How much greater will Patrick’s August finance charge be if his credit card company computes finance charges using the previous balance method than if it computes finance charges using the adjusted balance method?
a.
$2.44
b.
$3.41
c.
$2.13
d.
$4.69
Answer:
B. $3.41
Step-by-step explanation:
The amount that is greater that Patrick’s August finance charge is: b. $3.41.
What is finance charges?Finance charges can be defined as the way in which a lender is compensated for lending out to a borrower.
Total amount using previous balance method
Total amount=1,466.22+28.48+40+31.76
Total amount=1,566.46
Interest=1566.46×15.40×30/360×1/100
Interest=20.10
Total amount using adjusted balance method
Total amount=1,566.46-150-115.75
Total amount=1,300.71
Interest 1,300.71×15.40×30/360×1/100
Interest=16.69
Difference=20.10-16.69
Difference=$3.41
Inconclusion the amount that is greater that Patrick’s August finance charge is: $3.41.

A fair die is rolled once. If it lands six, you win $4. However, you lose $1 if it does not land six. Let M denote the amount of money you win. Find the distribution for M. g
Answer:
m : ____ $4 ______ - $1
P(m) : __ 0.167 ____ 0.833
Step-by-step explanation:
Given that:
Fair dice is rolled once;
Winning = $4, if output is 6
If otherwise ; winning = - $1
M = amount of money won :
Distribution of M:
The amount of money won (M) is either :
$4 or - $1
Distribution of M:
Possible outcome : {1, 2, 3, 4, 5, 6}
P(winning $4) = P(rolling a 6)
Probability = number of required / number of total possible outcomes
= 1/ 6
P(losing $1) = P(not rolling a 6)
= 1 - P(rolling a 6)
= 1 - 1 /6
= 5/6
m : ____ $4 ______ - $1
P(m) : __ 0.167 ____ 0.833

Find an equation of a parabola that has curvature 6 at the origin. (Assume the parabola has its vertex at the origin, and opens upward.)
Answer:
The equation of a parabola that has a curvature 6 at the origin is [tex]f(x) = 3\cdot x^{2}[/tex].
Step-by-step explanation:
All parabolas are represented by second-order polynomials, whose standard form is:
[tex]f(x) = a\cdot x^{2}+b\cdot x + c[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficient of the parabola, dimensionless.
From Vectorial Calculus we know that curvature ([tex]K[/tex]), dimensionless, is defined by the following expression:
[tex]K = \frac{\left|\frac{d^{2}y}{dx^{2}} \right|}{\left[1+\left(\frac{dy}{dx} \right)^{2}\right]^{\frac{3}{2} }}[/tex] (Eq. 2)
Where [tex]\frac{dy}{dx}[/tex] and [tex]\frac{d^{2}y}{dx^{2}}[/tex] are the first and second derivatives of the function, respectively. Each expression is described below:
[tex]\frac{dy}{dx} = 2\cdot a\cdot x + b[/tex]
[tex]\frac{d^{2}y}{dx^{2}} = 2\cdot a[/tex]
If we know that [tex]a > 0[/tex], [tex]b = c = 0[/tex], [tex]x = 0[/tex] and [tex]K = 6[/tex], then the equation of curvature and polynomial are, respectively:
[tex]\frac{2\cdot a}{1^{\frac{3}{2} }} = 6[/tex]
[tex]a = 3[/tex]
The equation of a parabola that has a curvature 6 at the origin is [tex]f(x) = 3\cdot x^{2}[/tex].
An equation of a parabola that has curvature 6 at the origin is [tex]\rm f(x) = 3x^2[/tex].
We have to determine
An equation of a parabola that has curvature 6 at the origin.
What is the equation of a parabola that has a curvature at the origin?The equation of a parabola that has a curvature a at the origin is;
[tex]\rm f(x) = ax^2[/tex]
The value of a is given by k(0) = 8;
[tex]\rm k(0) = 2a\\\\6 = 2a\\\\a = \dfrac{6}{2}\\\\a=3[/tex]
Therefore,
The equation of a parabola that has a curvature a at the origin is;
[tex]\rm f(x) = ax^2[/tex]
[tex]\rm f(x) = 3x^2[/tex]
Hence, an equation of a parabola that has curvature 6 at the origin is [tex]\rm f(x) = 3x^2[/tex].

3. Aimee bought 9.8 meters of Geena satin cloth. One-fifth of the cloth was damaged by rats and the rest was
used to make 7 similar blouses.
A. How much cloth did she use for each blouse?
B. If she sold each blouse for P 178.25, how much money would she receive in all?
Answer:
a, 1.12m
b, P 1257.75
Step-by-step explanation:
A,
9.8m × 4/5 = 7.84m
7.84m ÷ 7 = 1.12m
B,
7 × 178.25 = P1247.75
We are required to find how much cloth she used for each blouse
cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75
Total quantity of geena satin bought = 9.8 meters
Quantity damaged by rat = 1/5 of 9.8 meters
= 0.2 × 9.8
= 1.96 meters
Total cloth used for 7 blouse = Total quantity of geena satin bought - Quantity damaged by rat
= 9.8 meters - 1.96 meters
= 7.84 meters
Cloth used for each blouse = Total cloth used for 7 blouse / 7
= 7.84 / 7
= 1.12 meters
Cost of each blouse = P 178.25
Total cost of 7 blouses = P 178.25 × 7
= P 1247.75
Therefore, cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75

All the students in the sixth grade either have pets or do not have pets at home.88%of the students have pets.6 students do not have pets.How many students are in the sixth grade?
Answer:
There are 50 students in the sixth grade.
Step-by-step explanation:
Given that 88% of students have pets which means that only 12% do not have pets. It says that only 6 students do not have pets so we can assume that 12% is equals to 6 students. We have to form an expression for the number of students.
Lets make x = total number of students,
[tex] \frac{12}{100} \times x = 6[/tex]
[tex]x = 6 \div \frac{12}{100} [/tex]
[tex]x = 6 \times \frac{100}{12} [/tex]
[tex]x = 50 \: students[/tex]
How can you use tables and graphs to show equivalent ratios?
Ratio table can help you find equivalent ratios in order to solve problems.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Ratio tables show equivalent ratios between two quantities. You can create a ratio table by multiplying (or dividing) both quantities in the ratio by the same value to find an equivalent ratio.
A ratio table can help you find equivalent ratios in order to solve problems.

If you copy a document on a​ machine, you should get a similar copy. Suppose you want to reduce a document to of its original size and you first reduce it by ​%. By what percent do you need to reduce the copy to obtain the desirable​ size?
Answer:
the numbers are missing, so I looked for a similar question:
If you copy a document on a machine, you should get a similar copy. suppose you want to reduce a document to 1/6 of its original size, and first reduce it by 25%. By what percent do you need to reduce the copy to obtain the desirable size?
You want the copy to be 1/6 of the original size = 16.67%
Since you first reduced the copy by 25%, the image is now 75% of its original size. In order to finally obtain a copy that is 16.67% of the original size, you must reduce this second copy by 1 - (16.67%/75%) = 77.78% ≈ 78%.
we can check our answer:
size of second copy x (1 - reduction)
0.75 x (1 - 0.7778) = 0.1667
