Answer: 4/15
Step-by-step explanation:
-1/3 - -3/5
Two negative signs become positive so it's
-1/3+3/5
Taking the LCM as 15,
-1/3= -5/15
3/5= 9/15
-5/15 + 9/15
= (-5+9)/15
= (9-5)/15 ( just changing the order without changing the sign)
= 4/15
This is the simplest form
(If you need it in decimal form is 0.26666... or 0.267)

The time it will take the pebble to reach the maximum height is 1.5secs
Given the quadratic equation that models the path of the pebble expressed as p(t) = –16t^2 + 48t + 110
We can calculate the time taken by the pebble to reach the maximum height.
At maximum height, the velocity of the pebble is zero i.e. p'(t) = 0
p'(t) = -32t + 48
0 = -32t + 48
32t = 48
t = 48/32
t = 1.5secs
Hence the time it will take the pebble to reach the maximum height is 1.5secs

Answer:
Friday is the hottest, and Thursday was the coolest so here it is.. 75.5,75.45, and 75.05
Step-by-step explanation:
Just look at the temperatures and the 5 is larger than the .45 because its basically a "4.5". :)
Answer is x+2 is a factor of numerator
x^2+4x+4= a^2+2ab+b^2=(a+b)^2
(x)^2+2(x)(2)+(2)^2=(x+2)^2
