Based on what you know about the information provided in the
graph and the roots or solutions of an equation,which function,
in factored form, does the graph below represent?*
O y = (x - 12)(x + 4)
O y = (x - 3)(x +4)
O y = (x - 12)(x-4)
O y = (x + 3)(x-4)
The function that forms the polynomial is (x + 3)(x - 4) = y

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
Polynomials are classified based on degree as linear, quadratic, cubic.
Quadratic polynomial is of degree two and has two roots.
From the graph:
x = -3 and x = 4
(x + 3)(x - 4) = y
The function that forms the polynomial is (x + 3)(x - 4) = y

Step-by-step explanation:
P = binomial probability
x = number of times for a specific outcome within n trials
[tex]{n \choose x}[/tex] = number of combinations
p = probability of success on a single trial
q = probability of failure on a single trial

The number is technically infinite, but since it's the largest multiple of 5, we can't make it infinite. So in this case, use the line method to represent the instance that it will go on, and on, and on.
The last number will end in 6, because any multidigit number with all 0's after the number, minus 4, is that number followed by 6 in the ones place.
2. An object is launched at an upward velocity of 96 feet per second from the top
of a building 160 feet above the ground. Use the vertical motion model
h=-16t+vt+c where h is the ending height of the object, c is the initial height, in
feet, of the object, t is the time in seconds, and v is the velocity of the object
Answer:
3,304
Step-by-step explanation:
The ending height of the object is 304 feet.
Given that, an object is launched at an upward velocity of 96 feet per second from the top of a building 160 feet above the ground.
The vertical motion model is [tex]h=-16t^2+vt+c[/tex].
Here, c=160 and v=96
Now, [tex]h=-16t^2+96t+160[/tex]
Maximum h is at axis of symmetry.
Thus, [tex]t=-\frac{b}{2a}[/tex]
[tex]= -\frac{96}{2\times(-16)}[/tex]
[tex]= -\frac{96}{(-32)}[/tex]
[tex]= 3[/tex]
Substitute [tex]t=3[/tex] in [tex]h=-16t^2+96t+160[/tex], we get
[tex]h=-16\times3^2+96\times3+160[/tex]
[tex]= -16\times9+288+160[/tex]
[tex]= -144+448[/tex]
[tex]= 304[/tex]
Therefore, the ending height of the object is 304 feet.

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.
Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.
Answer:
In the theory of chances, it states that no matter what the average, chance can change it no matter what. Like someone getting good chances in a video game 2 times in a row. its rare, but compared to how many people play the game and how often, it was bound to happen at some point. the chances could be tiny, but it could still happen. just like if 100 monkeys were on typewriters typing 60 wpm, one would eventually type Abraham Lincoln. low chance, but if all these monkeys are doing it enough, it would happen eventually. so, it is entirely possible that 2/3 of his next predictions will be correct.

Answer:
96 + 150 + 2x + x = 360⁰
240 + 3x = 360⁰
3x = 120
x = 40⁰ hope it's help you
Answer: 58
Step-by-step explanation:
Since the shape has 5 sides, the sum of the internal angles is (5-2)*180 = 3*180 = 540 degrees.
Therefore, 96+150+120+2x+x = 540
386 + 4x = 540
3x = 174

b) $0.15c + $125 = $305
c = number of cookies baked
Adrienne baked 1200 cookies in one day
Step-by-step explanation:
Expenditure:
ingredients = $125labor/baking = $0.15 per cookieTotal = $305Part A
b) $0.15c + $125 = $305
Part B
c = number of cookies baked
Part C
0.15c + 125 = 305
⇒ 0.15c = 305 - 125
⇒ 0.15c = 180
⇒ c = 180 ÷ 0.15
⇒ c = 1200
Adrienne baked 1200 cookies in one day
The area of a trapezoid is 500 square inches. The bases of the trapezoid are 16 inches and 24
inches. What is the height of the trapezoid, in inches?
Step-by-step explanation:
area = ½ (a+b) x h
500in² = ½ (16+24) x h
500in² = ½ (40) x h
500in² = 20 x h
500in²
20 = h
h = 25 inches :)
An isosceles triangle has an angle that measures 94º. Which other angles could be in that
isosceles triangle? Choose all that apply.
43°
8°
81°
59°
Answer:
43°
Step-by-step explanation:
In a isosceles triangle, two angles HAVE to be equal.
This means that 94 can be one of the angles that are equal, or the angle that is not equal to another angle.
Let's start with the fact that 94 can be one of the angles that are equal. (Note: angles in a triangle add up to 180)
94+94+x=180
188+x=180
There is NOT a possible value for x in this situation, as you cannot have a negative value of an angle. Therefore we must try the other situation where 94 is the angle that is not equal to another angle.
x+x+94=180
2x+94=180
Subtract 94 from both sides
2x=86
Divide both sides by 2
x=43
Therefore the answer is 43°

Dilation factor=1/4
Total increase in coordinates=1/4=0.25=0.25Now multiply each coordinates with 1.25
D=(4,8)
D'=4(0.25),8(0.25)=(1,2)E=(12,16)
E'=12(0.25),16(0.25)=(3,4)F(-4,-12)
