40pages=2hours
40pages=2hours
40/2=20
20=1hour
40+40+20=100pages

You can read 100 pages in 5 hours.

40 pages in 2 hours. We need to get the unit rate. In this case, we need to get the number of pages read in 1 hour.

40 pages ÷ 2 hours = 20 pages per hour.

20 pages per hours * 5 hours = 100 pages.

Three-fifths of the sum of 9 and f

blsea [12.9K]

Answer: $\frac{3}{5} f+\frac{27}{5}$

Step-by-step explanation:

Three-fifths of the sum of 9 and f is $\frac{3}{5} (9+f)$ = $\frac{27}{5} +\frac{3}{5} f$ = $\frac{3}{5} f+\frac{27}{5}$

Answer:

sinH ≈ 0.47

Step-by-step explanation:

sinH = $\frac{opposite}{hypotenuse}$ = $\frac{IJ}{HJ}$ = $\frac{16}{34}$ ≈ 0.47 ( to the nearest hundredth )

What is the equation of the line that passes through the points (1, 1) and (7, -5)?

xxTIMURxx [149]

Answer:

y = -1x+2

Step-by-step explanation:

(1,1)(7,-5)

y2-y1/x2-x1 = slope

-5-1/7-1 = -6/6= -1

y-y1 = slope(x-x1) // equation formula

y-1=-1(x-1)

y = -1x + 1 +1

y = -1x+2

Consider f and c below. f(x, y) = x2 i + y2 j c is the arc of the parabola y = 2x2 from (−1, 2) to (1, 2) (a) find a function f

Korvikt [17]

If there is some scalar function $f(x,y)$ such that

$\nabla f(x,y)=\mathbf f(x,y)=x^2\,\mathbf i+y^2\,\mathbf j$

then we want to find $f$ such that

$\dfrac{\partial f}{\partial x}=x^2\implies f(x,y)=\dfrac{x^3}3+g(y)$
$\dfrac{\partial f}{\partial y}=y^2=\dfrac{\mathrm dg}{\mathrm dy}\implies g(y)=\dfrac{y^3}3+C$
$\implies f(x,y)=\dfrac{x^3}3+\dfrac{y^3}3+C$

So the vector field $\mathbf f(x,y)$ is conservative, which means the fundamental theorem applies; the line integral of $\mathbf f$ along any path $\mathcal C$ parameterized by some vector-valued function $\mathbf r(t)$ over $a\le t\le b$ is given by

$\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=\int_{t=a}^{t=b}\mathbf f(\mathbf r(t))\cdot\dfrac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt=f(\mathbf r(b))-f(\mathbf r(a))$

In this case,

$\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=f(1,2)-f(-1,2)=\dfrac23$
