The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.

<u>Explanation:</u>

We need to find the time at which the ball will be at height 19 feet.

Equation:

h = 3 + 34t - 16t²

19 = 3 + 34t - 16t²

16 = -16t² + 34t

-16t² + 34t - 16 = 0

On solving the equation, we get

t1 = 0.7 s and t2 = 1.42s

Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.

Reduce the fraction to lowest terms. y+5/2y+10<br><br>A:1/4<br>B:1/2<br>C:2/5
Oduvanchick [21]
The given fraction is:

\frac{y+5}{2y+10}

We cannot take anything common from the numerator but from the denominator we can take out 2 as common because 2 is a factor of both the terms i.e. 2y and 10. 

2y + 10 can be written as 2y +2(5) which can further be written as 2(y+5)

So, our fraction now becomes:

\frac{y+5}{2(y+5)}

y+5 occurs in both the numerator and denominator and thus be cancelled out leaving behind:

\frac{1}{2}

Therefore, the given fraction in lowest term is equal to 1/2. So option B is the correct answer

myrzilka [38]

Answer:

W(t) = 10 + 1.5*t

Step-by-step explanation:

Given:

The weight gain of the baby is 1.5 pounds per month.

After 4 months, baby's weight = 16 pounds

Let us the say the weight of the baby when it was born be x.

Then:

x + 1.5*(4) = 16

x = 10

Then weight of the baby as a function of number of months(t) will be=

initial weight + incremental weight per month*no of months(t).

W(t) = 10 + 1.5*t
