6 dollars
Step-by-step explanation:
15-6=9
9-3=6
This is the concept of application of quadratic expressions. Given that the height of the ball is modeled by the equation;
h=-7.3t^2+8.25t+2.1+5
The time taken for the ball to hit the ground will be given as falls;
-7.3t^2+8.25t+7.1=0
to solve for t we use the quadratic formula;
t=[-b+/-sqrt(b^2-4ac)]/(2a)
a=-7.3, b=8.25, c=2.1
t=[-8.25+/-sqrt[8.25^2+4*7.3*7.1]/(-2*7.3)
t= -0.572
or
t=1.702
since there is not negative time we take the time taken for the ball to hit the ground will be: t=1.702 sec
Answer:
<em>the third one answer choice</em>
Step-by-step explanation:
<u><em>⊕ Place the triangle on a coordinate grid such that vertex A is at the origin, and segment AC lies on the x-axis.</em></u>
You will be able to see the length of segment AC and length of segment DE, and also will be able to see if AC║DE.
