Answer:

The friends live 285 miles apart.

Step-by-step explanation:

Let total distance in miles Sean needs to cover to visit his friend be = $x$

On first hour distance traveled in miles is = $\frac{1}{5}\ of\ the\ total\ distance = \frac{1}{5}.(x)=\frac{1}{5}x$

Distance left to cover after first hour = $x-\frac{1}{5}x$

On second hour distance traveled = 34 miles

Distance to still left to be covered = 194 miles

Total distance to be covered after first hour will be = $34\ miles+194\ miles$ = 228 miles

Thus, the equation can be given as:

⇒ $x-\frac{1}{5}x=228$

Multiplying each term with 5 to remove fractions.

⇒ $5x-5.\frac{1}{5}x=5\times228$

⇒ $5x-x=5\times228$

⇒ $4x=1140$

Dividing both sides by 4.

⇒ $\frac{4x}{4}=\frac{1140}{4}$

∴ $x=285$

Thus, the friends live 285 miles apart.

Answer:

$f(x)=-\frac{1}{8}(x-4)^2+3$

Step-by-step explanation:

The directrix given to us has equation,

$y=5$ and the focus is $(4,1)$ .

This means that the axis of symmetry of the parabola is parallel to the y-axis and has equation $x=4$ , because it must go through the focus.

This axis of symmetry of the parabola will meet the directrix at $(4,5)$ .

The vertex of this parabola is the midpoint of the point of intersection of the axis of symmetry and the focus.

Thus,

$V(h,k)=(\frac{4+4}{2},\frac{5+1}{2})$

$V(h,k)=(4,3)$ .

The equation is given by $(x-h)^2=4p(y-k)$ .

$(x-4)^2=4p(y-3)$ .

$|p|$ is the distance between the vertex and the focus, which is 2.

This implies that,

$p=-2$ or $p=2$

But the position of the directrix and the vertex implies that the parabola opens downwards.

$\therefore p=-2$ .

The equation of the parabola now becomes;

$(x-4)^2=4(-2)(y-3)$ .

$(x-4)^2=-8(y-3)$

We solve for y to obtain,

$y=-\frac{1}{8}(x-4)^2+3$

or

$f(x)=-\frac{1}{8}(x-4)^2+3$

Answer:

Dog Pogo will fetch the frisbee <u>12 times</u> in 4 minutes.

Step-by-step explanation:

Given:

Number of minutes required =2 minutes.

Number of times frisbee fetch by dog = 6 times

We need to find Number of times the dog can fetch the frisbee in 4 minutes.

First we will find number of frisbee fetch in minute.

In 2 minutes = 6 times frisbee fetched by the dog

so in 1 minute = Number of times frisbee fetched by the dog in 1 minute.

By using Using Unitary method we get;

Number of times frisbee fetched by the dog in 1 minute = $\frac{6}{2} =3$

Hence in 1 minutes the dog can fetch frisbee 3 times.

for 1 min = 3 times frisbee is been fetched by dog

So for 4 minutes = Number of times frisbee is been fetched by dog in 4 min.

Again by using Unitary Method we get;

Number of times frisbee is been fetched by dog in 4 min = $3\times4 = 12$

Hence Dog Pogo will fetch the frisbee <u>12 times</u> in 4 minutes.
