Matteo is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satellite can be modeled by y^2=6x where x and y are modeled in inches. He realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite? (–1.5, 0) (0, –1.5) (0, 1.5) (1.5, 0)
Answer: (1.5, 0)
Step-by-step explanation:
Given : The shape of his satellite can be modeled by [tex]y^2=6x[/tex] where x and y are modeled in inches.
Now,the given equation [tex]y^2=6x[/tex] is a equation of parabola.
Here, coefficient of x is positive, hence the parabola opens rightwards.
On comparing this equation with standard equation [tex]x^2=4mx[/tex], we get
[tex]4m=6\\\Rightarrow\ m=\frac{6}{4}=1.5[/tex]
In standard equation, coordinates of focus=(m,0)
Thus for given equation coordinates of focus=(1.5,0)

What is the rate of change for the relationship represented in the graph? (1 point)
A. 1/15
B.1/14
C.14
D.15
The rate of change for the relationship represented in the graph is 15
What is rate of change?The rate of change of a linear graph is the slope of the graph
From the graph, we have the following ordered pairs
(x,y) = (0,0) and (2,30)
So, the rate of change (m) is then calculated as:
[tex]m =\frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]m =\frac{30 - 0}{2 - 0}[/tex]
Evaluate the differences
[tex]m =\frac{30 }{2 }[/tex]
Evaluate the difference
[tex]m=15[/tex]
Hence, the rate of change is 15

The Shake Shack sells large and small shakes. A large shake costs $5, and a small shake costs $3. On Sunday, the Shake Shack had a total revenue of $479. Which equation can be used to represent x, the number of small shakes sold and y, the number of large shakes sold?
479x + 479y = 15
4x + 4y = 479
5x + 3y = 479
3x + 5y = 479
Answer:
3x + 5y = 479
Step-by-step explanation:
As the problem states it, the number of small shakes will be represented by "x" and the number of large shakes will be represented by "y", so we know that the number of each mutiplied by the cost, its equal to the total revenue which is $479, so we just put that into an equation:
3x + 5y=$479
And that´s the equation that can be used to represent that inequality.
What is rhe name of the period that has the digits 751
The name of period that has 751 in the number
is hundreds.
Because Period is considered to a group of places of the
digits.
In this case, the given number is 751 and it is the group of hundred because 700 is the highest number it contains.
We can also write 751 as
751 = 700 + 50 + 1
It means,
