y=-x^2+35x+100 Movie A
y=-5x+275 Movie B
When is the attendance for each movie the same?
After ___ days and after ___ days.
Answers
Answer:
After
days and after
days.
By solving a quadratic equation, we will see that the attendance will be the same after 5 days and after 35 days.
When is the attendance for each movie the same?
This will happen for the values of x such that:
y = -x^2 +35x + 100 = y = -5x+275
There says that the attendance for movie A is the same as the one for movie B. So we just need to solve that.
We can write the equation as:
-x^2 +35x + 100 = -5x+275
If we simplify this, we get:
-x^2 + 35x + 100 + 5x - 275 = 0
-x^2 + 40x - 175 = 0
This is a quadratic equation, the two solutions are given by Bhaskara's formula, we will get:
[tex]x = \frac{-40 \pm \sqrt{(40ft)^2 - 4*(-1)*-175)} }{2*-1} \\\\x = \frac{-40 \pm 30}{-2}[/tex]
So the two solutions are:
x = (-40 + 30)/-2 = 5
x = (-40 - 30)/-2 = 35
So, the attendance will be the same after 5 days and after 35 days.

2x = 4y + 8, x - 2y = 4
Answers
Answer: x = 8, y = 2, coordinates (8,2)
Step-by-step explanation:
2x = 4y + 8 (divide by 2 to get value of x)
x = 2y + 4
(now substitute x into the second equation to find value of y)
2y + 4 - 2y = 4
2y - 2y = 4 - 4 (divide by 2 to get value of y)
y - y = 2 - 2
y = 2
Now plug in value of "y" to get value of "x".
x - 2(2) = 4
x - 4 = 4
x = 8

Step 4 4 (3) minus 2 y = 4. 12 minus 2 y = 4. 2 y = negative 8. Y = negative 4. Step 5 Solution is (3, negative 4). Is Claire's solution to the system of equations correct? Explain why or why not.
Answers
Answer:
Claire should have gotten –2y = –8 instead of 2y = –8 in step 4.
Step-by-step explanation:
Following the steps taken :
4x - 2y = 4 - - - (1)
3x + 3y = 21 - - - (2)
Multiply (1) by 3 and (2) by 2
12x - 6y = 12 - - - (3)
6x + 6y = 42 - - - (4)
Add (3) and (4)
18x = 54
x = 54/18
x = 3
Put x = 3 in (1)
4(3) - 2y = 4
12 - 2y = 4
-2y = 4 - 12
-2y = - 8 (this is where the mistake lies)
It shouldn't be 2y = - 8 as stated

Tell us wether the line or segment is best described as a radius, chord, diameter, secant, or a tangent of 0O.
Answers
Answer:
AB - secant
DB - diameter
AB - chord
OB - radius
BC - tangent
(In the order they are in the picture)
Step-by-step explanation:
AB - The line goes through the circle and does not go through the center. This fits the definition of a secant, so line AB is a secant.
DB - Segment DB goes through the center and has endpoints on the circle. This fits the definition of a diameter, so DB is a diameter.
AB - Segment AB has endpoints on the circle and does not go through the center. This fits the definition of a chord, so segment AB is a chord.
OB - Segment OB is basically from the center to a point on the circle. This fits the definition of a radius, so segment OB is a radius.
BC - Line BC intersects the circle in only one point and does not go through it. This fits the definition of a tangent, so line BC is a tangent.

