Richard goes on a 6-mile jog one morning. He jogs the first two miles at an average speed of 6 mph. He progressively slows down;

uysha [10]

Answer:

Average speed = 4 mph

Step-by-step explanation:

Given as

Total distance to travel = 6 mile

now, for first 2 mile the avg speed = 6 mph

for next 2 mile the avg speed = 4 mph

and for rest 2 mile the avg speed = 3 mph

so, the average speed of the Richard = $\frac{3}{\frac{1}{6}+\frac{1}{4}+ \frac{1}{3} }$

Total Avg speed = $\frac{3}{\frac{9}{12} }$

Or, = $\frac{3}{9}$ ×12

= 4

So the total Average speed = 4 mph (Answer)

F(t)=3-2t.2t+t write in standard form

VMariaS [17]

<h2>Hello!</h2>

The answer is: $f(t)=-4t^{2}+t+3$

Since we are given a quadratic function, we need to write it using the standard form of quadratic function (parabola).

The given function is:

$f(t)=3-2t.2t=+t$

<u>The standard form</u> of a parabola is:

$f(t)=a^{2}+bx+c$

Where,

a is equal to the quadratic variable coefficient

b is equal to the linear variable coefficient

c is the constant number

So, writing the function in the standard form will be:

$f(t)=3-2t*2t+t=3-4t^{2}+t=-4t^{2}+t+3$

$f(t)=-4t^{2}+t+3$

Where,

$a=-4\\b=1\\c=3$

Have a nice day!
