stira [4]

Answer:

10mins

Step-by-step explanation:

you can draw a rtd chart for this problem

             rate (m/min)|  time (mins)  | distance (m )

regular: (300/x)  | x  | 300m

fist 1/4 : (300/x) | 75: (300/x)  | 75m

last 3/4:  | (300/x)+15 | 225:(300/x + 15) | 225m

then, make an equation for the times:

x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x

// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop

solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer

Answer:

10x -  \frac{1}{x}  = 3 \\ 10x = 3 +  \frac{1}{x}  \\ 10x =  \frac{3x + 1}{x}  \\ 10x \times x = 3x + 1 \\ 10 {x}^{2}  = 3x + 1 \\ 10 {x}^{2}  - 3x - 1 = 0 \\ 10 {x}^{2}  - 5x + 2x - 1 = 0 \\ 5x(2x - 1) + 1(2x - 1) = 0 \\ (5x + 1)(2x - 1) = 0 \\  \\ 5x + 1 = 0 \\ 5x =  - 1 \\ x =  \frac{ - 1}{5}  \\  \\ 2x - 1 = 0 \\ 2x = 1 \\ x =  \frac{1}{2}

If f(x) = x3, which graph represents g(x) = f(x) + 4?
Jlenok [28]

Answer:

From the attached diagram, it is clear that:

  • Red graph represents the function f(x) = x³
  • Blue graph represents the function g(x) =  x³+4

It is clear from the blue line graph, that when we add 4 units to the output of the parent function, it will be shifted 4 units up.

Step-by-step explanation:

Given the function

  • f(x) = x³

The graph of the function f(x) is attached below.

We know that when we add the number, let say h, to the function output, it means the graph is shifted 'h' units up.

So, when we add 4 units to the graph f(x), it means the graph will be shifted 4 units up.

Therefore, the graph g(x) = f(x)+4 will be result of shifting 4 units up.

The diagram graph of both f(x) and g(x) is attached below.

From the attached diagram, it is clear that:

  • Red graph represents the function f(x) = x³
  • Blue graph represents the function g(x) =  x³+4

It is clear from the blue line graph, that when we add 4 units to the output of the parent function, it will be shifted 4 units up.
