Answer:
p*q
Step-by-step explanation:
(x + p)(x + q) = xx + px + qx + pq from binomial expansion
Hello!
To solve this you put 6 in for r
When you put this into a calculator you get the answer of 113.10
Hope this helps!
<h3>
Answer: 12pi millimeters</h3>
======================================================
Explanation:
The circumference of a circle is the distance around the full circle, aka the perimeter.
The formula for the circumference is
C = pi*d
where d is the diameter. The radius given is 6, so the diameter is 2*6 = 12.
The circumference, is therefore:
C = pi*d
C = pi*12
C = 12pi millimeters
---------
As a slight alternative, you can use this formula
C = 2*pi*r
with r = 6 as the radius
C = 2*pi*r
C = 2*pi*6
C = 2*6*pi
C = 12pi
We get the same answer as before.
Answer:
D
Step-by-step explanation:
÷
Keep, change, flip.
So, stays the same.
The division sign changes to multiplication.
changes to 5.
So now you have
×=
6·4=24
25-24=1

The initial temperature difference of 101-45 = 56 degees declined to 101-55 = 46 degrees in 8 minutes, We can write the exponential equation for the soda's temperature as
... T = 101 -56(46/56)^(t/8) . . . . where t is in minutes
After an additional 10 minutes, we have t=18, so the soda temperature will be
... T = 101 -56(46/56)^(18/8) ≈ 65.0 . . . degrees
