Step-by-step explanation:

Tenth is the first digit after decimal sign

Given number is:

Since the next digit after the tenth digit is 9>5, we add 1 to tenth digit and drop the rest digits on the right of digit 2

So we get:

Answer:

((-1, 2), (1, 3), (1, 5), (-3, 4))

Step-by-step explanation:

For a set of ordered pairs to be considered a function, a domain value should have exactly just 1 range value.

If a domain value is having more than 1 range value assigned to it, it is not a function. In order words, an x variable value should have exactly just one y variable value assigned to it.

x variables are domain values while y variables are the range values.

In the ordered pairs, ((-1, 2), (1, 3), (1, 5), (-3, 4)), the two pairs, (1, 3), (1, 5), have the same x variable value with different y-variable values assigned to each. This renders the set of ordered pairs not to be a function. Domain value 1, is having different range value of 3 and 5.

Answer:

Product 1, because the function is exponential.

Step-by-step explanation:

If you take set the equation to 9 years. You will see that product one would be 2^9 = 512 and Product 2 would be 9^2 + 12 = 93. Product one will continue to grow exponentially while Product two will not grow as much in comparison.

Answer: D) phone calls made on a landline

More and more people are using cellphones, because of the convenience of having your phone with you at all times. From an economical standpoint, it doesn't make sense to pay for both a cell phone and a landline (especially if your budget is thin). So many people have decided to drop having a landline all together. The less people using a landline produces a negative downward trend, which is why we have negative linear correlation.

Hi,  

a line is define by  the following equation :    y = ax+b

where  a  is the slope, and  b the value for x = 0

so you have :        a*3 +b = 3   for the first point

                              a*(-5) +b = 4  for second point  

  so you have a system :      3a+b =3

                                              -5a+b = 4

so :       3a+b -(-5a) -b = 3-4

             3a+5a +b-b = -1

             8a = -1

                a = -1/8

then a = -1/8   so , in remplacing a  by it's  value  in one equation ,   b  is :             3(-1/8) +b = 3

 -3/8 +b = 3

           b = 3 +3/8

           b =  24/8 +3/8

          b =  27/8

let's check :     3 (-1/8) + 27/8 =  -3/8 +27/8 = 24/8 = 3

first point is correct  

                         -5( -1/8) + 27/8 =  5/8 +27/8 =  32/8 = 4

second point is correct  

line  is  y = -1/8X +27/8

Answer:

Approximately 18.0.

Step-by-step explanation:

To find x, we can use the Law of Cosines.

The Law of Cosines is the following:

[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]

Now that the c is the side we're trying to find. Thus, the c is x. Also, Angle C is the angle opposite to c (or x). a and b are the two sides next to Angle C.

Plug in x for c, 16 for a, 30 for b, and 30 for Angle C:

[tex]x^2=(16)^2+(30)^2-2(16)(30)\cos(30)\\x^2=1156-960\cos(30)\\x=\sqrt{1156-960\cos(30)} \\x\approx18.0171[/tex]

Answer:

The opposite of integer 4 units away from -6 is 10.

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

Now consider a number line.

The number that is 4 units away from -6 is -10.

So, the number is -10.

The opposite of -10 will be:

- (-10) = 10

Thus, the opposite of integer 4 units away from -6 is 10.

Answer: Hi!

To make an expression that represents ten and a number being divided (hence, quotient) we will use the variable x for the unknown number:

Answer:

B

Step-by-step explanation:

∠ c  = 90° ( angle in a semicircle ), thus

d = 180° - (16 + 90)° = 180° - 106° = 74° ( angles in a Δ )

If one angle is 16° then the measure of angle d is 76°.

An angle is the figure formed by two rays called the sides of the angle, sharing a common point called the vertex of the angle.

We know that each angle of a rectangle and square is equal to 90°. When we observe the given figure then we can see that angles are formed in a rectangle and a,b,c,d,14 and 16 all are in rectangle, so in this way, 14°+d=90°.

d=90-14

d=76°

Hence if one angle is 16° then the measure of angle d is 76°.

