, 0). And the maximum point of the system is 90.
What are systems of inequalities?At least two linear inequalities in the same variables make up a system of linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.
The given system:
2x+y ≤20
3x+2y ≤30
x, y ≥0
To find the vertex points,
first, we take inequalities in slope-intercept form.
y = 20 - 2x
And y = -3x/2 + 15
x, y ≥0
From that we interpreted the graph.
And the graph is given in the attached image.
A:
Check out the graph below. Given that the first inequality entirely encloses it, the vertices are those defined by the second inequality: (0, 0), (0, 15), (10, 0).
B:
We have objective function f(z) = 4x + 6y
To find the maximum point:
Substituting (0,0) to the function,
4x + 6y
= 4(0) + 6(0)
= 0
Substituting (0,15) to the function,
4x + 6y
= 4(0) + 6(15)
= 0 + 90
= 90
Substituting (10,0) to the function,
4x + 6y
= 4(10) + 6(0)
= 40 + 0
The maximum point is 90.
Therefore, (0, 0), (0, 15) and (10, 0) are the vertex of the system. And the maximum point is 90.

Which shape has one less side and one less vertex than a trapezoid
Answer:
An Isosceles trapezoid
Step-by-step explanation:
The shape is triangle.
What is trapezoid?In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases.
Given a trapezoid,
number of vertex trapezoid have = 4
one less vertex than trapezoid = 4 - 1 = 3
number of sides trapezoid has = 4
one less side than trapezoid = 4 - 1 = 3
the shape which has 3 sides and 3 vertex is triangle.
Hence the new shape is triangle.

What is the value of x?
According to the given figures of triangle.. The value of x is 2.
Answer:
x = 3
Step-by-step explanation:
assuming the triangle is right.
using Pythagoras' identity
(x + 2)² = x² + 4²
x² + 4x + 4 = x² + 16 ( subtract x² from both sides )
4x + 4 = 16 ( subtract 4 from both sides )
4x = 12 ( divide both sides by 4 )
x = 3
Which of these groups of values plugged into the TVM Solver of a graphing
calculator will give the monthly payment for a 25-year loan for $175,000 at
6.7% interest, compounded monthly?
A. N=25; 1% = 6.7; PV=0; PMT=; FV=-175000; P/Y=12; C/Y=12;
PMT:END
B. N=25; 1% = 6.7; PV=-175000; PMT=; FV=0; P/Y=12; C/Y=12;
PMT:END
C. N=300; 1% = 6.7; PV=-175000; PMT=; FV=0; P/Y=12; C/Y=12;
PMT:END
D. N=300; 1% = 6.7; PV=0; PMT=; FV=-175000; P/Y=12; C/Y=12;
PMT:END
Answer:
C. N=300; I%=6.7; PV=-175000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END
Step-by-step explanation:
To find the payment on a loan, a TVM solver needs the Present Value (PV) to be the loan amount, the Future Value (FV) to be zero, and N to be the actual number of payments (25×12 = 300).
Most solvers will take I% to be the annual interest rate. (An HP-12C financial calculator uses the monthly interest rate.)
The set of values needed for finding the monthly payment on this $175,000 loan at 6.7% are listed in choice C.
__
Additional comment
The sign of the cash flow is usually negative for amounts paid, and positive for amounts received. Here, the answer choices show the loan amount to be negative and the payment amount to be positive. We ordinarily expect to receive the loan amount and pay the payments. By the above criteria, the signs are reversed in this problem from what we usually expect.

Martin earns $18 dollars an hour. Which of the following inequalities represents the amount of time martin needs to work to earn at least $78 per day? 18 - t > 78 18+ t < 78 18t > 78 18t < 78
Answer:
18t >= 78
Step-by-step explanation:
Not sure if there's an equals sign in the problem that you were given, but there should be. The 18 in the inequality stands for the hourly wage. The t stands for hours worked. 18(wage) x t(hours) has to be greater than or equal to 78 in order for Martin to at LEAST $78 per day. :)

Correct Answer: (-3,4) is located in the G region!!
Step-by-step explanation:
This is simple graphing but using regions.
Each region is on a coordinate.
________________________________________________________
There are 4 Quadrants representing each region.
(x, y) is the Quadrant 1 (Top Right) which has every coordinate positive.
(-x , y) is Quad. 2 (Top left) The X coordinate is negative while the y is positive.
(-x , -y) is Quad. 3 (Bottom Left) Both axis are negatives
(x , -y) is Quad. 4 (Bottom Right) The X-axis is positive but the Y is negative.
________________________________________________________
Your question asks for what region (-3,4) is at.
We know that the location of this coordinate is in Quadrant 2 because the x is negative. (Top Right)
Now, you need to go 3 to the left of the x-axis.
Then, go 4 up the y-axis.
Your region for this coordinate is "G"
