What is the following quotient?
sqr root 6 + sqr root 11/ sqr root 5+ sqr root 3

The new surface area of a square pyramid when its dimensions are multiplied by 1/3 is calculated by squaring the scale factor (1/3) and multiplying it with the original surface area. In this case, the new surface area is 121 in².

When the dimensions of a square pyramid are multiplied by 1/3, each linear dimension of the pyramid becomes one-third of its original size. Since surface area is a two-dimensional measure (length × width), when you scale down each dimension by a factor of 1/3, the new surface area will be the square of that scale factor times the original area. The surface area is proportional to the square of the scaling factor because area is calculated using two dimensions.

The original surface area is 1,089 in². To find the new surface area, we use the scale factor squared: (1/3) ² = 1/9. We then multiply the original surface area by this factor:

New Surface Area = Original Surface Area × (Scale Factor)²
New Surface Area = 1,089 in² × 1/9
New Surface Area = 1,089 in² / 9
New Surface Area = 121 in²

Therefore, the new surface area of the square pyramid when the dimensions are multiplied by 1/3 will be 121 in².

Answer:

First day: 45x +20y = 875

Second day: 25x + 40y = 775

Adult ticket price: $15

Step-by-step explanation:

See paper attached. (:

The system of equations that model this scenario is:

45x + 20y = $875 equation 1

25x + 40y = $775 equation 2

The price of adults tickets is $15. The price of student's ticket is $10.

In order to determine this value, multiplot equation 1 by 2 and subtract the resulting equation from equation 2.

90x + 40y = 1750 equation 3

975 = 65x

x = 15

Substitute for x in equation 1

45(15) + 20 = 875

675 + 20y = 875

y = (875 - 675) / 20

y = 10

the solutions are (x = 2) and (y = 4).

To find the values of x and y in the given equations, let's solve them step by step:

1. (3^{2x-y} = 1)

For any nonzero number raised to the power of 0, the result is always 1. Therefore, we can rewrite the equation as:

[2x - y = 0]

Now, we have one equation in terms of (x) and (y).

2.[tex]\( \frac{16^x}{4} = 8^{3x-y} \)[/tex]

We'll simplify the left side first:

[tex]\[ \frac{16^x}{4} = \frac{(4^2)^x}{4} = \frac{4^{2x}}{4} = 4^{2x-1} \][/tex]

Now, the equation becomes:

[4^{2x-1} = 8^{3x-y}]

We know that (8 = 2^3), so we can rewrite the right side of the equation in terms of 2:

[4^{2x-1} = (2^3)^{3x-y} = 2^{9x-3y}]

Now, we have:

[4^{2x-1} = 2^{9x-3y}]

Since (4 = 2^2), we can rewrite the left side as:

[ (2^2)^{2x-1} = 2^{4x-2} ]

So, the equation becomes:

[2^{4x-2} = 2^{9x-3y}]

Since the bases are the same, the exponents must be equal:

[4x - 2 = 9x - 3y]

Now, we have two equations:

[2x - y = 0]

[4x - 2 = 9x - 3y]

From the first equation, we can solve for (y):

[y = 2x]

Substituting (y = 2x) into the second equation:

[4x - 2 = 9x - 3(2x)]

[4x - 2 = 9x - 6x]

[4x - 2 = 3x]

[x = 2]

Now, substituting (x = 2) into the first equation to find (y):

[2(2) - y = 0]

[4 - y = 0]

[y = 4]

So, the solutions are (x = 2) and (y = 4).

Answer:

Step-by-step explanation:

Since the sequence is geometric then the common ratio (r) is

r = [tex]\frac{18}{24}[/tex] = [tex]\frac{3}{4}[/tex] = 0.75

To find the next term in the sequence, multiply the previous term by r

The next 3 terms are

18 × 0.75 = 13.5

13.5 × 0.75 = 10.125

10.125 × 0.75 = 7.59375

The n th term equation of a geometric sequence is

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term, that is a = 24, hence

[tex]a_{n}[/tex] = 24[tex](0.75)^{n-1}[/tex]

Answer:

An exponent value in a would make the system inconsistent because it will either gain or lose height over time.

