What is the equation of the midline for the function y = 2sin(x - π) + 3
Answers
The equation of the midline for the function 2sin (x - π) + 3 is y = 3.
What is the Midline of a Function?The midline of a function is the line horizontal to the minimum value and maximum value of the function.
Given function is 2sin (x - π) + 3.
We know the trigonometric formula,
sin (A - B) = sin A cos B - cos A sin B
sin (x - π) = sin x cos π - cos x sin π
= (sin x × -1) - (cos x × 0) [Since cos π = -1 and sin π = 0]
= -sin x
So, 2sin (x - π) + 3 = -2sinx + 3
Now, we know that,
-1 ≤ sin x ≤ 1
Multiplying whole sides by -2,
2 ≥ -2sin x ≥ -2
[since the inequality sign changes when negative is multiplied or divided]
Adding 3 throughout,
5 ≥ -2sin x + 3 ≥ 1
Maximum value is 5 and minimum value is 1.
Midline value = (5 + 1) / 2 = 3
So the equation of the midline is y = 3.
Hence the equation of midline is y = 3.

You have been hired by a museum to make a scale drawing poster of a painting to sell at the gift shop. The painting is 65in high by 105in wide. You are asked to use a 1in = 5in scale. What will the dimensions of your poster be? (2 points)
Answers
[scale]=[poster]/[painting]
[poster]=[painting]*[scale]
scale=1/5
then
for high = 65 in the painting
[poster]=[painting]*[scale]-----------> [65]*[1/5]-----> 65/5-------> 13 in
for wide = 105 in the painting
[poster]=[painting]*[scale]-----------> [105]*[1/5]-----> 105/5-------> 21 in

Consider the following pair of equations:
y = x + 4
y = −2x − 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answers
y = x + 4
y = -2x - 2
To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4
x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2
now use the value for x to find y by putting into either equation.
y = x + 4
y = (-2) + 4
y = 2
solution is: (-2, 2)
The following tables each show the amount of money, in dollars, in four different bank accounts over time.
Which table best represents an exponential relationship?
Answers
it seems that the first one is the answer.
1210/1100=1.1
1331/1210=1.1
Answer with explanation:
The general exponential relationship is
→[tex]y=a*b^x {\text{or}}, x=a*b^y[/tex]
The four tables which is given here, all of them represents exponential relationship because with increase in value of y ,x value increases or vice versa.
The exponential function can be either strictly increasing or strictly decreasing.
Table 1
[tex]\frac{1210}{1100}=\frac{1331}{1210}=\frac{1464.10}{1331}=\frac{1610.51}{1464.10}=1.1[/tex]
In Table 2, Table 3,and table 4, the rate of increase is not constant, it varies that is for different two consecutive y, values their ratio is not constant.
Table 1, best represents the exponential relationship, represented as
[tex]y=1100*(1.1)^x[/tex]
Where, x=1,2,3,4,5

LIMITED TIME
Answers
So 't' is the independent variable, and 'f(t)' is the dependent variable.
The wording of the second option, the second to last, and the last is all correct. The questions says "let 't' be the time in years after 2000", so if 't' were say 5, this would mean 5 years after 2000 or 2005. The question also states "let f(t) be the amount of garbage", so the result must be the amount of garbage.
So now we just need to confirm if the calculations were done correctly.
Option 2:
[tex]\sf f(2)=1233[/tex]
This is the same thing as saying if you plug in 2 for 't', you will get 1233, let's try it:
[tex]\sf f(t)=1200\cdot (1.05)^t[/tex]
Plug in 2 for 't':
[tex]\sf f(2)=1200\cdot (1.05)^2[/tex]
Simplify the exponent:
[tex]\sf f(2)=1200\cdot (1.1025)[/tex]
Multiply:
[tex]\sf f(2)=1323[/tex]
So option 2 is incorrect, and we see also that option 6 is correct. Now for the last one:
Option 7:
[tex]\sf f(4)=1458.6[/tex]
This is the same thing as saying if you plug in 4 for 't', you will get 1458.6, let's try it:
[tex]\sf f(t)=1200\cdot (1.05)^t[/tex]
Plug in 4 for 't':
[tex]\sf f(4)=1200\cdot (1.05)^4[/tex]
Simplify the exponent:
[tex]\sf f(4)=1200\cdot (1.21550625)[/tex]
Multiply:
[tex]\sf f(4)\approx 1458.6[/tex]
So the last option is also correct.
So your answers are options 3, 4, 6 and 7.

Suppose that 24% of people own dogs. if you pick two people at random, what is the probability that they both own a dog?
Answers
To find the probability that both people randomly picked own a dog, we multiply the probability of one person owning a dog (24%) by itself, resulting in a 5.76% chance that both own a dog.
The question is asking us to calculate the probability that two randomly selected people both own a dog, given that 24% of people own dogs. Since the events (each person owning a dog) are independent, the probability of both events happening is the product of their individual probabilities.
Let's denote the probability of one person owning a dog as P(dog) = 0.24. Then, for two independent people, the probability that both own a dog is [tex]P(dog) \times\ P(dog) = 0.24 \times\ 0.24 = 0.0576.[/tex]
So, the probability that both people picked at random own a dog is 5.76%.

First question:
Your total restaurant bill is the items you have purchased plus the sales tax and plus the tip (if there’s any). Sales tax is added to your purchase because this is tax imposed to the consumer and not to the buyer. The buyer is only required to collect this tax from the buyer.
Second question:
A check is a financial instrument wherein the bank is required to pay when presented or encashed to them. You just have to make sure that you have account balance to that certain bank.
Third question:
The way of payment not any more common in the most modern economies is the bartering. Both credit cards and cash are the most common way of paying for your purchases.
Answer:
1. the items purchased plus sales tax and tip.
2. a promissory note (I.O.U.)

The conjugate of the expression 4 - (x + 5) is formed by changing the minus sign to a plus sign, resulting in the expression 4 + x + 5, which corresponds to option D.
Explanation:The conjugate of a binomial expression like 4 - (x + 5) is obtained by changing the sign between the two terms. Hence, the conjugate of this expression would change the subtracted term (-x - 5) to its additive inverse, which is (+x + 5). Therefore, the correct choice is 4 + x + 5, which is option D.

4.Krissa drew a circle with a radius of 4 inches.
Fill in the blanks.
The area of the circle is _______ square inches and the circumference is _______ inches.
64π, 16π
16π, 8π
16π, 64π
8π, 16π
Answers
Explanation:
1) To calculate the area use the formula:
Area = π (radius)^2
radius = 4 in => area = π (4 in)^2 = 16π in^2
2) To compute the circumference use the formula:
Circumference = 2π(radius)
=> Circumference = 2π (4 in) = 8π in.
To calculate the area of a circle, use the formula A = πr², where r is the radius. For this specific circle with a radius of 4 inches, the area is 16π square inches, and the circumference formula is C = 2πr, resulting in a circumference of 8π inches.
To find the area of a circle: A = πr². Substituting the given radius of 4 inches, we get Area = π(4)² = 16π square inches. The circumference of a circle is C = 2πr. Substituting the radius, we get C = 2π(4) = 8π inches.
