Every autumn, the North American Monarch
butterfly migrates up to 3,000 miles to California and Mexico where it hibernates
until early spring. The butterfly travels on average 50 miles per day.

Answers

Part A

The equation is d = 50t

This is because the slope of 50 represents how many miles per day the butterflies cover (on average). The y intercept is 0 to indicate that 0 miles have been traveled initially.

You can think of this as the equation y = 50x

If t = 1, then d = 50t = 50*1 = 50 miles have been covered

If t = 2, then d = 50t = 50*2 = 100 miles have been covered

And so on.

==========================================================

Part B

You'll have these values in the bottom row (in the order presented): 50, 100, 150, 200, 250

You can plug in the values t = 1, t = 2, t = 3, t = 4 and t = 5 into d = 50t to find those answers in bold.

Or you could add on 50 each time to generate each new value. We start at 50 since t = 1 corresponds to d = 50.

==========================================================

Part C

You can keep the pattern of 50,100,150, ... going until you reach 2500. Then note the t value that pairs with d = 2500

In my opinion, that's the slower method.

The quicker method is to plug d = 2500 into the equation for part A, and then solve for t.

d = 50t

2500 = 50t

50t = 2500

50t/50 = 2500/50 ....... divide both sides by 50

t = 50

It will take 50 days for the average distance traveled to be 2500 miles.

Convert the function f(x) = x^2 + 2x-8 to standard form. Then state the vertex and domain and range of the function.

Answers

Answer:

f(x) = (x + 1)² - 9

vertex: (-1, -9)

domain: all real numbers

range: y ≥ -9

Step-by-step explanation:

y = x² + 2x - 8

convert by 'completing the square' method

x² + 2x + 1 = 8 + 1

(x + 1)² = 9

f(x) = (x + 1)² - 9

Find angle E and F please

Answers

Answer:D 120 degrees, F 60 degrees

Step-by-step explanation:

it is a parallelogram which means the 2 angles add up to 180 degrees. 5x+2x+12=180. Then solve, 7x=168, x=24. Then Substitute back into the angles. E is 5*24 which is 120. F is same as D which is 2x+12=60. Hope this helped

Answer:

Angle F = 60

Angle E = 120

Step-by-step explanation:

Angle E = Angle G whereas Angle D = Angle F

Angle D + Angle G = 180, Angle E + Angle F = 180

Angle D + Angle E + Angle F + Angle G = 360

In this case, it's Angle E and F. Keep in mind that Angle D is the same as Angle F so you can just do 5x + 2x+12 = 180.

Subtract 12 on both sides to get 168, so the equation is 5x + 2x = 168.

Add 5x and 2x to get 7x. Your final equation is 7x = 168

Divide 7 on both sides to get 24.

So x = 24

Now plug in x in for both angle equations so Angle F = 2(24) + 12 and you get 60.

For Angle E you plug in 5(24) and you get 120.

4. Reflection over the x-axis

Answers

Answer:

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Choice 1.

Step-by-step explanation:

Reflection over the x-axis

Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).

The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

PROMT: Should the developed world care about and aid in the accessibility of education (science) and technology worldwide? My essay- Did you know that 32 million children in the Sub-Saharan area of Africa are uneducated. What should developed countries do to help this problem? I believe that to solve uneducation, developed countries should put forward more money and time into helping these countries with access to technology and education. One way that developed countries can aid developing countries is by giving access to technology. Access to technology will affect developed countries positively. One it will affect developing countries is that students will be able to access information better and have a higher chance of succeeding in school. Teachers in developing countries will also be affected because they can use it track the work of children better and will be to present information in an efficient manner. It can also affect the country by boosting is economy and help create new business. Even if technology can help developing countries, it won't be easy. First of all, most developing countries do not have power, and a lot of people don't bother going to school. These two things will make it harder because if there is no power how will the technology be used and if people don't really study then it won't aid that country at all. Despite the problems that technology will cause, there are solutions. The developed countries can give money towards constructing power lines in developing countries. Technology will encourage the people of developing countries to try to get and education, and this will cause more people to be educated. But even if that does happen, there will still be some problems in the way. In developing countries, some teachers don't know how to use technology in the correct way. Also some countries rarely have any schools, meaning that the developed countries will need to construct schools. Despite the amount of problems that will be caused due to developed countries aiding developing countries, it doesn't mean it's impossible. This will push Developing countries into trying to complete the goal of aiding developing countries in the aid of technology and education. pls look at the image and answer quickly!
