Translate into an algebraic expression: If I travel d miles in h hrs downstream on a river with a current of c mph, what would m
xenn [34]

Answer:

The speed is still water is v = \frac{d}{h} - c.

Step-by-step explanation:

Dimentionally speaking, speed is distance divided by time. Since, the person is travelling downstream, absolute speed is equal to the sum of current speed and speed of the person regarding current. Both components are constant. That is:

c + v = \frac{d}{h}

Where:

c - Current speed, measured in miles per hour.

v - Speed of the person regarding current, measured in miles per hour.

d - Distance travelled downstream, measured in miles.

h - Time spent on travelling, measured in hours.

Speed in still water occurs when current speed is zero. Then, such variable is obtained after subtracting current speed on both sides of the expression. Hence:

v = \frac{d}{h} - c

The speed is still water is v = \frac{d}{h} - c.

Please some help for question 1
o-na [289]

Answer:

f (3) is equal to 31

Step-by-step explanation:

f (3) means that x is equal to 3 [hence f (x) ---> f (3)]

Plugin 3 into all the x values to solve:

4(3)^2 - 2(3) + 1

4(9) - 6 + 1

36 - 6 + 1

30 + 1

31

f (3) is equal to 31
