Answer:
Step 1 of 5
(1). Familiarize.
<em>The energy in the slice of carrot cake is described in terms of the requirement of energy of an adult on a day.
</em>
<em>
</em>
<em>So we let x calories = the requirement of energy of an adult on a day.</em>
<em>3/4 ( x ) calories
</em>
<em>
</em>
<em>Then is the energy in the slice of carrot cake.
</em>
<em>
</em>
<em>The energy in the slice of carrot cake is 1560 calories.</em>

5^2 + x^2=8^2
25+x^2=64
X=6.2

The answer is ✰ 4 ✰
Step-by-step explanation:
:))
The range is the ouutput from inputing the input
basically
25=k²+2k+1 and 64=k²+2k+1
the values that satisfy both equations (not at the same tim) are the valuess that are the domain
solve each
25=k²+2k+1
minus 25 both sides (or recognize the perfect square trinomial, but anyway)
0=k²+2k-24
factor
0=(k+6)(k-4)
set to zero
k+6=0
k=-6
k-4=0
k=4
k=-6 or 4
64=k²+2k+1
minus 64 both sides
0=k²+2k-63
facor
0=(k-7)(k+9)
set to zer
k-7=0
k=7
k+9=0
k=-9
k=-9 or 7
so the domain has the numbers
-9,-6,4,7
it seems we only want the positive square roots so
answer is {4,7} is the domain
