Answer:
∠BAC = 105°
Step-by-step explanation:
2(5x) = 9x+21
10x = 9x+21
reduce:
x = 21
∠BAC = 5x = 105°
Answer:
I'm pretty sure the answer to the third question is C
Step-by-step explanation:
We are solving for h(g(x)).
We already know that g(x) is equal to x^2+4.
So know, we can simplify our expression, h(g(x)), to h(x^2+4).
We also know that h(x)=1/x
we simply substitute x for x^2+4, giving us an answer of 1/(x^2+4)
The answer is B i did this before hope this helps
Answer:
4.0 x 10^2
Step-by-step explanation:
We are finding the quotient of the numbers in scientific notation. At first, we can write the quotient as

Let's try to rewrite the numbers in scientific notation. We can rewrite 1.06 x 10^7 into

which are the same. We can also rewrite 2.65 x 10^4 into

Now we have

1060 divided by 265 results to 4. And if we divide scientific notation, we just subtract the exponents on 10s. In this case, we have 4 and 2. 4-2 yields 2.
Hence, the final answer to this problem is
