Answer:
* = b²
Step-by-step explanation:
You know that the square of a binomial is of the form ...
(x + y)² = x² + 2xy + y²
Matching given terms, we have ...
49 = y²
2xy = 14b
Solving the first of these relations for y, we have
y = √49 = 7
Putting that in the second relation and solving for x, we find ...
2x·7 = 14b
14x = 14b
x = b
Then the first term of the expansion, x², will be b².
The missing term is b².
Answer:
BC = 9 miles
Step-by-step explanation:
Here, we are given ΔABC ∼ ΔEDC, which means both triangles are similar and they tend to have the same dimensions and properties.
To find the length of BC, we are given the proportion:

Where x represents the length BC.
Solving further, let's cross multiply


Solving for x, we have:

Lets divide both sides by 8


Therefore the distance BC is 9 miles

Step-by-step explanation:
Newton's Law of Cooling:

Temperature given at a time
Time
Surrounding temperature
Initial temperature
Constant (Euler's number) ≈ 2.72
Constant
Using this information, find the value of
, to the nearest thousandth, then use the resulting equation to determine the temperature of the water cup after 4 minutes.
First, plug in the given values in the equation and solve for
:
197°,
1.5 minutes,
70° and
210°

≈ 
Let the temperature of the water cup after
minutes be 
Now, let's plug the new time and
constant in the equation and solve for
:




![x=70+{\frac{140}{\sqrt[50]{e^{13}}}\\](https://tex.z-dn.net/?f=x%3D70%2B%7B%5Cfrac%7B140%7D%7B%5Csqrt%5B50%5D%7Be%5E%7B13%7D%7D%7D%5C%5C)

≈ 
Temperature of water after 4 minutes is 178°
