Answer:
4
Step-by-step explanation:
h(7)= 7²-1= 49-1= 48
f(h(7))= 48/3 -12
= 16-12
= 4
Take a look at the diagram below.
This problem looks like a great candidate for using the Law of Cosines.
If you know two sides, you can find the third side from the angle opposite or vice versa. Should the sides be a, b, and c, and their opp. angles A, B, and C...
a² + b² - 2ab(cosC) = c²
Let's plug in what we know...a = 55, b = 25, and m<C = 25".
55² + 25² - 2(55)(25)(cos(25")) = c²
One thing to note is that our angle measure is in <em />seconds. Unless you're using Google's built in calculator, you'll wind up having to convert to degrees. 60 seconds in a minute, 60 minutes in a degree...blahblahblah.
Anyways, cos(25") comes out to be practically 1. (0.99999993)
Let's get evaluating.
3025 + 625 - 2750(1) = c²
3025 + 625 - 2750 = c²
900 = c²
30 = cThe tree is
30 meters from the fence post.
A. 28
b. 67.45 repeating
c. 71.4
Answer:
the answer is D just click on it man or lovely woman
Step-by-step explanation:
Yes.<span>a multiple of 3=add the numbers so 8 plus 1 is 9 and divide that by 3 it works
2.no.</span>fthe number formed by its last two digits is divisible by 4, the original number is as well.
3.no.take the last digit, double it, and subtract it from the rest of the number.
4.yes.<span>Add the digits. If that sum is divisible by nine, then the original number is as well.</span>
<span>5.no . has to work with both
</span><span>Multiple of 2 --> is even (ends with 0, 2, 4, 6 or 8) </span>
<span>Multiple of 3 --> digits add up to a multiple of 3. </span>
