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).

Step-by-step explanation:The perimeter is a measure of a polygon that describes the distance around the boundaries of a shape.
Perimeter Formula
The perimeter of a rectangle is equal to [tex]l + l + w + w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width. This can be simplified to [tex]2l+2w[/tex]. Now, we can plug in the expression we are given for width and length.
[tex]2(r-5s)+2(7r-2s)[/tex]Simplifying the Expression
The expression above does accurately depict the perimeter, but it should be simplified to make the expression easier to understand and use.
First, distribute the 2 inside the parentheses.
[tex]2r-10s+14r-4s[/tex]The next step is to combine like terms. Like terms are terms that have the same power and variable. For example, 2r and 14r are like terms.
16r - 14sThis is the simplified expression and the final answer.

Answer: The measure of angle 3 is 50 degrees.
Step-by-step explanation:
We know that angle 2 is 130 degrees.
Angle 1 and angle 2 are verticle angles which means that they are across and equal to each other.
So angle 1 and angle 2 are 130 degrees.
Add up both angle 1 and angle 2, 130 + 130 = 260.
Now, all of these angles add up to be 360 degrees in total as they make a circle and there are 360 degrees in one.
Subtract 260 from 360, 360 - 260 = 100.
Since both angle 3 and angle 4 are also verticle angles we need to split the 100 degrees evenly, 100 ÷ 2 = 50.
So, angle 3 is 50 degrees.

Answer:
0.1125
Step-by-step explanation:
1.35 divided by 12 = 0.1125
Answer:
$0.11 per egg
Step-by-step explanation:
unit cost means how much each one costs
there are 12 eggs in a dozen
so all you have to do is divide $1.35 by 12
which equals $0.1125
but money is only counted by the hundredths place so we have to round
and that would be $0.11

Ms. Barcht Open a savings account with $50 and deposit $25 every week. Mrs. Greene save $75 every week. How many weeks will Mrs. Greene have more money in her account than ms. Bracht?
A. 25x+75>50
B. 75x=25x+50
C. 75x>25x+50
D. 75x<25x+50
Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
Answer:
The answer would be C. 75x>25x+50
Step-by-step explanation:
The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150

Janice puts a fence around her rectangular garden. The garden has a length that is 9 feet less than 3 times the width. Which system of equations represents is the dimensions of the rectangular garden if the perimeter is 63?
Step-by-step explanation:
Let the width of the garden be b and its length is 9 feet less than 3 times the width.
Length = 3b-9 ...(1)
The perimeter of the garden = 63
We need to find the system of equations that represents is the dimensions of the rectangular garden.
Perimeter = 2(l+b)
63 = 2(3b-9+b) [from equation (1)]
31.5 = (3b-9+b)
31.5 = (4b-9)
31.5+9 = 4b.....(2)
b = 10.12
Hence, the equations are showsn in equation (1) and (2).

Answer:
17.3%
Step-by-step explanation:
The rate of return is the net profit divided by the purchase price.
The purchase price was ...
(20 share) × ($30/share) = $600
The net proceeds from the sale were ...
proceeds = selling price - commission
= $710 -$6 = $704
So, the net profit is ...
profit = $704 -600 = $104
And the rate of return is ...
profit / investment = $104/$600 = 17.3%

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (1, 5).
Answer:
4x-y+1=0
Step-by-step explanation:
here,given equation of a line id
4x-y-2=0.. eqn(i)
equation of any line parallel to line (i) is
4x-y+k=0...eqn(ii)
since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]
4*1-5+k=0
or, 4-5+k=0
or,-1+k=0
•°•k=1
substituting the value of k=1 in eqn(ii),
4x-y+1=0 is the required equation of the line.

Sasha has $850 to deposit into two accounts.
Sasha will deposit $450 at First Oak Bank.
She will deposit the rest at River Point Bank.

Amount in First Oak Bank is $87.84 than at River Point after 2 years.
What is Simple Interest and Compound Interest?Simple interest is the interest obtained over the principal amount on a certain rate.
Compound interest is the amount of interest which is calculated on the principal amount as well as the amount accumulated over the previous period.
First oak bank is simple with 6% interest.
Final amount in simple interest, A = P(1 + rt), where P is the principal amount , r is the interest rate and t is the number of years.
A = 450 (1 + (0.06 × 2)) = $504
River point bank is 2% compounded annually
Final amount in compound interest, A = P(1 + r/n)^(nt), where, P is the principal amount, r is the interest rate, t is the number of years and n is the number of times interest compounded annually.
P = 850 - 450 = 400
n = 1, since compounding is only 1 time in a year
A = 400(1 + 0.02)² = $416.16
Amount which is more in First oak is $504 - $416.16 = $87.84
Hence the amount more in the First oak account is $87.84.

James needs to buy shirts for his business. Company C charges customers a one-time $50 printing fee plus $10 for every shirt. Company D charges a one-time $20 printing fee plus $15 for every shirt. Which inequality can be used to find s, the minimum number of shirts that can be purchased so that the total charge at Company C is less than the total charge at Company D? 50s+10>20s+15 50s+10 20+15s
Answer:
50 + 10s > 20 + 15s
Step-by-step explanation:
This is the answer because if James pays for 1 shirt from company C he would be paying $60, but if he were to pay for 1 shirt at company D he would be paying $35. So that's why its >. Anyway, the s goes on the second number because that's the price for every shirt, And the first number is by itself because its a one-time printing fee.
