Answer:
Vertex Form: y= 2(x−1)^2−7
Step-by-step explanation:
I believe this is correct
It is positive and increasing
Answer:3, 25
Step-by-step explanation:
The seconds should be the x-axis and the height is y axis. Also thinking about how a kicked ball makes an arch, the max is 25, and the mid point between 0 and 6 is 3.
140°
Pentagons add up to 540° so if you add all the degrees you get 400° and if subtracted from 540° you get 140°
Answer:
θ = 83°
Step-by-step explanation:
For acute angles, the sine of an angle is the cosine of its complement, and vice versa.
__
sin(θ) = cos(90° -θ) . . . . relation between sine and cosine
sin(θ) = cos(7°) . . . . . . . . given
90° -θ = 7° . . . . . . . . . matching arguments of cos( )
θ = 83° . . . . . . . . . add θ -7° to both sides
