For each time period, each time "t" increases by one, the population will be multiplied by 4.
Answer:
A and A
the equation of a parabola in vertex form is
y = a(x - h)² + k
where ( h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x + 3)² + 2 is in this form
with vertex = ( - 3, 2)
To find the y-intercept let x = 0
y = - 2(3)² + 2 = - 18 + 2 = - 16
Similarly
y = - 2(x + 2)² + 2 is in vertex form
vertex = ( - 2 , 2)
x = 0 : y = - 2(2)² + 2 = - 8 + 2 = - 6 ← y- intercept
hope this helped
The expression for the number of sixth graders in terms of x is
<h3><u>Solution:</u></h3>
Given that , of the students in school are in sixth grade
To find: Expression for number of sixth graders
Let the total number of students in school be "x"
From given statement,
of the students in school are in sixth grade
Which means, of total number of students are in sixth grade
Let "n" be the number of students in sixth grade
Then by given statement,
n = of total number of students
Thus the expression in terms of x is found
