Answer:

  y = 4/3(x +3)

Step-by-step explanation:

This sort of question is easily answered by making use of the point-slope form of the equation of a line:

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

You are given (h, k) = (-3, 0) and m = 4/3. Putting those into the above form gives ...

  y -0 = 4/3(x -(-3))

  y = 4/3(x +3) . . . . . . point-slope form equation

__

<em>Additional comment</em>

You can use the distributive property to eliminate the parentheses. That puts the equation into slope-intercept form.

  y = 4/3x +(4/3)(3)

  y = 4/3x +4 . . . . . . slope-intercept equation

__

You may find it useful to remember some different forms of the equation for a line:

  y = mx +b . . . . . line with slope m and y-intercept b

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

  ax +by = c . . . . standard form equation of a line, where a > 0, and a, b, c are mutually prime integers

The volume of a beack ball is 905 square centimeters. Find the radius of the ball to the nearest whole number.​
lubasha [3.4K]
<h3>given:</h3>

v = 905 \:  {cm}^{3}

<h3>to find:</h3>

the radius of the given ball (sphere).

<h3>solution:</h3>

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

r =  \sqrt[3]{ \frac{3 \times 905}{4\pi} }

r = 6 \: cm

<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>ball</u><u> </u><u>is</u><u> </u><u>6</u><u> </u><u>cm</u><u>.</u>

note: refer to the picture I added on how you can change r as the subject of the formula.

the sum of the first six terms of a geometric series is 21/16 . if the common ratio is -1/2 , what is the first term?
Oksanka [162]

Answer:

-84

Step-by-step explanation:

The formula for the nth term of a geometric progression is

Un = ar^n- 1

The sum of the first six terms of a geometric series (U6) = 21/16

Common ratio = -1/2 ,

a = First term ??

21/16 = a × (-1/2 )^6- 1

21/16 = a ×(-2^-1)^5

21/16 = a × -2^-6

Cross Multiply

16 × a × -2^-6 = 21

a = 21/16 × -2^-6

a = 21/16 ×- 1/2⁶

a = 21/16 × -1/64

a = 21 ÷(-1/4)

a = 21 × -4

a = -84

The first term = 84
