The equation n = t * 1.029 represents the cost of new cars and trucks next year.

What is the percent increase?

The percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage. Mathematically, the formula is expressed as Percentage Increase = [(Final Value - Initial Value)/Initial Value] × 100.

The 2.9% increase in cost is represented by the factor of 1.029 (1 + 0.029). To calculate the cost of a car next year, we multiply this year's cost (t) by 1.029.

n = t * 1.029

Where n represents next year's cost and t represents this year's cost.

This equation can also be written as n = t(1 + 0.029) or n = t + 0.029t which shows the relationship between this year's cost and next year's cost.

Hence, The equation n = t * 1.029 represents the cost of new cars and trucks next year.

So the area of the pupil after entering the room is (π(r/2)^2) = (πr^2)/4 and the area of the pupil after entering the room is 4 times smaller than the area of the pupil before entering the room.

a. The area of a circle can be represented by the formula A = πr^2, where A is the area and r is the radius of the circle. The radius of the pupil can change depending on the amount of light entering the eye, so we can represent the radius as a variable, r. Therefore, the polynomial that represents the area of the pupil is A = πr^2.

b. The width of the iris, x, decreases from 4 millimeters to 2 millimeters when you enter a dark room. Since the iris controls the size of the pupil, we can assume that the radius of the pupil also decreases by half when the width of the iris decreases. Therefore, the area of the pupil after entering the room is (πr^2) / 4, where r is the radius of the pupil before entering the room.

So the area of the pupil after entering the room is (π(r/2)^2) = (πr^2)/4.

Therefore the area of the pupil after entering the room is 4 times smaller than the area of the pupil before entering the room.

1400 square feet

Step-by-step explanation:

The area of a rectangle is found by multiplying its length by its width. So the area of Jenny's garden, which is 28 feet by 50 feet, is:

28 x 50 = 1400 square feet

To use mental math, Jenny could use the distributive property of multiplication.

First, she could break down the 28 into 20 and 8, and 50 into 40 and 10.

Then, she could think 20 x 50 = 1000 and 8 x 10 = 80

Finally, she could add 1000 + 80 = 1080.

So, the area of the garden can also be found by breaking down one of the dimensions into smaller parts, multiply them and add the results.

Another way to use mental math is to think of it as a square with side length of 50 ft, and then think of it as 28 rectangles of 1 ft by 50 ft. The area is then 50 x 28 = 1400 sq ft.

The distance of Julie from the base of the tower is 72.2 feet.

From the top of a tower, John sees his friend Julie on the ground at an angle of depression of 49 degrees. The height of the tower is 83 feet.

Therefore, the distance of Julie from the base of the tower can be calculated as follows:

This situation forms a right angle triangle.

Hence, using trigonometric ratios,

tan 49° = opposite / adjacent

tan 49° = 83 / a

cross multiply

a tan 49° = 83

divide both sides by tan 49°

a = 83 / tan 49°

a = 83 / 1.15036840722

a = 72.1507996916

The issue is that the organizers of a tame fishing tournament think that the lake has a substantial population of large mouth bass, therefore they assumed that the spouses of these fish have modeled that is q to the right, with a mean of 2.3 and a standard deviation of 1.67. The first half of the inquiry is, therefore, why does the skewed model make sense in this situation? then what for this? The correct model, a skeeto, will provide the answer since it is reasonable to assume that the lake has a large number of little fish and few larger ones.

The following portion of the question asks you to clarify why you can't use the normal model to calculate the likelihood that a large mouth, but some randomly selected from the lake, weighs more than 2 pounds. So, in this case, the distribution is not normal and the precise distribution is not provided. Because of this, it is impossible to answer the third half of the question and establish the probability at this time. Each participant in the competition is said to capture 15 fish every day. Can we therefore calculate the likelihood that some 1 catches average more than 2 pounds? Okay, so this is where the response will be: The probability cannot be calculated because of the distribution  is q to the right and the sample size of 15 is not large enough to use the central limit theorem.

The next section of this question states that each of the 14 contenders has a catch limit of 15 fish. What then is the norm? The sample size's 14 to 15 point deviation from the mean weight of the 210 fish currently captured here. That is equivalent to 210 correct points. And so, this is the norm. this is a departure. Sorry, yeah, so the population's standard deviation will be the same as the mean in this case. This is the population based on standard deviation of sample size squared. There is a 1.67 standard deviation. This is the square root of 210.

No, it is not possible to form a right triangle with the sides as 15 cm, 8 cm, and 17 cm .

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides (legs) must equal the square of the longest side (the hypotenuse). In this case, 15^2 + 8^2 = 289 + 64 = 353, which is not equal to 17^2 = 289.

Answer: The original polynomial can be found by using the Remainder Theorem. According to the theorem, if a polynomial is divided by (x+4), the remainder is equal to the value of the polynomial when x is replaced by -4.

So, if the remainder is -4, we can write:

f(x) = (x^2 - x + 8)(x + 4) + (-4)

f(x) = x^3 - x^2 + 8x + 4x^2 - 4x + 32 + (-4)

f(x) = x^3 + 3x^2 + 4x + 28

So, the original polynomial is f(x) = x^3 + 3x^2 + 4x + 28.
