The Baker formula estimates the maximum heart rate, in beats per minute, of a person who is

seropon [69]

Answer:

For a=16, the Maximum Heart Rate is 188 Beats Per Minute.

Step-by-step explanation:

To begin, we know that the formula:

$b(a)=200-0.75a$ Eqn(1).

is equivalent to a linear equation of algebraic form denoted as:

$y=k+mx$ Eqn(2)

as such that Eqns (1) and (2) relate as follow:

$y$ ⇔ $b(a)$ : denoting our Dependent Variable, in this case Max. Heart Rate in Beats Per Minute

$x$ ⇔ $a$ : is our Independent Variable, in this case the Age of the Person

$m$ ⇔ $0.75$ : denoting the Rate of Change of the Age.

$k$ ⇔ $200$ : denoting our Constant.

Now in the question our value of $b(a)$ is given as 188 beats per minute, which by plugging in Eqn(1) gives:

$200-0.75a=188$

from which we can solve to obtain the value of $a$ as follow:

$-0.75a=188-200$ Gather similar terms on each side

$-0.75a=-12\\$ Simplify

$a=\frac{-12}{-0.75}$ Solve for $a$

$a=16$

Which tells us that at the Age of 16, the Max. Heart Rate is 188 Beats Per Minute.

Answer:

The Answer Is A

Step-by-step explanation:

The Harappan civilisation is also called The Indus Valley Civilisation, this is because they built their cities along the Indus river. The reason behind this location can be found in the rest of the "Old World" civilisations like Mesopotamia or Egypt, the first built their cities along the rivers Tigris and Euphrates, the second along the Nil;: their respective civilisations thrived because the overflowing of their respective rivers produced favorable conditions for agriculture, their main support.

Determine is the solution set for the system of equations shown is the empty set contains one point or is infinite X+2y=0; 2x+4y

Sedaia [141]

We can use elimination to solve the system:

x+2y=0 Multiply the first equation by negative 2 so we can eliminate
2x+4y=0

-2-4y=0 Add them, -2X+2X= 0, -4Y+4Y= 0
2x+4y=0

0=0

Since 0 is indeed equal to 0 you have INFINITELY MANY SOLUTIONS.

you could also put both equation in slope intercept form and see if the slopes and Y-intercept are the same.
