Hi!
I’d use Pythagora’s theorem here. If PR is 6, PQ is also 6. PQO is a right angle.
OQ^2=6.8^2 - 6^2
OQ^2=46.24 - 36
OQ^2=10.24
OQ= sqrt 10.24
OQ=3.2
Answer:
option b
reflection over the line y = x
Step-by-step explanation:
Matrix for every option is mention below
a)
rotation of 90° counter clockwise about the origin
0 -1
1 0
b)
rotation of 180° about the origin
-1 0
0 -1
c)
for a reflection in the line y=x
0 1
1 0
d)
translation 1 unit left and 1 unit up
1 0
0 1
Answer:
It decreases
Step-by-step explanation:
Given the expression: 70-3g
- When g=1, 70-3g=70-3(1)=70-3=67
- When g=2, 70-3g=70-3(2)=70-6=64
- When g=3, 70-3g=70-3(3)=70-9=61
- When g=4, 70-3g=70-3(4)=70-12=58
- When g=5, 70-3g=70-3(5)=70-3=55
From the above, notice that as g increases, the value of the expression decreases.
Answer:
Option 3 or Option 4.
Step-by-step explanation:
I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.
On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.
In case you only can answer with one, I'll say is option 3, hope it helps!
