I’m working on it right now, so give me some time please
Answer:
Step-by-step explanation:
<u>Heron's Area formula:</u>
- A = , where s is semi-perimeter
- s = 1/2(a + b + c)
We are given two sides and the included angle.
<u>Use the law of cosines to find the missing side:</u>
- a² = b² + c² - 2bccos A
- a² = 77² + 41² - 2*77*41*cos 79
- a² = 6405
- a = 80 (rounded)
<u>Now find the value of s:</u>
- s = 1/2(80 + 77 + 41) = 99
<u>Find the area:</u>
- A = = = 1549.24

Answer:
Step-by-step explanation:
Note the f(0) = 9
and f(1) = 15
Since, f(x) = abˣ substituting for x, we get:
9 = f(0) = a . b⁰ = a
⇒ a = 9
Now, f(1) = 15
⇒ 15 = a . b¹
⇒ 15 = 9 . b
⇒ b =
Therefore,
Hence, the answer.
