The dwarf planet Makemake completes one orbit around the Sun every 310 years. Which of the following functions r models the number of orbits of Makemake in t years?
Answer:
3rd option, r(t) = 310t
Step-by-step explanation:
310 years is like the slope so you multiple it by the amount of years
example: in 2 years it would make 620 orbits since 310(2) = 620
In a survey of 900 students in a school, it was found that 600 students liked tea, 500 liked coffee, and 125 did not like both drinks.
(i) Draw a Venn-diagram to illustrate the above information.
(ii) Find the number of students who like both drinks.
(iii) Find the number of students who like one of these drinks only.
A) The number of students who like both drinks is 325.
B) The number of students who like one of these drinks only. 275
What is venn diagram?A Venn diagram is used to visually represent the differences and the similarities between two concepts.
Total students= 900
students like tea=600
students like coffee=500
Students did not like both drinks=125
Students who both or any one of the drinks= 900-125=725
Now,
students like both drinks= 600+500-725
= 325
Hence, the number of students who like both drinks is 325.

Answer:
the 4th option because 24 months times the amount plus the 39.99 to set up would get you a final answer
Answer:
39.99/24c = 351.75
24c + 39.99 = 351.75
Where c is the cost to set up an account
Step-by-step explanation:
Knowing that it given:
What is the cost(c) month for using the service for 24 months?
That means "Cost = c"
That leads us to the answer:
"Where c is the cost to set up an account"
We also know that we are finding for the 24 months thus 24c.
That leads us to
24c + 39.99 = 351.75 and 39.99/24c = 351.75
Hence, the answers are:
39.99/24c = 351.75
24c + 39.99 = 351.75
Where c is the cost to set up an account

Answer:
The exact solution is:
x = the quantity of 3 plus or minus the square root of 37 all over 2
Step-by-step explanation:
We are asked to find the exact solution of the polynomial equation which is given by:
[tex]x^2 - 3x - 7 = 0[/tex]
We know that the solution of the equation are the possible value of x which is obtained on solving the equation and hence satisfy the equation.
Now, on solving the quadratic equation i.e. degree 2 polynomial equation using the quadratic formula:
That is any polynomial equation of the type:
[tex]ax^2+bx+c=0[/tex]
is solved by using the formula:
[tex]x=\frac{-b±\sqrt{x} b^2-4ac}{2a}[/tex]
Here we have:
a=1, b=-3 and c=-7.
Hence, the solution of the equation is:
[tex]x=\frac{-(-3)±\sqrt{(-3)^2-4*(-7)*1} }{2*1}[/tex]
[tex]x=\frac{3±\sqrt{9+28} }{2}[/tex]

27 Keane drives his car 180 miles from his home in Bristol to Liverpool. He leaves his home at 09 30 and arrives in Liverpool at 12 42. Work out the average speed of Keane’s journey in mph.
The average speed of Keane’s journey in mph is 56.25 mph (miles per hour)
Calculating Average speedFrom the question, we are to determine Keane's average speed
Average speed is given by the formula,
Average speed = Distance / Time
Distance travelled = 180 miles
Now, we will calculate the time spent
From the given information,
He leaves his home at 09:30 and arrives in Liverpool at 12:42
09:30 to 12:42 is 3 hours 12 minutes
∴ Time = 3 hours 12 minutes = 3 + (12/60) hours = 3.2 hours
Thus,
Average speed = 180 / 3.2
Average speed = 56.25 mph (miles per hour)
Hence, the average speed of Keane’s journey in mph is 56.25 mph (miles per hour)

The family decides to take a new route, which they estimate will be 125% of the distance when traveling on the highway. There are approximately 48.28 kilometers in 30 miles. How many kilometers will the family drive on the new route? Round the answer to the nearest tenth. Enter the answer in the box.
Using proportions, it is found that the family will drive 482.8 km on the new route.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:
D = 1.25 x 240 = 300 miles.
Since there are are approximately 48.28 kilometers in 30 miles, and 300/30 = 10, the distance in kilometers is given by:
D = 48.28 x 10 = 482.8 km.

A bird watcher on a cliff spotted a kingfisher 7 m above him.
Earlier he had seen it 11m below. What was the kingfisher’s
change in altitude?
Answer:
18 m
Step-by-step explanation:
11m + 7m is 18m
The final answer is 18m
The change in altitude of the kingfisher is 18 m.
What is the altitude length?The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex.
Suppose the distance above the cliff is represented by a positive integer.
Then the distance below it is represented by a negative integer.
Thus, change in altitude of the kingfisher
= 7-(-11)
= 7+11
= 18 m
Hence, the change in altitude of the kingfisher is 18 m.

Answer:
2sin((1)x + 135)-3
Step-by-step explanation:
Asin(Bx+C)+D
A = amplitude = distance from top to bottom divided by 2
y value of top = -1
y value of bottom = -5
distance from top to bottom = -1 - (-5) = 4
divide by 2 to get 4/2 = 2 as our amplitude
2π/B = period
in this case, we're working in degrees for our x axis - 2π = 360°
thus, 360°/B = period
period = time it takes to get from one high to the next (alternatively, one low to the next etc.) = 360 degrees in this case
thus, 360°/B = 360°
divide both sides by 360° and multiply both sides by B to isolate B
360/360 = B = 1
phase shift = -C/B
phase shift refers to how much the graph is shifted to the left/right. normally, the middle of a sin wave is at 0, with a peak being to the right of it. now, the middle of the sin wave (which has a peak to the right of it) is at x = -135 degrees to the right of a regular sine wave
thus,
-135 degrees = -C/B
B = 1
-135 degrees = -C
C = 135 degrees
D = vertical shift
the center is now at y = -3. normally, the center is at y = 0. thus, D = -3
our formula is thus
2sin((1)x + 135)-3

Step-by-step explanation:
Hey there!
The area of a shape is the total measurement of the inside of the shape
Meaning the parts I shaded in the screenshot
As you can see in the image, there is less area in shape B than shape A
Meaning, that the area has decreased
Now, Tom says that both area and perimeter has decreased
Lets check if the perimeter has decreased
If you look at it, the perimeter hasn't decreased at all
All that has happened was the shape getting a new form
The dimension are basically split
For example, if the top side of the square was 6 inches
Then the dimension after taking out a square from the shape would split
The top side of that square after is was split would be something along the ligns of 4 inches, and 2 inches and other dimensions like that
That is how I think of the perimeter and if it changes or not
But this explains why Tom is wrong
Since the perimeter is still the same
Tom is wrong
Cartographers, navigators, and surveyors are a few of the professionals that use instruments relying heavily on trigonometry.
Look up these professions and one other not listed and describe how trigonometry is used in each of them. Do you see how trigonometry is important in your everyday life? Why or why not?
Cartographers use trigonometry for topographic mapping, while navigators use it to direct navigation, helping to identify location and distance.
Surveyors, on the other hand, use trigonometry to measure spatial data, such as height and angles of the land and urban and rural georeferencing.
How important is trigonometry?Trigonometry studies the relationships between the sides and angles of a triangle. This calculation instrument is used for studies in various fields of scientific knowledge, such as the study of phenomena in mechanics, engineering and medicine.
