A ball is thrown from an initial height of 3 meters with an initial upward velocity of 30 m/s. The ball's height h (in meters) a
yanalaym [24]

h=3+30t-5t^2\implies 13=3+30t-5t^2\implies 0=-10+30t-5t^2 \\\\\\ 5t^2-30t+10=0\implies 5(t^2-6t+2)=0\implies t^2-6t+2=0

now, it doesn't give us nice looking integers, so let's plug that into the quadratic formula.

~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{1}t^2\stackrel{\stackrel{b}{\downarrow }}{-6}t\stackrel{\stackrel{c}{\downarrow }}{+2}=0 ~\hspace{10em} t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ t= \cfrac{ - (-6) \pm \sqrt { (-6)^2 -4(1)(2)}}{2(1)}\implies t=\cfrac{6\pm\sqrt{36-8}}{2}

t=\cfrac{6\pm\sqrt{28}}{2}\implies t=\cfrac{6\pm\sqrt{2^2\cdot 7}}{2}\implies t=\cfrac{6\pm 2\sqrt{7}}{2}\implies t=\cfrac{2(3\pm 1\sqrt{7})}{2} \\\\\\ t=3\pm \sqrt{7}\implies t= \begin{cases} 3+\sqrt{7}\\ 3-\sqrt{7} \end{cases}\implies t\approx \begin{cases} 5.65\\ 0.35 \end{cases}

(01.01 MC)Which number line shows the solution to 5 + (−5)?
lesya [120]

The answer is the last one, because 5 + (-5) is the same as 5 - 5, which equals 0, which is what the arrow points to in the last one. :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

A doctor administers a drug to a 37
Aleks04 [339]

Answer:

Step-by-step explanation:

Daily dosage is 53 mg/kg(37 kg) = 1,961 mg

There are 24/4 = 6 four hour periods in each day.

So a four hour dosage should be 1961 / 6 =  327 mg

500 mg > 327 mg

So one tablet every 4 hours would exceed the recommended dosage by roughly 50%.

A closer dosage might be to take 1 tablet every 6 hours.

The suspension may be a better solution if effects of overdose are severe. A 5 mL dose every four hours would be very close to ideal.

Find all values of w for which the expression is undefined.
Reika [66]

Hello from MrBillDoesMath!

Answer:

 w = 8, -2



Discussion:

The expression is undefined when the denominator is zero. So when does

w^2 - 6w - 16 = 0?  Let's factor the expression. A little trial and error shows that 8 + (-2) = 6 (the coefficient of w) and 8 * (-2) = -16  (the constant value) so w^2 - 6w -1 6 = (w-8) (w- (-2))  and the expression equals zero when  w = 8 or w = -2


Thank you,

MrB
