Answer:

Step-by-step explanation:

y = -x² + 4x + 1

factor out the leading coefficient

y = -(x² - 4x) + 1

complete the square

y = -(x² - 4x + 2²) + 2² + 1

y = -(x-2)² + 5

Answer:

[tex]6\frac{1}{3}[/tex] = [tex]2\frac{1}{2}[/tex] * 2 + [tex]\frac{x}{2}[/tex]

Step-by-step explanation:

lets start with what we know.

the recipe calls for 2 [tex]\frac{1}{2}[/tex] cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2

2 [tex]\frac{1}{2}[/tex] * 2 = 5 cups of yogurt.

the total of yogurt and oats is [tex]6\frac{1}{3}[/tex] and we know how much yogurt we have so we subtract that from the total of both.

[tex]6\frac{1}{3}[/tex] - 5 = [tex]1\frac{1}{3}[/tex]

the oats after doubling were [tex]1\frac{1}{3}[/tex] cups so u divide it by 2

[tex]1\frac{1}{3}[/tex] / 2 = [tex]\frac{2}{3}[/tex] before doubling

Step-by-step explanation:

Exterior angles is the sum of the two opposite angles

so 100 - 72° = x

x = 28°

thats how you get 28°

720° is the sum of angles in a regular hexagon

720 / 6 = 120°

So the interior is 120°

To find the exterior angle, simply subtract the interior degree from 180.

external degree = 180 - 120 = 60

The exterior angle of a regular hexagon is 60 degrees.

Step-by-step explanation:

Alright, so over here, the triangle is called an exterior angle. When there is a line outside the triangle.

And the line outside the triangle means that the line outside is equal to the 2 other angles.

So in this case, it would be 100 = 72 + x.

Now let's do 100 - 72 to get the missing x.

100 - 72 is 28, right?

So our answer is 28.

Now the next one.

Regular hexagons interior angle sum using the formula (n-2) × 180 = (6-2)×180 = 4 × 180° = 720°

every interior angle then would be 720/6 = 120°

Now exterior angles are always 360°

so all angles = 360/6 = 60º.

Answer:

3x+yl=11

-2x+y=11

y=11-3x

-2x+11-3x=11

-5x=11-11

so x=0

y=11-0

y=11

Answer:

15 total miles each hour

Step-by-step explanation:

for this situation and the information given in the question, all we have to do is divide the total amount by 3 (since its 1/3) to get the amount of total miles they drove at, wich is the speed they drove in this case

(sidenote: kinda slow if ya ask me but ok XD)

hope this helps you :D

Answer:

-1

Step-by-step explanation:

Any number less than -2 (ex -3, -4, -5) are less than -2

Answer:

-1

Step-by-step explanation:

If you look at a number line, you will see that -1 comes before -2. Since -2 is a negative number, then the lower the number, the greater it is.

Answer:

i think 2.7

Step-by-step explanation:

Answer:

For the first group we have the pairs:

year           population

0                20

1                 80

2                320

3                 1,280

4                 5,120

5                 20,480

Here we can see that the population quadruples each year

(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)

then the population equation is:

P(0) = 20

P(1) = 20*4

P(2) = (20*4)*4 = 20*4^2

We already can see the pattern, then we can write this relationship as:

P(t) = A*(4)^(t)

Where:

t represents time in years, and A is the initial population, that we know it is 20, then:

P(t) = 20*(4)^t

This is the function that represents the table.

B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:

Q(t) = 20*(3)^t

C) Now, if the initial population of the second group is 40, the equation becomes:

Q(t) = 40*(3)^t

The population by year 3 is given by replacing t by 3, then:

Q(3) = 40*(3)^3 = 1080

And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:

1,280 - 1,080 = 200

So the first group is larger by 200 squirrels.

Answer:

I don't remember how but you need to work out the frequency, because what you're using is the cumulative frequency.

Answer:

c. (4,3)

Step-by-step explanation:

If you look at all the rest of the coordinates, compared to (4,3). None of them are in the red area. They are either in the blue, or the orange. To be a solution it has to be in both areas, (the red). Hope this helps!

Answer:

D. 211

Step-by-step explanation:

180-19=161

161+50=211

19+(211(x)-50)=180

211° is the value of x since if u substitute it u will get your answer note that angle on a straight line is 180°
