The height of the baseball after the 1.5 seconds of time as the boy throw the ball is 15.5 meters.
How to model a mathematical function?The mathematical functions is used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple mathematical function-
Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.A boy throws a baseball across a field. The ball reaches its maximum height, 18 meters, after 1 second.
After approximately 2.3 seconds, the ball lands on the ground.
The ball’s motion can be modeled using the function
[tex]f(x) = -10x^2 +20x+ 8[/tex]
Here, x represents the time in seconds.
As, the height of the ball 1.5 seconds after it is thrown has to be found out. Thus, put the values of in the above equation as,
[tex]f(x) = -10(1.5)^2 +20(1.5)+ 8\\f(x)=-22.5+30+8\\f(x)=15.5\rm \; m[/tex]
Hence, the height of the baseball after the 1.5 seconds of time as the boy throw the ball is 15.5 meters.

Henry is playing a game using a bag of tokens that contains exactly 28 black tokens and 12 white tokens. On each player’s turn a single token is drawn at random from the bag and then returned to the bag at the end of the turn. Each token is the same size and shape. Henry recorded the first 10 draws as either black (B) or white (W) as shown below.
B, W, W, W, B, B, B, W, B, B
Part B: Based on the information given, what is the experimental probability of the next player drawing a white token? Explain
Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the next player drawing a white token.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, these number of outcomes are taken from previous trials.
In this problem, in the first 10 draws, 4 resulted in the player drawing a white token, hence:
p = 4/10 = 0.4.
There is a 0.4 = 40% experimental probability of the next player drawing a white token.

Quadratic formula: [tex]\frac{-b +-\sqrt{b^{2} - 4ac } }{2a}[/tex]
Step-by-step explanation:
We have -0.08t² + 1.6t + 2 = 9
Subtract 9 from both sides
-0.08t² + 1.6t + 2 = 9
- 9 - 9
-0.08t² + 1.6t - 7 = 0
We will have to use the quadratic formula
a = -0.08
b = 1.6
c = -7
[tex]\frac{-1.6 +-\sqrt{1.6^{2} - 4(-0.08)(-7) } }{2(-0.08)}[/tex]

What is a convergent series? what is a divergent series?.
Answer:
Step-by-step explanation:
A convergent series is a series whose partial sums tend to a specific number or a limit.
Example: [tex]3+1+\frac{1}{3}+\frac{1}{9}+.~.~.[/tex]
This is because a series is convergent if
[tex]-1 < r < 1[/tex]
where r is the common ratio
and for the question above
[tex]r=\frac{1}{3}[/tex]
A divergent series is a series whose partial sums do not approach a limit. Divergent series typically go to positive infinity, negative infinity, or don't approach a specific number.
Example: [tex]4+12+36+108~.~.~...[/tex]
This is a divergent series because the common ratio is;

a store buys 120 baseball hats at 0.50 each including tax.the store sells the hats at Markup of 50% they sell all of the hats during the season for the selling price.How much money do they receive for the sales of all the hats
Answer:
R90
Step-by-step explanation:
120 hats sold and each = $0.50
0.50 × 120 = R60 (all the baseball hats cost)
50% of 0.50 = 0.25
0.25 × 120 = 30 (markup price)
60 + 30 = 90 ( total received for the sales)

An algebra tile configuration. Only the Product spot is shown. 8 tiles are in the Product spot in 3 columns with 3 rows. First row: 1 x squared, 2 x. Second row: 1 x, 2. Third row: 1 x, 1. How many more unit tiles need to be added to the expression x2 4x 3 in order to form a perfect square trinomial? 1 2 3 4.
The number of unit tiles needed to be added to the expression [tex]x^2 + 4x + 3[/tex] for making it perfect square trinomial is: Option A: 1
What is a perfect square polynomial?If a polynomial p(x) can be written as:
[tex]p(x) = [f(x)]^2[/tex]
where f(x) is also a polynomial, then p(x) is called as perfect square polynomial.
What are terms in polynomials?Terms are added or subtracted to make a polynomial. They're composed of variables and constants all in multiplication.
Example: [tex]x^2 + 3x + 4[/tex] is a polynomial consisting 3 terms as [tex]x^2 ,3x , \rm and \: 4[/tex]
If there is one term, the polynomial will be called monomial.If there are two terms, the polynomial will be called binomialIf there are three terms, the polynomial will be called trinomialThe given trinomial is [tex]x^2 + 4x + 3[/tex]
Since the tiles are added to be in unit and positive(1, 2, 3, or 4), thus, let it be denoted by z, then:
[tex]x^2 + 4x + 3 + z = (x+a)^2[/tex]
since z is added such that the specified trinomial becomes perfect square trinomial, and since its degree is 2, so it must be product of two linear polynomials, and since coefficient of x in given trinomial is 1, so we kept the coefficient of linear polynomial as 1
Now, expanding the obtained equation, and comparing the coefficients, we get:
[tex]x^2 + 4x + 3 + z = (x+a)^2\\x^2 + 4x + 3 + z = x^2 + a^2 + 2ax\\[/tex]
Thus, from comparison of coefficients of like terms and constants, we get:
[tex]2a = 4\implies a = 2\\3 + z = a^2 = 2^2 = 4\\z = 1[/tex]
Thus, the number of unit tiles needed to be added to the expression [tex]x^2 + 4x + 3[/tex] for making it perfect square trinomial is: Option A: 1

12. Daniel's BAC, B, after drinking can be determined using the formula B = 0,08 -0.016N,
where N is the number of hours that have elapsed since drinking. What is Daniel's BAC
after 3 hours and 15 minutes?
Step-by-step explanation:
B = 0.08 - 0.016N
N = 3 hours 15 minutes = 3.25 hours (= 3 1/4).
so, we get
B = 0.08 - 0.016×3.25 = 0.08 - 0.052 = 0.028

Solve the simultaneous equations
3x + y = 25
2x – y = 10
Answer:
x=7 and y=4
Step-by-step explanation:
I will use the elimination method:
Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:
3x + y =25
+ + +
2x - y = 10
Simplify:
5x=35
Divide both sides by 5:
5x÷5=35÷5
Simplify:
x=7
Substitute this into either equation 1 or 2 ( I chose 1):
3(7) + y = 25
21 + y = 25
Subtract 21 from both sides and simplify to get y:
21+y-21=25-21
y=4
Therefore x=7 and y=4

Answer:
%17.70
Step-by-step explanation:
18% of $15 is $2.70
$15+$2.70=$17.70
Answer:
Tip: $2.70
Total: $17.70
Step-by-step explanation:
To find the tip amount, we have to find 18% of 15.
18 × 15 = 270270/100 = 2.70 The tip amount is $2.70To find the total amount, we add the tip amount to the cost.
