Graph the piecewise function (20 points!) (image provided below)
1 answer:
check the picture below.
notice, the hollow dot endpoints, is where the subfunction does not include that value of "x", and where the dot is a solid dot, that value is included in the subfunction.
so the piece-wise is simply the composition of all its subfunctions, in this case 3 subfunctions, within their range, notice the lines continue on the dashed line part, but that part is not included in the piece-wise because is outside the range provided for "x".

Answer:
volume 1050
surface area 859
Step-by-step explanation:
volume is length times width times height (7*25*12)/2
surface area is area of all the sides added together
2(25*12)+(12*7)+ 2()
Option B: 4.0 cm is the value of w
Explanation:
It is given that ,
,
and
Using the law of sines, we have,
Substituting the values, we have,
Cross multiplying, we get,
Simplifying, we have,
Dividing both sides by 0.515, we have,
Thus, the value of w is 4.0 cm
Hence, Option B is the correct answer.
