An object is launched directly in the air at a speed of 48 feet per second from a platform located 12 feet above the ground. The position of the object can be modeled using the function f(t)=−16t2+48t+12, where t is the time in seconds and f(t) is the height, in feet, of the object. What is the maximum height, in feet, that the object will reach?
9514 1404 393
Answer:
48 ft
Step-by-step explanation:
For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.
t = -48/(2(-16)) = 1.5
Then the maximum height is ...
f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12
f(1.5) = 48
The maximum height the object will reach is 48 feet.

Answer:
i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2
Answer:
Step-by-step explanation:
c = 0.5t + 2
12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒ t = 20
c = 0.5(30) + 2 ⇒ c = 17
20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ t = 36

Step-by-step explanation:
Directions: If I || m, classify the marked angle pair and give their relationship, then solve for x.
Answer/Step-by-step explanation:
1. If l is parallel to m, therefore:
58° and (5x - 2)° are Corresponding Angles.
Relationship: 58° = (5x - 2)°
Solve for x
58 = 5x - 2
Add 2 to both sides
58 + 2 = 5x - 2 + 2
60 = 5x
Divide both sides by 5
60/5 = 5x/5
12 = x
x = 12
2. If l is parallel to m, therefore:
134° and (16x + 22)° are Alternate Exterior Angles.
Relationship: 134° = (16x + 22)°
Solve for x
134° = 16x + 22°
Subtract 22 from both sides
134 - 22 = 16x + 22 - 22
112 = 16x
Divide both sides by 16
112/16 = 16x/16
7 = x
x = 7
3. (7x - 1)° and 125° are Alternate Interior Angles.
Relationship: (7x - 1)° = 125°
Solve for x
7x - 1 = 125
Add 1 to both side
7x = 125 + 1
7x = 126
Divide both sides by 7
x = 18
4. (9x + 2)° and 133° are Same Side Interior Angles.
Relationship: (9x + 2)° + 133° = 180° (supplementary)
Solve for x
9x + 2 + 133 = 180
9x + 135 = 180
9x = 180 - 135
9x = 45
x = 5
5. (8x - 77)° and (3x + 38)° are Alternate Exterior Angles
Relationship: (8x - 77)° = (3x + 38)°
Solve for x
8x - 77 = 3x + 38
8x - 3x = 77 + 38
5x = 115
x = 23
6. (11x - 47)° and (6x - 2)° are Corresponding Angles.
Relationship: (11x - 47)° = (6x - 2)°
Solve for x
11x - 47 = 6x - 2
11x - 6x = 47 - 2
5x = 45
x = 9
7. (13x - 21)° and (5x + 75)° are Alternate Interior Angles.
Relationship: (13x - 21)° = (5x + 75)°
Solve for x
13x - 21 = 5x + 75
13x - 5x = 21 + 75
8x = 96
Divide both sides by 8
8x/8 = 96/8
x = 12
8. (9x - 33)° and (5x + 3)° are Consecutive Exterior Angles
Relationship: (9x - 33)° + (5x + 3)° = 180°
Solve for x
9x - 33 + 5x + 3 = 180
14x - 30 = 180
14x = 180 + 30
14x = 210
x = 15
the amount of rent paid by a teacher is two-fifths of the teacher's monthly income. The rent paid by the teacher is $1100. What is the teacher's monthly income?
Answer:
ඞ
Step-by-step explanation:
The teacher's monthly income is $2750.
What is a fraction?"A number that expresses parts of a whole object or a set of objects is called as a fraction. Parts of a fraction are a numerator, a denominator and a fraction bar."
According to the question
Rent paid by the teacher = $1100.
Amount of rent paid by a teacher is two-fifths of the teacher's monthly income.
Dividing rent paid by the teacher to two-fifths(fraction) of the teacher's monthly income gives us teacher's monthly income.
= [tex]\frac{1100}{\frac{2}{5} }[/tex]
= [tex]\frac{1100}{2}[/tex] × [tex]5[/tex]
= 550 × 5
= $2750
Hence, the teacher's monthly income is $2750.

How does a straight line represents the proportionality ratio?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written to express proportional relationship as -
y = kx {k is constant}
We have Jean is [x] years old and Jonathan is [y] years old
Assume that Jonathon is [m] years older than Jean. Then we can write -
y = mx
or
m = y/x
Therefore, Jonathon is [y/x] years older than Jean.

Paul is selling his paintings at the town Square. He has 35 paintings to sell in all and needs to sell at least 17 paintings in one day to
recover his cost. He has already sold 3 paintings since the morning and has 5 more hours to sell his paintings, Paul wants to know
about how many paintings he should sell per hour to recover his cost.

e
17 3 5x - 3235
17 5 5x + 3235
17 5 5x - 3535
Answer:Paul should sell 3 paintings per hour to recover his cost.
Step-by-step explanation:
Total paintings = 32
Minimum amount to sale = 17
Paintings sold = 3
Paintings left = 17 - 3 = 14
Time left = 5 hours
Therefore, he needs to sell 14 paintings in 5 hours.
5 hours = 14 paintings
1 hour =
Rounding off to nearest whole number;
2.8 paintings = 3 paintings
Answer:
17 ≤ 5x + 3 ≤ 35
Step-by-step explanation:
Let x be the average number of painting he needs to sell every hour.
He has 5 hours to sell his paintings. So, the number of paintings he sells during the 5 hours is 5x.
He has already sold 3 paintings since the morning.
Write an expression to represent the total number of paintings sold for the day.
Write an inequality for the minimum number of paintings that he has to sell.
Write an inequality for the maximum number of paintings that he has.
Now, combine the two inequalities
So, an inequality that represents the given situation is 17 ≤ 5x + 3 ≤ 35.

Complete question is;
A family of 6 is visiting a mall. The mall has 10 exit doors. Assume random selection. Find the probability that
a. No family member chooses the same exit door.
b. Every family member chooses the same exit door.
Answer:
A) 0.6
B) 0.1
Step-by-step explanation:
A) We are told there are 10 exit doors and the family consists of 6 people.
This implies that for them not to choose the same exit door there will be 6 different doors they will pass.
Thus;
Probability that the no family member chooses the same exit door = 6/10 = 0.6
B) If they all choose the same exit door, it means only 1 out of the 10 exit doors will be used by them.
Thus;
Probability that every family member chooses the same exit door = 1/10 = 0.1
