Answer: 8 posters
Step-by-step explanation:
From the question, we are informed that Lincoln has 16 pins in one box and 17 pins in another box and that he uses 4 pins to hang each posters posted. The total number of posters he can hang with the pins goes thus:
We should first calculate the total number of pins he has.
= 16 + 17 = 33 pins
Since he uses 4 pins to hang a poster, we then divide 33 pins by 4.
= 33 ÷ 4
= 8.25
This means that he can hang 8 posters with the pin
Answer: c. (3, 7)
Step-by-step explanation:
<span>h= (-16t^2 + 28t + 7) </span>
find the derivative to get time<span>
<span>
h' = (-32t + 28)
When the ball reaches its maximum height, its
vertical velocity (h’) will be 0 </span></span>
<span>
<span>
0 = -32t + 28 </span></span>
-32t=-28
<span><span>-28/-32 = </span>0.875
seconds </span><span>
<span>
The ball reaches its maximum height in 0.875
seconds after being thrown; plug and chug and:
h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>
Max height = 19.25 feet, time = 0.88 seconds
|-5| - |7 - 4|
First, simplify |-5| to 5. / Your problem should look like: 5 - |7 - 4|
Second, simplify 7 - 4 to 3. / Your problem should look like: 5 - |3|
Third, simplify. / Your problem should look like: 2
