Answer:
C
Step-by-step explanation:
The absolute value always returns a positive value, that is
| - a | = | a | = a, thus
| 3 
| = 3 → C
Answer:
D) 30
Step-by-step explanation:
L and V are the same so you have to rotate triangle LMN so that L points up like V. Next look at the hypotenuses, they are 40 and 24. set them up it a proportion like so 40/24. Then simplify to get 5/3. Now you multiply that by 18 to find the missing side with is 30.
If you can make my answer the brainliest that would be much appreciated. Thanks!
4 3/5 ≈ 5
1 1/5 ≈ 1
(4 3/5) +(1 1/5)
≈ 5 +1
≈ 6 . . . . . . . . . . . the estimated sum rounded to whole numbers
_____
Additional information:
As a refinement to your estimate, you can estimate the error. The first number is 2/5 less than 5. The second number is 1/5 more than 1, so the errors add up to
.. (2/5) +(-1/5) = 1/5
That is, your "estimate" of 6 is actually too high by 1/5. You can refine that estimated value by subtracting 1/5. 5 4/5 would be a closer "estimate."
Answer:
f(g(x)) = 3(2x^3 -2)^2 - 4x + 2, and f(g(3)) = 3[2(3)^3 -2]^2 -4*3 -2 = 8102
Step-by-step explanation:
because for f(g(x)), the g(x) is the input of f(x), so put 2x^3 -2 into 3x^2 -4x +2, and you will get f(g(x)). because g(3) is the input of f(x), so find g(3) first, the answer is 52, and then put it back into f(x) which will be f(52) =[3(52)^2 - 4(3) +2], then the answer should be 8102.
The value of csc theta from the given diagram is 15/12
<h3>Application of SOH CAH TOA</h3>
The given triangle is right angle triangle. According to trigonometry identity
csc theta = 1/sintheta
Given
- Opposite = 12
- Hypotenuse = r
sin theta = 12/r
Determine the value of r
r² = 9² + 12²
r² = 81 + 144
r² = 225
r = 15
sin theta = 12/15
Determine the value of csc theta
csc theta = 15/12
Hence the value of csc theta from the given diagram is 15/12
