Hi there!

I believe your answer is:
-15

Here’s why:
⸻⸻⸻⸻
- The temperature dropped from 15°F to 0°F.
- The change was negative in value since it dropped to a lower temperature.
- The temperature dropped by 15 degrees, so we would fill in the blank with -15.

Hope this helps you. I apologize if it’s incorrect.

The probability of one coin landing on heads is 50%. To get the probability of both landing on heads, you multiply .5 by .5, and you get 0.25, or 25%.
Answer:
A volcano ejected with an initial velocity of 304 feet per second.
The height in feet is given by the equation H=-16t^2+ 304t where t is the time in seconds.
We will use the equation that traces the path of the projectile to determine the following information:
1) The time it takes the projectile to reach its maximum height (using the vertex formula: t=-b/2a)
The equation; H = -16t^2 + 304t, a=-16; b=304
t = -304/2°(-16)
t = 9.5 sec to reach max height
2) The maximum height of the projectile (use the result from part 1 to find the maximum height of the projectile)
t = 9.5
H = -16(9.5^2) + 304(9.5)
h = = -1444 + 2888
h = 1444 ft is the max height
3) Find the time it takes the projectile to return to the ground. Assume that the projectile starts at height H=0.
-16t^2 + 304t = 0
factor out -16t
-16t(t - 19) = 0
t = 19 sec to reach the ground

Answer:
Second one and the fourth one.
Step-by-step explanation:
Let’s look at this. When we are finding the area of the rectangle, we multiply the length times the width. Let’s look at the first option.
2 times (x + 7)
2x + 14
this one won’t work.
second one:
14(x + 3)
14x + 42
this works.
thrid one.
14(x+5)
14x + 70
nope.
fourth one.
7(2x+6)
14x + 42
works.
fifth one,
2(7x +20)
14x + 40
Does not work.
