Answer:

Step-by-step explanation:

Assuming that the numbers went in a pattern instead of a random order it would be 48 because 48 divided by 3 would be 24. 24 would be the first number though, so it would be 48 because 24 plus 24 is 48.

Answer:

[tex]\sin (\frac{\pi}{12})=\frac{\sqrt{6}-\sqrt{2}}{4}[/tex]

Step-by-step explanation:

We want to find the exact value of

[tex]\sin \frac{\pi}{12}[/tex]

We rewrite the given expression to obtain:

[tex]\sin \frac{\pi}{12}=\sin (\frac{\pi}{3}-\frac{\pi}{4})[/tex]

We use the identity:

[tex]\sin (A-B)=\sin A \cos B-\sin B \cos A[/tex]

[tex]\sin ( \frac{\pi}{3}- \frac{\pi}{4})=\sin \frac{\pi}{3} \cos \frac{\pi}{4}-\sin \frac{\pi}{4} \cos \frac{\pi}{3}[/tex]

[tex]\sin ( \frac{\pi}{3}- \frac{\pi}{4})=\frac{\sqrt{3}}{2} \times \frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2} \times \frac{1}{2}[/tex]

[tex]\sin ( \frac{\pi}{3}- \frac{\pi}{4})=\frac{\sqrt{6}-\sqrt{2}}{4}[/tex]

The exact value of sin(π/12) is ±√(2 - √3)/2 by using half-angle formula

To find the exact value of sin(π/12), we can use the half-angle formula for sine:

sin(x/2) = ±√[(1 - cos(x))/2]

In this case, x = π/6.

Therefore, we can use the half-angle formula with x = pi/6 to find the exact value of sin(π/12).

sin(pi/12) = ±√[(1 - cos(π/6))/2]

Let's calculate the value step by step:

cos(π/6) = √3/2

sin(π/12) = ±√[(1 - √3/2)/2]

To simplify further, let's rationalize the denominator:

sin(π/12) = ±√[(2 - √3)/4]

sin(π/12) = ±√(2 - √3)/2

Therefore, the exact value of sin(π/12) is ±√(2 - √3)/2.

Answer:

Step-by-step explanation:

Given:  f(x)=5x^3-51x^2+77x+100/x^2-11x+24

Please use parentheses to eliminate any ambiguity:

      f(x) = (5x^3-51x^2+77x+100) / (x^2 - 11x + 24)

or (better yet):

                  5x^3-51x^2+77x+100

        f(x) = ---------------------------------

                      x^2 - 11x + 24

The vertical asymptotes here are at the zeros of the denominator:

x^2 - 11x + 24 = 0,  This quadratic equation has coefficients a = 1, b = -11 and c = 24.  Thus, its roots (zeros) are:

       -(-11) ± √( 121 - 4(1)(24) )

x = -------------------------------------

                    2(1)

or:

        11 ± √( 25 )

x = --------------------

                 2

or:  x = 8 and x = 3

The vertical asymptotes are x = 8 and x = 3.

If we attempt to divide x^2 - 11x + 24 into 5x^3 - 51x^2 + 77x + 100, we see that the first term of the quotient is 5x.  As x increases or decreases without bound, 5x goes to either ∞ or -∞, so we conclude that there is no horiz. asymptote.  Continuing this division results in:

5x + 4 + a fraction

This represents the slant asymptote, y = 5x + 4

-x = 2y

-x = 2(x+3)

-x = 2x + 6

x = -2

Substitute x=-2 into equation 2

y = x+3

y = -2+3

____________________________________________________

Answer:

Your answer would be 0.343.

____________________________________________________

Step-by-step explanation:

In the probability questions like this one, in order to get the answer,we would use the multiplication rule.

In your questions, we are trying to find the probability of ALL of your friends going to the mall with you.

Lets make it easier for you.

Whenever in probability you can say and, you multiply.

This means that you would try to find if friend 1 and friend 2 and friend 3 will say yes.

That's the same as saying friend 1's probability × friend 2's  probability × friend 3's  probability

We know that each friend has a 0.70 chance of saying yes.

Using the multiplication rule, we would just multiply 0.7 three times.

[tex]0.7 *0.7*0.7=0.343[/tex]

When you multiply, you should get 0.343.

There is a 0.343 chance of ALL your friends saying yes to go to the mall with you.

0.343 would be your FINAL answer.

____________________________________________________

To solve this problem, you need to consider the probability of each friend agreeing to go to the mall individually, then multiply these probabilities together to find the probability that all three will say yes.
Since each friend has a 0.70 chance of saying yes, we can calculate the combined probability as follows:
For the first friend, the probability is 0.70.
For the second friend, the probability is also 0.70.
For the third friend, the probability remains 0.70.
To find the combined probability that all three friends will say yes, we multiply the individual probabilities together:
\( Probability (All Say Yes) = Probability (Friend1 says Yes) \times Probability (Friend2 says Yes) \times Probability (Friend3 says Yes) \)
\( Probability (All Say Yes) = 0.70 \times 0.70 \times 0.70 \)
When you calculate this, you get:
\( Probability (All Say Yes) = 0.343 \)
So the answer is c. 0.343.

Step-by-step explanation:

Polygon ABCD is a kite. The area of a kite is equal to the product of the diagonals divided by 2.

One diagonal is segment AC.

AC = AE + CE = 2 + 2 = 4

The other diagonal is segment BD.

BD = BE + ED

BD = BE + 2BE

BD = 3BE

BD = 3(2) = 6

The diagonals measure 4 inches and 6 inches.

area = diagonal1 * diagonal2/2

area = 4 * 6 /2

area = 24/2

area = 12

However, point slope equations can be awkward to use in some algebraic operations. In such cases, it may be helpful to convert the equation into a different form, the standard form. The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers.

Answer:

Total = Principal * (1 + 6%/2)^2*years

Total = 11,000 * (1.03)^2*10

Total = 11,000 * (1.03)^20

Total = 11,000 * 1.8061112347

Total = 19,867.22

Step-by-step explanation:

It is -10

Because when you take two points from the table and put it into the equation y=my+b...

So for example, take (-4,-16) from the table and substitute into x and y...

-16=m(-4) + b

And then substitute all the options given in the question, so I tried -10 first and put it in the place of m( in the equation) because m is the slope.

Then the equation would look like this:

-16= -10(-4) +b

Now solve for b

B= 24

And then check your answer by the RHS and LHS Method..

-16=-40 +24

Which is equal to:

-16=-16

There fore the the slope of this equation is 10

Answer: 5

Step-by-step explanation:

From the given table in picture,

Take [tex]x_1=0\ ;\ y_1=4\\\\x_2=2\ ;\ y_2=14[/tex]

Then, slope of the given function will be given by :-

[tex]\text{Slope}=\dfrac{14-4}{2-0}\\\\\Rightarrow\text{Slope}=\dfrac{10}{2}=5[/tex]

3x+4=22

Step-by-step explanation

So, if you minus 4 from 22 and divided by 3, there will be the answer for x. Which is 6.

The equation that could be formed using the letter x to be represent the unknown number is 3x + 4 = 22

let

x = the unknown number

multiply it by three

= x × 3

= 3x

add four

3x + 4

I get twenty two

3x + 4 = 22

solve for x

3x = 22 - 4

3x = 18

x = 18/3

x = 6

Therefore, the unknown number in the equation 3x + 4 = 22 is 6

check:

3x + 4 = 22

3(6) + 4 = 22

18 + 4 = 22