Answer:

a) 16.82 mg

b) 24 days

Step-by-step explanation:

Formula for exponential growth is given as:

[tex]A=A_0b^{\frac{t}{c}}[/tex]

Where A is the final population

[tex]A_0[/tex] is the initial population

b is the growth factor

c is the time taken for the growth 'b'

t is the amount of time

Here, We are given the following:

[tex]A_0[/tex] = 5 mg

b = 2 (Given because it doubles)

c = 4 days

a) A = ?

Using the formula:

[tex]A=5 \times 2^{\frac{7}{4}}\\\Rightarrow A=5 \times 2^{1.75} \\\Rightarrow A = \bold{16.82\ mg}[/tex]

b) Given

A = 320 mg

t = ?

Using the above formula again:

[tex]320 = 5 \times 2^{\frac{t}{4}}\\\Rightarrow \dfrac{320} 5= 2^{\frac{t}{4}}\\\Rightarrow 2^{\frac{t}{4}} = 64\\\Rightarrow 2^{\frac{t}{4}} = 2^6\\\Rightarrow \dfrac{t}{4} = 6\\\Rightarrow t = 6 \times 4\\\Rightarrow \bold{t = 24\ days}[/tex]

Hey there!

I see you have to right idea, the first step is to write the equation: 6x-15+2x-2+4x-7=180. We can simplify this to 12x-24=180

Solving for x, we get that x=17.

Let me know if this helps :)

The value of x is 17.

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180, regardless of whether it is acute, obtuse, or right.

Given:

<S = (6x – 15)°, <T = (2x − 2)°, and <U = (4x – 7).

Now, Using Angle Sum Property

<S+ <T + <U= 180

6x - 15 + 2x -2 + 4x - 7= 180

12x - 24= 180

12x = 204

x= 204/12

x= 17

Hence, the value of x is 17.

First you would square root the value 12100 to get one of the length of the square.

[tex]\sqrt{121000}[/tex]=110m

A square has four sides so,

110*4=440m

Answer:

440m

Step-by-step explanation:

Formula of a square's field : a square

So, area is 12,100. Then, let's take this value into the square root.

Now, we found the one edge of this square which is 110m

For finding perimeter, a square has a 4 edge. So, we multiple 110 x 4 = 440m.

Let's assume that total employees are x .

Three - fifths of x is female employees .

→ Female employees = 3x/5 .

Then male employees will be :-

→ Male employees = x - 3x/5

So male employees are 2x/5 .

→ Employees under 18 = x/4

→ Female under 18 = one - third of total female employees.

→ Female under 18 = 3x/5 (1/3)

So Female employees under 18 are x/5 .

→ Now male under 18 = x/4 - x/5

Now male above 18 are = 2x/5- x/20

Ratio of Male above 18 : Male below 18

→ 7x/20 : x/20

→ 7 : 1

So the ratio is 7 : 1 .

(12,-6)

Step-by-step explanation:

Answer:

(12,-6)

Step-by-step explanation:

When dilating points, you multiply both coordinates (x and y) by the scale factor.

The point we are given is: (4,-2) and the scale factor is 3.

Multiply each coordinate by the scale factor of 3.

X-coordinate: 4

     4* 3= 12

New X-coordinate: 12

Y-coordinate : -2

    -2 * 3= -6

New Y-coordinate: -6

Our new x-coordinate is 12 and y-coordinate is -6. Therefore, our point is (12,-6). So, the image of point (4,-2) after a dilation of 3 is (12, -6).

Step-by-step explanation:

Let be a second-order polynomial (quadratic function) is standard form and equalized to zero:

[tex]a\cdot x^{2}+b\cdot x + c = 0[/tex]

Its roots can be determined by the Quadratic Formula in terms of its polynomial coefficients, which states that:

[tex]x_{1,2} = \frac{-b\pm\sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]

Given that [tex]a = 1[/tex], [tex]b = 6[/tex] and [tex]c = 10[/tex], the roots of the polynomial are, respectively:

[tex]x_{1,2} = \frac{-6\pm \sqrt{6^{2}-4\cdot (1)\cdot (10)}}{2\cdot (1)}[/tex]

[tex]x_{1,2} = -3\pm i[/tex]
