The two roots [tex]a +\sqrt{b}[/tex] and [tex]a -\sqrt{b}[/tex] are called conjugate radicals

The conjugate of a radical is the value which when multiplied with the radical expression clears the radical. Conjugates have the same numbers but the opposite sign in the middle.

The given roots are

[tex]a +\sqrt{b}[/tex] and [tex]a -\sqrt{b}[/tex]

They have the same numbers but opposite signs in the middle.

Considering the volume of the rectangular prism, you will need 2240 bags will be needed for the patio.

The volume of a rectangular prism of length l, width w and height h is given by:

V = lwh.

In this problem, the dimensions are:

l = 14 ft, w = 12 ft, h = 8 ft.

Hence the volume is:

V = 14 x 12 x 8 = 1344 ft³

Each bag yields 0.6 ft³, hence the number of bags is:

n = 1344/0.6 = 2240 bags.

Answer:

134217728

Step-by-step explanation:

The geometric sequence formula is:

[tex]\displaystyle{a_n = a_1r^{n-1}}[/tex]

We know that [tex]\displaystyle{a_1=8}[/tex] and [tex]\displaystyle{r=2}[/tex], we also want to find the 25th term, substitute n = 25:

[tex]\displaystyle{a_{25}=8\cdot 2^{25-1}}\\\\\displaystyle{a_{25}=8\cdot 2^{24}}\\\\\displaystyle{a_{25}=134217728}[/tex]

Therefore, the 25th term of sequence is 134217728

By solving a system of equations we will see that the two-digit number is 84.

"The tens digit of a number is twice the ones digit"

"The sum of the digits is 12".

A two-digit number can be written as:

a*10 + b

Where a is the tens digit and b is the ones digit.

The word problem can then be written as:

a = 2*b

a + b = 12

So we have a system of equations.

To find the number we need to solve these, if we replace the first equation into the second one:

a + b = 12

(2b) + b = 12

3b = 12

b = 12/3 = 4

Then:

a = 2b = 2*4 = 8

So the two-digit number is 84.

Answer:

D

Step-by-step explanation:

Let's start by crossing everything out!

12/3 can be crossed out to 4.

a^3/a^2 can be crossed out to a.

b^6/b^4 can be crossed out into b^2.

c^5/c^5 is just 1.

So which the results we got, we can multiply them, so that it is 4ab^2.

4ab^2 is our final answer!

Answer:

z=2

Step-by-step explanation:

We are given that a line has a slope of 3.

The line passes through the points (-10, z) and (-8, 8)

We want to find the value of z.

To do that, we can calculate the slope.

The slope can be calculated using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

Even though we already have 2 points, let's label their values to avoid any confusion.

[tex]x_1=-10\\y_1=z\\x_2=-8\\y_2=8[/tex]

Now substitute those values into the formula, and set it equal to 3. Remember that the formula uses subtraction.

[tex]\frac{8-z}{-8--10}[/tex] = 3

We can simplify this first.

[tex]\frac{8-z}{-8+10}[/tex] = 3

[tex]\frac{8-z}{2}[/tex] = 3

We can multiply both sides by 2 to clear the fraction and make it easier to calculate.

2([tex]\frac{8-z}{2}[/tex])  = 2(3)

Multiply.

8 - z = 6

Subtract 8 from both sides

-z = - 2

Multiply both sides by -1.

-1(-z) = -1(-2)

Multiply.

z = 2

Using it's concept, it is found that the period of the function is of 20 units.

The period of a function is given by the distance between it's repetitions.

A. The exponential growth function that models the data is: [tex]A(t) = 5.89{0.0106t}[/tex]

B. Using the function, the population will be 11 million by 2059.

The function is given by:

[tex]A(t) = A(0)e^{kt}[/tex]

In which:

Item a:

We have that:

A(0) = 5.89, A(50) = 10.

We use this to find k, hence:

[tex]A(t) = A(0)e^{kt}[/tex]

[tex]10 = 5.89e^{50k}[/tex]

[tex]e^{50k} = \frac{10}{5.89}[/tex]

[tex]\ln{e^{50k}} = \ln{\frac{10}{5.89}}[/tex]

[tex]50k = \ln{\frac{10}{5.89}}[/tex]

[tex]k = \frac{\ln{\frac{10}{5.89}}}{50}[/tex]

k = 0.0106.

Hence the equation is:

[tex]A(t) = 5.89{0.0106t}[/tex]

Item b:

We have to solve for t when A(t) = 11, hence:

[tex]A(t) = A(0)e^{kt}[/tex]

[tex]11 = 5.89e^{0.0106t}[/tex]

[tex]e^{0.0106t} = \frac{11}{5.89}[/tex]

[tex]\ln{e^{0.0106t}} = \ln{\frac{11}{5.89}}[/tex]

[tex]0.0106t = \ln{\frac{11}{5.89}}[/tex]

[tex]t = \frac{\ln{\frac{11}{5.89}}}{0.0106}[/tex]

t = 58.9

Rounding up, the population will be of 11 million in 2059.

Step-by-step explanation:

z² + 5z + 6 can be factored into (z+3)(z+2)

zx + 2x − 8z-16 can be factored into (x-8)(z+2)

the LCM would be (z+2)(z+3)(x-8)

if you were to multiply the two expressions together, you would multiply (z+2)^2, which is not necessary for LCM, which is why you factor them first

Answer: Sorry If I'm wrong but if you are asking for the missing angle on the bottom, I think it is 30 degrees.

Step-by-step explanation: All the angles in a triangle add up to 180 degrees. we already know that one is 50 degrees. The 2nd angle is a bit wider than a 90 degree angle, and the third angle is 30 degrees, so 50 degrees + 100 degrees + 30 degrees add up to 180. So, I think your answer would be 30 degrees.

Answer:

x = 25

Step-by-step explanation:

I added a drawing down below to guide you through!

First, we should remember, that if a line crosses two parallel lines, then the adjacent angles will have the same value. Since Line D and Line E are parallel and line BC is crossing it, angles ABC and 105 will be the same.

Now that we know one of the missing angles, we can find x easily!

All angles in a triangle add up to 180, so in this case, the equation will be: 50 + 105 + x = 180.

155 + x = 180

x = 25.

So x will equal to 25 degrees!

Using proportions, it is found that the new minimum price you need to set for the remaining watercolor paintings in order to pay for the materials is of $2.89.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

To pay for the materials, you need to sell 18 paintings at $2.25 each, hence the total is:

T = 18 x 2.25 = $40.5.

If you lose four paintings, you will sell 14, and still need to make $40.5, hence the price will be of:

P = $40.5/14 = $2.89.
