Answer:

B) [tex]y=sin(x+\frac{\pi}{2})[/tex]

Step-by-step explanation:

Technically, since the function starts at its maximum, you could say the function is [tex]y=cos(x)[/tex], but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity [tex]cos(x)=sin(x+\frac{\pi}{2})[/tex] and we can see that the correct answer is B.

The equation matches the function provided in the graph is y = sin(x + π/2) option (B) is correct.

It is defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.

It is given that:

A graph of a trigonometric function is given:

As we know,

y = sinx has a sinusoidal graph

Based on the graph we can apply a transformation to get the required function.

Applying transformation:

x → x + π/2

The sin function will shift left side by π/2 unit

The equation of the function becomes:

y = sin(x + π/2)

The equation of the function shown in the graph is y = sin(x + π/2)

Thus, the equation matches the function provided in the graph is y = sin(x + π/2) option (B) is correct.

Using a system of equations, it is found that Ajay is 25 years old today.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Wale was twice as old as Ajay 10 years back, hence:

[tex]x - 10 = 2(y - 10)[/tex]

[tex]x - 10 = 2y - 20[/tex]

Based on the system of equations, it is found that Ajay is 25 years old today.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

Based on the given information, we can say

Let Wale's age be x

Let Ajay's age be y

Ten years ago,

Wale = x - 10

Ajay = y - 10

If wale was twice as old as Ajay 10 years back, then;

x - 10 = 2(y - 10)

Since Wale will be 40 years old in 10 years, then;

x + 10 = 40

x = 40 - 10

x = 30

Recall that x - 10 = 2(y - 10)

30 - 10 = 2(y - 10)

20 = 2(y-10)

y = 20

Hence Ajay will be 20 years old today

Step-by-step explanation:

Given:

log_(a) abc = x+1,

log_(b) abc = y+1,

log_(c) abc =z+1

Asked: x + y + z + 2 = ?

Solution:

Let

log_(a) abc = x+1 ⇛log_(abc) a = {1/(x+1)} →→→Eqn(1)

log_(b) abc = y+1 ⇛log_(abc) b = {1/(y+1)} →→→Eqn(2)

log_(c) abc = z+1 ⇛log_(abc) c = {1/(z+1)} →→→Eqn(3)

On adding equation (1),(2) and (3) then

log_(abc) a + log_(abc) b + log_(abc) c = {1/(x+1) + {1/(y+1)} + {1/(z+1)}

⇛log_(abc) abc = {{(y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)}/{(x+1)(y+1)(z+1)}]

⇛1 = {{(y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)}/{(x+1)(y+1)(z+1)}]

⇛{(x+1)(y+1)}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛{x(y+1)+1(y+1)}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛{xy + x + 1 + y}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛{xy + x + y + 1}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛z(xy + x + y + 1) + 1(xy + x + y + 1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛xyz + xz + yz + z + xy + x + y + 1 = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛xyz + xz + yz + z + xy + x + y + 1 = y(z+1)+1(z+1) + z(x+1)+1(x+1) + x(y+1)+1(y+1)

⇛xyz + xz + yz + z + xy + x + y + 1 = yz + y + z + 1 + xz + z + x + 1 + xy + x + y + 1

⇛x+y+z = y + z + 1 + x + 1

⇛x+y+z = x + y + z + 2

Therefore, x + y + z + 2 = x + y + z

Answer: Hence, the value of x + y + z + 2 = x + y + z.

Answer:

  y = x² +10x -9

Step-by-step explanation:

A spreadsheet or suitable calculator can help you with this. All spreadsheets and most graphing calculators offer regression function capabilities. It is a good idea to learn to use these tools.

The attached graphing calculator output shows the equation to be ...

  y = x² +10x -9

_____

Additional comment

If you want to do this by hand, you recognize that there are only two coefficient values that need to be found. You can choose any two of the given points to use to create equations for those coefficients. I would choose the points with the x-values that are smallest in magnitude.

Using (-4, -33)

  y = x² +bx +c

  -33 = (-4)² +(-4)b +c

  -4b +c = -49 . . . . . . . . . subtract 16

Using (1, 2)

  2 = (1)² +(1)b +c

  b +c = 1 . . . . . . . . . . . . subtract 1

Now, we can subtract the first equation from the second ...

  (b +c) -(-4b +c) = (1) -(-49)

  5b = 50 . . . . . . . . simplify

  b = 10 . . . . . . . . . . divide by 5

Using the second equation, we get

  10 +c = 1

  c = -9 . . . . . . subtract 10

So, the desired quadratic is ...

  y = x² +10x -9

__

These equations are usually pretty easy to solve, because the 'c' variable has a coefficient of 1 in all of them. It can easily be eliminated by subtracting one equation from another. Here, we chose our subtraction so the coefficient of 'b' would end up being positive. (Not necessary, but can help prevent mistakes.)

If you don't know ahead of time that the coefficient of x² is 1, then you need to write 3 equations in the three coefficients.

Step-by-step explanation:

You need to concern yourself with the +3. That will determine what the equal roots are.

(2x + √3)^2

Now expand this to see what p is. (Kind of a nasty question if you ask me).

4x^2 + 2x*√3 + (√3)^2

4x^2 + 2√3 x + 3                 also possible is

4x^2 - 2√3 x + 3

So the answer is p = 2√3

The answer could also be p = -2√3

Answer:

  p = ±4√3

Step-by-step explanation:

The discriminant of quadratic equation ax²+bx+c = 0 is ...

  d = b² -4ac

In your quadratic, its value is ...

  d = p² -4(4)(3) = p² -48

The discriminant will be zero when the quadratic has equal roots. In that case, the values of p are found by ...

  d = 0

  p² -48 = 0

  p² = 48 . . . . . add 48

  p = ±√48 . . . . take the square root

  p = ±4√3 . . . . simplify

__

Another way to get there is by looking at the factoring of a quadratic with equal roots:

  (ax +b)² = 0 = a²x² +2ab +b²

Comparing to the given quadratic, we find ...

  a² = 4   ⇒   a = ±2 . . . . . . coefficient of x²

  b² = 3   ⇒   b = ±√3 . . . . constant

  p = 2ab = 2(±2)(±√3) . . . . coefficient of x

  p = ±4√3

The equation gives the ground distance in terms of the map distance, so would have to be solved for x to be used to find map distance.

The graph is not shown.

The table appears correct, and includes the value 32 km for a map distance of 4 cm. The ground distance of interest is 64 km, which is twice that table value. That means the map distance will be twice the corresponding table value: 2×4 cm = 8 cm.

81 adult tickets

Step-by-step explanation:

Step 1:

Set up a system of equations

Since the adult tickets and student tickets add to 243, we can do

[tex]a+s=243[/tex]

and the student tickets sold were 2x the adult tickets, we can do

[tex]s=2a[/tex]

We can replace s in the first equation adding to 243 with 2a

[tex]a+s(2a)=243\\3a=243\\[/tex]

Step 2:

Solve for a. We can divide both sides by 3.

[tex]a=81[/tex]

Therefore, there were 81 adult tickets sold.

Step 3:

We can check our work! Since we learned earlier the student tickets are 2x adult tickets, we can multiply 81 by 2 and add that to 81 to see if it equals 243!

[tex]s=2a\\s=2(81)\\s=162[/tex]

And...

[tex]162+81=243[/tex]

So, 81 must be the answer!
