Answer:
4 seconds to reach 200 feet
Step-by-step explanation:
You can use Desmos (graphing calculator) then plug in the equation and you will find the x-values are 7.188 and 0- the origin.
Divide 7.188 by 2 (this is also solving for the midpoint/axis of symmetry) and you get 3.594
Round 3.594 to the nearest second which would be 4 seconds.
Hope that helps and have a great day!
First let us find
Now let;s solve the second part
Answer: by combining 1/4 and 1/3 and then you find the amount of left over dog food. Multiply the fractions so they have common denominators, then add. You will get 3/12 + 4/12 = 7/12. 12 - 7 = 5, so there is 5/12 of the bag left.
Step-by-step explanation:
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2
