A doctor observes a graph that shows the electrical activity (in volts) of the heart of a patient over a period of time (in seconds). Each spike corresponds to one heart beat. The doctor needs to calculate the heart rate of the patient in beats per minute.
What is the heart rate of this patient?
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.
What is heart rate?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:
No solution
Step-by-step explanation:
As the coefficient of x is the same, and the constant terms are different, the lines will lie parallel to each other and never intersect.
Hence, this system of equations has no solution.

Consider the series [tex]\frac{1}{4} +\frac{1}{3} +\frac{4}{9} +\frac{16}{27} +\frac{64}{81}[/tex]
Does the series converge or diverge?
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.

Which linear inequality is represented by the graph?
Answer:
y≤2/3x+1/5
or the very first one
Step-by-step explanation:
Solve this system of linear equations. Separate
the x- and y-values with a comma.
15x = -42 - 19y
3x = -54 - 19y
15x=-42-19y
15x+19y+42=0-(1)3x=-54-19y
3x+19y+54=0--(2)Subtract both
12x-12=012x=12x=1Put in second
3(1)+19y+54=019y+57=0y=-3So
(x,y)=(1,-3)Answer:
1, -3
Step-by-step explanation:
QuestionSolve the system of linear equations:
15x = -42 - 19y3x = -54 - 19y-------------------------------------------------------------------------------------
SolutionSubtract the equations to eliminate y:
15x = -42 - 19y
- 3x = -54 - 19y
----------------------
12x = 12
⇒ x = 12 ÷ 12
⇒ x = 1
Now substitute the found value of x into one of the equations and solve for y:
⇒ 15x = -42 - 19y
⇒ 15(1) = -42 - 19y
⇒ 15 = -42 - 19y
⇒ 19y = -42 - 15
⇒ 19y = -57
⇒ y = -57 ÷ 19
⇒ y = -3
Therefore, x = 1 and y = -3

to get the equation of any straight line, we simply need two points off of it, so let's use the points in the picture below.
[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{9}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{9}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{4}{2}\implies 2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{5}=\stackrel{m}{2}(x-\stackrel{x_1}{1})[/tex]
now, if we use the last point from the table, namely (x , 17), we can see that x = x and y = 17, so let's plug those in the equation
[tex](17)-5=2(x-1)\implies 12=2x-2\implies 14=2x\implies \cfrac{14}{2}=x\implies 7=x \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (7~~,~~17)~\hfill[/tex]

the area of the triangle below is 29.25 square centimeters the height is 6.5. what is the length of the base?
Answer: 9
Step-by-step explanation:
½bh = 29.25
½ × 6.5 × b = 29.25
B= 29.25/ 3.25
The length of the base of the triangle is 9 centimeters.
What is the base length of the triangle?The area of a triangle is simply expressed as half base multiplied by height.
Area A = 1/2 × base length × height
Given the dimensions of the triangle:
Area A = 29.25 square centimeters
Height = 6.5 centimeters
Base length =?
To find the height of the triangle, plug the given values into the above formula and solve for h:
Area A = 1/2 × base length × height
29.25 = 1/2 × base length × 6.5
29.25 = base length × 3.25
Base length = 29.25 / 3.25
Base length = 9 cm.
Therefore, the base length measures 9 centimeters.

Convert the angle \frac{11\pi}{12} 12 11π radians to degrees
The angle 11π/12 radian after converting it to degree it become 165 degree.
What is an angle?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°

How to find the density and volume?She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width of 8.75 inches, a length of 8.75 inches, and a height of 23 inches.
The hot coffee has a density of 5.8 oz/in³ and the cold coffee has a density of 3.5 oz/ in³.
Then the volume of the coffee in each tank will be
We know that the dimension of both tanks is equal. Then the volume will remains equal.
Volume = L × B × H
Volume = 8.75 × 8.75 × 23
Volume = 1760.9375 ≅ 1760.94 in³
Then the mass of the coffee in each the tank will be
The mass of hot coffee will be
Mass = Density × Volume
Mass = 5.8 × 1760.94

The graph of a quadratic equation is shown here, and the intercepts with the axes are marked. Explain how you can use the graph to write the polynomial as a product of linear factors C(x - x1)(x - x2). Be sure to state the values of x1 and x2.
The graph is a quadratic function, and the equation of the function is C(x) = (x + 4)(x - 3)
How to determine the equation of the graph?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)