Any real number without an exponent value will make the system consitent.

Any infintite/repeating number will make the system both consistent and inconsistent. it is consisent because it will stay at a constant rate but also inconsistent because it is repeating and will never end.

Answer:

When a = 3 and b ≠ 5, the system will be inconsistent because the lines will be parallel. When a = 3 and b = 5, the system will be consistent and dependent because they represent the same line.

Answer:

y = 5x + 29

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 2 is in this form with slope m = 5

• Parallel lines have equal slopes, hence

y = 5x + c ← is the partial equation of the parallel line

To find c substitute (- 6, - 1) into the partial equation

- 1 = - 30 + c ⇒ c = - 1 + 30 = 29, thus

y = 5x + 29 ← in slope- intercept form

Answer:

see explanation

Step-by-step explanation:

To find the y- intercept let x = 0

f(0) = 0² - 8(0) - 10 = 0 - 0 - 10 = - 10

The y- intercept is (0, - 10)

To find the x- intercepts let f(x) = 0, that is

2x² - 8x - 10 = 0 ( divide through by 2 )

x² - 4x - 5 = 0

Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

The factors are - 5 and + 1, since

- 5 × 1 = - 5 and - 5 + 1 = - 4, hence

(x - 5)(x + 1) = 0

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 1 = 0 ⇒ x = - 1

The x- intercepts are (- 1, 0) and (5, 0)

Final answer

The y-intercept of the function f(x) = 2x²8x-10 is at (0, -10), and the x-intercepts are (-1,0) and (5,0).

To determine the y-intercept and the other x-intercept of the quadratic function f(x) = 2x²-8x-10, we can use the standard forms and properties of quadratic equations.

The y-intercept occurs when x=0. Substituting x with 0 in the function, we get f(0) = 2(0)²- 8(0) - 10 = -10. Thus, the y-intercept is at (0, -10).

To find the other x-intercept given one of them as (-1,0), we can factor the quadratic equation, or use the quadratic formula. Factoring gives us:

(2x + 2)(x - 5) = 0

2x + 2 = 0 would give us an x-intercept at x = -1, which we already have. x - 5 = 0 gives us the other x-intercept at x = 5. So, the other x-intercept is at (5,0).

Answer:

Points to remember

The central angle of an arc is double the value of arc subtended on the the other part of the circle

From the figure we can see a circle with center F.

It is given that, mAB = mBC = mCD, means that, central angles of all these three arcs are equal.

To find the m<AFB

Fro the figure we get,m<CED = 15°

Therefore central angle of arc CD = 30°

So m<AFB = 30°

          3                                         1

          4                                         2

          5                                         1

          6                                         3    

          7                                          1

          9                                          1  

Hence, the total number of days= 2+1+2+1+3+1+1=11

Also, the number of days in which Omur's mother took 6 vitamins= 3

( Since there are 3 dots over 6)

Hence, the estimated probability that Omur's mom take exactly 6 vitamins tomorrow is:

Answer:

12,6

Step-by-step explanation:

The explicit rule for the arithmetic sequence on which the series is based is an = 12 + (n - 1)  * 6

Series are sum of sequences. The nth term of an arithmetic series is expressed as:

an = a + (n - 1)d

where

a is the first term = 12

n is the number of terms

d is the common difference = 18 - 12 = 24 - 18 = 6

Substitute

an = 12 + (n - 1)  * 6

Hence the explicit rule for the arithmetic sequence on which the series is based is an = 12 + (n - 1)  * 6

The absolute degree is obtained with the sum of the exponents of all the variables of each term. The terms are the elements of the polynomial with numbers and letters separated by addition or subtraction.

