Step-by-step explanation:
sin(s+t) = sin(s)+cos(t) which results
(sin(s)×cos(t))/(cos(s)cos(t)) + (cos(s)×sin(t))/(cos(s)cos(t))
knowing that tan=sin/cos and that cos/cos=1 and sin/sin=1
resulting tan s ×1 + tan t × 1 = tan s + tan t
Answer:
D. $674.68
Step-by-step explanation:
We will use the well known equation for compound interest

Where
is the final total
is the principal amount (starting total)
is the interest rate as a decimal
is the number of times the interest is compounded each year
the number of years
Plugging in what we know from the question:

So the answer is D.
Hope this helps!
Answer:
Your answer is 31 for 1 shot points, and 45 for 2 shot points.
Step-by-step explanation:
Answer:
The answer is D).
Step-by-step explanation:
I am assuming that you are talking about exponents and powers. So I assumed that:
A) was 4.325 * 10^-9,
B) was 4.325 * 10^-6,
C) was 4.325 * 10^6,
D) was 4.325 * 10^9
I just went for gusto, and multiplied/solved answer D), and it was correct. I just punched into calculator, and boom. 4,325,000,000. I hope this helps!

Let's call the younger student's age A and the older student's age B. The teacher's age will be T.
B = 2A
T = 5B
T+5 = 5(A+5)
Simplify the last equation.
T+5 = 5A+25
T = 5A+20
Now we have two equations solved for T, so we can set them equal to each other.
5B = 5A + 20
We can plug 2A in for B
5(2A) = 5A + 20
10A = 5A + 20
5A = 20
A = 4
To find T, we plug 4 in for A in T = 5A + 20
T = 5(4) + 20
T = 40
The answer is 40 years old.