two features of world health organization
Answers
Answer:
I have five features so choose which one u like the best!
Step-by-step explanation:
1. Providing Leadership on Global Health
WHO is not the only major player in global health; there are several organizations who share the spotlight. But where this organization differs from others is that it continuously provides leadership in all areas of global health. This organization works with experts, volunteers, politicians, and governments to ensure that there is a set standard for global health and that it demonstrates this standard at all times. And because WHO is one of the most visible organizations, it is critical that they showcase leadership at all times, something it has done well since its inception.
2. Shaping the Research Agenda
Research is the main function of WHO; it is through research of disease and health policy that practices can be implemented on a global scale to save as many human lives as possible. Research is constantly changing and evolving, and WHO sees it as a priority to ensure that their own research practices are always beneficial to public health. The organization also distributes life-saving information all over the world, enabling the information they receive from research to make it to the communities that are affected the most by poor health conditions. 3. Setting the Standards for Global Health
One of the functions of WHO is to set international standards for the monitoring and implementation of global health policy and practices. While it continues to work hand-in-hand with governments and other non-governmental organization, it is this organization to which all other non-profit organizations look up to when discussing global health policy, norms, and practices. WHO does this by annually reviewing their own standards, taking constructive criticism from the global health community, and updating its standards as it sees fit.
4. Advocating for Evidence-Based and Ethical Policy
WHO is not the only organization that works to promote global health. It is, however, the one that takes the most responsibility for building a strong foundation on evidence-based science and ethical policies. Because the organization works all over the world, it is imperative that it takes the proper steps to ensure that their work is backed by sound science, ethical behaviors on their part, and demonstrates a high ethical standard for their international partners. This has been a function that WHO has been working tirelessly to improve as it is clear that the organization cannot act alone in the global health field; still, it remains a beacon of moral standards by upstanding global citizens.
5. Monitoring and Assessing Health Trends and Concerns
One of the main functions for the WHO continues to be tracking health trends across the globe. With malnutrition and preventable diseases supporting high mortality rates in underdeveloped countries, it is a mission of this organization to assess trends in order to ensure that its resources are going to the communities that need the most help. The Twelfth Programme of Work describes this in great detail and discusses not only child and maternal mortality rates, but also the spread of disease in every region, the expanding number of society that is aged 55 and over, and sanitation issues that contribute to the spread of disease.
WHO continues to be a symbol of integrity, rationality, and hope for the communities around the world that face global health crises. It is no wonder that it has an amazing reputation for providing excellent service for global communities while being an example for other organizations all over the world. Now that five important functions of the World Health Organization have been covered, consider learning more about current projects the organization is overseeing to see if help is needed. Hope this helps! :P

Answers

Joseph hits about 2 out of every 5 bats, and we want to find out the number of hits we had if he was up to bat 1,000 times.
[tex]\frac{2}{5} = \frac{x}{1000}[/tex]

2(1000) = 5(x)
2000 = 5x
Divide by 5 on both sides.
X = 400

Answers
Answer:
"24 pounds" is the appropriate answer.
Step-by-step explanation:
According to the question, the equation will be:
⇒ [tex]x+y=60[/tex]...(equation 1)
or,
⇒ [tex]\frac{55}{100}x+\frac{30}{100}y=\frac{40}{100}\times 60[/tex]
[tex]55x+30y=2400[/tex]...(equation 2)
Now,
By multiplying (equation 1) by 55 and (equation 2) by 1, we get
⇒ [tex]55x+55y=3300[/tex]...(equation 3)
⇒ [tex]55x+30y=2400[/tex]...(equation 4)
From equation 3 and 4, we get
⇒ [tex]25y=900[/tex]
[tex]y=\frac{900}{25}[/tex]
[tex]=36[/tex]
By putting the values of "y" in equation 1, we get
⇒ [tex]x=60-36[/tex]
[tex]=24[/tex]
Thus the value of x be "24 pounds".
If mAD = (17x + 2)°, mAC = (7x - 10°), and m∠ABC = (4x + 15)°, find m∠ABC
Please help
Answers
Answer:
m<ABC = 51degrees
Step-by-step explanation:
The angle at the vertex is half the difference of the angles at the intercepted arcs. Hence;
m<B = 1/2 (arcAD - arcAC)
<ABC = 1/2(17x + 2 -(7x - 10°))
4x + 15 = 1/2(17x-7x+2+10)
2(4x+15) = 10x+12
8x + 30 = 10x+12
8x-10x = 12-30
-2x = -18
x = 18/2
x = 9
Get m<ABC
m<ABC = 4x + 15
m<ABC = 4(9) + 15
m<ABC = 36 + 15
m<ABC = 51degrees
The measure of angle ∠ABC = 51 degree.
Since we know that,
For a circle,
The angle at the vertex is half the difference of the angles at the intercepted arcs.
Therefore,
m∠ABD = 1/2 (arcAD - arcAC)
⇒ ∠ABC = (1/2)(17x + 2 -(7x - 10°))
⇒ 4x + 15 = (1/2)(17x-7x+2+10)
⇒2(4x+15) = 10x+12
⇒ 8x + 30 = 10x+12
⇒ 8x-10x = 12-30
⇒ -2x = -18
⇒ x = 18/2
⇒ x = 9
Get m∠ABC
⇒ m∠ABC = 4x + 15
⇒ m∠ABC = 4(9) + 15
⇒ m∠ABC = 36 + 15
⇒ m∠ABC = 51 degree
