Answer: c. y= 2x -3

Step-by-step explanation:

Slope Intercept Form: y= mx +b

m=slope

b= y intercept

the slope is 2 because the line "rises" 2 times and "runs" 1 time

rise/run

2/1

m=2

the y intercept is where the line crosses the (vertical) y-axis

on this graph the line crosses at (0,-3), therefore

b= -3

plug into Slope Intercept Form:

y= mx +b

y= 2x-3

Evaluate the line integral ∫CF⋅dr, where F(x,y,z)=5sinxi+4cosyj−2xzk and C is given by the vector function r(t)=t3i−t2j+t1k , 0≤

pickupchik [31]

$\mathbf r(t)=x(t)\,\mathbf i+y(t)\,\mathbf j+z(t)\,\mathbf k$
$\implies\begin{cases}x(t)=t^3\\y(t)=-t^2\\z(t)=t\end{cases}$
$\implies\dfrac{\mathrm d\mathbf r}{\mathrm dt}=3t^2\,\mathbf i-2t\,\mathbf j+\mathbf k$

with $0\le t\le1$ . With this parameterization, the vector field can be written as

$\mathbf F(x,y,z)=\mathbf F(x(t),y(t),z(t))=5\sin(t^3)\,\mathbf i+4\cos(t^2)\,\mathbf j-2t^4\,\mathbf k$

Now the line integral is given by

$\displaystyle\int_C\mathbf F\cdot\mathrm d\mathbf r=\int_{t=0}^{t=1}\mathbf F(x(t),y(t),z(t))\cdot\dfrac{\mathrm d\mathbf r(t)}{\mathrm dt}\,\mathrm dt$
$=\displaystyle\int_0^1(15t^2\sin(t^3)-8t\cos(t^2)-2t^4)\,\mathrm dt$
$=-5\cos1-4\sin1+\dfrac{23}5$

Z-2.3 = 0.46 what is z<br> Please help me

ddd [48]

Answer:

Z = 2.76

Step-by-step explanation:

Firstly you must realise that Z - 2.3 = 0.46

Therfore this means you must 2.3 to 0.46 to get Z

2.3+0.46+2.76

Delvig [45]

Answer:

1: 98

2: 82

3: 98

4: 82

Step-by-step explanation:

So 2 is 82deg then the opposite is also 82 so 4 is 82deg

Then 82+82 = 164deg, and we remain with 360deg-164deg which is = 196.

Since the other two angles will be equal (they are opposite each other) we can decide 196/2 = 98

So 3 and 1 are 98deg

Art [367]

Answer:

a. He read between 4 and 7 books.

b. x= 54/9

c. 6 books

Step-by-step explanation:

a. When I solved the equation, Finn read 6 six books which falls between 4 and 7 books.

b. You would divide 54 by 9 to find the number of books, he read. It would not make sense to multiply.

c. He read 6 books when we divide 54 by 9.
