Answer:
270 first question's answer
Step-by-step explanation:
Solution at attachment box
Total surface area of cuboid is = 12x18x2 + 10x12x2 +18x10x2
=432+240+360
=1032
Surface of the 1 cube =2x2x2 = 8
Surface of the all cubes = 8x270 = 2160
You can eliminate c) because it only had one inequality symbol. Then you subtract 1 from both sides to get x by itself. 6 divided by 3 gives you two. You now have choices A and B. The answer will be B because x represents all values that are less than 2, not just 2 plotted on the number line..
You're answer to the following question: "Which Point Must be the Centre of the Circle?" Is C
Answer:
Part A:
0 = -16x^2 + 22x + 3
x intercepts = (-0.125, 0) and (1.5, 0)
Part B:
It's going to be a maximum. This is because, the graph opens to the bottom. The coordinates are approximately (0.69, 10.56).
Part C:
I would plug in various x values, then solve for the y value. Repeat the process, and get a good idea of the graph.
Hope this helps!
Answer:
- X + Y = 5
Step-by-step explanation:
Linear function is:
y= mx+b or ax+bx+c= 0
Only option from the listed matching the above condition:
==============
Max 4x + 3 XY - not a linear function
s. t. 2x + Y<50 - inequality
X-4Y >6 - inequality
1.5 X2 + 6Y > 21 - inequality, quadratic
- X + Y = 5 - yes
5X +3underroot7 380 - not a linear function
X, Y>0
