What is the domain of the following relation? {(-3, -8), (-2, 9), (1, -1), (5, 3)}
Answer:
Domain:
{−3,−2,1,5}
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}.

What is 767,000 expresses in scientific notation
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].

Step-by-step explanation:
In 2005, the population of a state was 31,006,000. If the population grows at 1.2% per year, approximately how
many years (from 2005) will it take the population to reach 40,000,000? (Assuming it grows at the same rate)
use the continuous growth function:
A=pen
150 years
249 years
21 years
26 years
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.
Exponential growth of the poulation: Exponential growth for the population growth is given by the expression,
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,
Initial population = 31006000Growth rate = 1.2%Final population = 40000000To 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.

The shorter leg of a right triangle is 2 feet shorter than the longer leg. The hypotenuse is 10 feet. How long is each leg?
a=shorter leg
b=longer leg
c=hypotenuse
a=b-14
c^2=a^2+b^2
26^2=(b-14)^2+b^2
676=b^2-2*b*14+14^2+b^2
676=2b^2-28b+196
676-196=2(b^2-14b)
480=2(b^2-14b) Divide with 2
240=b^2-14b
b^2-14b=240
b^2-14b+7^2=240+7^2
Becouse: (b-7)^2=b^2-14b+7^2
(b-7)^2=240+49
(b-7)^2=289
b-7=sqroot(289)
You have two solutions:
b-7=17 and
b-7=-17
Becouse sqroot(289)=+/- 17
First solution: b-7=17
b=17+7=24
Second solution:
b-7=-17
b=17+7=-10
leg of triangle can not be negative number so:
b=24
a=b-14=24-14=10
a=10 b=24
c=sqroot(a^2+b^2)
c=sqroot(10^2+24^2)
c=sqroot(100+576)
c=sqroot(676)
c=26

Cuánto tarda un vehículo en recorrer 26 km con una velocidad constante de100km/h
Answer:
Un vehículo tardará 15 minutos y 36 segundos en recorrer 26 km con una velocidad constante de 100km/h.
Step-by-step explanation:
Para determinar cuánto tarda un vehículo en recorrer 26 km con una velocidad constante de 100km/h se deben realizar los siguientes cálculos:
(26/100) x 60 = X
0.26 x 60 = X
15.6 = X
1 = 60
0.6 = X
0.6 x 60 = X
36 = X
Por lo tanto, un vehículo tardará 15 minutos y 36 segundos en recorrer 26 km con una velocidad constante de 100km/h.

Given ABCD as marked, what additional information would help you to prove that ABCD is a square? Pls I rlly need help
9514 1404 393
Answer:
a. AC ≅ BD
Step-by-step explanation:
All four sides are marked as being the same length. This means the figure is a parallelogram and a rhombus.
Diagonals bisect each other in any parallelogram. They are perpendicular, and bisect the corner angles, in any rhombus. Choices b, c, and d add no new information.
In order to show the figure is a square, you must show this rhombus is a rectangle: the diagonals must be the same length. That is you must show ...
AC ≅ BD
_____
Additional comment
You may be given problems with coordinates, and asked to show the figure is a parallelogram, rectangle, rhombus, or square. Often, the problem is given with the intent that you use slope and length formulas on the given points to prove opposite sides are parallel and the same length. IMO, these problems are much simpler if you show the appropriate relation exists between the midpoints, slopes, and lengths of the diagonals.
Point P divides the directed segment from A to B in the ratio 9 to 2. The coordinates of point A are
(-4,-2) and the coordinates of point P are (2, 1). Find the coordinates of point B. Round your answer to
the nearest tenth if necessary.
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]
