Answer:
the value of hi changes from 58 to 0:
h(t) = -4.9t^2 +19.8t
Step-by-step explanation:
If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.
Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
Answer:
x = -10
Step-by-step explanation:
6 • (x - 2) - (8x + 8) = 0
Pulling out like terms :
3.1 Pull out like factors :
-2x - 20 = -2 • (x + 10)
Equation at the end of step 3 :
-2 • (x + 10) = 0
Equations which are never true :
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x+10 = 0
Subtract 10 from both sides of the equation :
x = -10
One solution was found :
x = -10

Answer:
Step-by-step explanation:
The given triangle is a right angle triangle .
The known sides of the triangle that is opposite to angle y is 8 units while the side adjacent is 10 units.
The value of y can be calculated using the tangent ratio.
We solve for y to get,
We evaluate to obtain,
to the nearest degree
