An exponential function can be represented by the below four situations.

An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance; and A total population is increasing by about 7.5% each year.

An exponential function is one in which the amount increases or decreases by being multiplied by a fraction or decimal.

In the first situation, 4/5 of the number is found per year; this means we multiply by 4/5.  This is exponential.

In the second situation, the number of miles increases by 38 per gallon of gas used.  This is adding 38, so it is not exponential.

In the third situation, the amount in the checking account is decreased by subtracting $25.75 for every month that passes; this is not exponential.

In the fourth situation, the number of toads increases by 7.5%; this is done by multiplying by 1.075 each time.  This is exponential.

Hence the answer is an exponential function can be represented by the above four situations.

The solution is y = -5

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Given data ,

Let the function be f ( x ) = y

And , y = x² + 2x - 8

So , f ( x ) = x² + 2x - 8

Substituting the value for x in the equation , we get

When x = -3

f ( -3 ) = ( -3 )² + 2( -3 ) - 8

         = 9 - 6 - 8

         = 9 - 14

f ( -3 ) = -5

When x = 1

f ( 1 ) = ( 1 )² + 2( 1 ) - 8

       = 1 + 2 - 8

       = 3 - 8

f ( 1 ) = -5

Mrs. Rowan's  , percent error is  40% .

In the question ,

it is given that ,

the time allotted by Mrs. Rowan to complete the exam = 30 minutes

the time that the last student took to complete the exam = 42 minutes

the percent error can be calculated using the formula

percent error = (time student take - time allotted) / (time allotted) × 100

Substituting the values of allotted time and time taken by the student from above , we get

percent error = (42 - 30)/30 × 100

= 12/30 × 100

= 0.4 × 100

= 40%

Therefore , Mrs. Rowan's percent error is  40% .

Answer: 40°

Step-by-step explanation:

First angle can be represented as x, second angle can be represented as y, and the third angle can be represented as z.

x + y + z = 180°

Since the first and second angles are equal, x = y, we can replace y with x.

x + x + z = 180°

The third angle is 2.5 times the first, which can be written as 2.5x.

x + x + 2.5x = 180 (now we solve for x)

4.5x = 180

x = 40°

Check:

40 + 40 + 40(2.5) = 180°

180°=180°

The percent of decrease is 63.16%

How to calculate the percentage of decrease?

First, we calculate the amount of decrease

= $3,800 - $1,400

= $2,400

Next we dividing the amount of decrease by original price (old price)

= $2,400 ÷ $3,800

= 0.6316

And then convert the result into a percentage by multiplying by 100%

= 0.6316 × 100%

= 63.16%

Thus, the percent of decrease is 63.16%

In the question:

The values are given as:

f(0)=6 and f(7)=27

To write a linear function.

Now, According to the question:

Write the equation of linear function:

y = mx + b

Substitute (0,6) and (7, 27) into y = mx + b:

6 = m x 0 + b

27 = m x 7 + b

Solve the equation:

6 = b

27 = 7m + b

Swap the sides :

b = 6

27 =7m +b

Substitute into one equation:

27 = 7m + 6

7m = 27 - 6

80 five-card hands (drawn from a standard deck) contain exactly two aces

Permutations and combinations are  ways of representing groups of objects by selecting them  and subsetting them into sets. It defines different ways of arranging a particular data group. When we choose data or objects from a particular group, it is called a permutation and the order in which they are presented is called a combination. Both concepts are very important in mathematics.

It's always helpful to try to visualize the problem and how to approach it.

Think of the card arrangements as an array of length 5 named A.

Lets get the total number of ways that 2 slots of the 5 can be selected (Number of possible arrangements of 2 elements in an array of size 5) in A. That's a simple combination. That is:

(5/2)

Now lets get the total number of ways the available Aces can be arranged at those 2 selected slots in A.

(4/2)

Multiplying both combinations given above gives us the number of ways 2 cards of a set of 4 cards can be placed at 5 slots:

(5/2)(4/2)

NOTE: This is not the numbers of 5-card hands that has exactly 2 Aces. This is the total number of arrangements of 2 Aces of the 4 in A.

We have yet to compute the number of arrangements of the remaining cards. We took out 4 cards (The Aces) of the 52 card deck so that leaves us with 48 remaining cards to be arranged at A and took 2 slots from A. So that gives us:

(48/3)

So the answer is:

(5/2)(4/2)(48/3) = 80 five-card hands (drawn from a standard deck) contain exactly two aces

The number of photos that Sam takes in the afternoon is 224.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

In this case, Sam is taking photos for the yearbook and she takes 140 photos in the morning and in the afternoon, she takes 60% more photos.

The photos taken in the afternoon will be:

Answer:

1. a) rectangle, circles.

1. b) circumference.

2. half.

3. 2πr² + 2πrh

4. See below.

Step-by-step explanation:

a) The net of a cylinder is made up of one rectangle and two circles.

b) The width of the rectangle in the net of a cylinder is equal to the circumference of the circle.

The radius of a circle is half the diameter.

[tex]\textsf{Circumference of a circle} = \pi d=2 \pi r[/tex]

Therefore, the formula for the surface area of a cylinder is:

[tex]\begin{aligned}\textsf{S.A. of a cylinder}&=\sf 2\;circles+1\;rectangle\\&=2 \pi r^2+2\pi rh\\&=2\pi r(r+h)\end{aligned}[/tex]

where r is the radius of the circle and h is the height of the cylinder.

Note: It appears from the question sheet that they wish you to use π=3.

Also, as you need to estimate the total surface area, round any decimals to their nearest whole number before carrying out any calculations.

Please note that the formula for Area of Rectangle quoted in the example question is incorrect when comparing it to the answer of question 1b.  In the formula, it says that the length is equal to the circumference of the circle, whereas in question 1b it states that the width of the rectangle is equal to the circumference.  Therefore, I have used the correct formula for the rectangle part of the cylinder:

Given:

Area of One Circle

[tex]\begin{aligned} \pi \times r^2&=3 \times (5)^2\\&=3 \times 25\\&=75\; \sf cm^2\end{aligned}[/tex]

Answer: 144

Step-by-step explanation:

When we go from 4 to 16, we add 12. Then, to get to 36, we add 20. Then, we add 28 to get 64, and finally 36 to get 100. The pattern looks like we add by 8 more every time, so next number is 100 + (36 + 8) or 144.

The sequence of squares of even nos. so the 8th term would be the square of 16 which is 256.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

The given sequence is 4, 16, 36, 64, 100...

This is a sequence of squares of even nos.

The first term is the square of 2 and the second term is the square of 4 hence the 8th term would be the square of 16 which is 16² = 256.
