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!

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

The value of the given function is 6

Functions and values

Given the following expression 3*f(-4)-3*g(-2), to find the values, we can assume that;

f(-4) = 10g(-2) = 8

Substitute the given parameters into the expression to have:

3*f(-4)-3*g(-2)

= 3((10) - 3(8)

= 30 - 24

= 6

Hence the value of the given function is 6

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!)

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.

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.
