Answer:
0.72 is the same as 72100 (try putting both into a calculator!) as you can view 1.00 as 11 . Reducing the fraction gives you 72100 = 1825 .
Answer:
A counterclockwise rotation of 270º about the origin is equivalent to a clockwise rotation of 90º about the origin. Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.
Hope it helped u if yes mark me BRAINLIEST... Plz. Plz plz!

Answer:
Equation of this line is y = 1
Step-by-step explanation:
We have to write an equation of a line passing through (0,1) and slope 0.
Standard equation of a line in slope form is y = mx + c
Where m = slope and c = y intercept.
Since m = 0
so y = c is the equation.
This line passes through (0,1)
so equation will be Y = 1
Equation of this line is y = 1
ANSWER
C.

EXPLANATION
The given function has range:
-3≤f(t)≤3
This implies that, the amplitude is

The function is symmetric with respect to the origin so this is a sine function.
This function is again reflected in the x-axis, hence
a=-3.
The period of this function is

This implies that, b=3,
hence the equation of the function is
