Answer:
option D. Neither
Step-by-step explanation:
y-4=7(x-6)
using (5,4):
4-4=7(5-6)
0=7(-1)
0=-7
using (6,5):
5-4=7(6-6)
1=7(0)
1=0
so option D is the answer
Answer:
-9
Step-by-step explanation:
x+2=-7
x+2-2=-7-2
x=-9
Answer:
The shortest walking route is through the diagonal AC: 102.89m
Step-by-step explanation:
One can go from A to C using 2 paths:
- ADC or ABC
- using diagonal AC and half of that inner circle.
We need to compute the length of each path.
1) ADC=AD+DC=80+50=130m
2) AC²=AD²+DC²=80²+50⁵=6400+2500= 8900m²
AC=sqrt(8900)=94.34m.
Note that the diagonal AC has a missing segment, whose length is the diameter of the inner circle. So the straight line has a length of: AC-d=94.34-15=79.34m.
Perimeter of half the circle=pi×r= 3.14×(15/2)= 3.14×7.5=23.55m
So, if one is using the diagonal to go from A to C, then he has to walk:
79.34+23.55=102.89m
Comparing the two routes: 130m vs 102.89m, we notice that the route using the diagonal AC is shorter.
Step-by-step explanation:
- (i) For cuboid shaped container:
(Given)
- Container is filled with water so the volume of water can be given by the following formula:
- Plugging the values of l, b and h in the above formula, we find:
- (ii) For solid right circular cylinder:
- radius (r) = a cm, h = a cm
- Formula for volume of cylinder is given as:
The correct answer is option D.
The polygon ABCD can be mapped on to WXYZ but first it must be enlarged and then it must be mirrored along BC.
The mirror image of ABCD along BC must be enlarged with a scale factor of 2 to map ABCD to WXYZ.
The scale factor is the ratio of the the object to be transformed to the object with which it is to be compared.
Here, the scale factor is 2 and we must enlarge the image of ABCD along BC to get the desired mapping.
