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:

<em>To begin, we know that the formula:</em>

b(a)=200-0.75a    Eqn(1).

<u>is equivalent to a linear equation of algebraic form denoted as:</u>

y=k+mx                  Eqn(2)

<em>as such that  Eqns (1) and (2) relate as follow:</em>

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

x ⇔ a: is our Independent Variable<em>, </em>in this case the <em>Age of the Person</em>

m ⇔ 0.75: denoting the<em> Rate of Change of the Age.</em>

k ⇔ 200: denoting our <em>Constant.</em>

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.

The distance traveled by a toy car can be modeled by D(t) = t3 − 3t2 + t − 3, where t &gt; 3 represents time in seconds. If the
Bogdan [553]

Answer:

t^2+1

Step-by-step explanation:

We are given that

Distance traveled by a toy car

D(t)=t^3-3t^2+t-3

Where t>3

Time taken by car =t-3 seconds

We have to find the expression which represents the speed of the toy car.

We know that

Speed=\frac{Distance}{time}

Using the formula

Speed=\frac{(t^3-3t^2+t-3)}{t-3}

Speed=\frac{t^2(t-3)+(t-3)}{t-3}

Speed=\frac{(t-3)(t^2+1)}{t-3}

Speed=t^2+1

Hence, the expression  which represents the speed of the toy car

t^2+1
