David hikes 21/4 miles in 1/2 an hour. What is his rate in miles per hour? At this rate, how long will it take him to walk 18 mi
harkovskaia [24]

Answer:

A) speed = 10.5 miles per hour

B) Time taken by him = 1.714 hours

C)  Distance = 10.5 mph × 7 hours = 73.5   miles

Step-by-step explanation:

Given as :

The distance cover by David = \frac{21}{4} miles = 5.25 miles

The time taken by David        = \frac{1}{2}  hours  = 0.5 hours

Let the speed                          = x mile per hour

So, Distance = Speed × Time

A)or,  Speed = \frac{Distance}{Time}

Or,  Speed = \frac{5.25}{0.5}

∴     speed = 10.5 miles per hour

<u>B) Again The Distance cover by him = 18 miles</u>

SO, with speed 10.5 miles per hour

The Time taken by him =  \frac{Distance}{speed} hours

Or, Time taken by him =  \frac{18}{10.5} hours

∴    Time taken by him = 1.714 hours

<u>C) Again the Time taken by him = 7 hours   </u>

So, Distance cover by him with speed 10.5 mph

Or, Distance = 10.5 mph × 7 hours = 73.5   miles

A) speed = 10.5 miles per hour

B) Time taken by him = 1.714 hours

C)  Distance = 10.5 mph × 7 hours = 73.5   miles   Answes

What is an equation of the parabola with vertex at the origin and focus (0, 0.75)?
morpeh [17]

Answer:

x^{2} =3y

Step-by-step explanation:

Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form

x^{2} =4py

Because the parameter p is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.

Replacing the parameter value, we have

x^{2} =4(0.75)y\\x^{2} =3y

Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is x^{2} =3y.
