Dilation – stretching or compressing the graph of a function Move the slider on the graph to graph each function and describe the transformation. y=2^x. vertical stretch or vertical compression?
Answer: The first answer is A. vertical stretch
Step-by-step explanation: The next one is B. vertical compression
The graph of the function y = 2^x represents a vertical stretch.
Explanation:The given function is y = 2^x. To determine if it represents a vertical stretch or vertical compression, we need to examine the value of the coefficient in front of the exponent which is 2. If the coefficient is greater than 1, it represents a vertical stretch. If the coefficient is between 0 and 1, it represents a vertical compression. In this case, the coefficient is 2 which is greater than 1, therefore the graph of the function y = 2^x represents a vertical stretch.

Step-by-step explanation:
Sue either travels by bus or walks when she visits the shops. The probability that she catches the bus to the shops is 0.4 . The probability that she catches the bus from the shop is 0.7 . Show the probability that sue walks at least one way is 0.72
Answer: P(A∪B)=0.72. The answer is provided below.
Step-by-step explanation:
Sue travels by bus or walks whenever she goes to the shops.
Probability of (catching the bus to shop ), P(A)= 0.4
Probability of (catching the bus from the shop ), P(B) = 0.7
Both of the events A and B are independent events.
Therefore, P(A∩B) = 0.4 × 0.7
= 0.28
Probability that Sue walks one way will be = 1 - P(A∩B)
= 1 - 0.28
= 0.72
Hence, the probability that Sue will walk at one way is 0.72
Final answer:
To find the probability that Sue walks at least one way, we calculate the complement of the probability of her taking the bus both ways. The probability of Sue taking the bus to and from the shops is 0.4 times 0.7, which equals 0.28. The probability that she walks at least one way is then 1 minus 0.28, giving us 0.72.
Explanation:
The question involves calculating the probability that Sue walks at least one way to or from the shops, given the probabilities of her taking the bus. We are given that the probability of Sue catching the bus to the shops is 0.4 and from the shops is 0.7. To find the probability of walking at least one way, we consider the complement of the event that she takes the bus both ways.
Firstly, we calculate the probability that she takes the bus both ways:
P(Bus to and from shops) = P(Bus to shops) × P(Bus from shops) = 0.4 × 0.7 = 0.28
Now, the probability that she doesn't take the bus both ways (which means she walks at least one way) is the complement of the above event:
P(Walk at least one way) = 1 - P(Bus both ways) = 1 - 0.28 = 0.72
Therefore, the probability that Sue walks at least one way is indeed 0.72, as required to show.

What is the relationship between the sine and cosine of the complementary angles in this diagram?
Drag and drop the answers into the boxes to correctly complete the statements.
Both cos(17°) and sin(x°) can be represented by the ratio-------- . The angles measuring 17° and x° are complementary angles. This means x° + 17° =--------- . Therefore, x = -----. Since cos(17°)=sin(x°) , this also shows that cos(17°)=sin(------ )°.
these are the possibilities for the blanks:
a/b
a/c
b/c
90 degrees
180 degrees
90-17
180-17
Answer:
Both cos(17°) and sin(x°) can be represented by the ratio a/c. The angles measuring 17° and x° are complementary angles. This means x° + 17° = 90°
Therefore, x = 90-17 Since cos(17°)=sin(x°), this also shows that cos(17°)=sin( 90-17)°
this is the correct answer.
The required possibilities for the blanks as b/c, 90 degrees, (90° - 17°), and (90° - 17°). Where 17° and x° are complementary angles
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles.
In the given question,
Both sin(17°) and cos(x°) can be represented by ratio b/c because values of sin(17) and cos(x) are b/c.
Since 17° and x° are complementary angles, hence the value of x will be = 73 degrees. And sin(17°) = cos(x°), therefore sin(17°) = cos(90° - 17°).
Therefore, the required possibilities for the blanks as b/c, 90 degrees, (90° - 17°), and (90° - 17°).

