Answer:
-3x + 4y = 3
Step-by-step explanation:
Ax + By = C standard form
y + 3 = 3/4 (x + 5) | ×4
4(y + 3) = 3(x + 5)
4y + 4·3 = 3x + 3·5
4y + 12 = 3x + 15
-3x + 4y = 15 - 12
The equation in standard form is -3x + 4y = 3
Determine whether the following quadratic function has a maximum of a minimum value. Then find the maximum or minimum value and where it occurs.
F(x)=-3x²+18x+3
Select the correct choice below and fill in the answer boxes to complete of
(Simplify your answers.)
The function has a maximum value of ___at x=____.
The function has a minimum value of ___at x= ___.
The function has a maximum value of 30 at x = 3
How to determine if the quadratic function has a maximum or minimum?From the question, we have the following equation that can be used in our computation:
F(x) = -3x²+18x+3
This can be expressed properly as
F(x) = -3x² + 18x + 3
A quadratic function is represented as
F(x) = ax² + bx + 3
By comparison, we have
a = -3
For a quadratic function to have a maximum value, the value of a must be less than 0
This means that the function has a maximum value because -3 is less than 0
Solving further, we have
F(x) = -3x² + 18x + 3
Differentiate and set to 0
-6x + 18 = 0
So, we have
x = 3
Substitute x = 3 in F(x)
F(3) = -3(3)² + 18(3) + 3
Evaluate
F(3) = 30
This represents the maximum value

What is an area of the sector?
The area of the sector refers to the area encircled by a circle's sector. A sector always originates from the center of the circle.
What is curved surface area?
The area with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Total Surface Area: This is the combined area of the bases and the curved surface.
Here, we have
Radius = 28cm, Height = 96cm
L² = 96² + 28²

a specific pendulum has a period of t, given by the equation above. if the length of the string, l, is increased, the period will
If the length of the string, l, is increased, the period will; Increase
How to solve simple pendulum problems?The time period of a simple pendulum is given by the formula;
t = 2π√(l/g)
Where;
t is time period
l is length of the string
g is acceleration due to gravity.
We can see from the equation above that for simple pendulum, time period is directly proportional to length of the string; (t ∝ l ).
However, we see that the time period is inversely proportional to acceleration due to gravity ( t ∝ 1/g) .
Now, as we are told, If length(l) of the string is increased, then it means that the time period (t) of the pendulum will also increase.

Var( 3y+ 2)
The expectation, E(3y +2) and variance, Var(3y+2) of the random variable are 13.4 and 19.44 respectively
How to determine the expectation and variance of a random variable?The expectations or expected value E(y) of a random variable can be thought of as the “average” value of the random variable. It is also called its mean
By definition:
if y = ax + b
then E(y) = aE(x) + b
where a,b = constant
The variance V(y) of a random variable is the measure of spread for the distribution of a random variable that determines the degree to which the values of a random variable differ from the expected value
By definition
if y = ax + b
V(b) = 0
V(y) = V(ax) + V(b)
= a²V(x) + 0
where a,b = constant
Given: E(y)= 3.8 and Var(y)= 2.16
Calculate E( 3y +2) and Var( 3y+ 2)
E(3y +2) = 3E(y) + 2 since E(y) = 3.8
= 3×3.8 + 2
= 11.4+2
= 13.4
Var(3y+2) = 3²Var(y) + 0

Percentage is the ratio in which the denominator is 100. To calculate the percentage we multiply the obtained value by 100.
We are given 62 hours and 3 days
Now 1 day has 24 hours
Hence 3 days will have 3*24 = 72 hours
Now To find the percentage we first have to find the ratio of 62 and 72
And to do that we divide 62 by 72
we get 62/72 = 0.86
To get the percentage we multiply this value by 100
0.86 * 100= 86%

