Answer:
≈ 66.5 m
Step-by-step explanation:
Using the sine ratio in the right triangle
sin12° =
=
( multiply both sides by 320 )
320 × sin12° = d , then
d ≈ 66.5 m ( to 1 dec. place )
Answer: x=3 isn't a function because multiple different inputs have the same outputs
Step-by-step explanation:
I dont know how to answer the first question since the dropdown is shown
Step-by-step explanation:
<u>Properties used</u>
- logₐ a = 1
- log aᵇ = b log a
- log ab = log a + log b
See the steps below
- - log (4*10⁻³) =
- - (log 4 + log 10⁻³) = (log 4 ≈ 0.6 rounded)
- - (0.6 - 3*log 10) =
- - (0.6 - 3*1) =
- - (0.6 - 3) =
- - (- 2.4) =
- 2.4
3-√11
This function is evidently a quartic - a function with 4 roots. The last root has been found using the quadratic formula however, the answer always comes in pairs because the formula is
{b+√(b^2 - 4ac)}/2a and {b-√(b^2 - 4ac)}/2a. Therefore the other root must be 3-√11
Answer: 13 comic books
Step-by-step explanation:
1st add 18 + 8 which equals 26
2nd subtract 130 - 26 which equals 104
3rd divide 104 / 8 because each comic book was $8
4th your answer is 13 comic books
