Morgan throws a ball up into the air. The height of the ball above the ground, in feet, is modeled by the function h(t) = −16t 2 + 24t, where t represents the time, in seconds, since the ball was thrown. What is the appropriate domain for this situation?
Answer:
I will give you the link below to a PDF that one of my young friends made for someone who had this exact question.
Step-by-step explanation:
The appropriate domain for this situation is [tex]\{t : 0 \leq t \leq 1.5\ \& \: t \in \mathbb R \}[/tex] (that means t can be any real number and between 0 and 1.5 (both endpoints included)
What is domain and range of a function?Domain is the set of values for which the given function is defined.
Range is the set of all values which the given function can output.
For this case, we have only those values of 't' as appropriate value, which are from t = 0 till the time when ball hits the ground, since after that the height will be constantly 0, but the height function will give negative values which doesn't model the situation correctly.
Thus, those values of t for which the equation [tex]h(t) = -16t^2 + 24t[/tex] correctly models the real world situation are said to be appropriate values of domain of this function.
The time when the ball will reach the ground will be when the height will be 0, thus,:
[tex]0 = -16t^2 + 24t\\2t^2 - 3t = 0\\(2t-3)(t) = 0\\t = 0, t = 3/2 = 1.5 \: \rm sec[/tex]
The height is 0 when ball starts going up(t=0), and when t = 1.5 the ball reaches ground.
Thus, the appropriate domain for modelling the situation is values of t in the interval [0, 1.5] (both endpoints are inclusive, as shown by big bracket).

A book is marked down by 28 percent from an original price of $19.50. What is the new price?
Step-by-step explanation:
First find 28% of $19.50:
($19.50) / (100) × (28) = $5.46
Now minus the 285 from the original price:
($19.50) - ($5.46) = $14.04
The answer is $14.04

plzz help me...tomorrow there is opt math test in my school...If I fail then i have to leave opt classes and go to eco....our teacher only taught trigonometry and I was absent 2 3 days due to sickness...plzz help me
Answer:
The steps are :
[tex] {tan}^{2} θ - {cot}^{2} θ = {sec}^{2} θ(1 - {cot}^{2} θ)[/tex]
[tex]RHS = {sec}^{2} θ(1 - {cot}^{2} θ)[/tex]
[tex]RHS = (1 + {tan}^{2} θ)(1 - \frac{1}{ {tan}^{2} θ} )[/tex]
[tex]RHS = (1 + {tan}^{2} θ)( \frac{ {tan}^{2}θ - 1}{ {tan}^{2} θ} )[/tex]
[tex]RHS = - \frac{(1 + {tan}^{2}θ)(1 - {tan}^{2} θ)}{ {tan}^{2} θ}[/tex]
[tex]RHS = - \frac{(1 - {tan}^{4} θ)}{ {tan}^{2} θ} [/tex]
[tex]RHS = \frac{ {tan}^{4} θ - 1}{ {tan}^{2}θ } [/tex]
[tex]RHS = {tan}^{2} θ - \frac{1}{ {tan}^{2}θ } [/tex]
[tex]RHS = {tan}^{2} θ - {cot}^{2} θ[/tex]
[tex]RHS = LHS (proven)[/tex]
What is 25% of 80? in table form
Answer:
20
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 80=100%.
Step 4: Similarly, x=25%.
Step 5: This results in a pair of simple equations:
80=100% (1).
x=25%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
{80} = {100%} {25%}
Step 7: Again, the reciprocal of both sides give
{80}= {25} {100}
x=20
Therefore, 25% of 80 is 20

In order to solve how many problems each person has solved, you have to multiply the fraction by the number of problems on their assignment. To do this, you multiply the numberator by the number of problems and then divide that by the denominator for both Dustin and Kelsey.
For Dustin, 3/8 * 24 = 72 / 8 = 9 problems completed
For Kelsey, 4/15 * 30 = 120/15 = 8 problems completed
Dustin has completed more problems
Answer:9
Step-by-step explanation:
Dustin done more he done 9 and kelsey done 8

The midpoint of \overline{\text{AB}}
AB
is M(-2, 5)M(−2,5). If the coordinates of AA are (1, 7)(1,7), what are the coordinates of BB?
The coordinates of the B is obtained as (-5, 3).
What is referred as coordinates?Coordinates are 2 numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane.
A coordinate plane does have four quadrants as well as two axes: x (horizontal) and y (vertical) (vertical). The point where the two axes intersect is known as the origin, and its coordinates are (0, 0).Coordinates are composed as (x, y), which means the x axis point comes first, accompanied by the y axis point.Now, as per the given question;
The coordinates of A is given as (1, 7).
The coordinates of mid point M is given as (-2, 5).
The coordinates are listed in pairs, with the x value at the top.
The shift in the x location is as follows:
1 - (-2) = 3
The change in y position is as follows:
7 - 5 = 2
Because the midpoint is half - way between B and A, the change will remain constant, so x is;
- 2 - 3 = -5
And for is;
5 - 2 = 3
Therefore, the values of the coordinates of B is found as (-5, 3).

The youth group at the church decided to plant geraniums and
daisies around the church grounds as a group project. Geraniums
in 6" pots cost $4 each and daisy plants cost $6 each. The youth
group spent $410 on 80 plants. How many geraniums and how many
daisy plants did the group buy?
Answer:
The youth group bought 35 geraniums and 45 daisy plants.
Step-by-step explanation:
We can solve this using a system of equations:
x + y = 80
4x + 6y = 410
X = Geraniums
Y = Daisies
First, let's solve for a variable in the first equation. I am going to solve for y in the first equation:
x + y = 80
y = -x + 80
Now that we have solved for y we can plug that back in to the 2nd equation:
4x + 6(-x + 80) = 410
4x - 6x + 480 = 410
-2x + 480 = 410
-2x = -70
x = 35
Now that we have found the amount of geraniums we can plug it back into the first equation and solve for y:
35 + y = 80
y = 45
Therefore the youth group bought 35 geraniums and 45 daisy plants.
Check:
(35) + (45) = 80
80 = 80
4(35) + 6(45) = 410
140 + 270 = 410
410 = 410