Statements Reasons
∠3 = ∠5 m || n, alternate interior angles
∠5 = ∠13 a || b, corresponding angles
∠3 = ∠13 substitution property: ∠3 =∠5 and ∠5 =∠13
Find x and y. Give reasons to justify your solution.
The angles will be x = 8° and y = 21°
given information:
∠AOB = 180°
∠EOG = 90°
∠EOF and ∠FOG are complementary angles. Complementary angles are those whose sum is equal to 90° and it is given to us in the question.
∠EOG = ∠EOF + ∠FOG
90° = 27° + 3y
90 - 27 = 3y
63 / 3 = y
y = 21°
Similarly ∠AOE , ∠AOG and ∠GOB are supplementary to each other. Supplementary angles are those whose sum is equal to 180°
∠AOB = ∠AOE + ∠AOG + ∠GOB
180° = x + 90° + 8x + 18°
180 - 90 - 18 = 9x
9x = 72
x = 72 / 9
x = 8°
Hence we can clearly say that x = 8° and y = 21°

Use factoring to solve the polynomial equation:
x(x−2)=48
Answer (Type as x = n or x = m):
The solution of the polynomial equation x(x - 2) = 48 by factoring is x = 8 or x = -6
How to use factoring to solve the polynomial equation?Given the polynomial equation x(x−2) = 48
x(x−2) = 48
x² - 2x = 48
x² - 2x - 48 = 0
x² -8x+6x - 48 = 0
By factoring the equation, we have:
x(x-8) + 6(x-8) = 0
(x-8) (x+6) = 0
x-8 = 0 or x+6 = 0
x = 8 or x = -6
Therefore, the solution of the polynomial equation is x = 8 or x = -6. Type x = 8 or x = -6 in the answer box

Area of rectangle: The area of a rectangle is the product of its length 'a' and width or breadth 'b'. So, Area of Rectangle = (a × b) square units.
What is triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.
Area of triangle: The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.
Here we have a diagram PQRTS comprising the triangle PQT and rectangle QRTS.
Given: PS = 9 units & QR = 5 units
⇒ PT = 4 units, RS = QT= 6 units
The area of ΔPQT= M = 1/2*b*h = 1/2*PT*QT

⇒ M = 12 square units
Now, the area of rectangle QRTS = N = l*b = QT*TS = 6*9 = 54 square units
⇒ N = 54 square units
Now, the area of whole diagram = area of triangle A + area of rectangle B
⇒ M + N = (12 + 54)square units = 66 square units.

The annual percentage yield (APY) of Russ is 4.39 %
What is Annual Percentage Yield?
The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest.
Given data ,
Deposit amount of Russ = $ 4500
Interest rate R = 4.3 %
And it is given that the interest rate is compounded daily , so
Interest rate R = 4.3 % / 365
= 0.043 / 365
= 0.0001178
Now , The annual percentage yield (APY) is calculated as
The interest amount = 4500 x ( 1 + 0.0001178 )³⁶⁵
= 4500 x ( 1.0001178 )³⁶⁵
= 4500 x 1.04393211
= 4697.694
≈ 4697.69
Therefore , the interest will be
= 4697.69 - 4500

Now , the annual percentage yield (APY) is given by
= Interest / Deposit
= 197.69 / 4500

If the mean is 48.69 and the standard deviation 17.993 assuming the distribution of age is normal calculate the number of people who should be 25 years of age or less
Using probability of a randomly chosen person, 270 people should have age less than or equal to 25.
From the given question,
Mean = 48.69
Standard Deviation = 17.993
We have to find the distribution of age is normal calculate the number of people who should be 25 years of age or less.
If 'X' is the age of a randomly selected individual in the sample, and that individual has a mean and a standard deviation that are normally distributed, then that individual's age has a standard normal score of -
Z = X- Mean/standard deviation
Z = X-48.69/17.993
Thus, Z-score for 25 year old is -
Z = 25 -48.69/17.993
Z = -23.69/17.993
Z = -1.317
Z= -1.317(approx)
The probability of a randomly chosen person to be 25 years of age or less in the sample is -
P(X < 25) = P(Z < -1.317)
P(X < 25) = 0.0939
As there are N = 2867 people in the data, so number of people expected to have age less than 25 is -
n = N x P(X < 25)
n = 2867 x 0.0939
n = 269.21
n = 270(approx)
Thus, 270 people should have age less than or equal to 25.
