LOTS OF POINTS + BRAINLIEST

Mathematics
1 answer:
Gekata [30.6K]2 years ago
5 0

Answer:

The list od prime number is a quadratic sequence, each time going up by n + 2. for example, 1, 4, 9, 16, 25. they are going up by 3, then + 2 and add 2 every step. The sequence is always going up by an odd number. a negative number take away a negative number always gives you a positive number, likewise, adding does too. Therefore, you can not get both of them to fit into the sequence of increasing odd numbers.

Every 125 pages that Raul reads during his summer reading challenge, he will collect 5 book points to use at his local library.
monitta

Answer:

The answer is "\frac{1}{25}"

Step-by-step explanation:

They might claim that perhaps the ratio to Raul would've been:\frac{y}{x} = \frac{5}{125} = \frac{1}{25} per each 125(x) page, which he reviewed throughout a summer competition.

Raul's cost per unit for each paragraph reads is \frac{1}{25} page points, that's why the model a link with the same unit rate. please find the graph in the attached file.

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
