If loga abc=x +1,
logb ab c=y+1, logc abc=z+1
then
x+
y+z
+2​

Answers

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.

Wale was twice as old as Ajay 10 years back. How old is Ajay today if Wale will be 40 years old 10. years hence?​

Answers

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

What is a system of equations?

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:

Variable x: Wale's age.Variable y: Ajay's age.

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

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

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

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

Wale will be 40 years old in 10 years, hence:

[tex]x + 10 = 40[/tex]

[tex]x = 40[/tex]

Then, Ajay's present age is found as follows.

[tex]2y = x + 10[/tex]

[tex]2y = 40 + 10[/tex]

[tex]y = \frac{50}{2}[/tex]

[tex]y = 25[/tex]

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

What is a system of equations?

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

A total of 243 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two
times the number of adult tickets sold. How many adult tickets were sold?

Answers

Answer:

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!

Find the values of p for which the quadratic equation 4x2 + px + 3 = 0 has equal roots.​

Answers

Answer:

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 attachment shows the two different values of p give equations with one solution (each).

T2=266°C

T2=266+273

T2=539K

25L/283K=T2/539K

T2=(25L×539K)/283K

T2=47.6L

Solution 1 :-

The measure of Angle SKR is 90°

In Rhombus, The diagonals bisect each other at 90° it means diagonals are perpendicular to each other.

Hence, Option C is correct

Solution 2 :-

The measure of Angle RAK is 32°

We have given that angle RAT is 64° but here AK is acting as a bisector of Angle RAT

Therefore,

[tex]\sf{\angle{RAT = 2 }} {\sf{\angle{RAK}}}[/tex]

[tex]\sf{\dfrac{ 64}{2}}{\sf{=}}{\sf{\angle{RAK}}}[/tex]

[tex]\sf{\angle{ RAK = 32°}}[/tex]

Hence, Option a is correct

Solution 3 :-

The measure of Angle ARS is 116°

Opposite angles of rhombus are equal

[tex]\sf{\angle{ARS = }}{\sf{\angle{ATS}}}[/tex]

So,

[tex]\sf{\angle{RSK = }}{\sf{\angle{RAK}}}[/tex]

[tex]\sf{\angle{ RSK = 32° }}[/tex]

By using Angle sum property

AngleRSA + AngleSAR + AngleARS = 180°

[tex]\sf{ 32° + 32° + }{\sf{\angle ARS = 180° }}[/tex]

[tex]\sf{\angle {ARS = 180° - 64° }}[/tex]

[tex]\sf{\angle{ARS = 116° }}[/tex]

Hence, Option d is correct

Solution 4 :-

The measure of angle KRS is 58°

We know that angle ARS is 116° but here RK is acting as a bisector of Angle ARS

Therefore ,

[tex]\sf{\angle{ARS}}{\sf{ = 2}}{\sf{\angle KRS}}[/tex]

[tex]\sf{\dfrac{ 116}{2}}{\sf{=}}{\sf{\angle{KRS}}}[/tex]

[tex]\sf{\angle{ KRS = 58°}}[/tex]

Hence, Option b is correct

Solution 5 :-

mAngleSKR = All of the above

In rhombus, the diagonals bisect each other at 90°

From Above, we can say that,

mAngleSKR + mAngleAKR + mAngleAKT + mAngleSKT = 90°

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.

What is sin function?

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.
