Answer:

[tex] 4 \sqrt{5} [/tex]

Step-by-step explanation:

By geometric mean property:

[tex]y = \sqrt{16 \times 4} \\ \\ y = \sqrt{64} \\ \\ y = 8 \\ \\ by \: pythagoras \: theorem: \\ \\ {z}^{2} = {y}^{2} + {4}^{2} \\ \\ {z}^{2} = {8}^{2} + {4}^{2} \\ \\ {z}^{2} = 64 + 16 \\ \\ {z}^{2} = 80 \\ \\ z = \sqrt{80} \\ \\ z = \sqrt{16 \times 5} \\ \\ z = 4 \sqrt{5} [/tex]

Answer:

tan 19° = 0.3443

Step-by-step explanation:

Value Of Trigonometric Functions

The value of the tangent of 19° cannot be expressed in exact form, that it, as a function of radicals or known constants as pi.

We need to use a calculator, computer, or similar technology to find the required value. We use a scientific calculator to get:

tan 19° = 0.3443

To the nearest ten-thousandth

x = number of additional tiers

(edited to be in the proper order)

Answer:

x=8 and y=23

Step-by-step explanation:

Rewrite equations:

y=2x+7;y=3x−1

Step: Solve y=2x+7 for y:

y=2x+7

Step: Substitute 2x+7 for y in y=3x−1:

y=3x−1

2x+7=3x−1

2x+7+−3x=3x−1+−3x(Add -3x to both sides)

−x+7=−1

−x+7+−7=−1+−7(Add -7 to both sides)

−x=−8−x−1=−8−1

(Divide both sides by -1)

x=8

Step: Substitute 8 for x in y=2x+7:

y=2x+7

y=(2)(8)+7

y=23(Simplify both sides of the equation)

Answer:

1380 children and 820 adults went to the zoo that day

Step-by-step explanation:

System of Equations

Define the following variables

x = number of children that went to the zoo

y = number of adults that went to the zoo

On a certain day,  2000 people went to the zoo, thus:

x + y = 2000

Solving for x:

x = 2000 - y        [1]

The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:

1.50x + 4y = 5050       [2]

Substituting x from [1]:

1.50(2000 - y) + 4y = 5050

Operating:

3000 - 1.50y + 4y = 5050

3000 + 2.5y = 5050

Subtracting 3000

2.5y = 5050 - 3000 = 2050

Dividing by 2.5

y = 820

From [1]

x = 2200 - 820 = 1380

1380 children and 820 adults went to the zoo that day

Answer:

C, 100 degrees

Step-by-step explanation:

180-80=100

Answer:

Step-by-step explanation:

d

Step-by-step explanation:

first do the x, you see x^2-8x so you first want to do (x-4)^2. But then you will see we have created an +16 so wee -16 and then we get (x-4)^2+y^2-9. There is no y to the first power term, therefore you choose d after moving 9 to the Right hand side.

Answer:

 (x + 5) • (x + 3) • (x - 2) • (x - 4)

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

     -3    +    -5    =    -8

     -1    +    -15    =    -16

     1    +    15    =    16

     3    +    5    =    8    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  3  and  5

                    x2 + 3x + 5x + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x+3)

             Add up the last 2 terms, pulling out common factors :

                   5 • (x+3)

Step-5 : Add up the four terms of step 4 :

                   (x+5)  •  (x+3)

            Which is the desired factorization

 (x + 5) • (x + 3) • (x - 2) • (x - 4)

x is always +3 ahead (30-27=3)

and y is always trailing behind x by -3

Answer:

y = x - 3

Step-by-step explanation:

You are given an x and a y and need to find the difference.

Set up a formula using one of the given x and y pairs and solve.

y = x - u  plug in an x and y and solve for the unknown(u)

27 = 30 - u

-3 = -u

u = 3

Now plug the unknown into the original equation

y = x - 3

Answer:

4x-20

Step-by-step explanation:

Answer:  its 2

Step-by-step explanation:

14 can only = 1 x 14

                  & 2 x 7

0-192 29-17

Equation can be solced to find t

Answer: y=1/2x+3

m is the slope in the equation y=mx+b. you find b by plugging in (8,7) into the equation y=1/2x+b. Plug in 7 for y and 8 for x. The equation will look like 7=1/2(8)+b. solve for b. b should equal 3.

so your answer is y=1/2x+3
