what is the multiplicative rate of change of the function described in the table ?
Answers
Hence, the multiplicative Rate of change is:
5
Step-by-step explanation:The multiplicative Rate of change refers to the fixed constant which when multiplied to the output will lead to increase/decrease in the next output value.
We have the table of values as:
x y
-1 1/10
0 1/2
1 5/2
2 25/2
3 125/2
Hence, we see that when 5 is multiplied to the output value we obtain the next output value.
i.e.
1/10×5=1/2
1/2×5=5/2
5/2×5=25/2
25/2×5=125/2
Hence, the multiplicative Rate of change is:

Label the sides as shown in the image attachment.
P = horizontal leg (opposite of angle x; adajcent to angle y)
Q = vertical leg (opposite of angle y; adajcent to angle x)
R = hypotenuse (longest side; always opposite the 90 degree angle)
Use the definitions of sine and cosine to say...
sin(Angle) = opposite/hypotenuse
sin(x) = P/R
and
cos(angle) = adjacent/hypotenuse
cos(y) = P/R
Notice how sin(x) = cos(y). This is true any time x+y = 90 which is the case here (x and y are complementary angles). A more specific example is sin(30) = cos(60) which are both equal to 1/2 or 0.5
Since sin(x) = cos(y), this means sin(x)/cos(y) = 1 as any expression divided by itself is equal to 1. Keep in mind that cos(y) cannot equal zero.
This is why choice D is the final answer.
side note: something like cos(x)/sin(y) or sin(y)/cos(x) or similar are all equal to 1 as long as x+y = 90

m < B = 55....so < K = 55 also
m < L = 25.....so < C = 25 also
so we need the measure of < J....and < A
interior angles of a triangle add up to 180 degrees
< J + < K + < L = 180
< J + 55 + 25 = 180

Biologists have proposed a cubic polynomial to model the length l of alaskan rockfish at age a:l = 0.0155a3 − 0.372a2 + 3.95a + 1.21, where l is measured in inches and a is in years. (a) (2 pts) calculate dl da a=12 (b) (2 pts) interpret your answer.
Answers
dl/da = 3(0.0155)a² - 2(0.372)a + 3.95
Substituting the known value, a = 12
dl/da = (3)(0.0155)(12)² - 2(0.372)(12) + 3.95
Simplify,
dl/da = 1.718
(b) The answer in a tells us that the length of the alaskan rockfish will change at a rate of 1.718 inches/year when it is already 12 years old.
To calculate dl/da when a=12, find the derivative of the cubic polynomial and substitute a=12. The rate of change of the length is approximately 1.682 inches per year.
Explanation:To calculate dl/da when a=12, we need to find the derivative of the given cubic polynomial with respect to a. The derivative of l with respect to a can be found by taking the derivative of each term separately and then simplifying:
Find the derivative of 0.0155a^3: 3 * 0.0155 * a^2 = 0.0465a^2 Find the derivative of -0.372a^2: 2 * -0.372 * a = -0.744a Find the derivative of 3.95a: 3.95 Find the derivative of 1.21: 0Now substitute a=12 into the derivatives we found:
0.0465(12)^2 = 6.66-0.744(12) = -8.9283.950So, dl/da when a=12 is approximately 0.0465(12)^2 - 0.744(12) + 3.95 = 6.66 - 8.928 + 3.95 = 1.682.
Interpretation: The value dl/da represents the rate of change of the length of the alaskan rockfish with respect to its age. In this case, when the rockfish is 12 years old, its length is changing at a rate of approximately 1.682 inches per year.

Deon drove 408 miles using 16 gallons of gas. At this rate, how many miles would he drive using 11 gallons of gas?
Answers
By setting up a ratio based on the known miles per gallon, we can determine that Deon would be able to drive 281.5 miles using 11 gallons of gas.
Explanation:This problem can be solved by setting up a proportion to find out how many miles Deon would drive using 11 gallons of gas. First, we know that Deon can drive 408 miles with 16 gallons of gas. This forms a ratio of 408/16 which simplifies to 25.5. This means Deon can drive 25.5 miles for every gallon of gas. Using this, we can determine how far he would travel with 11 gallons by multiplying the miles per gallon (25.5) by 11.
Therefore, Deon would drive 281.5 miles using 11 gallons of gas.

