The weight of an elephant is 100 times the weight of a cat. If the elephant weighs 14,000 pounds, how many pounds does the cat w
klasskru [66]

Answer:

14 lb

Step-by-step explanation:

10^3 = 1000

14,000 lb/1000 = 14 lb

Since the weight of the elephant is 1000 times the weight of the cat, then the weight of the cat is one-thousandth of the weight of the elephant. To find one-thousandth of a number, divide the number by 1000. 14,000 lb divided by 1000 is 14 lb.

P.S. I feel much better for the cat.

A formula for the relationship between weight and blood pressure in children is given by the formula below where P(x) is measure
photoshop1234 [79]

Answer:

The rate of change of blood pressure at the 50-pound weight level is 0.26

The rate of change of blood pressure at the 80-pound weight level is 0.16

Step-by-step explanation:

We have, P(x) = 12.9(9 + ln x)

We need to compute the rate of change of blood pressure P(x) so, we will differentiate the function P(x) with respect to x.

P(x) = 12.9(9 + ln x)

P(x) = 116.1 + 12.9ln x

Differentiating with repect to x:

\frac{d(P(x))}{dx} = 0 + 12.9 (\frac{1}{x})

\frac{d(P(x))}{dx} = 12.9 (\frac{1}{x})

The differential of ln x is \frac{1}{x} and the differential of constant terms is 0.

The rate of change of blood pressure at the 50-pound weight level can be calculate by substituting 50 in place of x, so

\frac{d(P(x))}{dx} = 12.9 (\frac{1}{x})

          = 12.9 * (1/50)

          = 0.258

\frac{d(P(x))}{dx} = 0.26

Similarly, The rate of change of blood pressure at the 80-pound weight level can be calculate by substituting 80 in place of x, so

\frac{d(P(x))}{dx} = 12.9 (\frac{1}{x})

          = 12.9 * (1/80)

          = 0.16125

\frac{d(P(x))}{dx} = 0.16

Landon is standing in a hole that is 5.1 ft deep. He throws a rock, and it goes up into the air, out of the hole, and then lands
kati45 [8]
This describes a parabolic path that starts at x=0 on a value of y = -5.1.  That's when the rock is below ground in the hole.  To find the answer we need to know the second x axis crossing.  The first is when it is rising and reaches ground level, the second is after it peaks and falls back to the ground and lands. Using the quadratic formula I get the two zeros of this function to be about
x= 15.29, and 66.71.  The rock then lands 66.71 feet from him horizontally.
