Two vectors beginning at the same vertex of a triangle are 〈2,1〉 and 〈1,-7〉. Choose the correct classification of the triangle. Acute
Obtuse
Right
Equilateral

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

false

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
