Please help ASAP Solve 2^(x − 1) = 11 for x using the change of base formula log base b of y equals log y over log b.
A) −0.711

B) 1.289

C) 2.459

D) 4.459

D

Step-by-step explanation:

2^(x-1)=11

(x-1)*ln(2)=ln(11)

x-1=ln(11)/ln(2)

x=ln(11)/ln(2)+1

get a calculator and evaluate this, you'll get

50-38=12

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
