Answer:
(2) sqrt( 2d /a) =t
Step-by-step explanation:
d = 1/2 a t^2
Multiply each side by 2
2d = 2*1/2 a t^2
2d = a t^2
Divide each side by a
2d/a = a t^2 / a
2d /a = t^2
Take the square root of each side
sqrt( 2d /a) = sqrt( t^2)
sqrt( 2d /a) =t
Answer:
C = 18.8 cm
Step-by-step explanation:
The diameter is 6 cm
To find the circumference, we use
C = pi*d
C = 3.14 *6
C =18.84 cm
Rounding to the nearest tenth
C = 18.8 cm
Answer:
A. 50º
Step-by-step explanation:
we are given the exterior angles 140º and 90º
exterior angles + corresponding interior angles = 180º
that means the two other angles of the triangle are:
180 - 140 = 40º
and
180 - 90 = 90º
the sum of interior angles in a triangle = 180
p = 180 - (40 + 90)
p = 180 - 130
p = 50º
