what is the rate of change of y with respect to x for this function​

Answers

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.

Five angles of a hexagon are each 115°. Calculate the size of the sixth angle.

Answers

A hexagon adds up to 720,
So we would do
115 x 5 = 575
So you would do
720 - 575 which is 145.
So the sixth angle is 145 degrees.

Answers

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 > 5/4

That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

Answers

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

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?

Answers

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

Answers

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]
