Matthew is training to participate in a half marathon. the table below shows the number of miles he runs in weeks 1 and 2. week number of miles run 1 12.5 2 13.5 each week, matthew increases the number of miles he runs in the previous week by the same percent. how many miles does matthew run in week 3? do not round your answer. a0 miles

There is 14.5 miles run by Matthew in week 3.

Step-by-step explanation:

Since we have given that

Week   Number of miles

1                         12.5

2                        13.5

First we will find the slope :

(1,12.5) and (2,13.5)

So, Slope would be

So, equation of line would be

We need to find the number of miles in week 3.

So, we put x = 3,

Hence, there is 14.5 miles run by Matthew in week 3.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
