Answer:
2.5 • 10^6
Explanation:
In order for 25 • 10^6 to be written in standard form, the ‘25’ needs to be less than 10. To do that we will move the decimal one place to the left so that 25 is now 2.5; it is now a number less than 10. It should now look like 2.5 • 10^6. It is now in standard form.
So first you need to factor and get 8( t-1 ) (2t+1)=0. Then you need to divide both sides by 8 to isolate the equation. 0/8=0 so ( t-1 ) (2t+1)=0. Next set each of the factors = to 0 and get t-1=0 and 2t+1=0. Solve, and get t=1 and t=-1/2. The negative does not apply so you know it takes 1 second for the ball to hit the ground.

Step-by-step explanation:
Answer:
72°
Step-by-step explanation:
the top angle in the triangle=36° because alternate angles are equal
the triangle is an isosceles triangle hence the base angles are equal
the sum of angles in a triangle is 180°
180°=(36+i°+i°)
180=36+2i°
2i°=180-36
2i°=144
i°=144/2
i°=72°
