4 week it drop 3 feet what is the unit rate

1 answer:

3 0

In 4 weeks, it dropped 3 feet in total.
The unit rate of this is 3 feet / 4 weeks
If we simplify this into days, this will be the solutions
=> 4 weeks has (4 * 7) 28 days in total, so we need to divide 3 feet by 28 days to get the simplified unit rate.
=> 3 feet / 28 days
=> .107 feet / day.
So the water drops .107 feet per day and in 4 weeks the total of 3 feet.

The oxygen consumption (in milliliter per pound per minute) for a person walking at x mph is approximated by the function f(x)=\

Oliga [24]

Answer: Speed = 5.6 mph

Oxygen consumption = 71.6 mL/lb/min

Step-by-step explanation: For the oxygen consumption to be the same, functions must be equal:

f(x) = g(x)

$\frac{5}{3}.x^{2} + \frac{5}{3}.x+10=11x+10$

Resolving:

$\frac{5}{3}.x^{2} + \frac{5}{3}.x - 11x =0$

$\frac{5}{3}x^{2} + \frac{5}{3}x - \frac{33x}{3}=0$

$\frac{5}{3}x^{2} - \frac{28x}{3}=0$

$\frac{x}{3}(5x - 28)=0$

$\frac{x}{3} = 0$

x=0

5x - 28 = 0

$x = \frac{28}{5}$

x = 5.6

The speed when the oxygen consuption is the same is 5.6 mph.

For the level of oxygen consumption:

f(5.6) = g(5.6)

g(5.6) = 11*5.6 + 10

g(5.6) = 71.6

The level of oxygen consumption is 71.6 mL/lb/min

Why does a conjugate pair make a difference of 2 squares?

allsm [11]

Answer:

where one perfect square is subtracted from another, is called a difference of two squares. It arises when (a − b) and (a + b) are multiplied together. This is one example of what is called a special product.

Step-by-step explanation:

Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
