1.) Maria thinks (a + b)² = a² + b². Is she correct? Justify your reasoning. ​

Answers

Answer 1

Answer:

No, Maria is incorrect.

(a+b)^2 is actually equal to a^2 + 2ab + b^2.

Let me know if this helps!

Answer 2
We now have two formulas for (a+b)², which means we can set equation 1, from earlier, and equation 2 equal to one another.

Lastly, subtract 2ab from both sides, and look there’s the Pythagorean theorem!

The scatter plot shows the relationship between elevation and temperature on a certain mountain peak in North America. Which statements are correct?

A. The data shows one potential outlier

B. The data shows a linear association

C. The data shows a clustering pattern

D. The data shows a negative association

E. As elevation increases, temperature decreases

Answers

The scatter plot shows the data having a clustering pattern, and as elevation increases, temperature decreases.

What is a scatter plot ?

"Scatter plots are the graphs that present the relationship between two variables in a data-set. It represents data points on a two-dimensional plane or on a Cartesian system. The independent variable or attribute is plotted on the X-axis, while the dependent variable is plotted on the Y-axis. These plots are often called scatter graphs or scatter diagrams."

"A scatter plot is also called a scatter chart, scattergram, or scatter plot, XY graph. The scatter diagram graphs numerical data pairs, with one variable on each axis, show their relationship"

Since, the graph is a scatter plot so the data shows a clustering pattern.

and from the plot we can conclude that as elevation increases, temperature decreases.

Hence, C, E are the correct option.

Answers

Answer:

I think your answer is correct already. You just have to put your latus rectum, directrix, and focus into your drawing. :)

for asymptotes:

Let's change the centers into (-3, 2). Therefore, (y-2)² - (x+3)²/16 = 1

To get the asymptotes, let's equate the equation to zero (0) instead of one (1).

(y-2)² - (x+3)²/16 = 0

Notice that this equation is the difference of two squares.

Let x² = (y-2)² and y² = (x+3)²/16

Therefore, we have x² - y² =0

The factors of two squares are:

(x+y)(x-y)=0

Then, equating each factor to zero:

x+y=0

x-y=0

Substituting the real equations:

» (y-2) + (x+3)/4 = 0

y-2 = - (x+3)/4

y= -(x+3)/4 + 2

» (y-2) - (x+3)/4 = 0

y-2 = (x+3)/4

y= (x+3)/4 +2

Your teacher gave you 2/3 a bag of candy, but she only gave your friend 1/8 of a bag.
How much more of the bag did your teacher give you than your friend?

Answers

Answer:

Step-by-step explanation:

We can convert the 2/3 bag of candy that we got to 16/24, by multiplying both the top and bottom by 8. Similarly, we multipy the 1/8 bag of candy that our friend got by 3 on the top and bottom to get 3/24.

We find the difference between these two:

(16/24) - (3/24) = (16-3)/24 = 13/24

So we get 13/24 more of the bag of candy than our friend did. (That's more than half!)

(3x+23)+(7x-4)+(9x-6)+95=540

Answers

Answer:

Answer:

x = 22.7

Step-by-step explanation:

(3x + 23) + (7x - 4) + (9x - 6) + 95 = 540

combine all like terms

19x + 108 = 540

solve

subtract 108 from both sides

19x = 432

divide 19 from both sides

x = 22.7

Lewis is hiking in a state park when he spots a brightly colored bird in a distant tree. Lewis is 60 feet away from the tree, and the bird is perched on a branch 22 feet above the ground. Lewis is 5 feet tall.





What is the angle of elevation, in degrees, of Lewis' line of sight to the bird?

Answers

Answer:

he is 77 feet away from mr. birdie

Step-by-step explanation:

Quite certain it'd be 15.8 degrees.

Think about it, we're trying to figure out his angle of sight. If his eyes are 5 feet above ground, and the bird is 22 feet off the ground, there's really only a 17 ft height difference between the two. After doing the formulas and all, we can see that the angle of his vision is approximately 15.8.
