Answer:
b
Step-by-step explanation:
Answer:
C is better
Step-by-step explanation:
42mph is greater than 32mph
So a good trick to remember with trig is "SOH CAH TOA"
Sine = Opposite/Hypotenuse
Cosine = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent
For here, since we have the opposite side and are solving for the adjacent side, we are using tangent. Our equation will look like this:
Firstly, cross multiply:
Next, divide both sides by tan(25), and your answer will be x = 21.4.
The common ratio between terms is 3, so the sequence has general -th term
for . The term exceeds 7000 when
which means the first time exceeds 7000 occurs when . Indeed,
while the previous term would have been
Answer:
See explanation, and ask for more details if unclear!
Step-by-step explanation:
The perfect square of this equation is , since the square would be . 1/4=4/16, meaning that you can set up the equation in the following way:
Take the square root of both sides:
Add 1/2 to both sides:
. Hope this helps!
