svetoff [14.1K]

Answer: Peters average speed in m/min is 294.1176 m/min


Step-by-step explanation:


Peter participated in a 5000m race and finished the race in 17 min.


Speed is calculated as Distance/Time


Peters average speed in m/min = Distance covered in m / Time taken in minutes

= 5000/17

= 294.1176 m/min


Therefore, Peters average speed in m/min = 294.1176 m/min


Hope it helps.


Thank you :)

What is the focus of the parabola with equation y = x2?
hammer [34]

Answer:

focus=(0,\frac{1}{4})

Step-by-step explanation:

We are given equation of parabola as

y=x^2

we can also write as

y=1(x-0)^2+0

now, we can compare

y=a(x-h)^2+k

and find a , h , and k

a=1

h=0

k=0

now, we can use focus formula

focus=(h,k+\frac{1}{4a})

now, we can plug values

focus=(0,0+\frac{1}{4\times 1})

focus=(0,\frac{1}{4})

11 more than four times a number is 39
Aliun [14]

Hello!

Your answer is: 7

(X = "<em>A number</em>")

<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39

to solve, first subtract 11 from both sides:

4X = 28

then divide both sides by 4 to get:

X = 7

I hope this helps, and have a nice day!
