Answer:

The minimum number of adult tickets required to be sold = 54

Step-by-step explanation:

Hello,

In this question, we have several variables which might confuse us here, so I'll have to break it down bit by bit.

The drama club must make a sale of $560 so as to cover cost for the event.

The seat capacity of the hall = 84

Cost of tickets for adult = $8

Cost of tickets for students = $4.50

Total number of students sold = 29

Let the number of adult ticket required = x.

(4.50 × 29) + (8 × x) = 560

130.5 + 8x = 560

8x = 560 - 130.5

8x = 429.5

Divide both sides by 8

X = 429.5 / 8

X = 53.6 approximately 54.

Minimum required number of adult tickets to be sold is 54.

(29 × 4.50) + (54 × 8) = $130.5 + $432 = $562.5

Answer:

(C)y=0

Step-by-step explanation:

An exponential function of the form [tex]f(x) = a (b^x) + c[/tex] always has a horizontal asymptote at y = c.

Given our function [tex]y=4^x[/tex]

Comparing with the form,  [tex]f(x) = a (b^x) + c[/tex], we observe that c=0.

Therefore, the exponential function has an asymptote at y=0.

The correct option is C.

Answer:

x = 15

Step-by-step explanation:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 +13 + 14 + 15 = 120

The number x is a positive integer.

Value of positive integer [tex]x[/tex] is equals to [tex]15[/tex].

" Integers is defined as collection of whole numbers and negative numbers."

Formula used

Sum of first [tex]'n'[/tex] natural numbers

[tex]S_{n} = \frac{n(n + 1)}{2}[/tex]

According to the question,

Given positive integers,

[tex]1 + 2 + 3 + ......... + x =120[/tex]

Substitute the value in the formula to get sum of positive integers,

[tex]\frac{x(x+ 1)}{2}=120\\\\\implies x^{2} +x =240\\\\\implies x^{2} + x-240 =0\\\\\implies x^{2} +16x-15x -240=0\\\\\implies x (x+16) -15 (x+16) =0\\\\\implies (x+ 16) (x-15) =0\\\\\implies x = -16 or x =15[/tex]

[tex]'x'[/tex] is a positive integer. [tex]x=-16[/tex] is not possible.

Hence, Value of positive integer [tex]x[/tex] is equals to [tex]15[/tex].

Answer:

The correct option is:

A) L'' (-4 , -4) , M'' (-1 , -4) , N'' ( -1 , 0) , O'' (-4 , 0)

Step-by-step explanation:

The following are the vertices of a rectangle LMNO

L (-4 , 6)

M (-1 , 6)

N (-1 , 2)

O (-4 , 2)

First we have to reflect it across x-axis

When we reflect a shape across x-axis, the x components of the points remain the same while y components change their signs. After reflection:

L' (-4 , -6)

M' (-1 , -6)

N' ( -1 , -2)

O' (-4 , -2)

After we translate it up by two units, we add +2 to y components of each reflected point.

L'' (-4 , -4)

M'' (-1 , -4)

N'' ( -1 , 0)

O'' (-4 , 0)

Hence, the correct option is A

Answer:

28

Step-by-step explanation:

Consider the expansion:

[tex]$(x+y)^2=\sum_{k=0}^{n} \binom{n}{k}y^{n-k}x^k$$[/tex]

[tex]$ \binom{n}{k}=\frac{n!}{(n-k)!k!}[/tex]

We have

[tex]$\left(x + y\right)^{8}=\sum_{k=0}^{8} \binom{8}{k} \left(y\right)^{8-k} \left(x\right)^k[/tex]

I'm sorry but I will not write and solve everything, typing LaTeX takes time. But that's the idea:

For [tex]k=0[/tex]

[tex]$\binom{8}{0} \left(y\right)^{8-0} \left(x\right)^{0}=\frac{8!}{(8-0)! 0!}\left(y\right)^{8} \left(x\right)^{0}=y^{8}[/tex]

For [tex]k=2[/tex]

[tex]$\binom{8}{2} \left(y\right)^{8-2} \left(x\right)^{2}=\frac{8!}{(8-2)! 2!}\left(y\right)^{6} \left(x\right)^{2}=28 x^{2} y^{6}[/tex]

[tex](x+y)^8={x}^{8} + 8{x}^{7}y + 28{x}^{6}{y}^{2} + 56{x}^{5}{y}^{3} + 70{x}^{4}{y}^{4} + 56{x}^{3}{y}^{5} + 28{x}^{2}{y}^{6} + 8x{y}^{7} + {y}^{8}[/tex]

Answer:

y = 2/3x

Step-by-step explanation:

The first step is to find the slope

Pick two points on the line (0,0) and (3,2)

m = (y2-y1)/(x2-x1)

    = (2-0)/(3-0)

    = 2/3

The y intercept is 0

Using the slope intercept form

y =mx+b  where m is the slope and b is the y intercept

y = 2/3 x +0

y = 2/3x

2/9 of the 45 marbles must be red.

