Answer:
B) 7/9
Step-by-step explanation:
<h3>Fraction addition:</h3>
- If the denominators are not same, find the LCM of the denominators.
LCM of 3 and 9 is 9.
- Now, find equivalent fractions with denominator as 9.

Answer:
Y = -24
Step-by-step explanation:
For this problem, evaluate simply means for each x, replace the value with -2. So, let's do that.
Y = 6*2x
Y = 6*2(-2)
Y = 6*-4
Y= -24

Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds
