f(t) =  -16t^{2} +48t + 100
Average rate of change from t = 3 seconds to t = 5 seconds = \frac{f(5)-f(3)}{5-3} =  \frac{(-16( 5^{2})+48(5)+100)-(-16( 3^{2})+48(3)+100  }{2}=\frac{(-16(25)+240+100)-(-16(9)+144+100)}{2} = \frac{(-400+240+100)-(-144+144+100)}{2}= \frac{-60-100}{2} = \frac{-160}{2} = -80

For every 1 litre of water used to make a medicine, 193ml of sucrose and 61ml of saline solution are used. Express the amount of
Brilliant_brown [7]
<h3>Answer is the ratio 1000:193:61</h3>

Explanation

1 liter = 1000 mL

For every 1000 mL of water, we need 193 mL of sucrose and 61 mL of saline solution.

The ratio is therefore 1000:193:61

We cannot simplify this ratio any further because the GCF of those three terms is 1.

A quick way to see this is to look at how 1000 = (2*5)^3 has prime factors 2 and 5, but 2 nor 5 are factors of 193 and 61. So only 1 is a factor of all three values 1000, 193, 61

For his long distance phone service, Keith pays a $3 monthly fee plus 11 cents per minute. Last month, Keith's long distance bil
____ [38]

Step-by-step explanation:

First, subtract 3 from 13.67 so we can find out the minutes only and not the minutes along with the monthly bill.

This will come out to be 10.67

Now, we will divide 10.67 by .11

          This will come out to be 97.

This means he was billed for 97 minutes on the phone

Hope I helped!

Please tell me if this is wrong and my most sincere apologies if it is.
