Answer:
time taken = 2.74 seconds
Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground
We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t²
110 = 16t²
t² = 110/16
t² = 6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative
Hope this helps :)
Answer: 14.7 grams
Step-by-step explanation:
Given : Henry has two pixie sticks full of delicious sugar.
Each pixie stick has 22 grams of sugary goodness.
Then, Total sugary goodness in 2 pixie sticks= 
Total persons = 3 [Including himself]
If he divides 2 sticks evenly among 3 persons , then the amount of sugary goodness each persons will receive
= Total sugary goodness in 2 pixie sticks divided by 3
grams
Hence, He will share 14.7 grams of sugary goodness with each of his friends.
Answer:
2p² + 14p + 2
Step-by-step explanation:
Given that;
C= 1+p²+3p
B=2p+6p
The expression that equals to : 2C - -B will be;
2{1+p²+3p} - {-2p-6p}
2+2p²+6p + 2p + 6p
2p² + 6p +2p +6p +2
2p² + 14p + 2
The first question answer is 21*10^7
The second question answer is 5*10^2
