Which is the equation of a parabola with vertex (0,0), that opens to the right and has a focal width of 8?

Answers

Answer:

Equation of parabola:

y^2=8x

Step-by-step explanation:

A parabola with vertex (0,0), that opens to the right.

The general equation of parabola open right whose vertex (0,0)

y^2=4px

Focal width : Two points opposite to the the focus on parabola.

Distance between these two points is called focal width i,e 4p

Focal width = 8

So, 4p=8

p=2

Focus: (2,0)

Equation of parabola:

y^2=8x

Answer:

Vertex: V=(0,0)=(h,k)→h=0, k=0

Opens downward:

(x-h)^2=4p(y-k)

Width focal: p=-6<0 (donwnward)


Replacing h=0, k=0 and p=-6 in the equation above:

(x-0)^2=4(-6)(y-0)

x^2=-24y


Answer: The equation of the parabola is  x^2=-24y

Trail mix cost $5.76 for 8 ounces. What is the cost per ounce ?

Answers

I believe it is 1.38
Answer is 0.72 cents. You would need to divide $5.76 by 8 which equals 72 cents. To check it just multiply 0.72 by 8 and that will give you $5.76.

The equation shows the relationship between x and y:y = 7x + 2

What is the slope of the equation?


-7
-5
2
7

Answers

y=mx+b is the formula.
m is the slope and b is the y-intercept.

y-intercept is when x is 0 and x-intercept is when y is 0. So if x is 0, y=m(0)+b which is y=b. So on the graph y will be b when x is 0.

So in y=7x+2, 7 is the slope and 2 is the y-intercept.

\sf\ Slope:\ {\boxed{7}


y={\underbrace{m}x+{\underbrace{b}
\sf\~~~~SLOPE~~~~~Y-INTERCEPT

Below is the slope intercept form:
y = mx + b

where: m = slope; b = y-intercept.

Using the above format, 

y = 7x + 2

m = 7 ; b = 2

The slope of the equation is 7.
The y-intercept of the equation is 2.

first one 776 becasue you do half of 36 and then do to the cube and do 4/3
2) B because you need to to 5^3 then do 4/3 and multiply by 3.14
3)2350.87 because 8.25 ^ 3 then times 4/3 and multiplpy by 3.14
