This exponential function represents growth at a rate of 26.2% per unit increase in x.

This represents growth at a rate of 26.2% per unit increase in x.

This is an exponential function, so it will represent either growth or decay. To determine whether it is growth or decay and what rate it is, we need to look at the coefficient of the exponential term, which in this case is 1.262. Since this is larger than 1, the function is growing, and the rate of increase is equal to the coefficient minus 1, which is 26.2%.

This exponential function represents growth at a rate of 26.2% per unit increase in x.

By using The Pythagoras theorem, the expression g = f/2 represents the relationship between g and f if j = h and k = m option (A), i.e. g = 1/2  is correct.

Pythagoras theorem:

The Pythagorean Theorem, also known as the Pythagorean Theorem, describes the relationship between the three sides of a right triangle. According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the other two sides of the triangle. If AB and AC are the sides and BC is the hypotenuse of the triangle then BC2 = AB2 + AC2 .where AB is the base, AC is the height or altitude and BC is the hypotenuse.

The area of ​​the square formed by the longest sides (hypotenuses) of right-angled triangles is equal to the sum of the areas. The number of squares formed by the other two sides of a right triangle. In a right triangle, the formula for the Pythagorean theorem is expressed as:

c² = a² + b²

where

'c' = hypotenuse of a right triangle

'a' and 'b' are the other two legs.

In the question:

It is given that:

If j = h and k = m

From the given question, C is a right-angle triangle as j = h and k = m

From the definition of the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides

         h² +k²= g²

From the triangle ΔABC

(j + h)² +(m + h)² = f²

⇒ (h + h)² +(k+ k)² = f²

⇒ (2h)² +(2k)²= f²

⇒ 4h²+ 4k² = f²

⇒ 4(h²+k²) = f²

⇒ 4×g² = f²

⇒ (2g)² = f²

⇒ 2g = f

⇒ g = f/2

Thus, the expression g = f/2 represents the relationship between g and f if j = h and k = m option (A) is correct.

The three quartiles is the value of Q₂ [Median] is 73 (on the 7th value), The value of Q₁ is 70 (the 3.5th value), The value of Q₃ is 77 (is the 10.5th value). and Interquartile range = Q₃ - Q₁ = 77 - 70 = 7

A quartile is a particular kind of quantile that splits the total number of data points into four roughly equal portions, or quarters. Quartiles are a type of order statistic since they require the data to be arranged from smallest to largest in order to be computed.

The median of the data set is the number in the midpoint between the smallest number (minimum) and the first quartile (Q1).

The median of a data set is known as the second quartile (Q2).

The median value and the highest value (maximum) in the data set are the two values that make up the third quartile (Q3).

To find the quartiles, first, we need to put the data in ascending order.

65,  68,  70,  70,  71,  72,  73,  74,  75,  77,  77,  78,  80

The value of Q₂ [Median] is on the 7th value, which is 73

The value of Q₁, the lower quartile, is the 3.5th value [(3rd value+4th value)/2] , which is 70

The value of Q₃, the upper quartile, is the 10.5th[(10th value+11th value)/2]  value, which is 77

and

Interquartile range = Q₃ - Q₁ = 77 - 70 = 7.

Answer:

The length of the short side was 12 and the length of the long side was 32

Step-by-step explanation:

We will say that the length is the shorter side, and be using l as the variable, and that width is the longer side, and be using w as the variable. The first two equations we have are:

w = l + 20

And

2(2l + 3w) = 240

We will start with the second equation, then substitute in the first equation for w. We have:

4l + 6w = 240

Divide both sides by 2:

2l + 3w = 120

Then, we substitute in l + 20 for w, giving us:

2l + 3l + 60 = 120

Subtract 60 from both sides and combine like terms:

5l = 60

l = 12

So, the original length was 12, now substituting this into our first equation gives us:

w = 12 + 20 = 32

So the original width was 32. So, the length of the short side was 12 and the length of the long side was 32.

Prime number - 17

Square number - 16

Step-by-step explanation:

Ok, so a prime number is a number with no factors other than 1 and the number itself.

14 = 2 x 7

15 = 3 x 5

16 = 4 x 4

17 = 1 x 17

18 = 3 x 6

So, every number here except 17, has three or more factors,.

So, the prime number here is 17.

If you look at 16, you see that 16 = 4 x 4

A square number means that it has a whole number, which when multiplied to itself, gets you that number.

Let ww represent the number of hours washing cars, and tt represent the number of hours tutoring.

The inequality representing the total number of hours Arianna must work between both jobs is:

This inequality states that the number of hours spent washing cars plus the number of hours spent tutoring must be greater than or equal to 10 hours. This represents all possible combinations of hours washing cars and hours tutoring that Arianna can work in a given week while meeting the requirement that she must work no less than 10 hours altogether between both jobs.

One is a unique number as it is only a positive integer that is neither prime nor composite.

If the numeral is a positive integer and there are no duplicate digits, it will be considered unique. The fact that one is the only positive integer that is neither prime nor composite makes it a unique number. It is the only positive integer that can be divided by each other and itself. As a result, only one can be regarded as the lowest common denominator among all other integers.

Given that it is the identity element for multiplication, every integer multiplied by one equals the original number. Additionally, it is the additive identity element, which means that any integer plus one equals itself. Every number may be stated as a power of one, which is the foundation of the number system.

With 20 counselors, there should be 250 boys at Laura's summer camp.

To determine how many boys should be at camp with 20 counselors, we can use the proportion of boys to counselors that existed at the camp when there were 200 boys and 16 counselors.

The proportion of boys to counselors when there were 200 boys and 16 counselors is 200/16 = 12.5 boys per counselor.

If we want to know how many boys should be at camp with 20 counselors, we can use this proportion and the number of counselors we have (20) to calculate the number of boys.

To calculate this, we can use the following formula:

Number of boys = (Proportion of boys to counselors) x (Number of counselors)

So for 20 counselors, the number of boys should be:

12.5 x 20 = 250 boys

Median is 55

P :Q: R :S :average of 45 :50: 55 :65

The number of pupils within every section needs to be as low as possible 

R is a mean

P differs by 1: 10 from the mean.

Q is 1.5 away from the mean.

The zeros to the right of the decimal point that are not just placeholders are significant. These significant zeros are to the right of any significant non-zero digits. The zeros to the left of the 20.00 cm decimal point are also significant, as they are among the significant digits. If a decimal point is present, all digits from the first non-zero digit (to the right) are significant.
