Answer:
[tex]\textsf{a)} \quad P=-20(x-2)^2+3380[/tex]
b) cost of ticket = $13
max profit = $3380
number of tickets sold = 260
Step-by-step explanation:
Profit equation: [tex]P=20(15-x)(11+x)[/tex]
Part (a)Vertex form of quadratic equation: [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex and [tex]a[/tex] is some constant)
First, write the given profit equation in standard form [tex]ax^2+bx+c[/tex]:
[tex]\begin{aligned}\implies P&=20(15-x)(11+x)\\& = 20(165+4x-x^2)\\& = -20x^2+80x+3300\end{aligned}[/tex]
Factor -20 from the first two terms:
[tex]\implies P=-20(x^2-4x)+3300[/tex]
Complete the square:
[tex]\implies P=-20(x^2-4x+4)+80+3300[/tex]
[tex]\implies P=-20(x-2)^2+3380[/tex]
Part (b)The vertex of the profit equation is (2, 3380).
Therefore, the cost of the ticket is when x = 2 ⇒ $11 + 2 = $13
The maximum profit is the y-value of the vertex: $3380
The number of tickets sold at this price is:
⇒ max profit ÷ ticket price
= 3380 ÷ 13
= 260

The actual height in inches,will be [tex]\dfrac{1}{6} c[/tex] of one of her friends who is c centimeters tall in the picture
What is hieght?Height is measure of vertical distance, either vertical extent (how "tall" something or someone is) or vertical position.
lets call the height x :
[tex]\dfrac{10}{60} = \dfrac{h}{x}[/tex]

Question 22: 4 pts Find the probability of rolling a 4 on a number cube and then choosing a red ball at random from a bag of 8 blue and 6 red balls.
Answer:
1/14
Step-by-step explanation:
a four out of possible 6 rolls = 1/6
6 red out of 14 balls 6/14
1/6 * 6/14 = 1/14
The Probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.
What is Probability?Probability is "possibility that deals with the chance of occurrence of random event" .
According to the question,
A cube has 6 faces that is (1,2,3,4,5,6). Total number of faces n(s) = 6.
Probability formula = (Number of favorable event)/(Total number of event).
Probability of taking 4, P(4) = 1/6.
A bag containing 8 blue and 6 red balls. Total number of balls in a bag n(s) = 14.
Probability of taking red balls P(red balls) = 6/14.
In order to find that probability of rolling a 4 on a number cube and then choosing a red a ball at random only if multiply P(4) by P(red balls).
P(4) × P(red balls) = [tex]\frac{1}{6}[/tex] × [tex]\frac{6}{14}[/tex] = [tex]\frac{1}{14}[/tex].
Hence, probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.

Please I really need help
Answer:
85°
Step-by-step explanation:
The two angles are known as vertical angles, which are always congruent
Answer:
∠DEB = 85°
Step-by-step explanation:
Vertical Angle Theorem
When two straight lines intersect, they form two pairs of angles. The vertically opposite (non-adjacent) angles are congruent.
Angles AEC and DEB are vertically opposite angles, therefore:
∠AEC = ∠DEB
As ∠AEC = 85° then ∠DEB = 85° also.
14 2/3 yards into feet?
Answer:
44.000000001 (exact) or rounded up 44
Step-by-step explanation:
14.666666667*3 because 1 yard= 3 feet
One yard is 3 feet, which means we will have to mutliple 14 2/3 by 3.
14 x 3 =42
2/3 of a yard is 2 feet, which means we must add 2 to 42--->
42+2= 44
14 2/3 yards is 44 feet.

What is the value of the expression below when f = 2.5
8 + 4f
A. 132
B. 18
C. 42
D. 28
Answer:
x = 48
Step-by-step explanation:
(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰
x - 6⁰ + 2x + 42⁰ = 180⁰
x + 2x - 6⁰ + 42⁰ = 180⁰
3x + 36⁰ = 180⁰
3x + 36⁰ - 36⁰ = 180⁰ - 36⁰
3x = 144⁰
3x / 3 = 144⁰ / 3
x = 48

For each set of three measures, determine if they can be angle measures of a triangle.
Angles Can be angle measures of a triangle Cannot be angle measures of a triangle
The sum of the angles in the triangle must be equals to 180 degrees for it to be the angle measure of a triangle.
Angles in a triangle
The sum of angles in a triangle is equals to 180 degrees.
Therefore, adding up the three angles in a triangle must be equals to 180 degrees.
Hence,
42 + 34 + 56 = 132 degrees
This does not form a triangle.
35 + 80 + 65 = 180 degrees
This can be the angle measure of a triangle.
15 + 51 + 24 = 90 degrees
This cannot be the angle measure of a triangle.
18 + 42 + 120 = 180

Use the Venn diagram to calculate probabilities.
Circles A, B, and C overlap. Circle A contains 3, circle B contains 9, and circle C contains 6. The overlap of A and B contains 1, the overlap of B and C contains 4, and the overlap of C and A contains 7. The overlap of the 3 circles contains 6. Number 8 is outside of the circles.
Which probability is correct?
P(A|B) = One-half
P(B|A) = StartFraction 7 Over 20 EndFraction
P(A|C) = StartFraction 6 Over 23 EndFraction
P(C|A) = StartFraction 13 Over 17 EndFraction
Using the probability concept and the Venn diagram described, the correct option is given by:
P(C|A) = 13/17.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
P(A|B) is given by the sum of the values that involve both A and B by the sum of all values that involve B, hence:
D = 1(overlap of A and B) + 6(Overlap of the 3).T = 9 + 1 + 4 + 6 = 20.Hence:
P(A|B) = 7/20.
Following the same logic, we have that:
P(B|A) = (1 + 6)/(3 + 1 + 7 + 6) = 7/17P(A|C) = (7 + 6)/(6 + 4 + 7 + 6) = 13/23P(C|A) = (7 + 6)/ (3 + 1 + 7 + 6) = 13/17.Hence the last option is correct.

In 1900 Kansas City had a population of 163,000In 2020 it has a population of 1,686,000Show me exponential growthHow many years after 1900Did it take for the population to double
The exponential growth is 1.95% and after 35.72 years the population will double.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential growth function is:
[tex]\rm y = Ae^{rt}[/tex]
A = 163,000
y = 1,686,000
t = 2020 – 1900 = 120 years
Plug all the values in the function:
[tex]\rm 1686000 = 163000e^{120r}[/tex]
[tex]\rm e^{120r} = 10.343[/tex]
Taking ln both side and solving:
r = 0.0194
r = 1.946 ≈ 1.95%
[tex]\rm 2A = Ae^{0.0194t}[/tex] (the population to double)
After solving:
t = 35.72 years
Thus, the exponential growth is 1.95% and after 35.72 years the population will double.
