Answer:
a reasonable estimate is $1500
Step-by-step explanation:
16 + 12 is about 30
$53 is about $50
30 x 50 = 1500
no because the absolute value of 1/4 is 1/4 and the absolute value of -4 is 4
absolute value is just a positive version of the number inside of the symbol
Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
Answer:
No.
Step-by-step explanation:
A scale copy would see that both the x and y amount would be scaled proportionally. In this case, the x goes across 5 for figure A, and does the same for Figure B. On the other hand, the scaling for y is 2 for figure A, while it is 5 for figure B.
If it is a scale copy then.
If Figure A have the scaling of: 3, 5, 5, x, then Figure B, if given one scale of 5, should have
3:5
5:8.33
5:8.33
x:(x * ~1.67)
Therefore, the scaling is off.
B) 14 is the correct answer
