No instructions?  I'll assume you want the unit rate.

4 miles in 36 minutes = 4/36 miles in 1 minute, or 1/9 mile in 1 minute.


1 3/4 mile in 20 minutes?  Multiply both figures by 3:

7 miles in 60 minutes, or 7 miles in 1 hour, or 7 mph.

The function N(X) = 90(0.86)* + 69 can be used to predict the temperature of a
dezoksy [38]

Answer: -8.93

Step-by-step explanation:

Given the function:

N(X) = 90(0.86)^x+ 69

X in the interval [0, 6]

For X = 0

N(0) = 90(0.86)^0 + 69

90 + 69 = 159

For X = 6

N(6) = 90(0.86)^6 + 69

90(0.404567235136) + 69

= 105.41105116224

Therefore, average change of change in temperature ;

(temp 2 - temp 1) / ( time 2 - time)

(105.41105116224 - 159) / (6 - 0)

= - 53.58894883776 / 6

= - 8.93149147296

= - 8.93

Which graph shows the axis of symmetry for the function f(x) = (x – 2)2 + 1?
OleMash [197]

Given function is

f(x)=(x-2)^2+1

Now question says to find the graph that shows the axis of symmetry for the given function.

Graph is missing but I can help you to find the correct graph.


Given equation is in the vertex form whose formula is given by

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

Comparing given function with above formula, we get:

a=1, h=2 and k=1.

For the vertex formula f(x)=a(x-h)^2+k, we know that axis of symetry is given by equation:

x=h

So for the given function, axis of symmetry will be x=2

Graph of x=2 will be a vertical line crossing x-axis at x=2

So you just need to find the graph from given choices which contains a vertical line crossing x-axis at x=2.
