Find the equation of the parabola whose vertex is the origin and whose directrix is x = -4
Try this option:
1) if V(0;0) and x= -4, then common view of the required equiation is:
(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;
2) if the V(0;0), then h=k=0 and the required equiation is:
y²=4px;
3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:
y²= -16x
answer: y²= -16x
The distance between the points(-3, -5) and (2,7) on the coordinate plane is given as 5^2+ t^2. what us the value of t
Answer:
Step-by-step explanation:
so we can use [tex]t^{2}[/tex] + 25 as one expression and the find the distance between the points and set the expression equal to that number. That's our strategy.
dist = the square root of [tex]x^{2}[/tex] + [tex]y^{2}[/tex]
where x and y are the change in x2 to x1 and y2 to y1
P1 = ( -3, -5)
P2 = (2, 7 )
dist = square root of ( [2 -(-3) ]^2 + [7-(-5)]2)
dist = sq rt ( 5^2 + 12^2 )
dist = sq rt ( 25 + 144)
dist = sq rt (169)
dist = 13
now set our eq. equal to that number
[tex]t^{2}[/tex] + 25 = 13
[tex]t^{2}[/tex] = -12
this is looking kinda bad, do you know complex numbers?

Answer:
6i(9i)
Step-by-step explanation:
This table shows the cost of renting a kayak.
Hours Cost
1. $13
2. $21
3. $29
4. $37
5. $45
The cost of renting a kayak is represented by the equation
y = 8x + 5, where x represents the number of hours. What
does the slope of the equation represent?
9514 1404 393
Answer:
dollars per hour
Step-by-step explanation:
If m is the slope, the units of m can be found by considering the units of x and y.
y is in dollars
x is in hours
Then from the point of view of units, we have ...
dollars = m × hours
m = dollars/hours
The slope in the equation is the rental charge in dollars per hour.
Alex's times for running a mile are Normally distributed with a mean time of
5.28 minutes and a standard deviation of 0.38 seconds. Chris's times for
running a mile are Normally distributed with a mean time of 5.45 seconds
and a standard deviation of 0.2 seconds. Ten of Alex's times and 15 of Chris's
times are Tandomly selected. Let x Overbar Subscript Upper A Baseline
minus x Overbar Subscript Upper C represent the difference in the mean
times for Alex and Chris. Which of the following represents the shape of the
sampling distribution for x Overbar Subscript Upper A Baseline minus x
Overbar Subscript Upper C?
Answer: Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds. Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds. Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris. Which of the following represents the shape of the sampling distribution for x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C?
Normal, because both population distributions are Normal.
Uniform, because the both sample sizes are less than 30.
Skewed right, because the difference in times cannot be negative.
Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.
Step-by-step explanation: Can someone tell me the answer?
Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.
Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds.
Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds.
Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris.
What is the standard deviation?The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
Normal, because both population distributions are Normal.
Uniform, because both sample sizes are less than 30.
Skewed right, because the difference in times cannot be negative.
Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 25 feet more than the length of the shortest side. Find the dimensions if the perimeter is 157 feet
What is the length of the shortest side?
What is the length of the second side?
What is the length of the third side?
Answer:
shortest: 33 feet
second: 66 feet
third: 58 feet
Step-by-step explanation:
s = shortest side (33)
2s = second side (66)
25 + s = third side (58)
157 = s + 2s + 25 + s
157 = 4s + 25
4s = 132
s = 33

Step-by-step explanation:
to find the scale factor you take the coordinates of the image and divide it by the coordinates of the preimage
ex. A' coordinates are (3,1)
A coordinates are (6,2)
3/6=1/2
1/2=1/2
therefore the scale factor is 1/2

The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)+2.
Which statement about the graphs is true?
The vertex of the graph of g is 2 units above the vertex of the graph of f.
The vertex of the graph of g is 3 units to the right of the vertex of the graph of f.
The vertex of the graph of g is 2 units below the vertex of the graph of f.
The vertex of the graph of g is 2 units to the left of the vertex of the graph of f.
Answer:
The vertex of the graph of g is 2 units above the vertex of the graph of f.
Step-by-step explanation:
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.
Then the g(x) will be
g(x) = x² + 2
We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.
The graph is shown.
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).
Thus, the correct option is A.

A movie theatre charges adults $10 to see a movie and charges children $6. If there wereq 120 people who saw a movue and the theatre collected $928, home many attendees were adults
Answer:
The number of adults tickets sold equals 52.
Step-by-step explanation:
First, we need to establish the system of equations:
x= number of adults tickets sold
y= number of kids tickets sold
10x + 6y= 928
x + y=120
Now, we isolate x in one equation and change it in the other to obtain its value:
x= 120 - y
10(120 - y) + 6y = 928
1,200 - 10y + 6y = 928
272 = 4y
68 = y
x= 120 - 68= 52
