Answer:
We have the equation:
P(t) = 100 - 10*t
where t is the number of hours.
at t = 0, we have:
P(0) = 100 - 0 = 100
so at the initial time, we have 100% of the battery power.
Now with this equation we can find the numbers of hours that we have left in our phone, this is finding the time t at which the power left is equal to zero:
P(t) = 0 = 100 - 10*t
10*t = 100
t = 100/10 = 10
So the battery power will last for 10 hours.

Answer:
k(w) = (w +3)²
Step-by-step explanation:
The name of the function is k, and its input is w, so the left side of the equal sign will be ...
k(w)
This is said to be the square of the sum w+3, so the right side of the equal sign will be ...
(w +3)²
The function equation in function notation is ...
k(w) = (w +3)²
probably this would help.
Percent means parts out of 100
65%=65/100=0.65
'of' mens multiply
'is' means equals or '='
65% of what number is 26
0.65 times what=26
divide both sides by 0.65
0.65/0.65 what=26/0.65
1 what=40
what=40
numbe ris 40
