A child lets go of a balloon that rises at a constant rate. 5 seconds after it was released, the balloon is at a height of 16 feet above the ground. After 20 seconds of rising, it is at a height of 52 feet above the ground. 1. Write a linear model for the height, h, of the balloon as a function of the number of seconds, s that it has been raising. 2. What was the height of the balloon initially before the child let it go? 3. Use your model to predict the height of the balloon after 90 seconds. Only an algebraic solution will receive credit.
Answer:
1. h = 2.4t + 4
2. 4 feet
3. 220 feet
Step-by-step explanation:
1. Write a linear model for the height, h, of the balloon as a function of the number of seconds, s that it has been raising.
Since the balloon rises at a constant rate, we find this rate by using the initial and final values of height and time at 5 seconds and 20 seconds respectively which are 12 feet and 52 feet respectively.
So, rate = gradient of line
= change in height/change in time
= (52 ft - 16 ft)/(20 s - 5 s)
= 36 ft/15 s
= 2.4 ft/s
Now the equation of the line which shows the height is gotten from
(h - h')/(t - t') = rate
Using h'= 16 feet and t' = 5 s, we have
(h - 16)/(t - 5) = 2.4
h - 16 = 2.4(t - 5)
h - 16 = 2.4t - 12
h = 2.4t - 12 + 16
h = 2.4t + 4
where h is the height of the balloon above the ground and t is the time spent in the air in seconds.
2. What was the height of the balloon initially before the child let it go?
We obtain the initial height of the balloon before the child let go at time, t = 0 the time before the child let go.
So, substituting t = 0 into the equation for h, we have
h = 2.4t + 4
h = 2.4(0) + 4
h = 0 + 4
h = 4 feet
So, the height of the balloon before the child let go is 4 feet above the ground.
3. Use your model to predict the height of the balloon after 90 seconds.
We insert t = 90 s into the equation for h. So,
h = 2.4t + 4
h = 2.4(90) + 4
h = 216 + 4
h = 220 feet
So, the height of the balloon after 90 s is 220 feet above the ground.

The ________________________________ is the intersection of the three angle bisectors in a triangle.
Group of answer choices
Circumcenter
Incenter
Centroid
Orthocenter
Answer:
Circumcenter
Step-by-step explanation:
The three perpendicular bisectors of the sides of a triangle meet in a single point, called the circumcenter . A point where three or more lines intersect is called a point of concurrency. So, the circumcenter is the point of concurrency of perpendicular bisectors of a triangle.

Answer:
Its A. g = 11
Step-by-step explanation:
Follow PEMDAS (Parantheses, exponents, multiplication, division, addition, and subtraction)
(g = 11 - 9 = 2)
7(2) = 14
14 + 12 = 26
I hope this helps u! :D
9514 1404 393
Answer:
(A) g = 11
Step-by-step explanation:
We can find out by undoing what is done to g.
26 = 7(g -9) +12
14 = 7(g -9) . . . . . . . . subtract 12
2 = g -9 . . . . . . . . . divide by 7
11 = g . . . . . . . . . . add 9
The value of g that makes the equation true is g = 11.

On what interval is the function positive?
Answer: (-∞,2)
Step-by-step explanation: 2 is not included in the interval since at x=2, the function crosses the x axis, meaning it is not positive, and instead 0.
All x values below 2 are positive.
Omar is going to an amusement park for his birthday party. It costs $30 for the first person's ticket, plus $5 for each additional ticket. If the budget for his party is $125 how many friends could he invite?
Answer:
he could invite 19 friends

Bernice monthly paycheck can be represented by p(d) = 21od + 1100. She also earns money babysitting which can be represented by b(d) = 36d + 100. In both functions, d represents the number of weekdays. Write a function, t(d) , that represents Bernice's total monthly income.
Answer:
t(d) = 246d + 1200
Step-by-step explanation:
t(d) = p(d) + b(d)
Where,
t(d) = Bernice's total monthly income
p(d) = monthly paycheck
b(d) = babysitting earnings
d = number of weekdays
p(d) = 210d + 1100
b(d) = 36d + 100
t(d) = p(d) + b(d)
= (210d + 1100) + (36d + 100)
= 210d + 1100 + 36d + 100
= 246d + 1200
t(d) = 246d + 1200

The value of y varies directly with x. If x = 5 when y = 12, what is the value of x when y = 30?
Answer:
12.5
Step-by-step explanation:
y= kx
k= y/x
x= 5, y= 12
k = 12/5
Therefore the value of x when y is 30 can be calculated as follows
y = kx
30= 12/5x
x= 30÷12/5
x= 30× 5/12
x= 150/12
x= 12.5

Step 1: Define
2x - 12 = -52
Step 2: Solve for x
Add 12 on both sides: 2x = -40Divide 2 on both sides: x = -20Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 2(-20) - 12 = -52Multiply: -40 - 12 = -52Subtract: -52 = -52Here we see that -52 does indeed equal -52.
∴ x = -20 is the solution to the equation.

Determine if the relation is a function if so state the domain and range
Answer:
Function - Yes
Domain - [-3,0,3,4]
Range - [1,2,2,5]
Step-by-step explanation:
In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.
