Answer:

  [tex]f^{-1}(x)=\pm\sqrt{x-10}[/tex]

Step-by-step explanation:

You can find the inverse of

  y = f(x)

by solving for y:

  x = f(y)

__

  x = y² +10

  x -10 = y² . . . . . . . . subtract 10

  ±√(x -10) = y . . . . . take the square root

The inverse relation is ...

  [tex]\boxed{f^{-1}(x)=\pm\sqrt{x-10}}[/tex]

__

It is not a function unless some restriction is placed on the domain of f(x).

Answer:

0 onto functions

Step-by-step explanation:

Let the sets be [tex]A\ and\ B[/tex] such that:

[tex]n(A) = 3[/tex]

[tex]n(B) = 8[/tex]

Required

The number of onto functions

The condition for onto functions is:

For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A

Since n(B) > n(A) i.e. 8 > 3

Then, there can't be onto functions from A to B

Answer:

108°

Step-by-step explanation:

hii!

lmn would be equal to 85 plus 23.

this is because those angles both make up the big angle lmn, so the answer is 108 degrees.

hope this helped you :)

m[tex]\angle{LMN[/tex] is 108°.

To form an angle we need at least two rays with one common endpoint this is also known as vertex of the angle.

There are many types of angles.For example - Acute angle, Obtuse angle, Right angle, complementary angle, Supplementary angle.

The most common unit for measuring an angle is in degrees and in radians,Where 1 rad = 180°.

According to the given question.

[tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex] are given they are 85° and 23° respectively.

From the given diagram we can observe that [tex]\angle{LMN[/tex] is sum of the angles [tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex].

∴ [tex]\angle{LMP[/tex] + [tex]\angle{PMN[/tex] = [tex]\angle{LMN[/tex]

     85° + 23° = 108°.

So, [tex]\angle{LMN[/tex] = 108°.

Step-by-step explanation:

14) sin45 = x/6 ---> x = 6sin45 = 4.24

cos45 = y/6 ---> y = 6cos45 = 4.24

15) Use sine law to solve for x, y and z.

[tex] \frac{x}{sin45} = \frac{25 \sqrt{2} }{sin60} \\ x = 25 \sqrt{2} \frac{sin45}{sin60} = 25 \sqrt{2} \frac{ \frac{ \sqrt{2} }{2} }{ \frac{ \sqrt{3} }{2} } \\ = \frac{50}{3} \sqrt{3} [/tex]

[tex]cos60 = \frac{y}{ \frac{50}{3} \sqrt{3} } \\ y = ( \frac{50}{3} \sqrt{3} )cos60 = ( \frac{50}{3} \sqrt{3} ) (\frac{ \sqrt{3} }{2} ) \\ y = 25 [/tex]

[tex]cos45 = \frac{z}{25 \sqrt{2} } \\ z = (25 \sqrt{2} )cos45 = (25 \sqrt{2} )( \frac{ \sqrt{2} }{2} ) \\ = 25[/tex]

Check whether the two expressions 2x+3y2x+3y and 2y+3x2y+3x equivalent.

The first expression is the sum of 2x2x 's and 3y3y 's whereas the second one is the sum of 3x3x 's and 2y2y 's.

Let us evaluate the expressions for some values of xx and yy . Take x=0x=0 and y=1y=1 .

2(0)+3(1)=0+3=32(1)+3(0)=2+0=22(0)+3(1)=0+3=32(1)+3(0)=2+0=2

So, there is at least one pair of values of the variables for which the two expressions are not the same.

Answer:

960

Step-by-step explanation:

80% = 0.8

0.8 * 1200 = 960

Answer:

960

how: 80% = 0.8 then: 0.8 * 1200 = 960

Answer:

Triangles always have 180°, split in some manner between the three angles. With two of the three angles given, you can set up a relatively simple equation, where the third angle is assigned to the variable x:

45°+85°+x=180°

130°+x=180°

x=50°

Answer:

3. (-3,4)    x=-3, y=4

Step-by-step explanation:

1. 3x-y=-13

  -y=-13-3x

  y=13+3x

2. 4x+2y=-4

   4x+2(13+3x)=-4

   4x+26+6x=-4

    10x+26=-4

    10x=-4-26

    10x=-30

    x=-30/10

    x=-3

3.  y=13+3x

    y=13+3(-3)

    y=13-9

Answer:

6561

Step-by-step explanation:

So, lets just go over what we know:

The exponent is 4, meaning the number will be multiplyied by itself 4 times.

The number is -9, so we are going to multiply it by -9, 4 times.

We can think of it like this:

9*9*9*9

I used postive nines instead of negative nine since the sign will be postive.(Because its a even exponent)

Now lets solve:

9*9*9*9

=

81*9*9

=

729*9

=

6561

So this is the answer!
