Answer:

y=-3x+5

Step-by-step explanation:

concepts: y=mx+b is slope intercept equation formula

m=slope

b= y intercept

Therefore we need to find the slope and y intercept

first find slope

m=\frac{y2-y1}{x2-x1}

let y2 be 2

let y1 be -4

let x2 be 1

let x1 be 3

\frac{2-(--4)}{1-3}

6/-2 = -3

m=-3

slope is -3

y= -3x+ b

we need find y intercept now

just plug in (1,2) into that equation

2=-3(1)+b

b=5

y=-3x+5

Enter the equation of the circle described below.<br><br> Center (3, -2), radius = 5
Alik [6]

Answer:

(x-3)^{2} +(y+2)^{2} =5^{2}

Step-by-step explanation:

The equation of the circle with center A=(a,b) and radius = r are:

(x-a)^{2}+(y-b)^{2}  =r^{2}

When A=(3,-2) and radius=r=-5

(x-3)^{2} +(y+2)^{2} =5^{2}

What is the answer to this problem -2x – 4 &lt; 3x + 21
horsena [70]

Start with

-2x-4 < 3x+21

Add 2x to both sides:

-4 < 5x+21

Subtract 21 from both sides:

-25 < 5x

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

-5 < x

So, the answer is x > -5

If c is the curve given by \mathbf{r} \left( t \right = \left( 1 5 \sin t \right \mathbf{i} \left( 1 3 \sin^{2} t \right \mathbf
jonny [76]
With the curve C parameterized by

C:\mathbf r(t)=\underbrace{15\sin t}_{x(t)}\,\mathbf i+\underbrace{13\sin^2t}_{y(t)}\,\mathbf j+\underbrace{12\sin^3t}_{z(t)}\,\mathbf k

with 0\le t\le\dfrac\pi2, and given the vector field

\mathbf f(x,y,z)=x\,\mathbf i+y\,\mathbf j+z\,\mathbf k

the work done by \mathbf f on a particle moving on along C is given by the line integral

\displaystyle\int_C\mathbf f\cdot\mathrm d\mathbf r=\int\limits_{t=0}^{t=\pi/2}\mathbf f(x(t),y(t),z(t))\cdot\frac{\mathrm d\mathbf r(t)}{\mathrm dt}\,\mathrm dt

where

\mathrm d\mathbf r=(15\cos t\,\mathbf i+26\sin t\cos t\,\mathbf j+36\sin^2t\cos t\,\mathbf k)\,\mathrm dt

The integral is then

\displaystyle\int_0^{\pi/2}(15\sin t\,\mathbf i+13\sin^2t\,\mathbf j+12\sin^3t\,\mathbf k)\cdot(15\cos t\,\mathbf i+13\sin2t\,\mathbf j+18\sin t\sin2t\,\mathbf k)\,\mathrm dt
=\displaystyle\int_0^{\pi/2}(432\sin^5t\cos t+338\sin^3t\cos t+225\sin t\cos t

Find the lest number which is exactly divisible by 36 &amp; 90 Maths ​
prisoha [69]

Answer:

  • 180

Step-by-step explanation:

You need to find the HCF of 36 and 90.

<u>Prime factors of each:</u>

  • 36 = 2*2*3*3
  • 90 = 2*3*3*5

<u>HCF includes all prime factors of both numbers:</u>

  • HCF(36, 90) = 2*2*3*3*5 = 180
