Tan=z/10 and cos=10/y from cos we know the hypotenuse is y. from tan we know the opposite side is z
So sinx=z/y

Explanation:
a) The velocity curve is linearly increasing from 0 to 6 m/s over a period of 2 seconds, then linearly decreasing from 6 m/s to 0 over the same period. The acceleration is the rate of change of velocity, so for the first half of the motion the acceleration is a constant (6 m/s)/(2 s) = 3 m/s². Similarly, over the second half of the motion, the acceleration is a constant (-6 m/s)/(2 s) = -3 m/s².
The distance traveled is the integral of the velocity, so the linearly increasing velocity will cause the distance vs. time curve to have a parabolic shape. The shape will likewise be parabolic, but with decreasing slope, as the velocity ramps down to zero. Overall, the distance versus time curve will have an "S" shape.
The motion (position and velocity) will be continuous, but the acceleration will not be. There will be a significant "j.erk" at the 2-second mark where acceleration abruptly changes from increasing the velocity to braking (decreasing the velocity).

b) The attachment shows the (given) velocity curve in meters per second and its integral, the position curve, in meters.
The integral in the attached works nicely for machine evaluation. For hand evaluation, it is perhaps best written piecewise:
![s(t)=\begin{cases}\displaystyle\int_0^t{3x}\,dx\qquad\text{for $x\le2$}\\\\\displaystyle6+\int_2^t{(12-3x)}\,dx\qquad\text{for $2](https://tex.z-dn.net/?f=s%28t%29%3D%5Cbegin%7Bcases%7D%5Cdisplaystyle%5Cint_0%5Et%7B3x%7D%5C%2Cdx%5Cqquad%5Ctext%7Bfor%20%24x%5Cle2%24%7D%5C%5C%5C%5C%5Cdisplaystyle6%2B%5Cint_2%5Et%7B%2812-3x%29%7D%5C%2Cdx%5Cqquad%5Ctext%7Bfor%20%242%3Cx%5Cle4%24%7D%5Cend%7Bcases%7D)
Hello!
![\frac{15}{4}=3](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B4%7D%3D3%20%3C----remainder)
Answer: ![=3\frac{3}{4}](https://tex.z-dn.net/?f=%3D3%5Cfrac%7B3%7D%7B4%7D)
Explanation: You can also take 3 from your answer and it becomes a whole number. Next take the remainder and make it the numerator. Then you keep from the denominator by the same thing. Hope this helps! Thank you for posting your question at here on Brainly. Have a great day! -Charlie
Ok sorry but I see someone is online can you help
With a science question
Answer:
Te diagonal of a kite will form a parallelogram.
explanation:
Kite properties include (1) two pairs of consecutive, congruent sides, (2) congruent non-vertex angles and (3) perpendicular diagonals. Other important polygon properties to be familiar with include trapezoid properties, parallelogram properties, rhombus properties, and rectangle and square properties.
hope it helps
