Answer:
A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
Step-by-step explanation:
x = 3 + t
y = t² − 4
Eliminating the parameter:
t = x − 3
y = (x − 3)² − 4
This is an upwards parabola with a vertex at (3, -4).
x = 3 + t, so as t increases, x increases.
So the curve is traced from left to right.

Omar has a gift card with a $150 balance he buys several video games that cost $35 each after the purchase has his gift card balance is $45
Answer:
3
Step-by-step explanation:
150-35=115
115-35=80
80-35=45
Answer:
Omar bought 3 games? (You didn't ask a question but this is what I assumed)
Step-by-step explanation:
Use this equation to find out how many games (x) Omar bought with $45 left over.
45 = 150 - 35x
Combine like terms and put them on opposite sides of the equal sign.
-105 = -35x
Divide both side by -35
3 = x, so x = 3
Omar bought 3 video games

What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?
(6, 31)
(−6, 31)
(6, −31)
(−6, −31)
Answer:
This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]
Step-by-step explanation:
To find the x-coordinate of the vertex of a quadratic function, we can use the formula:
[tex]x=\frac{-b}{2a}[/tex]
We are given the function [tex]f(x)=x^2-12x+5[/tex]
In this function, [tex]a=1[/tex] and [tex]b=-12[/tex]
Now we can input these values into our formula
[tex]x=\frac{-(-12)}{2(1)} \\\\x=\frac{12}{2} \\\\x=6[/tex]
This means that the x-value of the vertex is located at [tex]x=6[/tex]. To find the other half of the coordinate pair, we can now plug [tex]x=6[/tex] into the given function
[tex]f(6)=(6)^2-12(6)+5\\\\f(6)=36-72+5\\\\f(6)=41-72\\\\f(6)=-31[/tex]
This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]
Which equation can be used to find the surface area of the cylinder?
r= 6 cm
h = 8 cm
S= 28(8)2 +2 (12)(6)
O S=2(6)? +2(6)(8) *
O S=212)2 + 23412)(8)
S = 2846)2 +27(6)(8)
Answer:
S = 2π(36) + 2π(6)(8)
S = 2(3.14)(36) + 2(3.14)(6)(8)
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of the base and the lateral area. A cylinder has 2 circular base .
Surface area = 2πr² + 2πrh
surface area = 2πr(r + h)
where
r = radius
h = height
surface area = 2πr(r + h)
r = 6 cm
h = 8 cm
The equation to find the surface area is represented below.
Surface area = 2πr² + 2πrh
S = 2π (6²) + 2π (6)(8)
S = 2π(36) + 2π (6)(8)
Assuming π is given as 3.14 the equation will be as follows
S = 2(3.14)(36) + 2(3.14)(6)(8)
onw of the factors of the polynomial x^3+5x^2+6x is (x^2 +3x)

One of the five cards is chosen at random. Find the probability of choosing a card with a number that
is a six. Write answer as a simplified fraction number, No decimals or percents:
Answer:
Zero.Step-by-step explanation:
Well, assuming that the cards are numbered 1, 2, 3, 4 and 5, then the probability of getting 6 is zero, because there's no card with such number.
Remember that a simple probability is a ratio between the possible events and the total number of outcomes. In this case, the total number of outcomes is 5 and the events are zero, because there's no card with 6.
Simplify the expression.

. Write the equation of a line in the graph below.
A. y = 3x - 2
B. y = 3x + 2
C. y = -3x - 2
D. y = -3x + 2
Answer:
D
Step-by-step explanation:
The y intercept is (0,2) so you can eliminate A and C because they have -2 and the slope is negative so you can eliminate B because it has a slope of +3 so you are left with D.
What is the slope of a line parallel to the line whose equation is x+y=5 Fully reduce your answer.
Slopes of Parallel/Perpendicular Lines
Answer:
-1
Step-by-step explanation:
y=-x+5
Parallel lines have same slopes.
The slope of the parallel and perpendicular lines will be -1 and 1, respectively.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given below.
x + y = 5
y = -x + 5
The slope of the equation is a negative one.
The slope of the parallel lines will be the same which is negative 1.
The slope of the perpendicular lines will be the negative inverse of the slope that is 1.
