Answer:
20 movies
Step-by-step explanation:
x = number of movies
(75 + 2x) = 5.75x
2x = 5.75x - 75
3.75x = 75
x = 20

Use the Graph of the parabola to fill in the table
Answer:
a) Upwards
b) x = -1
c) (-1,-9)
d) x intercepts; (2,0) and (-4,0)
y intercept is (0,-8)
Step-by-step explanation:
a) As we can see, the parabola faces upwards
b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts
The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry
c) The vertex represents the lowest point of the circle here,
As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola
We have the coordinates of this point as
(-1,-9)
d) The intercepts
The x-intercept are the two points in which the parabola crosses the x-axis
We have this point as 2 and -4
The x-intercepts are at the points (2,0) and (-4,0)
For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)
Find the 1st 4 iterations if f(o)= -2, f(n)= 3f(n-1)-2n
Answer:
Step-by-step explanation:
f(0) = -2
f(1) = 3*(f(1 - 1)) - 2*1
f(1) = 3(-2) - 2
f(1) = - 6 - 2
f(1) = - 8
f(2) = 3*(f(1)) - 2*2
f(2) = 3*(-8) - 4
f(2) = -24 - 4
f(2) = - 28
f(3) = 3*(f(2)) - 2*3
f(3) = 3*-28 - 6
f(3) = -84-6
f(3) = - 90
f(4) = 3*f(3) - 2 * 4
f(4) = 3*-90 - 8
f(4) = -270 - 8
f(4) = -278

Which equation best represents the relationship between x and y in the table below?
Answer:
y = x² + 5
Step-by-step explanation:
When x = 1:
y = x² + 5
y = 1² + 5
y = 6
When x = 2:
y = x² + 5
y = 2² + 5
y = 9
When x = 3:
y = x² + 5
y = 3² + 5
y = 14

What point of the number line represents the sum of 3/4 + 3/4
Answer:
C
Step-by-step explanation:
3/4+3/4=6/4=1 2/4=1 1/2
C is located halfway between 1 and 2, so you know it is 1 1/2.
A fraction is a way to describe a part of a whole. The number on the number line is represented by point C.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
To plot the fraction on the number line, the sum of the number line is needed to be found. Therefore, the sum of the number line can be written as,
[tex]\rm Sum = \dfrac34 + \dfrac34 = \dfrac64[/tex]
Thus, the sum of the fraction is (6/4), which can also be written as 1.50.

Which temperature is colder -10 or 0
Answer:
-10
Step-by-step explanation:
A lake near the Arctic Circle is covered by a 222-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 333 weeks, the sheet is only 1.251.251, point, 25 meters thick.
Let yyy represent the ice sheet's thickness (in meters) after xxx weeks.
Complete the equation for the relationship between the thickness and number of weeks.
y=y=y, equals
Answer:The question is a little incorrect, the ice sheet thickness should be 2m and not 222m.
The required function formula is,
S(t) = 2 - 0.25 t
Step-by-step explanation:
Here, the initial thickness of the ice sheet = 2 meters,
After 3 weeks, the thickness of ice sheet = 1.25 meters
Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,
⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,
Since, the ice is melting with the constant rate.
⇒ The rate of ice decreasing = 0.25 meters per week.
⇒ Total changes in t weeks = 0.25 t meters
The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.
⇒ S(t) = 2 - 0.25 t
Which is the required function's formula.

Which expression is equivalent to 18 − 20?
Alberto invests $4,571 in a retirement account with a fixed annual interest rate of 3% compounded 6 times per year. What will the account balance be after 18 years?
A) $7,833.32
B) $7,162.06
C) $7,602.38
D) $6,985.59
Answer:
A) $7,833.32
Step-by-step explanation:
Given data
Principal= $4,571
Rate=3%
n= 6
Time = 18 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.005)^6*18
A= 4571(1.005)^6*18
A= 4571(1.005)^108
A=4571*1.7136
A=$7832.86
Hence the approximate amount is A) $7,833.32
Find the fifth term and the nth term of the geometric sequence whose initial term, a, and common ratio, r, are given. a = 3 ; r = 5
Answer: 1875
Step-by-step explanation:
The nth term of a geometric progression is given as:
= ar^n-1
Given a = 3 ; r = 5, the nth term will be:
= ar^n-1
= 3 × 5^n-1
The fifth term will be:
= 3 × 5^n-1
= 3 × 5^5-1
= 3 × 5⁴
= 3 × 625
= 1875
The fifth term is 1875

Is the ordered pair (-5, 4 a solution of
the system of linear equations whose
graph is shown? Explain your reasoning.
Answer:
No
Step-by-step explanation:
No, (-5, -4) is not a solution to the system of equations. In order for a point to be a solution to a system of equations, the lines have to intersect at that point in a graph. Looking at the given graph, the lines do not intersect at (-5, -4), but at (-4, -5) instead. Thus, (-5, -4) is not a solution.
