Given directed line segment AB determine point X on the graph such that X partions the segment A to B in a ratio of 1:4 and give

Viktor [21]

Answer:

The coordinates of point X that divides the line in 1:4 are: (3,8/5)

Step-by-step explanation:

When a point divides a line with coordinates (x1,y1) and (x2,y2) in ratio m:n,

the coordinates of point are given by:

$(x,y) = (\frac{mx_2+nx_1}{m+n} , \frac{my_2+ny_1}{m+n})$

Given points are:

(x1,y1) = (5,1)

(x2,y2) = (-5,4)

Putting the values in the formula

$X(x,y) = (\frac{(1)(-5)+(4)(5)}{1+4} , \frac{(1)(4)+(4)(1)}{1+4})\\= (\frac{-5+20}{5}, \frac{4+4}{5})\\=(\frac{15}{5}, \frac{8}{5})\\=(3,\frac{8}{5})$

Hence,

The coordinates of point X that divides the line in 1:4 are: (3,8/5)

Find the surface area of a cylinder that has the following information:

BigorU [14]

Answer:

$A=1099.56cm^{2}$

Step-by-step explanation:

Formula to ind surface area of cylinder:

$A=2\pi \frac{d}{2} h+2\pi (\frac{d}{2} )^{2}$

$A=2\pi \frac{10}{2} (30)+2\pi (\frac{10}{2} )^{2}$

$A=1099.557443cm^{2}$

Therefore, area will be:

$A=1099.56cm^{2}$

Find the smallest zero for the function h(x)=4x^2-8x-60.

ankoles [38]

H(x) = 4x² - 8x - 60
0 = 4x² - 8x - 60
  0 = 4(x²) - 4(2x) - 4(15)
  0 = 4(x² - 2x - 15)
4 4
0 = x² - 2x - 15
0 = x² - 5x + 3x - 15
0 = x(x) - x(5) + 3(x) - 3(5)
0 = x(x - 5) + 3(x - 5)
0 = (x + 3)(x - 5)
0 = x + 3 or 0 = x - 5
- 3 - 3 + 5 + 5
3 = x    or    5 = x
