What is the domain of the function shown on the graph?
Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for all exponential functions, including this one.

Find the radius of a circle that has a circumference of 16
The formula for the circumference of a circle is C = 2.
where r is the radius and C is the circumference. The
TE
equation solved for r is r =
27
O r=4
O r= 8
O r= 12
O r= 16
Answer:
The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .

Ecuacion de la recta que pasa por el punto donde se cortan las rectas X+4Y=0 y X-3Y-7=0 y que tiene como pendiente -6
Answer:
La ecuación de la recta es [tex]y = -6\cdot x +23[/tex].
Step-by-step explanation:
Para construir la ecuación de la recta podemos utilizar un punto contenido en la recta y su pendiente. En primer punto, hallamos el punto con la resolución del siguiente sistema de ecuaciones lineales:
[tex]x+4\cdot y = 0[/tex] (1)
[tex]x-3\cdot y = 7[/tex] (2)
La solución del sistema de ecuaciones es [tex](x,y) = (4,-1)[/tex].
Por Geometría Analítica, sabemos que la Ecuación de la Recta en su forma explícita es:
[tex]y = m\cdot x + b[/tex] (3)
Donde:
[tex]x[/tex] - Variable independiente.
[tex]y[/tex] - Variable dependiente.
[tex]m[/tex] - Pendiente.
[tex]b[/tex] - Intercepto.
Si sabemos que [tex](x,y) = (4,-1)[/tex] y [tex]m = -6[/tex], entonces el intercepto de la recta es:
[tex]b = y-m\cdot x[/tex]
[tex]b = 23[/tex]
Ahora, la ecuación de la recta es [tex]y = -6\cdot x +23[/tex].
(5y+1)²-4(y-1)² how to solve it
Answer:
[tex](5y + 1)^{2} - (2(y - 1))^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y - 1 ).
[tex](5y + 1) ^{2} - (2(y - 1)) ^{2} [/tex]
2) Use multiplication Distributive Property: (xy)^a = x^a y^a.
[tex](5y + 1)^{2} - {2}^{2} (y - 1 {)}^{2} [/tex]
3) Simplify 2² to 4.
[tex](5y + 1 {)}^{2} - 4(y - 1 {)}^{2} [/tex]
4) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y-1).
[tex](5y + 1 {)}^{2} - (2(y - 1))^{2} [/tex]
Therefor, the answer is ( 5y + 1 )² - (2( y - 1 ))².

b:40
c:45
d:50
e:60
Answer:
B
Step-by-step explanation:
if you multiply m by 2 you get 260we now want to subtract this from 360 to get 100 then we divide that by 2 to get angle n∠BEF= 50°.
We know angle k∠EBF= 90° so we now end up with adding angle ∠BEF with ∠EBF to get 140 to get angle x we subtract 140 from 180 to get 40. x=40°. so B is the correct answer

Hello There!
The problem states that the angles are complementary angles
Complementary angles are angles that have measures that add up to equal 90
So given one of the angles we can find the missing angle by subtracting the known angle from 90
90 - 81 = 9
so we can conclude that the measure of angle 2 is 9

Tony and Edwin each built a rectangular garden. Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden. If the perimeter of Edwin's garden is 36 feet, what is the perimeter of Tony's garden?
Answer:
54 feet
Step-by-step explanation:
Perimeter of a rectangle = 2 × (length + breadth)
The perimeter of Edwin's garden is 36 feet :
36 = 2 x (length + breadth)
divide both sides by 2 to determine the sum of the length and breadth of Edwin's garden
36/2 = (length + breadth)
18 = (length + breadth)
Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden
The dimensions of Tony's garden is :
(4 + l) + (5 + w) = 9 + l + w
Where :
l = length
w = width
The sum of the length and breadth of Tony's garden would be 9 feet more than that of Edwin
Sum of Edwin's garden = 9 + 18 = 27
Perimeter of Edwin's garden = 27 feet x 2 = 54 feet
