Answer:
polygon must have 18sides
Answer: B
Step-by-step explanation:
If there is a change in something it normal means you subtract 1 number from another.
In this case the two values were 5 and -11.
At midday for answer b, it was 5 and at midnight it -11. It then wants to know the change in temperature which would result in an expression of 5-(-11).
Answer:
Answer is 50 meters
Step-by-step explanation:
Solution:
Height of the building (h)= 90 meters.
Time taken by the ball to reach the ground (t) = 3 seconds
According to the statement;
h = kt²
90=k(3)²
90=k(9)
90=9k
Divide both the sides by 9
k=10
h=kt²
Put the value time (t)=2 in the equation
h=10(2)²
h=10(4)
h=40 meters
Distance from the ground = 90 - 40
=50 meters.
Thus the correct option is 50 meters....
no. the word technology spans every invention ever created. we don't.
