Question 2

Llana [10]

Hi here are the answers:)

Part A:

x = 3

Part B:

A = (3, 2)

Part C:

You can find the vertex by finding the mid-point of the focus and directrix. So the vertex is (-1, 2)

Part D:

The parabola opens left. This is because the parabola always opens toward the focus.

Part E:

The value of p is the distance from the focus to the vertex or the vertex to the directrix. To find p you can minus x-coordinate of focus with x-coordinate of the directrix, then divide it by 2. So this will be: -5-2/2 = -4

Part F:

p = -4

Part G:

$x=\frac{1}{4*-4}(y-2)^{2}-1$

Part H: image is attached down below. Fyi the C should be V (vertex)

Part I:

$x=\frac{1}{16} (y-2)^{2}-1$

*I'm not really sure about this one*

Part J:

1. x = 1/4 (y-3)>2+3

2. x = 1/12 (y +1)>2 +5

*I'm not really sure about this one either srry:(*

Hope this helped bai bye.

Use the definition to find an expression for the area under the curve y = x3 from 0 to 1 as a limit. lim n→∞ n i = 1 R (b) The f

Harlamova29_29 [7]

The summand (R?) is missing, but we can always come up with another one.

Divide the interval [0, 1] into $n$ subintervals of equal length $\dfrac{1-0}n=\dfrac1n$ :

$[0,1]=\left[0,\dfrac1n\right]\cup\left[\dfrac1n,\dfrac2n\right]\cup\cdots\cup\left[1-\dfrac1n,1\right]$

Let's consider a left-endpoint sum, so that we take values of $f(\ell_i)={\ell_i}^3$ where $\ell_i$ is given by the sequence

$\ell_i=\dfrac{i-1}n$

with $1\le i\le n$ . Then the definite integral is equal to the Riemann sum

$\displaystyle\int_0^1x^3\,\mathrm dx=\lim_{n\to\infty}\sum_{i=1}^n\left(\frac{i-1}n\right)^3\frac{1-0}n$

$=\displaystyle\lim_{n\to\infty}\frac1{n^4}\sum_{i=1}^n(i-1)^3$

$=\displaystyle\lim_{n\to\infty}\frac1{n^4}\sum_{i=0}^{n-1}i^3$

$=\displaystyle\lim_{n\to\infty}\frac{n^2(n-1)^2}{4n^4}=\boxed{\frac14}$

Question will save this response.

serg [7]

Answer:

$r=\dfrac{PV}{nT}$

Step-by-step explanation:

The given equation is :

$PV=nrT$

Where

P is pressure

V is volume

n is no of moles

r is Gas constant

T is temperature

We need to solve the above equation for r.

Dividing both sides of the above equation by (nT). So,

$\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}$

So, the value of r is equal to $\dfrac{PV}{nT}$ .
