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:
0
Step-by-step explanation:
→ Find the change in y coordinates
-6 --6 = 0
→ As the change in y is 0, the gradient is 0
Answer:
<em>2⋅(2x+1)</em>
<em></em>
<em>Step-by-step explanation:</em>
(12x + 4 • (3 - 2x)) - 10
<em>Pull out like factors :</em>
4x + 2 = 2 • (2x + 1)
<em>Final result :</em>
2 • (2x + 1)

Answer:
For any exponential function in which the base is less than 1, it will be an exponential decay situation. In this problem, the base is 0.97. The amount that the base is less than 1 ( i.e. 1 - base) represents, in decimal form, the percent of decrease, which in this case is 0.03 or 3%.
Step-by-step explanation:
The formula for exponential decay is y=a(1-r)x.
r is the decay rate.
