Answer: The values of both x and y will be real numbers greater than or equal to 0
Step-by-step explanation: because pounds and price cannot be a negative amount here. So either you're buying 0 or buying more than 0.
The thing that best describes the values of x and y is that they will be real numbers greater than or equal to 0

Step-by-step explanation:
For a quadratic equation y = ax² + bx + c, the vertex (the maximum or minimum point) is at x = -b/(2a).
1) y = -0.5t² + 2t + 38
The maximum is at:
t = -2 / (2 × -0.5)
t = 2
The maximum height is:
y = -0.5(2)² + 2(2) + 38
y = 40
The coordinates of the vertex are (2, 40). That means the missile reaches a maximum height of 40 km after 2 minutes.
2) y = -4.9t² + 12t + 1.6
The maximum is at:
t = -12 / (2 × -4.9)
t = 1.22
The maximum height is:
y = -4.9(1.22)² + 12(1.22) + 1.6
y = 8.95
The coordinates of the vertex are (1.22, 8.95). That means the missile reaches a maximum height of 8.95 m after 1.22 seconds.
3) y = -0.04x² + 0.88x
The maximum is at:
x = -0.88 / (2 × -0.04)
x = 11
The maximum height is:
y = -0.04(11)² + 0.88(11)
y = 4.84
The maximum height of the tunnel is 4.84 meters.
The maximum width is when y = 0.
0 = -0.04x² + 0.88x
0 = -0.04x (x − 22)
x = 22
The maximum width is 22 feet.

Consider a problem where we are rolling 2 dices where each dice has 6 faces numbered from 1 to 6.Answer the following questions:(1) What is the sample space?(2) If the event we are interested in is the sum being 10, what would be the probability of observingsuch an event?(3) If the event we are interested in is the sum being 6, what would be the probability of observingsuch an event?
Answer:
1. See Explanation for Sample Space
2. [tex]P(10) = \frac{1}{12}[/tex]
3. [tex]P(6) = \frac{5}{36}[/tex]
Step-by-step explanation:
Given
Roll of Two die
Solving (1): The Sample Space
Represent the first dice with S1 and the second with S2
[tex]S_1 = \{1,2,3,4,5,6\}[/tex]
[tex]S_2 = \{1,2,3,4,5,6\}[/tex]
The sample space of both die is:
[tex]S = (1,1)(1,2)(1,3)(1,4)(1,5)(1,6)(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)[/tex][tex](4,1)(4,2)(4,3)(4,4)(4,5)(4,6)(55,1)(5,2)(5,3)(5,4)(5,5)(5,6)(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)}\}[/tex]
Solving (2): Probability of Sum being 10
First, we need to add the outcome of each roll in (1) above:
[tex]S = \{2,3,4,5,6,7, 3,4,5,6,7,8, 4,5,6,7,8,9, 5,6,7,8,9,10, 6,7,8,9,10,11 7,8,9,10,11,12\}[/tex][tex]n(S) = 36[/tex]
[tex]n(10) = 3[/tex]
The required probability is:
[tex]P(10)= \frac{3}{36}[/tex]
[tex]P(10) = \frac{1}{12}[/tex]
Solving (3): Probability of Sum being 6
[tex]n(S) = 36[/tex]
[tex]n(6) = 5[/tex]
The required probability is:
[tex]P(6) = \frac{5}{36}[/tex]

it will be upward
it can touch only once when it's like[tex]y=a|x-b|[/tex]

what appear to be the next two terms in this sequence
18, 24, 32, 128/3.....
Answer: 512/9 and 6,144/81
Step-by-step explanation:
The sequence is:
18, 24, 32, 128/3, ...
Now, is easy to see that it is not an arithmetic sequence, so we can jump to see if this is a geometric sequence.
To see this, we must see at the quotient of two consecutive numbers in the sequence, and that quotient must be the same for any pair of consecutive elements.
24/18 = 1.33...
32/24 = 1.33...
(128/3)/32 = 1.33....
The quotient is constant, then this is a geometric sequence.
Then we can write the n-th term as:
Aₙ = Aₙ₋₁*1.33...
And we first should write 1.33 in a way that is easier to use:
1.33... = 1 + 0.33...
The left side can be writen as:
0.33... = 0.33...*(10/10) = (3.3.../10)
Now we can subtract the initial number:
(3.33..../10) - 0.33... = 3/10 = 0.33...*(9/10)
0.33... = (3*10)/(9*10) = 30/90 = 3/9
then we have:
1.33... = (1 + 3/9) = (9/9 + 3/9) = (12/9)
Then the two next terms are:
(128/3)*(12/9) = 128*4/9 = (512/9)
And the next term is:
(512/9)*(12/9) = (6,144/81)
Then the first six terms are:
18, 24, 32, 128/3, 512/9, 6,144/81

in order to be invited to tutoring or extension activities a student's performance must be at least 20 points higher or lower than an average score is 105 which inequality represents P the scores for students who are eligible for tutoring or extension activities
Answer:
i think its p ≤ 85 or p ≥ 125
Step-by-step explanation:
p can be 85 and higher but can be passed 125 but it can be 125 which makes the equality signs have the line under them meaning less than or equal to, and could also mean greater than or equal to.
The inequality that represents P the scores for students who are eligible for tutoring or extension activities is p ≤ 85 or p ≥ 125.
What is an Average?Average is the mean of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.
The average score is 105
The score required for tutoring is at least 20 points higher than average
The score required for extension activities is at least 20 points lower than average
P is the scores for students who are eligible for tutoring or extension activities
Then p ≤ 105 -20 = p ≤ 85
p ≥ 105+20 = p ≥125
p ≤ 85 or p ≥ 125

Answer:
175°
Step-by-step explanation:
Since, [tex] \overrightarrow{BD} [/tex] is in the interior of [tex] \angle ABC[/tex]
[tex] \therefore m\angle ABC = m\angle ABD + m\angle CBD\\
\therefore (14x + 21)\degree = (2x + 3)\degree + 150\degree \\
\therefore (14x + 21)\degree = (2x + 153)\degree\\
\therefore 14x + 21 = 2x + 153\\
\therefore 14x - 2x = 153 - 21\\
\therefore 12x = 132\\
\therefore x = \frac{132}{12}\\
\therefore x = 11\\\\
m\angle ABC = (14x + 21)\degree\\
m\angle ABC = (14\times 11+ 21)\degree\\
m\angle ABC = (154+ 21)\degree\\

Nicole and her children went into a grocery store and she bought $6 worth of apples and bananas. Each apple costs $1 and each banana costs $0.50. She bought 4 times as many bananas as apples. By following the steps below, determine the number of apples, x,x, and the number of bananas, y,y, that Nicole bought.
Solve this linear system 28x + 44y = 964.40 21x + 33y = 723.30
28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0
