Answer:

[tex]B =(3.3,1.7)[/tex]

Step-by-step explanation:

Given

[tex]A(x_1,y_1) = (-4,-2)[/tex]

[tex]P(x,y) = (2,1)[/tex]

[tex]m : n = 9 : 2[/tex]

Required

The coordinates of [tex]B(x_2,y_2)[/tex]

The line segment from ratio is calculated as:

[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]

Substitute: A, P, m and n

[tex](2,1) = (\frac{9 * x_2 + 2*-4}{9+2},\frac{9*y_2 +2 *-2}{9+2})[/tex]

[tex](2,1) = (\frac{9x_2 -8}{11},\frac{9y_2 -4}{11})[/tex]

Multiply through by 11

[tex](22,11) = (9x_2 -8,9y_2 -4)[/tex]

By comparison:

[tex]9x_2 - 8 = 22[/tex]

[tex]9y_2 - 4 = 11[/tex]

So, we have:

[tex]9x_2 - 8 = 22[/tex]

[tex]9x_2 = 22 +8[/tex]

[tex]9x_2 = 30[/tex]

Solve for x2

[tex]x_2 = 30/9[/tex]

[tex]x_2 = 3.3[/tex]

[tex]9y_2 - 4 = 11[/tex]

[tex]9y_2 = 11+4[/tex]

[tex]9y_2 = 15[/tex]

Solve for y2

[tex]y_2 =15/9[/tex]

[tex]y_2 =1.7[/tex]

So, the coordinates of B is:

[tex]B =(3.3,1.7)[/tex]

Answer:

767,000 in scientific notation is [tex]7.67*10^5[/tex].

Step-by-step explanation:

A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 and multiplied by a power of 10. In this case, if 767,000 were to be written in scientific notation, then you need to move the decimal place of the number until you have a number that meets the requirement above. 7.67 would be the number to use, and you need to multiply that by a power of 10 that makes the product the original number, so the power would be 5. So 767,000 in scientific notation would be [tex]7.67*10^5[/tex].

Hello! answer: 68

Step-by-step explanation:

x = 19 19 × 4 = 76 76 + 36 = 112

19 × 6 = 114 114 - 2 = 112

112 + 112 = 224 360 - 224 = 136 136 ÷ 2 = 68 therefore the answer is 68

Answer:

Below in bold.

Step-by-step explanation:

Part A.

9a^2 - 24a + 16

= (3a - 4)(3a - 4).

Length of each side = 3a - 4 units.

Part B.

25a^2 − 36b^2

= (5a - 6b)(5a + 6b).

The dimensions are 5a-6b and 5a+6b.

The length of each side would be 3a - 4 units. The dimensions are 5a - 6b and 5a + 6b.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

Part A.

The area of a square is [tex]9a^2 - 24a + 16[/tex] square units.

To determine the length of each side of the square by factoring the area expression completely.

[tex]9a^2 - 24a + 16\\\\= (3a - 4)(3a - 4).[/tex]

The Length of each side = 3a - 4 units.

Part B.

The area of a rectangle is [tex]25a^2 - 36b^2[/tex]square units.

To determine the dimensions of the rectangle by factoring the area expression completely.

[tex]25a^2 - 36b^2\\= (5a - 6b)(5a + 6b).[/tex]

The dimensions are 5a - 6b and 5a + 6b.

Answer:

Step-by-step explanation:

      Population of the state will reach 40,000,000 in 21 years from year 2005.

      Option (3) will be the correct option.

          F = I(1 + r)ⁿ

          Here, F = Final population

                    I = Initial population

                    r = Growth rate

                    n = Number of years for population growth

Given in the question,

To find the number of years for population growth, substitute the values,

F = I(1 + r)ⁿ

40000000 = 31006000(1 + 0.012)ⁿ

40000 = 31006(1.012)ⁿ

[tex](1.012)^n=\frac{40000}{31006}[/tex]

[tex]\text{log}(1.012)^n=\text{log}(1.29)[/tex]

nlog(1.012) = log(1.29)

0.00518n = 0.11059

n = [tex]\frac{0.11059}{0.00518}[/tex]

n = 21.34

n ≈ 21 years

     Therefore, population of the state will reach 40,000,000 in 21 years from 2005. Option (3) will be the answer.

Answer:

Step-by-step explanation:

The formula you need for this is

[tex]A(t)=P(1+\frac{r}{n})^{nt[/tex] where

A(t) is the amount after a certain number of years has gone by,

P is the initial deposit,

r is the interest rate in decimal form,

n is the number of compoundings done per year, and

t is the amount of time in years.

For us,

A(t) = 11900

P is 250

r is .048

n is 12 (there are 12 months in a year)

t is our unknown. Filling in:

[tex]11900=250(1+\frac{.048}{12})^{(12)(t)[/tex] which simplifies a bit to

[tex]11900=250(1_.004)^{(12t)[/tex] . Now we'll divide both sides by 250:

[tex]47.6=(1.004)^{12t[/tex] and then take the natural log of both sides to bring that t down out front:

[tex]ln(47.6)=ln(1.004)^{12t[/tex] and then

ln(47.6) = 12t ln(1.004). Now divide both sides by ln(1.004) to isolate the 12t:

967.6383216 = 12t and divide both sides by `12 to get

t = 80.6 months which is 6.7 years

So to find area follow the formula

a=πr^2

a=area

π= pi or 3.14 in this situation

r= radius

So we have only the diameter.

To in Find the radius you can divide the diameter by 2 and get the radius which is

84/2=42

3.14*42^2=

Area: 5538.96 ft^2

2) Circumference:

To find the circumfeence you just multiply the diameter by π or in this case 3.14.

c=πd

c= circumference  

d= diameters

Step-by-step explanation:

The domain of the given relation is {-3, -2, 1, 5} of the following relation {(-3, -8), (-2, 9), (1, -1), (5, 3)}

The domain of a relation refers to the set of all possible input values or x-values in the relation. In the given relation {(-3, -8), (-2, 9), (1, -1), (5, 3)}, the x-values or the first components of each ordered pair represent the domain.

The domain of a relation is the set of all possible input values or x-values for which the relation is defined. It represents the range of values that can be used as inputs to the relation to obtain corresponding outputs. In other words, the domain is the set of values that the independent variable can take in the relation.

Therefore, the domain of the given relation is {-3, -2, 1, 5}.
