Answer:
Step-by-step explanation:
The slope of the graph at x=0 is related to the value of b. It is also proportional to the value of <em>a</em>, which is the same for all but curve B. The red curve R has the largest slope at x=0, (much larger than 3/4 the slope of curve B), so curve R has the greatest value of <em>b</em>.
Similarly, the smallest value of <em>b</em> will correspond to the curve with the smallest (most negative) slope. That would be curve K. Curve K has the smallest value of <em>b</em>.
circumference is actually a closed boundary of a curved geometric figure like circle.
it can be calculated by applying the formula C = π * d ( d= diameter)
or C = 2πr ( r= radius)
you can use any one to find out the circumference of the circle.
But from your attached document,it is clear that circumference is given, sorry, I don't understand for what you are looking for?
diameter goes straight through the center of a circle and touches the boundaries of the circle in both sides.
Diameter is always double of radius, D = 2r ( r= radius)
or you can find radius by dividing it by 2,
r = D/2
I hope it will serve your purpose.
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.
There are two possible solutions
X=3
X=-3
