What are the focus and the directrix of the graph of x=1/24 y^2

vladimir2022 [97]

The given equation of parabola is:

$x= \frac{1}{24} y^{2}$

Part 1) Focus of the Parabola

In order to find the focus and equation of directrix, we first have to convert the given equation to standard form of parabola.

$24x= y^{2} \\ \\ 
4*6(x)= y^{2} \\ \\ 
(y-0)^{2} =4*6*(x-0)$

The focus of the general equation of parabola shown below lies at (h+p, k)
$(y-k)^{2}=4p(x-h)$

Comparing our equation to the general equation we get:
h=0
k=0
p=6

So the focus of given parabola will be (0+6, 0) = (6,0)

Part 2) Directix of the Parabola

The directrix of the general parabola shown above lies at:

x = h - p
Using the values of h and p, we get

x = 0 - 6

x = -6

So, the directrix of the given parabola has the equation x = -6

The double number lines show the ratio of yards to miles. A double number line with 6 equally spaced tick marks. The line labele

tia_tia [17]

There will be 781440 yards in 444 miles.

Given, The double number lines show the ratio of yards to miles.

A double number line with 6 equally spaced tick marks.

The line labeled yards, reads from left to right: 0, four unlabeled tick marks, 8,800. The line labeled miles, reads from left to right: 0, four unlabeled tick marks, 5.

as, 1 mile = 1760 yards

we have to find the number of yards in 444 miles.

if 1 mile = 1760 yards

on multiplying both the sides by 444, we get

444 miles = 1760 × 444

444 miles = 781440 yards.

So, there are 781440 yards in 444 miles.

Hence, there are 781440 yards in 444 miles.

You deposited 8500 dollars in a saving account that earns a simple interest rate. what interest rate do you need to be paid if y

V125BC [204]

Answer:

23.75%

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest,

P = principal,

r = rate (as decimal),

t = time (in years).

In your case,

$I=\$8,500\\ \\P=\$10,093.75\\ \\t=60\text{ months}=5 \text{ years}$

Substitute:

$10,093.75=8,500\cdot r\cdot 5\\ \\r=\dfrac{10,093.75}{8,500\cdot 5}=0.2375=23.75\%$

If f(x)=g(x)-10 and g(x)=3x-18 then what would the equation<br> represent f(x)

DanielleElmas [232]

Hello!

$\large\boxed{f(x) = 3x - 28}$

If f(x) = g(x)-10, substitute in the equation of g(x) to solve for f(x):

f(x) = (3x - 18) - 10

Simplify:

f(x) = 3x - 28
