Answer: 109.5 km/ hr
Step-by-step explanation:
Distance = 73 km
Time = 40 minutes = 40/60 = 2/3 hours
Speed = Distance / time
= 73 / 2/3
= 73 x 3/2 = 219 / 2 = 109.5 km/hr
Answer:
Days- 9
Hours- 208
Minutes- 12,459
Step-by-step explanation:
For minutes,
747,533 ÷ 60 = 12,458.883 ≈ 12,459 minutes
For hours,
60 minutes to pass an hour so, 60 × 60 = 3600 minutes
747,533 ÷ 3600 = 207.648 ≈ 208 hours
For days,
1 day = 24 hours
1 hour = 3600 beats
24 × 3600 = 86400
747,533 ÷ 86400 = 8.652 ≈ 9 days
Translation of 7 units to the right ⇒ subtract 7 units to the argument ⇒ f(x-7)
Translation of 5 units up ⇒ add 5 units to the function ⇒ f(x) + 5
g(x) = f (x-7) + 5 = (x-7)^2 + 5
The subtraction of 7 units to the argument of the function (this is x) translates the function 7 units to the right.
Adding 5 units to the function f, translates the graph 5 units up.
After a reflection across line L1, x = 2, the afterimage is
Z' (2 + (2-1) ,1) = Z' (3, 1)
After a reflection across the line L2, y-axis, the afterimage is
Z'' (3, 0 + (0 - 1) = Z'' (3, -1)<span />
Answer: Both students are correct.
Explanation:
In rotation a shape is rotated about a fixed point and it does not affect its measurements. it only changes its position.
Now, When Marcus rotated the 
about point S then this process did not affect its shape and size this is why he got the 
which is congruent to the .
In reflection, when a shape reflected across a line then its all points get reflected across this line. But it also does not affect the measurement of the shape.
So, when Sam mapped by the reflection of then the measurement of the did not change. And, he also got the congruent triangle.
Thus, we can say that, Both Marcus and Sam are right.
