Zinaida [17]3 years ago

The main formula is integr U^p  du  = (1/1+p)U^p+1
let be U=<span>(25 - 16x^2)^-1/2,
</span>1/sqrt(25 - 16x^2) = (25 - 16x^2)^-1/2
du= -1/2)(-32x)(25 - 16x^2)^-1/2dx
integ du/-1/2)(-32x)= integ(25 - 16x^2)^-1/2dx
nteg du/16x)=1/16xu+c=integ(25 - 16x^2)^-1/2dx
finally 
integ 1 / sqrt(25 - 16x^2) dx  = 1/16xu+c= (1/16x)(<span>(25 - 16x^2)^-1/2) +c
</span>

A line includes the points (0,0) and (1,5). What is its equation in slope-intercept form
Kipish [7]

9514 1404 393

Answer:

  y = 5x

Step-by-step explanation:

The point (0, 0) tells you the line goes through the origin, so represents a proportional relationship. The slope is simply the ratio of y to x, or 5/1 = 5.

The equation of the line is ...

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

  y = 5x . . . . . . . . . . line with slope 5 and y-intercept of 0 (the origin)
