defon

Answer:

$3 \: s$

Step-by-step explanation:

$y = - 16 {x}^{2} + 32x + 48 \\ 0 = \frac{ - 16 {x}^{2} + 32x + 48 }{ - 16} \\0 = {x}^{2} - 2x - 3 \\ 0= {x}^{2} - 3x + x - 3 \\ 0= x(x - 3) + 1(x - 3) \\0 = (x + 1)(x - 3) \\ \\ x + 1 = 0 \\ x = - 1 \\ x - 3 = 0 \\ x = 3$

Hope this helps you.

Lorico [155]

Answer:

Please see the answers below:

Step-by-step explanation:

The wrong answers are deleted only the correct answers are listed below:

Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.

Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.

Claire saves $320 in 16 weeks. The unit rate is $20 per week.

% increase in price of gas = [(New Price - Original Price) / Original Price] x 100

% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100

% increase in price of gas = [$0.3 / $2.18] x 100

% increase in price of gas = 13.76%

A cohort study was conducted to study the association of coffee drinking and anxiety in a population-based sample of adults. Amo

azamat

Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.

Step-by-step explanation:

Since we have given that

Number of coffee drinkers = 10000

Number of whom developed anxiety = 500

Number of non coffee drinkers = 20000

Number of whom developed anxiety = 200

So, probability of getting anxiety from coffee drinkers = $\dfrac{500}{10000}=0.05$

Probability of getting anxiety from non coffee drinkers = $\dfrac{200}{20000}=0.01$

so, Relative risk of anxiety associated with coffee use is given by

$\dfrac{0.05}{0.01}=5$

Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
