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]

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]

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

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

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.

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.

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.

Using the probability concept and the Venn diagram described, the correct option is given by:

P(C|A) = 13/17.

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:

Hence:

P(A|B) = 7/20.

Following the same logic, we have that:

Hence the last option is correct.

Answer:

The value of x = 109°

angle PQS = 24°

Step-by-step explanation:

24° + 47° + x = 180° { angles on straight line }

=> 71 ° + x = 180°

=> x = 180° - 71°

=> x = 109°

Now,

Angle PQS = 24°

angle PQS = angle QSR { alternative angle }

Step-by-step explanation:

a)(i) x=109°

(ii)It's given that PST is straight line then PST=180°,and

PST=QSP+QSR+x

180° =47°+24°+x

180°=71°+x

180°-71°=x

109°=x

b)(i)PQS=71°

(ii)we know opposite angles are equal in parallelogram

so PSR=PQR=71°

Answer:

569.49$

Step-by-step explanation:

7.25% = .0725

530.99 x 0.725 = 38.50

530.99$ + 38.50$

569.49$

The exponential growth is 1.95% and after 35.72 years the population will double.

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.