Step-by-step explanation:

[tex]x {}^{2} = 7x + 4[/tex]

It can also be written as:-

[tex]x {}^{2} - 7x - 4 = 0[/tex]

Now, here a=1, b= -7 and c = -4

Now by quadratic formula,

[tex]d = b {}^{2} - 4ac[/tex]

Calculate d which is

[tex] \sqrt{65} [/tex]

Now, the roots will be:-

[tex]x = ( - b + \sqrt{d} ) \div 2a[/tex]

and hence it will become:-

[tex]x = (7 + \sqrt{65} ) \div 2[/tex]

and

[tex] x = (7 - \sqrt{65} ) \div 2[/tex]

Answer: third option.

Step-by-step explanation:

Move the [tex]7x[/tex] and [tex]4[/tex] to the left side of the equation:

[tex]x^2 = 7x+ 4[/tex]

 [tex]x^2 -7x- 4=0[/tex]

Now you need to apply  the Quadratic formula:

[tex]x=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]

In this case you can identify that:

[tex]a=1\\b=-7\\c=-4[/tex]

Then you can substitute values into the Quadratic formula and get the following solutions:

[tex]x=\frac{-(-7)\±\sqrt{(-7)^2-4(1)(-4)} }{2*1}\\\\x_1=\frac{7-\sqrt{65} }{2}\\\\x_2=\frac{7+\sqrt{65} }{2}[/tex]

Answer:8

Step-by-step explanation:

Solving the given equation we get  [tex]\[ -\frac{5}{4} < x < \frac{5}{2} \][/tex]

1. We start by isolating the absolute value expression by adding 7 to both sides of the inequality.

2. Then, we split the inequality into two cases based on the inner expression of the absolute value: when [tex]\( 5 - 8x \)[/tex] is non-negative and when it is negative.

3. Solving each case separately, we find the range of values for [tex]\( x \).[/tex]

4. Finally, we combine the solutions from both cases to get the final solution: [tex]\( -\frac{5}{4} < x < \frac{5}{2} \).[/tex]This means that[tex]\( x \)[/tex]lies between -5/4 and 5/2.

To solve the inequality[tex]\( |5 - 8x| - 7 < 8 \)[/tex], we'll first isolate the absolute value expression and then solve for [tex]\( x \).[/tex]

1. Add 7 to both sides:

[tex]\[ |5 - 8x| < 15 \][/tex]

2. Now, we'll split the inequality into two cases based on the inner expression of the absolute value:

Case 1: [tex]\( 5 - 8x \geq 0 \)[/tex]

[tex]\[ 5 - 8x < 15 \][/tex]

[tex]\[ -8x < 10 \][/tex]

[tex]\[ x > \frac{10}{-8} \][/tex]

[tex]\[ x > -\frac{5}{4} \][/tex]

Case 2:[tex]\( 5 - 8x < 0 \)[/tex]

[tex]\[ -(5 - 8x) < 15 \][/tex]

[tex]\[ -5 + 8x < 15 \][/tex]

[tex]\[ 8x < 20 \][/tex]

[tex]\[ x < \frac{20}{8} \][/tex]

[tex]\[ x < \frac{5}{2} \][/tex]

So, we have two sets of solutions:

Case 1: [tex]\( x > -\frac{5}{4} \)[/tex]

Case 2:[tex]\( x < \frac{5}{2} \)[/tex]

Combining these two cases, we get:

[tex]\[ -\frac{5}{4} < x < \frac{5}{2} \][/tex]

1. We start by isolating the absolute value expression by adding 7 to both sides of the inequality.

2. Then, we split the inequality into two cases based on the inner expression of the absolute value: when \( 5 - 8x \) is non-negative and when it is negative.

3. Solving each case separately, we find the range of values for \( x \).

4. Finally, we combine the solutions from both cases to get the final solution: [tex]\( -\frac{5}{4} < x < \frac{5}{2} \).[/tex] This means that [tex]\( x \)[/tex] lies between -5/4 and 5/2.