2/9 * 45 = 10

Answer:

10

Step-by-step explanation:

let's make the number of red marbles x

so probability of getting red marbles is x/45

so;.

[tex] \frac{x}{45} = \frac{2}{9} [/tex]

[tex] 45 \times \frac{x}{45} = \frac{2}{9} \times 45[/tex]

The probability that more than 4 evenings will go by without Jason having to wash dishes after dinner is 0.06.

Step-by-step explanation:

We are given that Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner.

He repeats this 50 times and records the data on the table below;

Number of flips until getting heads                  Frequency

                        1                                                          21          

                        2                                                         18

                        3                                                          4

                        4                                                          4

                        5                                                          2

                        6                                                          0

                        7                                                           0

                        8                                                           1    

                     Total                                                     50    

Now, we have to find the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner.

This will happen only when the Number of flips until getting heads is 5, 6, 7 or 8 as only then Jason will have more than 4 evenings go by without washing dishes after dinner.

So, required probability =  [tex]\frac{2}{50}+\frac{0}{50}+\frac{0}{50}+\frac{1}{50}[/tex]

                                        =  [tex]\frac{3}{50}[/tex]  = 0.06

Step-by-step explanation:

Refer to picture.

When graph of y = x is transformed to y = x - 13,

U can visualise it by drawing the before and after transformed graphs to compare in order to deduce the answer.

From the picture, you will realise that when x is unchanged, I'm this case I'm using points x=0 and x=13, the value of the y coordinate in the transformed graph (y = x-13) actually decreased by 13 units as compared to the original graph of y=x.

Hence the graph actually got translated 13 units in the direction of negative y axis which is option D

As per the translation of a graph, the given graph y= x is translated 13 units  to the right.

"The translation of a graph is its rigid movement, vertically or horizontally."

The given equation of the graph is: y = x.

The equation of the translated graph is: y = x - 13.

We know, the translation of a graph from y = f(x) to y = f(x - a) is translating the graph to the right by 'a' units.

Therefore, the given graph y= x is translated 13 units to the right.

(x - 8)² + (y+6)² + (z-6)²= 36

Step-by-step explanation:

To find the equation for a sphere with the center (8,-6,6) and radius 6, we will follow the steps below;

first write down the standard equation of a sphere:

(x - h)² + (y-k)² + (z-l)²= R²

where h, k and l are the center  and  R is the radius

From the question given, h = 8, k =-6  l=6  and R=6

we can now substitute the values into the formula

(x - h)² + (y-k)² + (z-l)²= R²

(x - 8)² + (y+6)² + (z-6)²= 6²

(x - 8)² + (y+6)² + (z-6)²= 36

Therefore, the equation for a sphere with the center (8,-6,6) and radius 6  is

(x - 8)² + (y+6)² + (z-6)²= 36

Answer:

x = -3   and   y = -4

x + y = -3-4 = -7

Step-by-step explanation:

-4x + 9y = -11 ------------------------------------------------------------------------(1)

-3x + 7y = -9--------------------------------------------------------------------------(2)

multiply through  equation (1) by 3   and multiply through equation(2) by 4

-12x + 27y = -33 -----------------------------------------------------------------------(3)

-12x + 28y   = -36 ----------------------------------------------------------------------(4)

subtract equation (1) from equation (2)

y = -3

substitute y = -3 into equation (2)

-3x + 7(-3) = -9

-3x -21 = -9

add 21 to both-side of the equation

-3x -21 + 21 = -9 + 21

-3x = 12

divide both-side of the equation by -3

-3x/-3 = 12/-3

x = -4

x = -3   and   y = -4

Answer:

D

Step-by-step explanation:

Answer:

D. 1.

Step-by-step explanation:

We know that the powers of the imaginary constant, i, follow a certain pattern.

i^1 = i, i^2 = -1, i^3 = -i, i^4 = 1.

Every 4 powers, the result cycles back to the original i. This is because there are only 4 unique digits that result from raising i to various powers.

To figure a higher power, such as 12, we need to take the remainder of the power when divided by 4 (the amount of unique answers), to simplify it to the original 4 powers.

So when you have i^12 power, the remainder is 0. This is because 4 is a factor of 12. As a result, we can simplify this to i^8, and therefore i^4, which equals 1.
