Answers

Answer:

a) Log ( 2 ) = 4t Log ( 83/80 )

b) 4.7 years

Step-by-step explanation:

Attached below is the detailed solution

a) exponential statement in log form for an investment at 15% quarterly

Log ( 2 ) = 4t Log ( 83/80 )

n = 4 ,  r = 15

b) using change to base  to find double time in yr

Double time in yr

x= 43
do 49+88 then subtract that from 180

Answer:

x = 43

Step-by-step explanation:

First, make the equation which is

x + 49 + 88 = 180

Next, add 49 + 88 which is 137

Now you have x + 137 = 180

Subtract 137 from both sides and you get your final answer:

x =43

A builder had been asked to lay an octagonal patio using square paving slabs. To do this, he cuts some of the bricks in half down the diagonal. Each paving slab is 1m wide. What will the perimeter of the patio be

Answers

Assuming you want an expression for the possible total area of the patio: if "completed" would be a rectangle of dimensions n, m: each must be >=3 to allow for octagonal corners. But each of the 4 corners must be missing, that's diagonals comprising (1/2)a^2, (1/2)b^2, (1/2)c^2, and (1/2)d^2, where a,b,c, and d must be variously limited and co-limited so as to allow at least 1 linear side of the original rectangle to be exposed. So A = (n*m)-(1/2)a^2-(1/2)b^2-(1/2)c^2-(1/2)d^2 as an expression.
Now, imagine replicating your possible (potentially irregular) octagons onto a plane and juxtaposing them so as to create a paved network. What geometric properties might such a network have? You now have a miniscule idea what nature does with silicate networked minerals, except that takes place in 3-D, with tetrahedra of SiO4 .

Answers

Answer:

Step-by-step explanation:

f ( x ) = x^2 - 2x - 3

f ( x ) = 5

x^2 - 2x - 3 = 5

x^2 - 2x - 3 - 5 = 0

x^2 - 2x - 8 = 0

x^2 + 2x - 4x - 8 = 0

x ( x + 2 ) - 4 ( x + 2 ) = 0

( x - 4 ) ( x + 2 ) = 0

x - 4 = 0

x = 4
