If the ball hit the ground it means that its height is equal to 0. In order to find the time after the ball <span>will hit the ground, we need to find the solution of the equation h(x)=0 which is different to 0.
-4.9x^2+21.3x=0
x(-4.9x+21.3)=0
-4.9x+21.3=0
x=21.3/4.9 = 4.3469 seconds</span>
Answer:
C. (1/2)acsinA
Step-by-step explanation:
Given is that, A, B, and C are the measures of the angles of a triangle and a, b, and c are the lengths of the sides opposite the corresponding angles.
So, the expression that does not represent the area of the triangle is :
C. (1/2)acsinA
The steps are more or less the same, except for one new addition:
1.Divide the tens column dividend by the divisor.
2.Multiply the divisor by the quotient in the tens place column.
3.Subtract the product from the divisor.
4.Bring down the dividend in the ones column and repeat.
The only rational root is -2.336071261738453
The other roots are complex (imaginary).
