Answer:
Yes
Step-by-step explanation:
1/2 + 6/6
= (1*3)/(2*3) + 6/6
= 3/6 + 6/6
= 9/6
= 3/2
So the fraction 1/2 make the equation true.
Answer:
C and D
Step-by-step explanation:
Mathematically, a unit circle is one in which the value of the radius is 1 unit
Generally, for a unit circle we have it that;
r^2 = x^2 + y^2
where (x,y) represents the coordinates of a point on the unit circle
But from above, r = 1
Thus:
x^2 + y^2 = 1
Looking at option C, by squaring each coordinate, we have
(6/7)^2 = 36/49 and the second as 13/49
by adding both, we have
36/49 + 13/49 = 49/49 = 1
Thus, we have this as a coordinate on the unit circle
For the last option;
(5/13)^2 = 25/169 and (12/13)^2 = 144/169
Adding both, we have;
25/169 + 144/169 = 169/169 = 1
So this is also a point on the unit circle
Yes this is true since to covert cm to mm we have to multiply it by 10
Answer:
what you on about?
Step-by-step explanation:
Answer:
T=5.9235 seconds
Step-by-step explanation:
The time it takes for the cannonball to strike the ground is the point at which H(T)=0
This is a quadratic equation and since we have a bunch of decimals we use the quadratic formula:
a=-4,9, b=27.52, c=8.9
It takes 5.9235 seconds for the cannonball to strike the ground.
