Answer:
C) Exponential Growth
Step-by-step explanation:
The geometric sequence is of the form a(n) = a*r^(n-1). For example, a(n) = 2*3^(n-1) with a = 2 as the starting term and r = 3 as the common ratio.
The variable n is in the exponent. We can replace it with x to get y = 2*3^(x-1); which graphs out to an exponential curve going uphill as you read it from left to right. This shows exponential growth, which matches with the growth of the original geometric sequence.
Answer:
I haven't done this in a while but I'm pretty sure it's C.
Step-by-step explanation:
A triangle has to have 180 degrees. angle a and c are congruent. angle b is slightly smaller. therofore, istead of all the angles biegh 60, a and c are 65 thus leaving angle b 50 degrees
You cannot divide by zero, because that is undefined, it approaches infinity, which is not a real value. Some would say that division by zero is "not allowed" :P
So in this case the divisor cannot equal zero.
x^2+4x+3=0 There are many methods to factor, I'll complete the square, just for conciseness (and it is good to know how the quadratic formula is derived)
Divide by the leading coefficient, which is just 1 in this case...
Move the constant to the other side, subtract 3 from both sides
x^2+4x=-3 Halve the linear coefficient, square it, then add that value to both sides...(4/2)^2=2^2=4
x^2+4x+4=1 Now the left side is a perfect square...
(x+2)^2=1 Take the square root of both sides
x+2=±√1 subtract 2 from both sides
x=-2±√1
x=-2±1
x=-3 and -1
So if the equation equals zero when x=-3 and -1, it's factors are:
(x+3)(x+1)
So x cannot equal -3 or -1, otherwise your original equation would have division by zero.
