The answer is D) All the steps and the answer are correct. :)
You can just solve using the steps to see if they are right. For example, is -1x17=-17? Yes.
Answer:
120°
Step-by-step explanation:
Opposite angles in a cross of 2 lines like this are equal;
A = 120 and B = D = 60°
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:
f(g(x)) = x^2 + 27.
Step-by-step explanation:
To find f(g(x)) we replace the x in f(x) by g(x) and simplify:
f(g(x)) = 7(x^2 + 2) + 13
= 7x^2 + 14 + 13.
= 7x^2 + 27.
-1000 is the answer to 5*10^-3
