linear equation in point slope form for a line that passes through the point (3,2) and has a slope of -4

RoseWind [281]

Answer:

Step-by-step explanation:

The point-slope equation of a line is ...

y -k = m(x -h) . . . . . . line through point (h, k) with slope m

For (h, k) = (3, 2), and m = -4, the equation of the line is ...

y -2 = -4(x -3)

O is the center of both circles containing arcs AB and CD

victus00 [196]

Answer:

Step-by-step explanation:

You need to solve the area sector of the bigger circle. Since we now the length of sector is 270, we can set up an equation.

Length of sector DC = 2 $\pi$ r

270 = 2 $\pi$ (8+OA) *(8+OA is the raidus of the bigger circle/sector)*

270/2 $\pi$ = 8 + OA (division)

135/ $\pi$ -8 = OA

135/ $\pi$ -8 = OB (because OA and OB are the raidus of the same circle, so they are congruent)

I hope this helps you! Please correct me if you see a miscalculation <3<3

The volume inside of a sphere is V=4πr33 where r is the radius of the sphere. Your group has been asked to rearrange the formula

Semmy [17]

Answer:

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

Step-by-step explanation:

Given:

Volume of inside of the sphere is given as

$V=\frac{4}{3} \pi r^{3}$

where r is the radius of the sphere

To Find:

r =?

Solution:

We have

$V=\frac{4}{3} \pi r^{3}$ ......Given

$3\times V=4\pi r^{3} \\\\\therefore r^{3}=\frac{3V}{4\pi } \\\\\therefore r=\sqrt[3]{\frac{3V}{4\pi }} \textrm{which is the expression for r}$

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

A bowl of spaghetti contains 5 grams of fiber. It is recommended for a person to eat 34 grams of fiber in a day. If you ate 3.5

puteri [66]

Answer: 51 %

Step-by-step explanation:

3.5 * 5 = 17.5

17.5 = x/100 * 34

17.5 = 34x/100

17.5 * 100 = 34x

1750 = 34x

x = 1750/34

x = 51.47

rounded to 51%
