A rectangle is drawn so the width is 5 inches longer than

CaHeK987 [17]

Answer:

$length = l\\width = 5 + l\\Diagonal = 36\\diagonal^2 = (5+l)^2 + l^2\\36^2 = 25 + l^2 +10l + l^2\\1296 = 2l^2 +10l +25 \\2l^2 +10l=1271\\\\l_1=\frac{-10+2\sqrt{2567}}{2\cdot \:2},\:l_2=\frac{-10-2\sqrt{2567}}{2\cdot \:2}$

$l_1=\frac{-5+\sqrt{2567}}{2},\:l_2=\frac{-5-\sqrt{2567}}{2}$

clearly,

$l_{2} \ is \ a \ negative\ number$

So we consider

$l_{1} =\frac{-5+\sqrt{2567}}{2} = 22.83$

Therefore height = 22.8inches

Need help with geometric sequences <br> 30 points

NeTakaya

Answer:

$a_{n}$ = 6 $(5)^{n-1}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = 6 and r = 30 ÷ 6 = 5, thus

$a_{n}$ = 6 $(5)^{n-1}$
