Benwa bicycles 7 miles west to get from his house to school. After school, he bicycles 6 miles north to his friend Dante's house. How far is Benwa's house from Dante's house, measured in a straight line? If necessary, round to the nearest tenth. *

9.2 miles

Step-by-step explanation:

Patjagorean therom. 6squared plus 7squared equals c squared. 36+49=squared. it would be 9.2

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
