hichkok12 [17]2 years ago
3 0

EXPLANATION: Simply substitute the value of 3 given. In other words, f(3) is the function of f(x), however, in this case, x is 3

f(3)=3(3)−4

Distribute 3 through the parenthesis

f(3)=9−4

Simplifyf(3)=5

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

What is the translation of EFG with vertices E(3, 2), F(2, 5), G(−1, 2) by vector − − 1, 4 ?
sesenic [268]

Answer:

The correct answer is (4 , 6); (3 , 9); (0 , 6)

Step-by-step explanation:

In translation by a vector, we simply add or subtract the coordinates of a point with the vector to get the translated coordinates of the point.

Here the vector is 1 , 4.

Thus, the point E(3 , 2) would translate to ( 3+1 , 2+4) = ( 4 , 6 ).

The point F(2 , 5) would translate to ( 2+1 , 5+4) = ( 3 , 9 ).

The point G(-1 , 2) would translate to ( -1+1 , 2+4) = ( 0 , 6 ).
