The value of p is (x22)(3x•21)
Answer: -11 degrees Celsius
Step-by-step explanation:
4:00 am = -16 degrees
You know that 4:00am is four hours after midnight and you know that the temperature decreases by 1.75 degrees every hour so during that time it has dropped by:
1.75x4=7 degrees
Because it is -16 at 4:00am, you know it was 7 degrees higher at midnight
-16+7=-11
It was -11 degrees at midnight
The nut lands first on gorund
<em><u>Solution:</u></em>
The squirrel climbs down the tree in 2 seconds
Given that,
A squirrel is 24 feet up in a tree and tosses a nut out of the tree with an initial velocity of 8 feet per second
<em><u>The nuts height, h, at time t seconds can be represented by the equation:</u></em>
time cannot be negative, so ignore t = -1
Thus the nut takes 1.5 seconds to reach ground
From given,
The squirrel climbs down the tree in 2 seconds
Therefore, the nut lands first on gorund
Answer:
(Opt.B) 18
Step-by-step explanation:
4x = 2y - x (vertically opposite angles are equal)
4x + x = 2y
5x = 2y ----- (1)
4x + 2y + x = 180 (Linear pair angles)
5x + 2y = 180
From (1) we can understand that, the value of 5x and 2y is the same. So,
5x + 5x = 180
10x = 180
x = 180/10
x = 18
Just completing,
Putting the value of x in (1)
5*18 = 2y
90 = 2y
90/2 = y
45 = y

The amount of Tritium that bottle contains now will be 439,421.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 - r)ˣ
Where x is the number of times this decay occurs, a = initial amount, and r = fraction by which this decay occurs.
Tritium is a radioactive isotope of hydrogen that rots by around 5% each year. An enormous container of water that contained 856,000 tritium iotas stayed undisturbed for a very long time.
Then the amount of Tritium that bottle contains now will be given as,
y = 856,000 (1 - 0.05)¹³
Simplify the equation, then we have
y = 856,000 (1 - 0.05)¹³
y = 856,000 (0.95)¹³
y = 856,000 (0.51334)
y = 439,421
The amount of Tritium that bottle contains now will be 439,421.
