To calculate a patient's heart rate, the doctor must take into account a segment of time, such as a minute, and count the number of times the heart beats in that segment.

Heart rate is a term that refers to the number of heart contractions or beats per unit of time.

Heart rate is usually measured at various points, but most commonly it is measured at the wrist, neck, or chest.

According to the above, the most common way for the doctor to establish the patient's heart rate is to count the heart beats in a segment of time such as one minute.

Answer:

Diverge

Step-by-step explanation:

Each successive term is larger than the previous one, so the series will diverge.

The given series can be condensed to

[tex]\displaystyle \frac14 + \frac13 + \frac49 + \frac{16}{27} + \frac{64}{81} + \cdots = \frac14 \left(1 + \frac43 + \frac{4^2}{3^2} + \frac{4^3}{3^3} + \cdots\right) = \frac14 \sum_{n=0}^\infty \left(\frac43\right)^n[/tex]

which is a geometric series with ratio 4/3. Since this ratio is larger than 1, the sequence of partial sums of the series diverges, so the infinite series also diverges.

We can also just the n-th term test:

[tex]\displaystyle \lim_{n\to\infty} \frac14 \left(\frac43\right)^n = \frac14 \lim_{n\to\infty} \frac{4^n}{3^n} = \infty[/tex]

since 4ⁿ > 3ⁿ for all n > 0.

Answer:

Figure JK is shown in the drawing.

Step-by-step explanation:

A' = (-6, 2), B' = (-3/2, 4), C' = (9/2, 3),  D' = (3, -2) and E' = (-3, -1). The new figure is similar to the original figure

An equation is an expression that shows the relationship between two or more variables and numbers.

A horizontal stretch by a factor of k uses the rule: (x,y) → (kx, y). Pentagon ABCDE is stretched horizontally by a factor of 3/2, hence:

A' = (-6, 2), B' = (-3/2, 4), C' = (9/2, 3),  D' = (3, -2) and E' = (-3, -1)

Step-by-step explanation:

The angle 11π/12 radian after converting it to degree it become 165 degree.

The measurement between the two lines is called an "Angle" when the two lines or rays converge at a common location.

We have given:

An angle 11π/12

Let's denote it with β

[tex]\rm \beta = \dfrac{11\pi}{12}[/tex]

To convert it to degree, replace π with 180°, we get:

[tex]\rm \beta = \dfrac{11\times180}{12}[/tex]

β = 165°

Thus, the angle 11π/12 radian after converting it to degree it become 165 degree.

Answer:

Step-by-step explanation:

The quantity of tickets sold is presumed to be a linear function of the price. The revenue from sales will be the product of the number sold and their price.

__

The quantity sold is reduced by 10 when the price goes up 1, so the slope of the quantity curve is -10/1 = -10. The given point on the quantity curve is (p, q) = (4, 200). Using these values in the point-slope equation of a line, we find ...

  q -200 = -10(p -4)

  q = -10(p -4) +200 . . . . . add 200

Then the revenue is ...

  r(p) = pq

  r(p) = p(-10(p -4) +200) = p(-10p +240)

  r(p) = -10p(p -24) . . . . factored form

This equation describes a parabola with zeros at p=0 and p=24. The peak value of the revenue is on the axis of symmetry, halfway between the zeros. That is, the price p=12 will maximize revenue. At that price, the revenue is ...

  r(12) = -10(12)(12 -24) = 10(144) = 1440

The maximum revenue is $1440 at a ticket price of $12.00.

The two angles are 45 degrees.

Step-by-step explanation:

You are just halfing the 90 degree angle, so all you have to do is divide 90 by two, and you have 45.

Answer:

The correct answers are Quadratic and More.

Step-by-step explanation:

I got it right on the Edmentum test.

The graph is a quadratic function, and the equation of the function is C(x) = (x + 4)(x - 3)

From the graph the x-intercepts are:

x = -4 and x = 3

Rewrite as:

x + 4 = 0 and x - 3 = 0

Evaluate the product of both equations

(x + 4) * (x - 3) = 0* 0

This gives

(x + 4)(x - 3) = 0

Express as a function

C(x) = (x + 4)(x - 3)

Hence, the equation of the function is C(x) = (x + 4)(x - 3)

The true statements are:

From the complete question, we have the dimensions of the parking lot to be: 78 meters by 19 meters

Also, the dimension of the aisle is: 8 meters by 78 meters

The total parking area is the difference between the parking lot area and the aisle area

This gives

Parking Area = 78 * 19 - 8 * 78

Parking Area = 858

The total area available for cars to park is 858 square meters

The number of parking lot is the quotient of the total parking area and the area of each compact

So, we have:

n = 858/12.5

n = 68.64

Remove the decimal

n = 68

Hence, the number of parking space is 68

The number of parking lot is the quotient of the total parking area and the area of each non-compact space

So, we have:

n = 858/(5.5 * 3)

n = 52

Hence, the number of parking space is 52
