Answers
The correct expression is \($(150 \cdot 1.15)^7$\) (Choice A).
The problem states that the painting's value increases by a factor of 1.15 each year. This means that the value at the end of each year is 1.15 times the value at the beginning of the year. Therefore, after one year, the value of the painting is\($150 \cdot 1.15 = 172.50$\).
To find the value after 7 years, we need to multiply the value of the painting each year by 1.15 a total of 7 times. This can be represented mathematically as \($(150 \cdot 1.15)^7$\). This expression is equal to the starting value of the painting, 150, multiplied by 1.15$ raised to the 7th power, which represents the 7 years of appreciation.
If we were to choose expression B, it would give an incorrect result because it uses a value of 1.1 instead of 1.15 to represent the yearly increase in value.
Expressions C and D are also incorrect because they are not taking into account the compounding effect of the yearly increase. Expression C adds the initial value and the total years together, and expression D adds the initial value to the yearly increase multiplied by 7, neither of which correctly reflects the exponential growth of the painting's value.

i need help with a and b
Answers
a. The linear expression of \(V(t)=3+0.5t\) and the time in which the volume became 20 ft³ is 34 sec.
b. It takes 34 seconds to completely fill the balloon.
What is volume?
Volume is defined as the the amount of space inside a body to holds something.
(a) Let V(t) be the volume of hydrogen in the balloon at time t (in seconds), and let t = 0 correspond to the initial time when the balloon has 3 ft of hydrogen. Since the hydrogen is being filled at a constant rate of 0.5 ft/s, we have:
V(t) = 3 + 0.5t
This is a linear function with a slope of 0.5, which represents the rate of change of the volume with respect to time.
(b) To find how long it takes to completely fill the balloon, we need to solve the equation V(t) = 20 for t:
3 + 0.5t = 20
Subtracting 3 from both sides, we get:
0.5t = 17
Dividing by 0.5, we get:
t = 34
Therefore, it takes 34 seconds to completely fill the balloon.

What is the exact value of sin pi/3?
Answers
The exact value of sin(pi/3) is √3. By definition, the sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse. Therefore, sin(pi/3) = √3/1 = √3.
The exact value of sin(pi/3) can be determined using trigonometric properties and identities.
First, we know that pi/3 is equivalent to 60 degrees. In a unit circle, the point corresponding to 60 degrees forms an equilateral triangle with the origin and the x-axis. This triangle has side lengths of 1, 1, and √3.
To find the sine of pi/3, we consider the side opposite the angle (pi/3) in the triangle. In this case, the opposite side has a length of √3. The hypotenuse of the triangle is 1, as it is the radius of the unit circle.

Which of the following points satisfies y < 3x - 6?

The point (2,-4) satisfies y < 3x - 6

y<3x-6
-4<3(2)-6
-4<6-6
-4<0
Now let’s substitute (1,0) into the inequality:
y<3x-6

Find the surface area of the cylinder. Use 3.14 for pi.
Answers
Answer:
527.52 ft²
Step-by-step explanation:
The surface area of a cylinder is:
\(\displaystyle{2\pi r^2 + 2\pi r h}\)
where r is radius and h is height.
From the attachment, we know that the radius (r) is 7 ft and the height is 5 ft. Therefore:
\(\displaystyle{\text{Surface Area} = 2 \cdot 3.14 \cdot (7)^2 + 2\cdot 3.14 \cdot 7 \cdot 5}\\\\\displaystyle{\text{Surface Area} = 6.28 \cdot 49 + 6.28 \cdot 35}\\\\\displaystyle{\text{Surface Area} = 307.72 + 219.80}\\\\\displaystyle{\text{Surface Area} = 527.52 \ \: \text{ft}^2}\)
Therefore, the surface area of the cylinder is 527.52 ft²
Suppose that a random sample of 50 bottles of a particular brand of cough medicine is selected and the alcohol content of each bottle measured. The sample mean alcohol content is 8.6 ml and the standard deviation is 2.99 ml. The standard deviation of the alcohol content is required, by law, to be less than 2.8 ml.A 90% confidence interval for the population variance of the alcohol content is( 6.60 ; 12.91 ).Thus, we can conclude with 90% confidence, thatSelect one:a.the average alcohol content for this brand of cough medicine is between 6.6 ml and 12.91 ml.b.between 6.6% and 12.91% of the possible values of the sample variance will meet the requirements of the law.c.the sample variance of the alcohol content is between 6.6 ml and 12.91 ml.d.the population variance for this brand of alcohol meets the requirements of the law 6.6% to 12.91% of the time.e.the population variance for this brand of cough medicine is between 6.6 ml and 12.91 ml.
