I will sit down, if there is an open chair.
Answer:
c
Step-by-step explanation:
The number 2.5 in this function represents the average number of people each person challenged. Then the correct option is D.
<h3>What is an exponent?</h3>
Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as
y = a(b)ˣ
The number of people participating in a challenge is an example of exponential growth and might be modeled by a function such as
y = 2 × (2.5)ˣ
The number 2.5 in this function represents the average number of people each person challenged.
Then the correct option is D.

Answer:
Remember that a perfect square trinomial can be factored into the form (a+b)^2
or (a-b)^2
Examples:
(x+2)(x+2) is a perfect sq trinomial --> x^2+4x+4
(x-3)(x-3) is a perfect sq trinomial --> x^2-6x+9
(x+2)(x-3) is not a perfect square trinomial because its not in the form (a+b)^2 or (a-b)^2
Now to answer your question,
for the first one, x^2-16x-64, you cannot factor it so it is not a perfect square trinomial
for the second one, 4x^2 + 12x + 9, you can factor that into (2x+3)(2x+3) = (2x+3)^2 so this is a perfect square trinomial
for the third one, x^2+20x+100 can be factored into (x+10)(x+10) so this is also a perfect square trinomial
for the fourth one, x^2+4x+16 cannot be factored so this is not a perfect square trinomial
Therefore, your answer is choices 2 and 3

Step-by-step explanation:
Hey there i can help ya !
check the slope between the moving points
slope between (–6, –1) & (–3, 2) = 1 slope between (-3, 2) & (–1, 4) = 1 slope between (-1, 4) & (2, 7) = 1
the points are collinear and make an angle of 45 degrees with the x-axis
we can have an equation of a line passing through (-6,-1) and slope 1 as
(y + 1) = 1(x + 6) y = x + 5 is your linear model mostly
