what is the rate of change of y with respect to x for this function
Answer:I got -0.2
Step-by-step explanation:
The rate of change of y with respect to x for this function should be considered to be the -0.2.
Calculation of the rate of change:Since
x = -3
y = 3.6
[tex]x_1[/tex] = 5
[tex]y_1[/tex] = 2
So here the rate of change be
[tex]= (y_1 - y) \div (x_1 - x)\\\\[/tex]
= (2-3.6) ÷ (5 + 3)
= -1.6 ÷ 8
= -0.2
Hence, The rate of change of y with respect to x for this function should be considered to be the -0.2.

triangle ABC is shown in the diagram. The links of the sides are in terms of the variable n, where n >4. complete the inquality
9514 1404 393
Answer:
m∠B < m∠A < m∠C
Step-by-step explanation:
We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.
For n = 4, the side lengths are ...
a = 2(4) = 8
b = (4) +3 = 7
c = 3(4) -2 = 10
The longest side is opposite the largest angle, so the ordering of angles is ...
m∠B < m∠A < m∠C
_____
The triangle inequality requires all of these inequalities be true:
a+b > c ⇒ 3n+3 > 3n-2 . . . always trueb+c > a ⇒ 4n+1 > 2n ⇒ n > -1/2c+a > b ⇒ 5n-2 > n+3 ⇒ n > 5/4That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

La casa de Mauricio está construida en un terreno de forma rectangular, el cual mide el doble de largo que de ancho. Mauricio asegura que el área del terreno es de 242 metros cuadrados. ¿cuál es la expresión algebraica correspondiente al área del terreno?
Answer:
x^2 = 121
Step-by-step explanation:
Sea el ancho del terreno x metros
Dado que la longitud es el doble del ancho, entonces la longitud será 2 * x = 2x
Matemáticamente, el área de un rectángulo es;
Anchura longitud Por lo tanto, tenemos
x * 2x = 242 metros cuadrados
Así; 2x ^ 2 = 242
x ^ 2 = 242/2
x ^ 2 = 121
Help me please I need help with this
Answer:
A
You plug in the same x value for each and see the answer. So 2(5)*10^4= 100000. And for the other we do 4(5)*10^2 which is 200. Since is says that 2x10^4 is 50 times as great as 4x10^2, we know that a is right because 200 * 50 = 100000.

Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute. A If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?
Answer:
The answer is below
Step-by-step explanation:
Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute.
a) If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?
b) How long did it take Max to complete 4 laps backstroke?
c) It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke. Write the equation that describes this fact.
d) What is the length of the swimming pool?
Solution:
a) Speed is the ratio of distance to time, it is given as:
speed = distance/time
1 lap = d meters, hence:
4 laps = 4d meters
Max swims the breaststroke at 50 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_1[/tex] minutes hence:
50 = 4d/[tex]t_1[/tex]
[tex]t_1\\[/tex] = 4d/50
[tex]t_1[/tex] = 2d/25 minutes
b) 1 lap = d meters, hence:
4 laps = 4d meters
Max swims the backstroke at 25 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_2[/tex] minutes hence:
25 = 4d/[tex]t_2[/tex]
[tex]t_2[/tex] = 4d/25 minutes
c) Since It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke
[tex]t_2=t_1+2[/tex]
c)
[tex]t_2=t_1+2[/tex]
[tex]\frac{4d}{25}= \frac{2d}{25}+2\\\\multiply\ through\ by\ 25:\\\\4d = 2d +50\\\\4d-2d=50\\\\2d=50\\\\d=25\ meters[/tex]
The pool is 25 meters long

Answer:
Area = 76[tex]m^{2}[/tex]
Step-by-step explanation:
you can cut into two rectangles
first one:
top and bottom sides = 4m
two sides = 9m
Area = b*h = 9m * 4m = 36 [tex]m^{2}[/tex]
second one
top and bottom sides = 8m
two sides = 14m - 9m = 5m
Area = b*h = 8m * 5m = 40[tex]m^{2}[/tex]
Now add both rectangle areas for the total shaded Area = 36 + 40 = 76[tex]m^{2}[/tex]
