If f(x)=4^x+4, then calculate f(0)

f(0) = 5

Step-by-step explanation:

Note that = 4

To calculate f(0), substitute x = 0 into f(x), that is

f(0) = + 4 = 1 + 4 = 5

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
