Answer:
Middle answer is right
Step-by-step explanation:
The first answer is obliviously wrong so therefore it is the last two options
-(x+1)^2
= -(x^2+2x+1)
= -x^2-2x-1-3 (add the -3)
= x^2-2x-4
y intercept make x=0 therefore y=-4
AOS is x= -b/2a
x=2/2 which is 1
therefore it isthe middle answer

Answer:
Circumference = 62.8
Step-by-step explanation:
The equation for discovering a circle's circumference is simple:
-------------------------------------------------------
C = 2πr
C is the circumference (how long is the circle around)
R is the radius (half of the width of the circle)
--------------------------------------------------------
So, instead of giving us the radius, they gave us the diameter. (the full width of the circle) So, we divide that by 2 to get the radius.
20/2=10
Now, time to fill in the equation.
C = 2π10
C = 20π
C = 62.8
*They told us to use 3.14 for pi.
someone please please help me with this ( a explanation on why you got this answer would be very helpful too) I would really appreciate it
Step-by-step explanation:
Let label this using a triangle.
We are sitting 300 ft away from the building.
We can look up to see the top of building at an angle of 60 degrees. So 60 degrees would be near where we standing at. The other angle of the top triangle would be 30 since that the height of building and the ground horizon is perpendicular to each other so they measure 90 degrees. Using triangle interior theorem, the missing angle would be 30.
We use another triangle since we are looking down.
The height of building and where we sitting at is perpendicular. The angle near we at would measure 15 and the missing angle would be 75.
The triangles both combine to form one triangle. They would form a isoceles triangle.
The most bottom angle of the triangles measure 75 while the angle where we are at of both triangle measure 75. so we have a isoceles triangle.
This means that the hypotenuse of the top triangle is equal to the length of the building.
To find the hypotenuse use 30-60-90 rules,
hypotenuse =twice of most shortest side.
[tex]h = 300 \times 2[/tex]
[tex]h = 600[/tex]
So the length of the building is 600.

A swim team ordered 36 jackets that each cost the same amount.
The total cost of the order was $1,116. Let c = the cost of each jacket.
How much did each jacket cost? Choose ALL of the division equations and
multiplication equations that represent this problem.
1,116c = 36
1,116, c, = 36
c = 1,116 • 36
c, = 1,116 • 36
36c = 1,116
36, c, = 1,116
1,116 ÷ 36 = c
Answer:
the cost of each jacket is 31$

In general, describe how the outcome of the hypothesis test changes as the level of significance decreases.
Answer:
The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.
Step-by-step explanation:
As the level of significance is decreased the area for the favorable outcomes is increased. The value of ∝= 0.1 has a narrower area of favorable outcomes then the values of ∝= 0.05 or 0.01 because the value 0.1 ( 1%) is closer to the middle value or at the extreme values of the distribution as the case may be for 2 tailed or 1 tailed test.
Significance level Two tailed Test One tailed test
0.1 ± 1.645 ±1.28
0.05 ±1.96 ± 1.645
0.01 ± 2.58 ± 2.33
So if the middle point is taken as zero we see that the spread of the area of the favorable values increases as the value of ∝ significance level decreases.
The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.
Julius bought F boxes of 24 plastic forks. He already had 39 plastic forks. Now, he has 135 plastic forks. How many boxes of plastic forks did Julius buy in all?
What is the best eqation?
A.
f - 24 × 39 = 135
B.
f + 24 × 39 = 135
C.
f × 24 - 39 = 135
D.
f × 24 + 39 = 135
Answer:
D
Step-by-step explanation:
boxes are the f. the amount in each is 24. theses will be mulitplied. then you want to add what he already had. that's the +39
Use the table to find the solution to the function f(x)=x^2(x-2) when x=2
The function f(x)=240x represents the cost of staying at a particular hotel for x nights at the full room rate of $240 per night. The hotel gives its rewards members a discount based on the length of their stay. Each additional night that rewards members stay earns them an additional 5% discount on the total cost of their stay up to a 30% discount. The function d(x)=0.05(x-1) for 1 < x ≤ 7 represents the percentage discount in decimal form for a rewards member staying x nights at the hotel.

A customer earns 1 free night per 10 nights stayed.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
Here, we have,
A hotel offers a reward program based on the number of nights stayed. The function f(x) represents the number of free nights earned as a function of x, the number of nights stayed.
f(x)=x/10
When we put x=10, we get f(1)=10/10=1
Here f(1) represents the number of free nights earned by the customer is 1 per 10 nights stayed.
When we put x=20, we get f(2)=20/10=2
Here f(2) represents the number of free nights earned by the customer is 2 per 20 nights stayed.
When we put x=30, we get f(3)=30/10=3
Here f(3) represents the number of free nights earned by the customer is 3 per 30 nights stayed.
When we put x=40, we get f(4)=40/10=4
Here f(4) represents the number of free nights earned by the customer is 4 per 40 nights stayed.
Then, the pattern permits you to conclude that a customer earns 1 free night for every 10 nights stayed.

Find the volume of the cylinder. Round your answer to the nearest hundredth.
9514 1404 393
Answer:
1763.01 m³
Step-by-step explanation:
The height of the cylinder will be ...
h = (18 m)sin(60°) = 9√3 m
The volume of the cylinder is ...
V = Bh
where B is the area of the end circle.
B = πr² = π(6 m)² = 36π m²
Then ...
V = (36π m²)(9√3 m) ≈ 1763.01 m³
The volume of the cylinder is about 1763.01 m³.
