To multiply, you multiply across. So it would be 3×1=3 and 10×6=60
Which will result in
but in order to simplify it, you find a common factor. The common factor is 3. 3÷3=1 and 60÷3=20
The answer is
Answer:
year 2000: P = 50
year 2004: P = 24
Step-by-step explanation:
t is the number of years since 2000, so for the year 2000, we have that t = 0.
Using this value in the equation, we find that:
P = -6 * 0 + 50 = 50
The price of the stock in year 2000 is 50.
For the year 2004, we have that t = 4, so using this value in the equation for P, we have:
P = -6 * 4 + 50 = -24 + 50 = 26
The price of the stock in year 2004 is 24.
Answer:
- sin(4a) = -24/25
- cos(4a) = 7/25
Step-by-step explanation:
Your calculator can tell you these values:
sin(4a) = sin(4·arctan(3)) = -0.96 = -24/25
cos(4a) = cos(4·arctan(3)) = 0.28 = 7/25
_____
Some useful trig identities are ...
sin(2a) = 2tan(a)/(1 +tan(a)^2)
cos(2a) = (1 -tan(a)^2)/(1 +tan(a)^2)
Filling in the given value for tan(a), we find ...
sin(2a) = 2(3)/(1+3^2) = 6/10 = 3/5
cos(2a) = (1 -3^2)/(1 +3^2) = -8/10 = -4/5
Now, double-angle formulas are useful:
sin(4a) = 2sin(2a)cos(2a) = 2(3/5)(-4/5) = -24/25
cos(4a) = 1 -2sin(2a)^2 = 1 -2(3/5)^2 = 7/25
The desired trig function values are sin(4a) = -24/25; cos(4a) = 7/25.
Answer:
39 athletes
Step-by-step explanation:
There is a total of 45 people on the bus. This INCLUDES the athletes (A), 2 coaches and 4 managers.
Therefore, we need to sum A, 2 and 4 and equal it to 45:
2 + 4 + A = 45 so we need to used equation d.
To calculate how many athletes are on the bus, find the value of A:
2 + 4 + A = 45
Subtract 2 from both sides: 4 + A = 43
Subtract 4 from both sides: A = 39
