What is 8 percent of 33.52

Answer:

Step-by-step explanation:

The first one I would factor the difference of cubes on top and then cancel a common factor this would end up giving you sin^2(A/2)+sin(A/2)cos(A/2)+cos^2(A/2)

(the 1st+3rd term here actually equals 1)

now you have

1+sin(A/2)cos(A/2)

1+1/2*2sin(A/2)cos(A/2)    (this step was just to help show how I'm going to use the next identity)

1+1/2sin(A)                    (double angle identity for sine)

hint for the next one: I would multiply top and bottom by bottom's conjugate first

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.

Solve |5-8x| -7 < 8

Answer:

No

Step-by-step explanation:

To determine if the 3 sides form a right triangle.

Use the converse theorem of Pythagoras.

If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,

longest side = 14 and 14 ² = 196

9² + 12² = 81 + 144 = 225

Since 196 ≠ 225 the triangle is not right

Answer:

x = 7

Step-by-step explanation:

The property of a parallelogram is the opposite sides are congruent, hence

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:

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

Answer:

undefined

Step-by-step explanation:

A line with a slope of zero is a horizontal line parallel to the x- axis

Thus, a line perpendicular to it is a vertical line parallel to the y- axis, with an undefined slope.

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

Equation:

[tex]15=\dfrac{1}{2}x+8[/tex]

Student ticket price = $14

Step-by-step explanation:

An adult ticket = $15

Let a student ticket = $x

An adult ticket is half the price of a student ticket plus $8, then an adult ticket

[tex]=\$\left(\dfrac{1}{2}x+8\right)[/tex]

Equate the prices for the adult ticket:

Answer:

B) 3

Step-by-step explanation:

The parts on the right side are to figure out which one to use so since g(3) then you plug in 3 to the equations on the right to see which one is true. The one that it matches into then plug in 3 for x in the equation directly to the left of it:

3 ≥ 3 so 6 - (3) = 3

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]

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

Step-by-step explanation:

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:

D

Step-by-step explanation:

By definition:

rational number = fraction or decimals that are non-whole numbers

negative = well..... negative numbers have a minus (-) in front of them.

Looking at the options, only D has a fraction that has a (-).

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:

x= -10

Step-by-step explanation:

(3)8+ [tex]\frac{\sqrt{2x+29} }{3}[/tex]= 9(3) (multiply both sides by 3)

24+ [tex]\sqrt{2x+29}[/tex]= 27  (move the 24 to the right)

[tex]\sqrt{2x+29}[/tex]=27-24 (subtract)

([tex]\sqrt{2x+29}[/tex])²= 3²  (square both sides)

2x+29=9 (move the 29 to the other side)

2x=9-29 (subtract)

2x= -20 (divide both sides by 2)

x= -10

hope this helps and good luck! :)

Answer:

see explanation

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]