The phones at Century Cellphones vary in price depending upon demand. The average phone has a built in camera and costs x dollars. Phones with both a camera and an MP3 player are 35 dollars less than twice the cost of the phones with just the camera. Phones without any features are 100 dollars less than the cost of the phone with just the camera. Purchasing all three would cost at least $525.
a) Determine the inequality that represents this situation.
b) How much does the phone with just the camera cost?
Answers
a. let us say that:
a = cost of phones with camera
b = cost of phones with camera and mp3
c = cost of phones without any features
b = 2 a – 35
c = a – 100
a + b + c = 525
b > a > c
b. We are given three equations with three unknowns. So we can solve the problem.
a + (2 a – 35) + (a – 100) = 525
a + 2 a – 35 + a – 100 = 525
4 a – 135 = 525
4 a = 660
a = $165
a) According to the problem, purchasing all three phones would cost at least $525, which leads us to the inequality:
[tex]4x - 135 \geq 525[/tex]
b) The cost of the phone with just a camera is at least $165.
a) Setting Up the Inequality
Let’s define the variables based on the information given:
Let [tex]x[/tex] be the cost of the phone with just a camera. Then, the cost of the phone with both a camera and an MP3 player is given as:[tex]y = 2x - 35[/tex] The cost of the phone without any features is:
[tex]z = x - 100[/tex]
Now, the total cost of buying all three types of phones can be expressed as:
[tex]x + y + z[/tex]
Substituting the expressions for [tex]y[/tex] and [tex]z[/tex], we get:
[tex]x + (2x - 35) + (x - 100)[/tex]
This simplifies to:
[tex]4x - 135[/tex]
b) Finding the Cost of the Phone with Just the Camera
To find out the value of [tex]x[/tex], we can solve the inequality:
[tex]4x - 135 \geq 525[/tex]
Adding 135 to both sides gives:
[tex]4x \geq 660[/tex]
Now, dividing both sides by 4:
[tex]x \geq 165[/tex]

Last year, Bill opened an investment account with $6800 . At the end of the year, the amount in the account had increased by 24.5% . How much is this increase in dollars? How much money was in his account at the end of last year?
Answers
Bill's investment increased by $1666 over the year, which is 24.5% of the original $6800. At the end of the year, the total amount of money in the account was $8466.
Explanation:To determine the increase in dollars due to the investment growth of 24.5%, we would calculate 24.5% of $6800. We can use the formula increase = principal × (rate/100), where principal is the starting amount and rate is the percentage increase.
So, increase = $6800 × (24.5/100) = $6800 × 0.245 = $1666. This means that the increase in dollars is $1666.
Next, to find out how much money was in his account at the end of last year, we add this increase to the original investment: total amount = original amount + increase = $6800 + $1666 = $8466. Therefore, the total amount in the account at the end of the year was $8466.

Answers
The correct answer is option C g > 5.
To solve the inequality, we need to isolate the variable g. Here are the steps:
Add 6 to both sides of the inequality to isolate g.
The inequality now becomes: g - 6 + 6 > -1 + 6
Simplify both sides: g > 5
The solution to the inequality is g > 5.

complete the solution of the equation. Find the value of y when x equals -4
x + 3y = 14
Answers
When x equals -4, the value of y is 6 by substituting -4 into the equation x + 3y = 14 and solving for y.
Explanation:To complete the solution of the equation and find the value of y when x equals -4, simply substitute -4 for x into the equation x + 3y = 14. The steps are as follows:
Start with the equation: x + 3y = 14.Substitute -4 for x: (-4) + 3y = 14.Solve for y: 3y = 14 + 4.Simplify: 3y = 18.Divide both sides by 3: y = 18 / 3.Find the value of y: y = 6.Therefore, when x equals -4, the value of y is 6.
you find a fossilized animal footprint in montana. One footprint is round and has a diameter of 42cm. what is the are of the footprint?
Answers
To find the area of a round footprint with a diameter of 42 cm, you use the formula for the area of a circle, A = πr². The radius is 21 cm, so the area is approximately 1382.74 cm².
To find the area of a round footprint, you use the formula for the area of a circle, which is πr², where r is the radius of the circle.
First, find the radius by dividing the diameter by 2. In this case, 42 cm / 2 = 21 cm.Next, use the area formula: area = π x (radius)². So, area = π x (21 cm)².Calculate the result: area = π x 441 cm².Using the approximation π ≈ 3.14, the area ≈ 3.14 x 441 cm².The final area ≈ 1382.74 cm².Therefore, the area of the fossilized footprint is approximately 1382.74 cm².
