a.) The orientation of ABCD is clockwise, as is the orientation of A'B'C'D'. This means the transformation involves a even number of reflections (may be 0). The orientation of AB is North, and the orientation of A'B' is West, so a rotation of 90° CCW (or equivalent) is involved. We can find the point of intersection of the perpendicular bisectors of AA' and BB' (at (-1, -1)) to determine a suitable center of rotation.
ABCD can be transformed to A'B'C'D' by ...
- rotation 90° CCW about the point (-1, -1)
b.) Rotation by 90° can also be accomplished by reflection across a diagonal line. Since we want the orientation to remain unchanged, we need another reflection to put the figure into its final position. A suitable alternate sequence for mapping ABCD to A'B'C'D' is ...
- reflection across the line y=x
- reflection across the line x=-1
Answer:
C
Step-by-step explanation:
put x^5=u
Answer:
The value of the function is 2 when x=-4 or x=0.
Step-by-step explanation:
Let makoha contribute x then njao contributes x * 3/2 = 1.5x
and odhiambo contributes 1.5x * 2.5 = 3.75 x
so we have the equation x + 1.5x + 3.75x = 120000
6.25x = 120000
x = sh 19,200 which is the amount for makhoa
Answer : amount contributed by odhiambo = 19,200 * 3.75 = sh 72,000
Answer:
17%, or $25.50
Step-by-step explanation:
If Ricardo has already saved 83% of the money, then he needs to save 17% more, because 83% + 17% = 100%
So what you need to do to figure out the answer is to find out 17% of $150
You first have to convert 17% into decimal form which is 0.17.
Then, you multiply 0.17 × 150 = 25.5
Ricardo needs $25.50 to buy the skateboard.
Hope this helped.
