Answer:
x ≈ 35.3
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan67° = = ( multiply both sides by 15 )
15 × tan67° = x , then
x ≈ 35.3 ( to the nearest tenth )
Option B:
f(3) = 5
Solution:
Given function:
- If x value is less than –2, that is –3, –4, –5, –6, ... then f(x) = –x².
- If x value is greater than or equal to –2 and less than 0, that is –2 and –1 then f(x) = 3.
- If x value is greater than or equal to 0, that is 0, 1, 2, 3,... then f(x) = x +2.
<u>To find the value of f(3):</u>
Here x value is 3 which is greater than 0 (3 > 0).
Therefore, f(x) = x + 2.
Substitute x = 3 in the above function.
f(3) = 3 + 2
f(3) = 5
Hence option B is the correct answer.
Answer:
A=-8 and B=-2
Step-by-step explanation:
That would be 3/3, which can be simplified one more time to just 3!