A radioactive element decays at a rate of 5% annually. There are 40 grams of the substance present. • How much of the substance remains after 30 years (to the nearest tenth)? • When will the amount of the substance drop to below 20 grams (to the nearest year)?
Answer:
8.6 grams of the substance remains after 30 years.
The amount of the substance will drop to below 20 grams in 14 years.
Step-by-step explanation:
The amount of the substance after t years is given by the following equation:
[tex]A(t) = A(0)(1-r)^{t}[/tex]
In which A(0) is the initial amount and r is the yearly decay rate.
A radioactive element decays at a rate of 5% annually. There are 40 grams of the substance present.
This means, respectively, that [tex]r = 0.05, A(0) = 40[/tex]
So
[tex]A(t) = A(0)(1-r)^{t}[/tex]
[tex]A(t) = 40(0.95)^{t}[/tex]
How much of the substance remains after 30 years (to the nearest tenth)?
This is A(30).
[tex]A(30) = 40(0.95)^{30} = 8.6[/tex]
8.6 grams of the substance remains after 30 years
When will the amount of the substance drop to below 20 grams (to the nearest year)?
This is t when A(t) = 20. So
[tex]A(t) = 40(0.95)^{t}[/tex]
[tex]20 = 40(0.95)^{t}[/tex]
[tex](0.95)^{t} = \frac{20}{40}[/tex]
[tex](0.95)^{t} = 0.5[/tex]
[tex]\log{(0.95)^{t}} = \log{0.5}[/tex]
[tex]t\log{0.95} = \log{0.5}[/tex]
[tex]t = \frac{\log{0.5}}{\log{0.95}}[/tex]
[tex]t = 13.51[/tex]
Rounding to the nearest year
The amount of the substance will drop to below 20 grams in 14 years.
1) The amount of substance that will remain after 30 years is; A(30) = 8.6 g
2) The time when the amount of the substance drop to below 20 grams is; t < 14 years
To calculate the amount of substance that remains after t number of years of decay is;A(t) = A_o(e^(-rt))
Where;
A_o is initial amount
r is rate of decay
t is time in years
A(t) is amount left after t years
We are given;
A_o = 40 g
r = 5% = 0.05
1) To find the amount of substance left after 30 years is;
A(30) = 40 × e^(-0.05 × 30)
A(30) = 8.925 g
Approximating to the nearest tenth gives;
A(30) = 8.9 g
2) To find the time when the amount of the substance drop to below 20 grams.
20 > 40 × e^(-0.05 × t)
20/40 > e^(-0.05 × t)
-0.05t < In 0.5
t < (In 0.5)/-0.05
t < 13.86 years
Approximating to the nearest year gives;
t < 14 years

what is 8.0622577483 rounded to nearest tenth?
Answer:
it is 8.1
Step-by-step explanation:
if u see u round over or add 1 to the number if the number that is next to the number ur rounding is 5 or higher. and u do nothing when it is less than 5.
the tenth place is where the the zero is 0.0
and the number after is 6, so it is greater than 5, so it increases
Answer:8.1
Step-by-step explanation:
To round to the nearest tenth (the first decimal place), look at the number in the hundredth (the second decimal place) and round up or down. Since the number in the hundredths is a six, you round up.
You round down if the number is less than 5 and up if it is equal to or greater than 5.
State if each angle is an inscribed angle. If it is, name the angle and the intercepted arc.
Answer:
No, there are no inscribed angle in this diagram; Option D
Step-by-step explanation:
~ Let us apply process of elimination to solve this problem ~
Option 1. This first example states firstly that m∠SRT is an inscribed angle. That is not true, by definition an inscribed angle is an angle created by two chords that share a common endpoint. Neither RS nor RT are chords, in fact they each are radii, creating a central angle instead.
Option 2. m∠RST is not created by two chords, instead by arc ST and radii RS ⇒ and I believe I am not familiar with what angle it is reffered to, if at all it is named.
Option 3. As stated before, ∠SRT is not an inscribed angle; by definition an inscribed angle is an angle created by two chords that share a common endpoint, and neither RS nor RT are chords.
Option 4. Through elimination, Option D is the only possible answer left: Answer: No, there are no inscribed angle in this diagram
A survey found that 6 out of 8 students own a pet. If there are 480 students in a school, what is a reasonable prediction for the number of students who do NOT own a pet?
Answer: 120

John will paint the four walls of his rectangular basement. The basement measures 10 feet long, 13 feet wide, and 8 feet high and has no windows. The door into the room measures 3 feet by 7 and will not be painted. How many square feet of wall will John paint?
Answer:
D. 1,019 square feet
Step-by-step explanation:
10x13x8 - 3x7
John will need to paint 347 square feet of wall in his rectangular basement after subtracting the area of the door that will not be painted.
John will paint the four walls of his rectangular basement. To calculate how many square feet of wall he will need to paint, we must first determine the total area of the walls and then subtract the area of the door.
The total wall area is calculated as follows:
Two walls are 10 feet long and 8 feet high, giving 2 x (10 x 8) = 160 square feet.
The other two walls are 13 feet wide and 8 feet high, giving 2 x (13 x 8) = 208 square feet.
So, the total wall area is 160 + 208 = 368 square feet.
The door measures 3 feet by 7 feet, which equals 21 square feet.
To find the area John will paint, we subtract the area of the door from the total wall area:
368 square feet - 21 square feet = 347 square feet
Therefore, John will need to paint 347 square feet of wall.

An insurance company has a merit rating system for customers who have not filed a claim in the previous year. For each year that a customer does not file a claim, their rate is reduced by 10%, and a credit of $5 is awarded. If a customer did not file a claim in the nth year, which equation shows the customer's rate in the (n + 1)th year as a function of their rate in the nth year?
A.
f(n + 1) = f(n) - 0.1f(n) - 5
B.
f(n + 1) = f(n) - 0.1f(n) + 5
C.
f(n + 1) = f(n) + 0.1f(n) + 5
D.
f(n + 1) = f(n) - 0.1f(n) - 10
Answer: B
Step-by-step explanation:
For each year that a customer does not file a claim, their rate is reduced by 10%,
This means that every year that passes, we have a subtraction of a 10% (or 0.1 in decimal form)
And also for each yearm we have a credit of $5 awarded, this means that we have an addition of $5.
Then the relation is:
f(n + 1) = f(n) - 0.10*f(n) + $5
The correct option is B
